Refactor the code which checks to see if we need to use non-global
mappings to use a variable instead of checking with the CPU capabilities
each time, doing the initial check for KPTI early in boot before we
start allocating memory so we still avoid transitioning to non-global
mappings in common cases.
Since this variable always matches our decision about non-global
mappings this means we can also combine arm64_kernel_use_ng_mappings()
and arm64_unmap_kernel_at_el0() into a single function, the variable
simply stores the result and the decision code is elsewhere. We could
just have the users check the variable directly but having a function
makes it clear that these uses are read-only.
The result is that we simplify the code a bit and reduces the amount of
code executed at runtime.

Since E0PD is intended to fulfil the same role as KPTI we don't need to
use KPTI on CPUs where E0PD is available, we can rely on E0PD instead.
Change the check that forces KPTI on when KASLR is enabled to check for
E0PD before doing so, CPUs with E0PD are not expected to be affected by
meltdown so should not need to enable KPTI for other reasons.
Since E0PD is a system capability we will still enable KPTI if any of
the CPUs in the system lacks E0PD, this will rewrite any global mappings
that were established in systems where some but not all CPUs support
E0PD. We may transiently have a mix of global and non-global mappings
while booting since we use the local CPU when deciding if KPTI will be
required prior to completing CPU enumeration but any global mappings
will be converted to non-global ones when KPTI is applied.
KPTI can still be forced on from the command line if required.

Kernel Page Table Isolation (KPTI) is used to mitigate some speculation
based security issues by ensuring that the kernel is not mapped when
userspace is running but this approach is expensive and is incompatible
with SPE. E0PD, introduced in the ARMv8.5 extensions, provides an
alternative to this which ensures that accesses from userspace to the
kernel's half of the memory map to always fault with constant time,
preventing timing attacks without requiring constant unmapping and
remapping or preventing legitimate accesses.
Currently this feature will only be enabled if all CPUs in the system
support E0PD, if some CPUs do not support the feature at boot time then
the feature will not be enabled and in the unlikely event that a late
CPU is the first CPU to lack the feature then we will reject that CPU.
This initial patch does not yet integrate with KPTI, this will be dealt
with in followup patches. Ideally we could ensure that by default we
don't use KPTI on CPUs where E0PD is present.

We detect the absence of FP/SIMD after an incapable CPU is brought up,
and by then we have kernel threads running already with TIF_FOREIGN_FPSTATE set
which could be set for early userspace applications (e.g, modprobe triggered
from initramfs) and init. This could cause the applications to loop forever in
do_nofity_resume() as we never clear the TIF flag, once we now know that
we don't support FP.
Fix this by making sure that we clear the TIF_FOREIGN_FPSTATE flag
for tasks which may have them set, as we would have done in the normal
case, but avoiding touching the hardware state (since we don't support any).
Also to make sure we handle the cases seemlessly we categorise the
helper functions to two :
1) Helpers for common core code, which calls into take appropriate
actions without knowing the current FPSIMD state of the CPU/task.
e.g fpsimd_restore_current_state(), fpsimd_flush_task_state(),
fpsimd_save_and_flush_cpu_state().
We bail out early for these functions, taking any appropriate actions
(e.g, clearing the TIF flag) where necessary to hide the handling
from core code.
2) Helpers used when the presence of FP/SIMD is apparent.
i.e, save/restore the FP/SIMD register state, modify the CPU/task
FP/SIMD state.
e.g,
fpsimd_save(), task_fpsimd_load() - save/restore task FP/SIMD registers
fpsimd_bind_task_to_cpu() \
- Update the "state" metadata for CPU/task.
fpsimd_bind_state_to_cpu() /
fpsimd_update_current_state() - Update the fp/simd state for the current
task from memory.
These must not be called in the absence of FP/SIMD. Put in a WARNING
to make sure they are not invoked in the absence of FP/SIMD.
KVM also uses the TIF_FOREIGN_FPSTATE flag to manage the FP/SIMD state
on the CPU. However, without FP/SIMD support we trap all accesses and
inject undefined instruction. Thus we should never "load" guest state.
Add a sanity check to make sure this is valid.

