Steve Capper f0b38d65c9 arm64: hugetlb: remove spurious calls to huge_ptep_offset()
We don't need to call huge_ptep_offset as our accessors are already
supplied with the pte_t *.  This patch removes those spurious calls.

Steve Capper bb9dd3df8e arm64: hugetlb: refactor find_num_contig()
Patch series "Support for contiguous pte hugepages", v4.

This patchset updates the hugetlb code to fix issues arising from
contiguous pte hugepages (such as on arm64).  Compared to v3, This
version addresses a build failure on arm64 by including two cleanup
patches.  Other than the arm64 cleanups, the rest are generic code
changes.  The remaining arm64 support based on these patches will be
posted separately.  The patches are based on v4.12-rc2.  Previous
related postings can be found at [0], [1], [2], and [3].

The patches fall into three categories -

* Patch 1-2 - arm64 cleanups required to greatly simplify changing
  huge_pte_offset() prototype in Patch 5.

  Catalin, Will - are you happy for these patches to go via mm?

* Patches 3-4 address issues with gup

* Patches 5-8 relate to passing a size argument to hugepage helpers to
  disambiguate the size of the referred page. These changes are
  required to enable arch code to properly handle swap entries for
  contiguous pte hugepages.

  The changes to huge_pte_offset() (patch 5) touch multiple
  architectures but I've managed to minimise these changes for the
  other affected functions - huge_pte_clear() and set_huge_pte_at().

These patches gate the enabling of contiguous hugepages support on arm64
which has been requested for systems using !4k page granule.

The ARM64 architecture supports two flavours of hugepages -

* Block mappings at the pud/pmd level

  These are regular hugepages where a pmd or a pud page table entry
  points to a block of memory. Depending on the PAGE_SIZE in use the
  following size of block mappings are supported -

          PMD	PUD
          ---	---
  4K:      2M	 1G
  16K:    32M
  64K:   512M

  For certain applications/usecases such as HPC and large enterprise
  workloads, folks are using 64k page size but the minimum hugepage size
  of 512MB isn't very practical.

To overcome this ...

* Using the Contiguous bit

  The architecture provides a contiguous bit in the translation table
  entry which acts as a hint to the mmu to indicate that it is one of a
  contiguous set of entries that can be cached in a single TLB entry.

  We use the contiguous bit in Linux to increase the mapping size at the
  pmd and pte (last) level.

  The number of supported contiguous entries varies by page size and
  level of the page table.

  Using the contiguous bit allows additional hugepage sizes -

           CONT PTE    PMD    CONT PMD    PUD
           --------    ---    --------    ---
    4K:         64K     2M         32M     1G
    16K:         2M    32M          1G
    64K:         2M   512M         16G

  Of these, 64K with 4K and 2M with 64K pages have been explicitly
  requested by a few different users.

Entries with the contiguous bit set are required to be modified all
together - which makes things like memory poisoning and migration
impossible to do correctly without knowing the size of hugepage being
dealt with - the reason for adding size parameter to a few of the
hugepage helpers in this series.

This patch (of 8):

As we regularly check for contiguous pte's in the huge accessors, remove
this extra check from find_num_contig.

Aneesh Kumar K.V e1073d1e79 mm/hugetlb: clean up ARCH_HAS_GIGANTIC_PAGE
This moves the #ifdef in C code to a Kconfig dependency.  Also we move
the gigantic_page_supported() function to be arch specific.

This allows architectures to conditionally enable runtime allocation of
gigantic huge page.  Architectures like ppc64 supports different
gigantic huge page size (16G and 1G) based on the translation mode
selected.  This provides an opportunity for ppc64 to enable runtime
allocation only w.r.t 1G hugepage.

No functional change in this patch.

Linus Torvalds 19964541c2 ARM: SoC 64-bit changes
Changes to platform code for 64-bit ARM platforms.
 
 Andreas Färber adds two new platforms with initial code: Realtek RTD1295
 and Action Semi S900. Both are fairly similar chips, used mainly in
 set-top-boxes, but with other possible applications, and additional
 members in the respective product families that could be added in the
 future. The code here is fairly minimal, as all the interesting parts
 are in device drivers and dts files.
 
 The Broadcom Vulcan platform gets dropped, as no products ever became
 available, and Cavium integrated the platform under a new name.
 
 Among some other defconfig changes, Timur Tabi enables a number of
 options that are typically required for server platforms.

 A significant portion this time is due to added machine support:
 
 - Initial support for the Realtek RTD1295 SoC, along with the Zidoo
   X9S set-top-box
 
 - Initial support for Actions Semi S900 and the Bubblegum-96
   single-board-cёmputer.
 
