Pull arch/sh syscall table scripting from Arnd Bergmann:
"I worked with Firoz Khan to change all architectures to have their
system call tables (syscall.S and asm/unistd.h) generated by a script
from a more readable input file the same way that we already had on
x86, s390 and arm.
I offered to take those conversions through the asm-generic tree that
did not get picked up by the architecture maintainers, and fortunately
all but one have now been accepted into arch maintainer trees, so this
branch only contains the conversion for arch/sh/, with permission from
Rich.
The conversion does not include the old 64-bit sh5 architecture, which
has never shipped and not even compiled in a long time. The table in
include/uapi/asm/unistd.h is also not included here, as Firoz is still
working on that one, it will have to wait for the next following merge
window, hopefully together with the addition of the 64-bit time_t
system calls for the y2038 work that led to the system call table
rework"

Pull arm64 festive updates from Will Deacon:
"In the end, we ended up with quite a lot more than I expected:
- Support for ARMv8.3 Pointer Authentication in userspace (CRIU and
kernel-side support to come later)
- Support for per-thread stack canaries, pending an update to GCC
that is currently undergoing review
- Support for kexec_file_load(), which permits secure boot of a kexec
payload but also happens to improve the performance of kexec
dramatically because we can avoid the sucky purgatory code from
userspace. Kdump will come later (requires updates to libfdt).
- Optimisation of our dynamic CPU feature framework, so that all
detected features are enabled via a single stop_machine()
invocation
- KPTI whitelisting of Cortex-A CPUs unaffected by Meltdown, so that
they can benefit from global TLB entries when KASLR is not in use
- 52-bit virtual addressing for userspace (kernel remains 48-bit)
- Patch in LSE atomics for per-cpu atomic operations
- Custom preempt.h implementation to avoid unconditional calls to
preempt_schedule() from preempt_enable()
- Support for the new 'SB' Speculation Barrier instruction
- Vectorised implementation of XOR checksumming and CRC32
optimisations
- Workaround for Cortex-A76 erratum #1165522
- Improved compatibility with Clang/LLD
- Support for TX2 system PMUS for profiling the L3 cache and DMC
- Reflect read-only permissions in the linear map by default
- Ensure MMIO reads are ordered with subsequent calls to Xdelay()
- Initial support for memory hotplug
- Tweak the threshold when we invalidate the TLB by-ASID, so that
mremap() performance is improved for ranges spanning multiple PMDs.
- Minor refactoring and cleanups"

Testing has shown, that when using mainline U-Boot on MT7688 based
boards, the system may hang or crash while mounting the root-fs. The
main issue here is that mainline U-Boot configures EBase to a value
near the end of system memory. And with CONFIG_CPU_MIPSR2_IRQ_VI
disabled, trap_init() will not allocate a new area to place the
exception handler. The original value will be used and the handler
will be copied to this location, which might already be used by some
userspace application.
The MT7688 supports VI - its config3 register is 0x00002420, so VInt
(Bit 5) is set. But without setting CONFIG_CPU_MIPSR2_IRQ_VI this
bit will not be evaluated to result in "cpu_has_vi" being set. This
patch now selects CONFIG_CPU_MIPSR2_IRQ_VI on MT7620/8 which results
trap_init() to allocate some memory for the exception handler.
Please note that this issue was not seen with the Mediatek U-Boot
version, as it does not touch EBase (stays at default of 0x8000.0000).
This is strictly also not correct as the kernel (_text) resides
here.

Passing atomic=true to skcipher_walk_virt() only makes the later
skcipher_walk_done() calls use atomic memory allocations, not
skcipher_walk_virt() itself. Thus, we have to move it outside of the
preemption-disabled region (kernel_fpu_begin()/kernel_fpu_end()).
(skcipher_walk_virt() only allocates memory for certain layouts of the
input scatterlist, hence why I didn't notice this earlier...)

Add the appropriate scatter/gather stubs to the avx asm.
In the C code, we can now always use crypt_by_sg, since both
sse and asm code now support scatter/gather.
Introduce a new struct, aesni_gcm_tfm, that is initialized on
startup to point to either the SSE, AVX, or AVX2 versions of the
four necessary encryption/decryption routines.
GENX_OPTSIZE is still checked at the start of crypt_by_sg. The
total size of the data is checked, since the additional overhead
is in the init function, calculating additional HashKeys.

Add support for 192/256-bit keys using the avx gcm/aes routines.
The sse routines were previously updated in e31ac32d3b (Add support
for 192 & 256 bit keys to AESNI RFC4106).
Instead of adding an additional loop in the hotpath as in e31ac32d3b,
this diff instead generates separate versions of the code using macros,
and the entry routines choose which version once. This results
in a 5% performance improvement vs. adding a loop to the hot path.
This is the same strategy chosen by the intel isa-l_crypto library.
The key size checks are removed from the c code where appropriate.
Note that this diff depends on using gcm_context_data - 256 bit keys
require 16 HashKeys + 15 expanded keys, which is larger than
struct crypto_aes_ctx, so they are stored in struct gcm_context_data.

Add the gcm_context_data structure to the avx asm routines.
This will be necessary to support both 256 bit keys and

The pre-computed HashKeys are now stored in the gcm_context_data
struct, which is expanded to hold the greater number of hashkeys
necessary for avx.
Loads and stores to the new struct are always done unlaligned to
avoid compiler issues, see e5b954e8 "Use unaligned loads from

The GCM_ENC_DEC routines for AVX and AVX2 are identical, except they
call separate sub-macros. Pass the macros as arguments, and merge them.
This facilitates additional refactoring, by requiring changes in only
one place.
The GCM_ENC_DEC macro was moved above the CONFIG_AS_AVX* ifdefs,
since it will be used by both AVX and AVX2.

and EFI_MIXED_MODE
The following commit:
d5052a7130a6 ("x86/efi: Unmap EFI boot services code/data regions from efi_pgd")
forgets to take two EFI modes into consideration, namely EFI_OLD_MEMMAP and
EFI_MIXED_MODE:
- EFI_OLD_MEMMAP is a legacy way of mapping EFI regions into swapper_pg_dir
using ioremap() and init_memory_mapping(). This feature can be enabled by
passing "efi=old_map" as kernel command line argument. But,
efi_unmap_pages() unmaps EFI boot services code/data regions *only* from
efi_pgd and hence cannot be used for unmapping EFI boot services code/data
regions from swapper_pg_dir.
Introduce a temporary fix to not unmap EFI boot services code/data regions
when EFI_OLD_MEMMAP is enabled while working on a real fix.
- EFI_MIXED_MODE is another feature where a 64-bit kernel runs on a
64-bit platform crippled by a 32-bit firmware. To support EFI_MIXED_MODE,
all RAM (i.e. namely EFI regions like EFI_CONVENTIONAL_MEMORY,
EFI_LOADER_<CODE/DATA>, EFI_BOOT_SERVICES_<CODE/DATA> and
EFI_RUNTIME_CODE/DATA regions) is mapped into efi_pgd all the time to
facilitate EFI runtime calls access it's arguments in 1:1 mode.
Hence, don't unmap EFI boot services code/data regions when booted in mixed mode.