We finalize the system wide capabilities after the SMP CPUs
are booted by the kernel. This is used as a marker for deciding
various checks in the kernel. e.g, sanity check the hotplugged
CPUs for missing mandatory features.
However there is no explicit helper available for this in the
kernel. There is sys_caps_initialised, which is not exposed.
The other closest one we have is the jump_label arm64_const_caps_ready
which denotes that the capabilities are set and the capability checks
could use the individual jump_labels for fast path. This is
performed before setting the ELF Hwcaps, which must be checked
against the new CPUs. We also perform some of the other initialization
e.g, SVE setup, which is important for the use of FP/SIMD
where SVE is supported. Normally userspace doesn't get to run
before we finish this. However the in-kernel users may
potentially start using the neon mode. So, we need to
reject uses of neon mode before we are set. Instead of defining
a new marker for the completion of SVE setup, we could simply
reuse the arm64_const_caps_ready and enable it once we have
finished all the setup. Also we could expose this to the
various users as "system_capabilities_finalized()" to make
it more meaningful than "const_caps_ready".

Merge tag 'clone3-tls-v5.5-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux
Pull thread fixes from Christian Brauner:
"This contains a series of patches to fix CLONE_SETTLS when used with
clone3().
The clone3() syscall passes the tls argument through struct clone_args
instead of a register. This means, all architectures that do not
implement copy_thread_tls() but still support CLONE_SETTLS via
copy_thread() expecting the tls to be located in a register argument
based on clone() are currently unfortunately broken. Their tls value
will be garbage.
The patch series fixes this on all architectures that currently define
__ARCH_WANT_SYS_CLONE3. It also adds a compile-time check to ensure
that any architecture that enables clone3() in the future is forced to
also implement copy_thread_tls().
My ultimate goal is to get rid of the copy_thread()/copy_thread_tls()
split and just have copy_thread_tls() at some point in the not too
distant future (Maybe even renaming copy_thread_tls() back to simply
copy_thread() once the old function is ripped from all arches). This
is dependent now on all arches supporting clone3().
While all relevant arches do that now there are still four missing:
ia64, m68k, sh and sparc. They have the system call reserved, but not
implemented. Once they all implement clone3() we can get rid of
ARCH_WANT_SYS_CLONE3 and HAVE_COPY_THREAD_TLS.
This series also includes a minor fix for the arm64 uapi headers which
caused __NR_clone3 to be missing from the exported user headers.
Unfortunately the series came in a little late especially given that
it touches a range of architectures. Due to the holidays not all arch
maintainers responded in time probably due to their backlog. Will and
Arnd have thankfully acked the arm specific changes.
Given that the changes are straightforward and rather minimal combined
with the fact the that clone3() with CLONE_SETTLS is broken I decided
to send them post rc3 nonetheless"

New boards are the Radxa Rock Pi N10 using the VMARC SOM and Dalang
carrier board, separate versions for the two rockpro64 hardware revisions
which switched a pin between revisions. The rockpro64 also got
bluetooth support now.
The px30 got a lot of attention with dsi, gpu and thermal support.
Similarly the rk3399-roc-pc board also got attention with mtd flash,
sdr104 mode, hdmi sound, gpu and a lot of other smaller improvements.
Other than that there is a new gpu-cooling device for rk3399 a cpu
idle-state for rk3328 and more small improvements across a number
of boards.

The memory subsystem on Tegra194 encompasses both the memory and
external memory controllers. The EMC is represented as a subnode of the
MC and a ranges property is used to describe the register ranges.
A dma-ranges property is also added to describe that all memory clients
can address up to 39 bits using the memory controller client interface
(MCCIF), unless otherwise limited by the DMA engines of the hardware. A
memory client can technically use 40 bits of addresses, but the memory
controller on Tegra194 uses bit 39 to determine the XBAR format used to
access memory. Use of this bit needs to be explicitly controlled by the
operating system drivers for devices that can use this on-the-fly format
conversion. Using the dma-ranges property prevents the operating system
from using the bit implicitly, for example in I/O virtual address
mappings.