 - Rockchips support for the rk3399-Firefly single-board-computer
   gets added, this one stands out for being relatively fast,
   affordable and well₋supported, compared to many boards that
   only fall into one or two of the above categories.
 
 - Mediatek gains support for the mt6797 mobile-phone SoC platform
   and corresponding evaluation board.
 
 - Amlogic board support gets added for the NanoPi K2 and S905x
   LibreTech CC single-board computers and the R-Box Pro set-top-box
 
 - Allwinner board support gets added for the OrangePi Win,
   Orangepi Zero Plus 2, NanoPi NEO2 and Orange Pi Prime single
   board computers and the SoPine system-on-module.
 
 - Renesas board support for Salvator-XS and H3ULCB
   automotive development systems.
 
 - Socionext Uniphier board support for LD11-global and LD20-global,
   whatever those may be.
 
 - Broadcom adds support for the new Stingray communication processor
   in its iProc family, along with two reference boards.
 
 Other updates include:
 
 - For the hisicon platform, support for Hi3660-Hikey960 gets
   extended significantly.
 
 - Lots of smaller updates for Renesas, Amlogic, Rockchip, UniPhier,
   Broadcom, Allwinner, Hisilicon, Qualcomm, Marvell, and NXP.

Linus Torvalds f4dd029ee0 Char/Misc patches for 4.13-rc1
Here is the "big" char/misc driver patchset for 4.13-rc1.
 
 Lots of stuff in here, a large thunderbolt update, w1 driver header
 reorg, the new mux driver subsystem, google firmware driver updates, and
 a raft of other smaller things.  Full details in the shortlog.
 
 All of these have been in linux-next for a while with the only reported
 issue being a merge problem with this tree and the jc-docs tree in the
 w1 documentation area.  The fix should be obvious for what to do when it
 happens, if not, we can send a follow-up patch for it afterward.

Pull SMP hotplug updates from Thomas Gleixner:
 "This update is primarily a cleanup of the CPU hotplug locking code.

  The hotplug locking mechanism is an open coded RWSEM, which allows
  recursive locking. The main problem with that is the recursive nature
  as it evades the full lockdep coverage and hides potential deadlocks.

  The rework replaces the open coded RWSEM with a percpu RWSEM and
  establishes full lockdep coverage that way.

  The bulk of the changes fix up recursive locking issues and address
  the now fully reported potential deadlocks all over the place. Some of
  these deadlocks have been observed in the RT tree, but on mainline the
  probability was low enough to hide them away."

Lorenzo Pieralisi 769b461fc0 arm64: PCI: Drop DT IRQ allocation from pcibios_alloc_irq()
With the introduction of struct pci_host_bridge.map_irq pointer it is
possible to assign IRQs for all devices originating from a PCI host bridge
at probe time; this is implemented through pci_assign_irq() that relies on
the struct pci_host_bridge.map_irq pointer to map IRQ for a given device.

The benefits this brings are twofold:

  - the IRQ for a device is assigned once at probe time
  - the IRQ assignment works also for hotplugged devices

With all DT based PCI host bridges converted to the struct
pci_host_bridge.{map/swizzle}_irq hooks mechanism the DT IRQ allocation in
ARM64 pcibios_alloc_irq() is now redundant and can be removed.

Luc Van Oostenryck 425e1ed73e arm64: fix endianness annotation for 'struct jit_ctx' and friends
struct jit_ctx::image is used the store a pointer to the jitted
intructions, which are always little-endian. These instructions
are thus correctly converted from native order to little-endian
before being stored but the pointer 'image' is declared as for
native order values.

Fix this by declaring the field as __le32* instead of u32*.
Same for the pointer used in jit_fill_hole() to initialize
the image.

Dave Martin 5fbd5fc49f arm64: ptrace: Fix incorrect get_user() use in compat_vfp_set()
Now that compat_vfp_get() uses the regset API to copy the FPSCR
value out to userspace, compat_vfp_set() looks inconsistent.  In
particular, compat_vfp_set() will fail if called with kbuf != NULL
&& ubuf == NULL (which is valid usage according to the regset API).

This patch fixes compat_vfp_set() to use user_regset_copyin(),
similarly to compat_vfp_get().

This also squashes a sparse warning triggered by the cast that
drops __user when calling get_user().

Dave Martin 16d38acb12 arm64: ptrace: Remove redundant overrun check from compat_vfp_set()
compat_vfp_set() checks for userspace trying to write an excessive
amount of data to the regset.  However this check is conspicuous
for its absence from every other _set() in the arm64 ptrace
implementation.  In fact, the core ptrace_regset() already clamps
userspace's iov_len to the regset size before the individual regset
.{get,set}() methods get called.

