Commit 784e0300fe ("rseq: Avoid infinite recursion when delivering
SIGSEGV") added a new ksig argument to the rseq_signal_deliver() &
rseq_handle_notify_resume() functions, and was merged in v4.18-rc2.
Meanwhile MIPS support for restartable sequences was also merged in
v4.18-rc2 with commit 9ea141ad54 ("MIPS: Add support for restartable
sequences"), and therefore didn't get updated for the API change.
This results in build failures like the following:
CC arch/mips/kernel/signal.o

Commit 5ec6486daa ("iio:imu: inv_mpu6050: support more interrupt types")
causes inv_mpu_core_probe() to fail if the IRQ does not have a
trigger-type setup.
This happens on machines where the mpu6050 is enumerated through ACPI and
an older Interrupt type ACPI resource is used for the interrupt, rather
then a GpioInt type type, causing the mpu6050 driver to no longer work
there. This happens on e.g. the Asus T100TA.
This commits makes the mpu6050 fallback to the old IRQF_TRIGGER_RISING
default if the irq-type is not setup, fixing this.

The following commit:
2c3625cb9f ("efi/x86: Fold __setup_efi_pci32() and __setup_efi_pci64() into one function")
... merged the two versions of __setup_efi_pciXX(), without taking into
account that the 32-bit version used a rather dodgy trick to pass an
immediate 0 constant as argument for a uint64_t parameter.
The issue is caused by the fact that on x86, UEFI protocol method calls
are redirected via struct efi_config::call(), which is a variadic function,
and so the compiler has to infer the types of the parameters from the
arguments rather than from the prototype.
As the 32-bit x86 calling convention passes arguments via the stack,
passing the unqualified constant 0 twice is the same as passing 0ULL,
which is why the 32-bit code in __setup_efi_pci32() contained the
following call:
status = efi_early->call(pci->attributes, pci,
EfiPciIoAttributeOperationGet, 0, 0,
&attributes);
to invoke this UEFI protocol method:
typedef
EFI_STATUS
(EFIAPI *EFI_PCI_IO_PROTOCOL_ATTRIBUTES) (
IN EFI_PCI_IO_PROTOCOL *This,
IN EFI_PCI_IO_PROTOCOL_ATTRIBUTE_OPERATION Operation,
IN UINT64 Attributes,
OUT UINT64 *Result OPTIONAL
);
After the merge, we inadvertently ended up with this version for both
32-bit and 64-bit builds, breaking the latter.
So replace the two zeroes with the explicitly typed constant 0ULL,
which works as expected on both 32-bit and 64-bit builds.
Wilfried tested the 64-bit build, and I checked the generated assembly
of a 32-bit build with and without this patch, and they are identical.

- Set the correct assembler machine type on e500mc, needed since binutils 2.26
introduced two forms for the "wait" instruction.
- A fix for potential missed TLB flushes with MADV_[FREE|DONTNEED] etc. and THP
on Power9 Radix.
- Three fixes to try and make our panic handling more robust by hard disabling
interrupts, and not marking stopped CPUs as offline because they haven't been
properly offlined.
- Three other minor fixes.

- clear buffers allocated with FORCE_CONTIGUOUS explicitly until the
CMA code honours __GFP_ZERO
- notrace annotation for secondary_start_kernel()
- use early_param() instead of __setup() for "kpti=" as it is needed
for the cpufeature callback remapping swapper to non-global mappings
- ensure writes to swapper are ordered wrt subsequent cache maintenance
in the kpti non-global remapping code

- Lazy FPSIMD switching fixes

Merge tag 'for-linus-4.18-rc2-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/xen/tip
Pull xen fixes from Juergen Gross:
"This contains the following fixes/cleanups:
- the removal of a BUG_ON() which wasn't necessary and which could
trigger now due to a recent change
- a correction of a long standing bug happening very rarely in Xen
dom0 when a hypercall buffer from user land was not accessible by
the hypervisor for very short periods of time due to e.g. page
migration or compaction
- usage of EXPORT_SYMBOL_GPL() instead of EXPORT_SYMBOL() in a
Xen-related driver (no breakage possible as using those symbols
without others already exported via EXPORT-SYMBOL_GPL() wouldn't
make any sense)
- a simplification for Xen PVH or Xen ARM guests
- some additional error handling for callers of xenbus_printf()"

early_identify_cpu() has to use early version of pgtable_l5_enabled()
that doesn't rely on cpu_feature_enabled().
Defining USE_EARLY_PGTABLE_L5 before all includes does the trick.
I lost the define in one of reworks of the original patch.

This reverts commit e4e961e36f.
We need to use early version of pgtable_l5_enabled() in
early_identify_cpu() as this code runs before cpu_feature_enabled() is
usable.
But it leads to section mismatch:
cpu_init()
load_mm_ldt()
ldt_slot_va()
LDT_BASE_ADDR
LDT_PGD_ENTRY
pgtable_l5_enabled()
__pgtable_l5_enabled
__pgtable_l5_enabled marked as __initdata, but cpu_init() is not __init.
It's fixable: early code can be isolated into a separate translation unit,
but such change collides with other work in the area. That's too much
hassle to save 4 bytes of memory.
Return __pgtable_l5_enabled back to be __ro_after_init.

Wire up io_pgetevents system call on powerpc.
io_pgetevents is a new syscall to read asynchronous I/O events from the
completion queue.
Tested with libaio branch aio-poll[1] and the io_pgetevents test (#22) passed
on both ppc64 LE and BE modes.

The ETF input should be connected to the funnel output, and the ETF
output should be connected to the replicator input. The labels are wrong
and these got swapped:

Access to UART0 is disabled by bootloaders. By leaving it enabled by
default would reboot the board.
Disable this for now, this would alteast give a board which boots.

In update_vf():
cftree_remove(cl);
update_cfmin(cl->cl_parent);
the cl_cfmin of cl->cl_parent is intentionally updated to 0
when that parent only has one child. And if this parent is
root qdisc, we could end up, in hfsc_schedule_watchdog(),
that we can't decide the next schedule time for qdisc watchdog.
But it seems safe that we can just skip it, as this watchdog is
not always scheduled anyway.
Thanks to Marco for testing all the cases, nothing is broken.