Add the external memory controller as a child device of the memory

The CRYPTO_TFM_RES_BAD_KEY_LEN flag was apparently meant as a way to
make the ->setkey() functions provide more information about errors.
However, no one actually checks for this flag, which makes it pointless.
Also, many algorithms fail to set this flag when given a bad length key.
Reviewing just the generic implementations, this is the case for
aes-fixed-time, cbcmac, echainiv, nhpoly1305, pcrypt, rfc3686, rfc4309,
rfc7539, rfc7539esp, salsa20, seqiv, and xcbc. But there are probably
many more in arch/*/crypto/ and drivers/crypto/.
Some algorithms can even set this flag when the key is the correct
length. For example, authenc and authencesn set it when the key payload
is malformed in any way (not just a bad length), the atmel-sha and ccree
drivers can set it if a memory allocation fails, and the chelsio driver
sets it for bad auth tag lengths, not just bad key lengths.
So even if someone actually wanted to start checking this flag (which
seems unlikely, since it's been unused for a long time), there would be
a lot of work needed to get it working correctly. But it would probably
be much better to go back to the drawing board and just define different
return values, like -EINVAL if the key is invalid for the algorithm vs.
-EKEYREJECTED if the key was rejected by a policy like "no weak keys".
That would be much simpler, less error-prone, and easier to test.
So just remove this flag.

type, but is actually a pointers in the current virtual space. This
is confusing to read.
Rename dst to more appropriate page (page that is created), and also
change its time to "void *"

create_safe_exec_page() uses hibernate's allocator to create a set of page
table to map a single page that will contain the relocation code.
Remove the allocator related arguments, and use get_safe_page directly, as
it is done in other local functions in this file to simplify function
prototype.
Removing this function pointer makes it easier to refactor the code later.

As part of an effort to make the annotations in assembly code clearer and

for ENTRY() and ENDPROC().
On arm64 we have ENDPIPROC(), a custom version of ENDPROC() which is
used for code that will need to run in position independent environments
like EFI, it creates an alias for the function with the prefix __pi_ and
then emits the standard ENDPROC. Add new-style macros to replace this
which expand to the standard SYM_FUNC_*() and SYM_FUNC_ALIAS_*(),
resulting in the same object code. These are added in linkage.h for
consistency with where the generic assembler code has its macros.

vdd_apc is the regulator that supplies the main CPU cluster.
At sudden CPU load changes, we have noticed invalid page faults on
addresses with all bits shifted, as well as on addresses with individual
bits flipped.
By putting the vdd_apc regulator in high power mode, the voltage drops
during sudden load changes will be less severe, and we have not been able
to reproduce the invalid page faults with the regulator in this mode.

The ARMv8 64-bit architecture supports execute-only user permissions by
clearing the PTE_USER and PTE_UXN bits, practically making it a mostly
privileged mapping but from which user running at EL0 can still execute.
The downside, however, is that the kernel at EL1 inadvertently reading
such mapping would not trip over the PAN (privileged access never)
protection.
Revert the relevant bits from commit cab15ce604 ("arm64: Introduce
execute-only page access permissions") so that PROT_EXEC implies
PROT_READ (and therefore PTE_USER) until the architecture gains proper
support for execute-only user mappings.

As R-Car H3 ES1.x (R8A77950) and R-Car H3 ES2.0+ (R8A77951) are really

Unlike the V3MSK and V3HSK boards, the various "ULCB" boards are really
the same boards, with different SiPs fitted, just like the Salvator-X(S)
boards. Furthermore, the "H3", "M3", and "M3N" prefixes of the "ULCB"
parts in the DTS file names are redundant, as they are implied by the
SoC part numbers, which are also part of the file names.
Hence drop the redundant prefixes, to make the DTS file names consistent
with the file names for the various "Salvator-X(S)" boards.

historical reasons, R-Car H3 ES1.x (R8A77950) and R-Car H3 ES2.0+
(R8A77951) are really different SoCs, with different part numbers.
Reflect this in the DTS files by changing their base names from