This patch removes the redundant check.

If get_user() fails when reading the new FPSCR value from userspace

This patch prevents this by checking the return from get_user()

that's still not what userspace expects.

Luc Van Oostenryck 15ad6ace52 arm64: fix endianness annotation for __apply_alternatives()/get_alt_insn()
get_alt_insn() is used to read and create ARM instructions, which
are always stored in memory in little-endian order. These values
are thus correctly converted to/from native order when processed
but the pointers used to hold the address of these instructions
are declared as for native order values.

Fix this by declaring the pointers as __le32* instead of u32* and
make the few appropriate needed changes like removing the unneeded
cast '(u32*)' in front of __ALT_PTR()'s definition.

Luc Van Oostenryck f0cda7e6dc arm64: fix endianness annotation in acpi_parking_protocol.c
Here both variables 'cpu_id' and 'entry_point' are read via
read[lq]_relaxed(), from a little-endian annotated pointer
and then used as a native endian value.

This is correct since the read[lq]() family of function
internally do a little-to-native endian conversion.

But in this case, it is wrong to declare these variable as
little-endian since there are native ones.

Fix this by changing the declaration of these variables
as 'u32' or 'u64' instead of '__le32' / '__le64'.

Luc Van Oostenryck 57c138357d arm64: fix endianness annotation for aarch64_insn_write()
aarch64_insn_write() is used to write an instruction.
As on ARM64 in-memory instructions are always stored
in little-endian order, this function, taking the instruction
opcode in native order, correctly convert it to little-endian
before sending it to an helper function __aarch64_insn_write()
which will do the effective write.

This is all good, but the variable and argument holding the
converted value are not annotated for a little-endian value
but left for native values.

Fix this by adjusting the prototype of the helper and
directly using the result of cpu_to_le32() without passing
by an intermediate variable (which was not a distinct one
but the same as the one holding the native value).

The function arch64_insn_read() is used to read an instruction.
On AM64 instructions are always stored in little-endian order
and thus the function correctly do a little-to-native endian

However, the variable used to hold the value before the conversion

Fix this by using the correct type for the declaration: __le32

Note: This only works because the function reading the value,
      probe_kernel_read((), takes a void pointer and void pointers
      are endian-agnostic. Otherwise probe_kernel_read() should
      also be properly annotated (or worse, need to be specialized).

ARM64 depends on the macro __AARCH64EB__ being defined or not
to correctly select or define endian-specific macros, structures
or pieces of code.

This macro is predefined by the compiler but sparse knows nothing
about it and thus may pre-process files differently from what
gcc would.

Fix this by passing '-D__AARCH64EL__' or '-D__AARCH64EB__' to
sparse depending of the endianness of the kernel, like defined
by GCC.

Note: In most case it won't change anything since most arm64 use
      little-endian (but an allyesconfig would use big-endian!).

Mark Rutland 8486e54d30 arm64: ftrace: fix !CONFIG_ARM64_MODULE_PLTS kernels
When a kernel is built without CONFIG_ARM64_MODULE_PLTS, we don't
generate the expected branch instruction in ftrace_make_nop(). This
means we pass zero (rather than a valid branch) to ftrace_modify_code()
as the expected instruction to validate. This causes us to return
-EINVAL to the core ftrace code for a valid case, resulting in a splat
at boot time.

This was an unintended effect of commit:

  687644209a ("arm64: ftrace: fix building without CONFIG_MODULES")

... which incorrectly moved the generation of the branch instruction
into the ifdef for CONFIG_ARM64_MODULE_PLTS.

This patch fixes the issue by moving the ifdef inside of the relevant
if-else case, and always checking that the branch is in range,
regardless of CONFIG_ARM64_MODULE_PLTS. This ensures that we generate
the expected branch instruction, and also improves our sanity checks.

For consistency, both ftrace_make_nop() and ftrace_make_call() are
updated with this pattern.

This patch defines an extra_context signal frame record that can be
used to describe an expanded signal frame, and modifies the context
block allocator and signal frame setup and parsing code to create,
populate, parse and decode this block as necessary.

To avoid abuse by userspace, parse_user_sigframe() attempts to
ensure that:

 * no more than one extra_context is accepted;
 * the extra context data is a sensible size, and properly placed
   and aligned.

The extra_context data is required to start at the first 16-byte
aligned address immediately after the dummy terminator record
following extra_context in rt_sigframe.__reserved[] (as ensured
during signal delivery).  This serves as a sanity-check that the
signal frame has not been moved or copied without taking the extra
data into account.

