The powerpc kernel can be built to have either a 4K PAGE_SIZE or a 64K
PAGE_SIZE.
However when built with a 4K PAGE_SIZE there is an additional config
option which can be enabled, PPC_HAS_HASH_64K, which means the kernel
also knows how to hash a 64K page even though the base PAGE_SIZE is 4K.

syscall_get_error() is unused, and never has been.
It's also probably wrong, as it negates r3 before returning it, but that
depends on what the caller is expecting.
It also doesn't deal with compat, and doesn't deal with TIF_NOERROR.
Although we could fix those, until it has a caller and it's
Currently the only caller of syscall_set_return_value() is seccomp

This means we have not noticed that our implementation of
syscall_set_return_value() negates error, even though the value passed
in is already negative.
So remove the negation in
Currently syscall_get_arguments() has two loops, one for compat and one

Currently syscall_get_arguments() is used by syscall tracepoints, and
collect_syscall() which is used in some debugging as well as
/proc/pid/syscall.
The current implementation just copies regs-gpr[3 .. 5] out, which is
fine for all the current use cases.
When we enable seccomp filter, that will
The documentation for syscall_get_nr() in asm-generic says:
Note this returns int even on 64-bit machines. Only 32 bits of

is 64 bits, this truncates to 32 bits so 0x means -1.
However our implementation was never updated
SIG_SYS was added in commit a0727e8ce513 signal, x86: add SIGSYS info

Because we use the asm-generic struct siginfo, we got support for

However there was no compat handling added for powerpc. That means we've

This commit enables seccomp filter on powerpc, now that we have all the