Drop all "ES" references next to part numbers, as they are implied by

====================
pull-request: bpf-next 2019-12-27
The following pull-request contains BPF updates for your *net-next* tree.
We've added 127 non-merge commits during the last 17 day(s) which contain
a total of 110 files changed, 6901 insertions(+), 2721 deletions(-).
There are three merge conflicts. Conflicts and resolution looks as follows:
1) Merge conflict in net/bpf/test_run.c:
There was a tree-wide cleanup c593642c8b ("treewide: Use sizeof_field() macro")
which gets in the way with b590cb5f80 ("bpf: Switch to offsetofend in
BPF_PROG_TEST_RUN"):
<<<<<<< HEAD
if (!range_is_zero(__skb, offsetof(struct __sk_buff, priority) +
sizeof_field(struct __sk_buff, priority),
=======
if (!range_is_zero(__skb, offsetofend(struct __sk_buff, priority),
>>>>>>> 7c8dce4b16
There are a few occasions that look similar to this. Always take the chunk with
offsetofend(). Note that there is one where the fields differ in here:
<<<<<<< HEAD
if (!range_is_zero(__skb, offsetof(struct __sk_buff, tstamp) +
sizeof_field(struct __sk_buff, tstamp),
=======
if (!range_is_zero(__skb, offsetofend(struct __sk_buff, gso_segs),
>>>>>>> 7c8dce4b16
Just take the one with offsetofend() /and/ gso_segs. Latter is correct due to
850a88cc40 ("bpf: Expose __sk_buff wire_len/gso_segs to BPF_PROG_TEST_RUN").
2) Merge conflict in arch/riscv/net/bpf_jit_comp.c:
(I'm keeping Bjorn in Cc here for a double-check in case I got it wrong.)
<<<<<<< HEAD
if (is_13b_check(off, insn))
return -1;
emit(rv_blt(tcc, RV_REG_ZERO, off >> 1), ctx);
=======
emit_branch(BPF_JSLT, RV_REG_T1, RV_REG_ZERO, off, ctx);
>>>>>>> 7c8dce4b16
Result should look like:
emit_branch(BPF_JSLT, tcc, RV_REG_ZERO, off, ctx);
3) Merge conflict in arch/riscv/include/asm/pgtable.h:
<<<<<<< HEAD
=======
#define VMALLOC_SIZE (KERN_VIRT_SIZE >> 1)
#define VMALLOC_END (PAGE_OFFSET - 1)
#define VMALLOC_START (PAGE_OFFSET - VMALLOC_SIZE)
#define BPF_JIT_REGION_SIZE (SZ_128M)

#define VMEMMAP_START (VMALLOC_START - VMEMMAP_SIZE)
#define vmemmap ((struct page *)VMEMMAP_START)
>>>>>>> 7c8dce4b16
Only take the BPF_* defines from there and move them higher up in the
same file. Remove the rest from the chunk. The VMALLOC_* etc defines
got moved via 01f52e16b8 ("riscv: define vmemmap before pfn_to_page

Let me know if there are any other issues.
Anyway, the main changes are:
1) Extend bpftool to produce a struct (aka "skeleton") tailored and specific
to a provided BPF object file. This provides an alternative, simplified API
compared to standard libbpf interaction. Also, add libbpf extern variable
resolution for .kconfig section to import Kconfig data, from Andrii Nakryiko.
2) Add BPF dispatcher for XDP which is a mechanism to avoid indirect calls by
generating a branch funnel as discussed back in bpfconf'19 at LSF/MM. Also,
add various BPF riscv JIT improvements, from Björn Töpel.
3) Extend bpftool to allow matching BPF programs and maps by name,
from Paul Chaignon.
4) Support for replacing cgroup BPF programs attached with BPF_F_ALLOW_MULTI
flag for allowing updates without service interruption, from Andrey Ignatov.
5) Cleanup and simplification of ring access functions for AF_XDP with a
bonus of 0-5% performance improvement, from Magnus Karlsson.
6) Enable BPF JITs for x86-64 and arm64 by default. Also, final version of
audit support for BPF, from Daniel Borkmann and latter with Jiri Olsa.
7) Move and extend test_select_reuseport into BPF program tests under
BPF selftests, from Jakub Sitnicki.
8) Various BPF sample improvements for xdpsock for customizing parameters
to set up and benchmark AF_XDP, from Jay Jayatheerthan.
9) Improve libbpf to provide a ulimit hint on permission denied errors.
Also change XDP sample programs to attach in driver mode by default,
from Toke Høiland-Jørgensen.
10) Extend BPF test infrastructure to allow changing skb mark from tc BPF
programs, from Nikita V. Shirokov.
11) Optimize prologue code sequence in BPF arm32 JIT, from Russell King.
12) Fix xdp_redirect_cpu BPF sample to manually attach to tracepoints after
libbpf conversion, from Jesper Dangaard Brouer.
13) Minor misc improvements from various others.