As I found by chance while merging another patch, the usage of
a dma-mask in this DT node is wrong for multiple reasons:

- dma-masks are a Linux specific concept, not a general
  hardware feature
- In DT, we use the "dma-ranges" property to describe how DMA
  addresses related between devices.
- The 40-bit mask appears to be completely unnecessary here, as
  the SoC cannot address that much memory anyway, so simply
  asking for a 64-bit mask (as supported by the device) should
  succeed anyway.

The patch to remove the parsing of the property is getting merged
through the crypto tree.

Currently external aborts are unsupported by the guest abort
handling. Add handling for SEAs so that the host kernel reports
SEAs which occur in the guest kernel.

When an SEA occurs in the guest kernel, the guest exits and is
routed to kvm_handle_guest_abort(). Prior to this patch, a print
message of an unsupported FSC would be printed and nothing else
would happen. With this patch, the code gets routed to the APEI
handling of SEAs in the host kernel to report the SEA information.

ARM APEI extension proposal added SEA (Synchronous External Abort)
notification type for ARMv8.
Add a new GHES error source handling function for SEA. If an error
source's notification type is SEA, then this function can be registered
into the SEA exception handler. That way GHES will parse and report
SEA exceptions when they occur.
An SEA can interrupt code that had interrupts masked and is treated as
an NMI. To aid this the page of address space for mapping APEI buffers
while in_nmi() is always reserved, and ghes_ioremap_pfn_nmi() is
changed to use the helper methods to find the prot_t to map with in
the same way as ghes_ioremap_pfn_irq().

Mark Rutland 8effeaaf2c arm64: dump cpu_hwcaps at panic time
When debugging a kernel panic(), it can be useful to know which CPU
features have been detected by the kernel, as some code paths can depend
on these (and may have been patched at runtime).

This patch adds a notifier to dump the detected CPU caps (as a hex
string) at panic(), when we log other information useful for debugging.
On a Juno R1 system running v4.12-rc5, this looks like:

[  615.431249] Kernel panic - not syncing: Fatal exception in interrupt
[  615.437609] SMP: stopping secondary CPUs
[  615.441872] Kernel Offset: disabled
[  615.445372] CPU features: 0x02086
[  615.448522] Memory Limit: none

A developer can decode this by looking at the corresponding
<asm/cpucaps.h> bits. For example, the above decodes as:

* bit  1: ARM64_WORKAROUND_DEVICE_LOAD_ACQUIRE
* bit  2: ARM64_WORKAROUND_845719
* bit  7: ARM64_WORKAROUND_834220

Dave Martin 936eb65ca2 arm64: ptrace: Flush user-RW TLS reg to thread_struct before reading
When reading current's user-writable TLS register (which occurs
when dumping core for native tasks), it is possible that userspace
has modified it since the time the task was last scheduled out.
The new TLS register value is not guaranteed to have been written
immediately back to thread_struct in this case.

As a result, a coredump can capture stale data for this register.
Reading the register for a stopped task via ptrace is unaffected.

For native tasks, this patch explicitly flushes the TPIDR_EL0
register back to thread_struct before dumping when operating on
current, thus ensuring that coredump contents are up to date.  For
compat tasks, the TLS register is not user-writable and so cannot
be out of sync, so no flush is required in compat_tls_get().

Dave Martin af66b2d88a arm64: ptrace: Fix VFP register dumping in compat coredumps
Currently, VFP registers are omitted from coredumps for compat
processes, due to a bug in the REGSET_COMPAT_VFP regset
implementation.

compat_vfp_get() needs to transfer non-contiguous data from
thread_struct.fpsimd_state, and uses put_user() to handle the
offending trailing word (FPSCR).  This fails when copying to a
kernel address (i.e., kbuf && !ubuf), which is what happens when
dumping core.  As a result, the ELF coredump core code silently
omits the NT_ARM_VFP note from the dump.

It would be possible to work around this with additional special
case code for the put_user(), but since user_regset_copyout() is
explicitly designed to handle this scenario it is cleaner to port
the put_user() to a user_regset_copyout() call, which this patch
does.

When using sparse on the arm64 tree we get many thousands of
warnings like 'constant ... is so big it is unsigned long long'
or 'shift too big (32) for type unsigned long'. This happens
because by default sparse considers the machine as 32bit and
defines the size of the types accordingly.

Fix this by passing the '-m64' flag to sparse so that
sparse can correctly define longs as being 64bit.

Enable gpio support for CP and AP on the Marvell Armada 7K/8K SoCs.

