Commit 0515e5999a ("bpf: introduce BPF_PROG_TYPE_PERF_EVENT
program type") introduced the bpf_perf_event_data structure which
exports the pt_regs structure. This is OK for multiple architectures
but fail for s390 and arm64 which do not export pt_regs. Programs
using them, for example, the bpf selftest fail to compile on these
architectures.
For s390, exporting the pt_regs is not an option because s390 wants
to allow changes to it. For arm64, there is a user_pt_regs structure
that covers parts of the pt_regs structure for use by user space.
To solve the broken uapi for s390 and arm64, introduce an abstract
type for pt_regs and add an asm/bpf_perf_event.h file that concretes
the type. An asm-generic header file covers the architectures that
export pt_regs today.
The arch-specific enablement for s390 and arm64 follows in separate
commits.

Add a custom serial.h header for MIPS, allowing platforms to override
the asm-generic version if required.
The generic platform uses this header to set BASE_BAUD to 0. The
generic platform supports multiple boards, which may have different
UART clocks. Also one of the boards supported is the Boston FPGA board,
where the UART clock depends on the loaded FPGA bitfile. As such there
is no way that the generic kernel can set a compile time default
BASE_BAUD.
Commit 31cb9a8575 ("earlycon: initialise baud field of earlycon device
structure") changed the behavior of of_setup_earlycon such that any baud
rate set in the device tree is now set in the earlycon structure. The
UART driver will then calculate a divisor based on BASE_BAUD and set it.
With MIPS generic kernels this resulted in garbage output due to the
incorrect uart clock rate being used to calculate a divisor. This
commit, combined with "serial: 8250_early: Only set divisor if valid clk
& baud" prevents the earlycon code setting a bad divisor and restores
earlycon output.

Pull libnvdimm and dax updates from Dan Williams:
"Save for a few late fixes, all of these commits have shipped in -next
releases since before the merge window opened, and 0day has given a
build success notification.
The ext4 touches came from Jan, and the xfs touches have Darrick's
reviewed-by. An xfstest for the MAP_SYNC feature has been through
a few round of reviews and is on track to be merged.
- Introduce MAP_SYNC and MAP_SHARED_VALIDATE, a mechanism to enable
'userspace flush' of persistent memory updates via filesystem-dax
mappings. It arranges for any filesystem metadata updates that may
be required to satisfy a write fault to also be flushed ("on disk")
before the kernel returns to userspace from the fault handler.
Effectively every write-fault that dirties metadata completes an
fsync() before returning from the fault handler. The new
MAP_SHARED_VALIDATE mapping type guarantees that the MAP_SYNC flag
is validated as supported by the filesystem's ->mmap() file
operation.
- Add support for the standard ACPI 6.2 label access methods that
replace the NVDIMM_FAMILY_INTEL (vendor specific) label methods.
This enables interoperability with environments that only implement
the standardized methods.
- Add support for the ACPI 6.2 NVDIMM media error injection methods.
- Add support for the NVDIMM_FAMILY_INTEL v1.6 DIMM commands for
latch last shutdown status, firmware update, SMART error injection,
and SMART alarm threshold control.
- Cleanup physical address information disclosures to be root-only.
- Fix revalidation of the DIMM "locked label area" status to support
dynamic unlock of the label area.
- Expand unit test infrastructure to mock the ACPI 6.2 Translate SPA
(system-physical-address) command and error injection commands.

Building 32-bit MIPS64r2 kernels produces warnings like the following
on certain toolchains (such as GNU assembler 2.24.90, but not GNU
assembler 2.28.51) since commit 22b8ba765a ("MIPS: Fix MIPS64 FP
save/restore on 32-bit kernels"), due to the exposure of fpu_save_16odd
from fpu_save_double and fpu_restore_16odd from fpu_restore_double:
arch/mips/kernel/r4k_fpu.S:47: Warning: float register should be even, was 1
...
arch/mips/kernel/r4k_fpu.S:59: Warning: float register should be even, was 1
...
This appears to be because .set mips64r2 does not change the FPU ABI to
64-bit when -march=mips64r2 (or e.g. -march=xlp) is provided on the
command line on that toolchain, from the default FPU ABI of 32-bit due
to the -mabi=32. This makes access to the odd FPU registers invalid.
Fix by explicitly changing the FPU ABI with .set fp=64 directives in
fpu_save_16odd and fpu_restore_16odd, and moving the undefine of fp up
in asmmacro.h so fp doesn't turn into $30.

Patchwork: https://patchwork.linux-mips.org/patch/17656/
Update the thread_info::syscall field when registers are modified via
ptrace to change or cancel the system call being entered.
This is important to allow seccomp and the syscall entry and exit trace
events to observe the new syscall number changed by the normal ptrace
hook or seccomp. That includes allowing seccomp's recheck of the system
call number after SECCOMP_RET_TRACE to notice if the syscall is changed
to a denied one, which happens in seccomp since commit ce6526e8af
("seccomp: recheck the syscall after RET_TRACE") in v4.8.
In the process of doing this, the logic to determine whether an indirect
system call is in progress (i.e. the O32 ABI's syscall()) is abstracted
into mips_syscall_is_indirect(), and a new mips_syscall_update_nr() is
used to update the thread_info::syscall based on the register state.
The following ptrace operations are updated:
- PTRACE_SETREGS (ptrace_setregs()).
- PTRACE_SETREGSET with NT_PRSTATUS (gpr32_set() and gpr64_set()).
- PTRACE_POKEUSR with 2/v0 or 4/a0 for indirect syscall
([compat_]arch_ptrace()).

Patchwork: https://patchwork.linux-mips.org/patch/16995/
32-bit kernels can be configured to support MIPS64, in which case
neither CONFIG_64BIT or CONFIG_CPU_MIPS32_R* will be set. This causes
the CP0_Status.FR checks at the point of floating point register save
and restore to be compiled out, which results in odd FP registers not
being saved or restored to the task or signal context even when
CP0_Status.FR is set.
Fix the ifdefs to use CONFIG_CPU_MIPSR2 and CONFIG_CPU_MIPSR6, which are
enabled for the relevant revisions of either MIPS32 or MIPS64, along
with some other CPUs such as Octeon (r2), Loongson1 (r2), XLP (r2),
Loongson 3A R2.
The suspect code originates from commit 597ce1723e ("MIPS: Support for
64-bit FP with O32 binaries") in v3.14, however the code in
__enable_fpu() was consistent and refused to set FR=1, falling back to
software FPU emulation. This was suboptimal but should be functionally
correct.
Commit fcc53b5f6c ("MIPS: fpu.h: Allow 64-bit FPU on a 64-bit MIPS R6
CPU") in v4.2 (and stable tagged back to 4.0) later introduced the bug
by updating __enable_fpu() to set FR=1 but failing to update the other
similar ifdefs to enable FR=1 state handling.