The Libre Computer ALL-H3-IT board is a small single board computer that
is roughly the same size as the Raspberry Pi Zero, or around 20% smaller
than a credit card.
The board features:
- H2, H3, or H5 SoC from Allwinner
- 2 DDR3 DRAM chips
- Realtek RTL8821CU based WiFi module
- 128 Mbit SPI-NOR flash
- micro-SD card slot
- micro HDMI video output
- FPC connector for camera sensor module
- generic Raspberri-Pi style 40 pin GPIO header
- additional pin headers for extra USB host ports, ananlog audio and
IR receiver
Only H5 variant test samples were made available, but the vendor does
have plans to include at least an H3 variant. Thus the device tree is
split much like the ALL-H3-CC, with a common dtsi file for the board
design, and separate dts files including the common board file and the
SoC dtsi file. The other variants will be added as they are made
available.

The macros efi_call_early and efi_call_runtime are used to call EFI
boot services and runtime services, respectively. However, the naming
is confusing, given that the early vs runtime distinction may suggest
that these are used for calling the same set of services either early
or late (== at runtime), while in reality, the sets of services they
can be used with are completely disjoint, and efi_call_runtime is also
only usable in 'early' code.
So do a global sweep to replace all occurrences with efi_bs_call or
efi_rt_call, respectively, where BS and RT match the idiom used by
the UEFI spec to refer to boot time or runtime services.
While at it, use 'func' as the macro parameter name for the function
pointers, which is less likely to collide and cause weird build errors.

The efi_call macros on ARM have a dependency on a variable 'sys_table_arg'
existing in the scope of the macro instantiation. Since this variable
always points to the same data structure, let's create a global getter
for it and use that instead.
Note that the use of a global variable with external linkage is avoided,
given the problems we had in the past with early processing of the GOT
tables.
While at it, drop the redundant casts in the efi_table_attr and
efi_call_proto macros.

Currently, we support mixed mode by casting all boot time firmware
calls to 64-bit explicitly on native 64-bit systems, and to 32-bit
on 32-bit systems or 64-bit systems running with 32-bit firmware.
Due to this explicit awareness of the bitness in the code, we do a
lot of casting even on generic code that is shared with other
architectures, where mixed mode does not even exist. This casting
leads to loss of coverage of type checking by the compiler, which
we should try to avoid.
So instead of distinguishing between 32-bit vs 64-bit, distinguish
between native vs mixed, and limit all the nasty casting and
pointer mangling to the code that actually deals with mixed mode.

Commit f4a73f5e26 ("pinctrl: qcom: sc7180: Add new qup functions")
has landed which means that we absolutely need to use the proper names
for the pinmuxing for I2C/UART numbers 2, 4, 7, and 9. Let's do it.
For reference:
- If you get only one of this commit and the pinctrl commit then none
of I2C/UART 2, 4, 7, and 9 will work.
- If you get neither of these commits then I2C 2, 4, 7, and 9 will
work but not UART.
...but despite the above it should be fine for this commit to land in
the Qualcomm tree because sc7180.dtsi only exists there (it hasn't
made it to mainline).

The bindings for the QMP PHY are truly strange. I believe (?) that
they may have originated because with PCIe each lane is treated as a
different PHY and the same PHY driver is used for a whole bunch of
things (incluidng PCIe).
In any case, now that we have "make dtbs_check", we find that having
the outer node named "phy" triggers the
"schemas/phy/phy-provider.yaml" schema, yelling about:
phy@88e9000: '#phy-cells' is a required property
Let's call the outer node the "phy-wrapper" and the inner node the
"phy" to make dtbs_check happy.

Commit 4b927b94d5 ("KVM: arm/arm64: vgic: Introduce find_reg_by_id()")
introduced 'find_reg_by_id()', which looks up a system register only if
the 'id' index parameter identifies a valid system register. As part of
the patch, existing callers of 'find_reg()' were ported over to the new
interface, but this breaks 'index_to_sys_reg_desc()' in the case that the
initial lookup in the vCPU target table fails because we will then call
into 'find_reg()' for the system register table with an uninitialised
'param' as the key to the lookup.
GCC 10 is bright enough to spot this (amongst a tonne of false positives,
but hey!):
| arch/arm64/kvm/sys_regs.c: In function ‘index_to_sys_reg_desc.part.0.isra’:
| arch/arm64/kvm/sys_regs.c:983:33: warning: ‘params.Op2’ may be used uninitialized in this function [-Wmaybe-uninitialized]
| 983 | (u32)(x)->CRn, (u32)(x)->CRm, (u32)(x)->Op2);
| [...]
Revert the hunk of 4b927b94d5 which breaks 'index_to_sys_reg_desc()' so
that the old behaviour of checking the index upfront is restored.