The Armada 8K has two CP110 blocks, each having two GPIO controllers.
However, in each CP110 block, one of the GPIO controller cannot be
used: in the master CP110, only the second GPIO controller can be used,
while on the slave CP110, only the first GPIO controller can be used.

On the other side, the Armada 7K has only one CP110, but both its GPIO
controllers can be used.

For this reason, the GPIO controllers are marked as "disabled" in the
armada-cp110-master.dtsi and armada-cp110-slave.dtsi files, and only
enabled in the per-SoC dtsi files.

Dave Martin bb4322f743 arm64: signal: factor out signal frame record allocation
This patch factors out the allocator for signal frame optional
records into a separate function, to ensure consistency and
facilitate later expansion.

No overrun checking is currently done, because the allocation is in
user memory and anyway the kernel never tries to allocate enough
space in the signal frame yet for an overrun to occur.  This
behaviour will be refined in future patches.

The approach taken in this patch to allocation of the terminator
record is not very clean: this will also be replaced in subsequent
patches.

For future extension, a comment is added in sigcontext.h
documenting the current static allocations in __reserved[].  This
will be important for determining under what circumstances
userspace may or may not see an expanded signal frame.

In preparation for expanding the signal frame, this patch refactors
the signal frame setup code in setup_sigframe() into two separate
passes.

The first pass, setup_sigframe_layout(), determines the size of the
signal frame and its internal layout, including the presence and
location of optional records.  The resulting knowledge is used to
allocate and locate the user stack space required for the signal
frame and to determine which optional records to include.

The second pass, setup_sigframe(), is called once the stack frame
is allocated in order to populate it with the necessary context
information.

As a result of these changes, it becomes more natural to represent
locations in the signal frame by a base pointer and an offset,
since the absolute address of each location is not known during the
layout pass.  To be more consistent with this logic,
parse_user_sigframe() is refactored to describe signal frame
locations in a similar way.

This change has no effect on the signal ABI, but will make it
easier to expand the signal frame in future patches.

Dave Martin 47ccb02868 arm64: signal: Refactor sigcontext parsing in rt_sigreturn
Currently, rt_sigreturn does very limited checking on the
sigcontext coming from userspace.

Future additions to the sigcontext data will increase the potential
for surprises.  Also, it is not clear whether the sigcontext
extension records are supposed to occur in a particular order.

To allow the parsing code to be extended more easily, this patch
factors out the sigcontext parsing into a separate function, and
adds extra checks to validate the well-formedness of the sigcontext
structure.

Dave Martin 20987de3c2 arm64: signal: split frame link record from sigcontext structure
In order to be able to increase the amount of the data currently
written to the __reserved[] array in the signal frame, it is
necessary to overwrite the locations currently occupied by the
{fp,lr} frame link record pushed at the top of the signal stack.

In order for this to work, this patch detaches the frame link
record from struct rt_sigframe and places it separately at the top
of the signal stack.  This will allow subsequent patches to insert
data between it and __reserved[].

This change relies on the non-ABI status of the placement of the
frame record with respect to struct sigframe: this status is
undocumented, but the placement is not declared or described in the
user headers, and known unwinder implementations (libgcc,
libunwind, gdb) appear not to rely on it.

To avoid issues with the /proc/kcore code getting confused about the
kernels block mappings in the VMALLOC region, enable the existing
facility that describes the [_text, _end) interval as a separate
KCORE_TEXT region, which supersedes the KCORE_VMALLOC region that
it intersects with on arm64.

Will Deacon dbb236c1ce arm64/vdso: Fix nsec handling for CLOCK_MONOTONIC_RAW
Recently vDSO support for CLOCK_MONOTONIC_RAW was added in
49eea433b3 ("arm64: Add support for CLOCK_MONOTONIC_RAW in
clock_gettime() vDSO"). Noticing that the core timekeeping code
never set tkr_raw.xtime_nsec, the vDSO implementation didn't
bother exposing it via the data page and instead took the
unshifted tk->raw_time.tv_nsec value which was then immediately
shifted left in the vDSO code.

Unfortunately, by accellerating the MONOTONIC_RAW clockid, it
uncovered potential 1ns time inconsistencies caused by the
timekeeping core not handing sub-ns resolution.

Now that the core code has been fixed and is actually setting
tkr_raw.xtime_nsec, we need to take that into account in the
vDSO by adding it to the shifted raw_time value, in order to
fix the user-visible inconsistency. Rather than do that at each
use (and expand the data page in the process), instead perform
the shift/addition operation when populating the data page and
remove the shift from the vDSO code entirely.

[jstultz: minor whitespace tweak, tried to improve commit
 message to make it more clear this fixes a regression]