The Dragonboard-410c is able to act either as USB Host or Device.
The role can be determined at runtime via the USB_HS_ID pin which is

In Host role, SoC USB D+/D- are routed to the onboard USB 2.0 HUB.
In Device role, SoC USB D+/D- are routed to the USB 2.0 micro B port.
Routing is selected via USB_SW_SEL_PM gpio.
In device role USB HUB can be held in reset.

After Spectre 2 fix via 290af86629 ("bpf: introduce BPF_JIT_ALWAYS_ON
config") most major distros use BPF_JIT_ALWAYS_ON configuration these days
which compiles out the BPF interpreter entirely and always enables the
JIT. Also given recent fix in e1608f3fa8 ("bpf: Avoid setting bpf insns
pages read-only when prog is jited"), we additionally avoid fragmenting
the direct map for the BPF insns pages sitting in the general data heap
since they are not used during execution. Latter is only needed when run
through the interpreter.
Since both x86 and arm64 JITs have seen a lot of exposure over the years,
are generally most up to date and maintained, there is more downside in
!BPF_JIT_ALWAYS_ON configurations to have the interpreter enabled by default
rather than the JIT. Add a ARCH_WANT_DEFAULT_BPF_JIT config which archs can
use to set the bpf_jit_{enable,kallsyms} to 1. Back in the days the
bpf_jit_kallsyms knob was set to 0 by default since major distros still
had /proc/kallsyms addresses exposed to unprivileged user space which is
not the case anymore. Hence both knobs are set via BPF_JIT_DEFAULT_ON which
is set to 'y' in case of BPF_JIT_ALWAYS_ON or ARCH_WANT_DEFAULT_BPF_JIT.

The LS1028A SoC has only unidirectional SAIs. Therefore, it doesn't make
sense to have the RX and TX part synchronous. Even worse, the RX part
wont work out of the box because by default it is configured as
synchronous to the TX part. And as said before, the pinmux of the SoC
can only be configured to route either the RX or the TX signals to the
SAI but never both at the same time. Thus configure the asynchronous
mode by default.

The current sun50i-h6-pine-h64 DT does not specify which model (A or B)

When this file was created, only modelA was existing, but now both model
exists and with the time, this DT drifted to support the model B since it is
the most common one.
Furtheremore, some part of the model A does not work with it like ethernet and
HDMI connector (as confirmed by Jernej on IRC).
So it is time to settle the issue, and the easiest way was to state that
this DT is for model B.
Easiest since only a small name changes is required.
Doing the opposite (stating this file is for model A) will add changes (for

The SFP cages are designed to support up to 3W modules, such as G.hn,
G.fast and MoCA modules. Although there is no way for such modules to
declare to software that they consume 3W, we document in DT that this
is the designed power level for these cages.

The I2C bus violates the timing specifications when run in fast mode

The uDPU uses both ethernet controllers, which ties up COMPHY 0 for
eth1 and COMPHY 1 for eth0, with no USB3 comphy. The addition of
COMPHY support made the kernel override the setup by the boot loader
breaking this platform by assuming that COMPHY 0 was always used for
USB3. Delete the USB3 COMPHY definition at platform level, and add
phy specifications for the ethernet channels.

The min/max value of vdd_log is decide by pwm IO voltage and its
resistors, the rk3399-firefly board's pwm regulator circuit is designed
for IO voltage at 1.8V, while the board actually use 3.0V for IO, which
at last lead to the min-microvolt to '430mV' instead of '800mV'.

On rk3399 vdd_log shall not exceed 1.0 V. On rk3399-roc-pc
vdd_log is presently 1118 mV. Fix by setting the min voltage
of the respective pwm-regulator down to 450 mV.
This results in a vdd_log of 953 mV.
Specify the supply to silence warning.

Working with rootfs on two 128GB mmcs on rk3399-roc-pc.
One (mmc name 128G72, one screw hole) works fine in HS400 mode.
Other (mmc name DJNB4R, firefly on pcb, two screw holes) gets lots of
mmc1: "running CQE recovery", even hangs with damaged fs,
when running under heavy load, e.g. compiling kernel.
Both run fine with HS200.
Disabling CQ with patch mmc: core: Add MMC Command Queue Support kernel parameter [0] did not help.
[0] 54e264154b
Therefore I propose to disable HS400 mode on roc-pc for now.
