Looking at generated code for handle_signal32() shows calls to a
function called __unsafe_save_user_regs.constprop.0 while user access
is open.

And that __unsafe_save_user_regs.constprop.0 function has two nops at
the begining, allowing it to be traced, which is unexpected during
user access open window.

The solution could be to mark __unsafe_save_user_regs() no trace, but
to be on the safe side the most efficient is to flag it __always_inline
as already done for function __unsafe_restore_general_regs(). The
function is relatively small and only called twice, so the size
increase will remain in the noise.

Do the same with save_tm_user_regs_unsafe() as it may suffer the
same issue.

kallsyms_lookup() which in turn calls kallsyms_lookup_buildid() writes

Thus the array passed as namebuf to kallsyms_lookup() should be

In xmon.c the array was defined to be "128" bytes directly, without
using KSYM_NAME_LEN. Commit b8a94bfb ("kallsyms: increase maximum

The recently added P10 AES/GCM code added some files containing
CRYPTOGAMS perl-asm code which are near duplicates of the p8 files
found in drivers/crypto/vmx.

In particular the newly added files produce functions with identical
names to the existing code.

When the kernel is built with CONFIG_CRYPTO_AES_GCM_P10=y and
CONFIG_CRYPTO_DEV_VMX_ENCRYPT=y that leads to link errors, eg:

Commit 1e8fed87 ("powerpc: drop ranges for definition of
ARCH_FORCE_MAX_ORDER") removed the limits on the possible values for
ARCH_FORCE_MAX_ORDER.

However removing the ranges entirely causes some common work flows to
break. For example building a defconfig (which uses 64K pages), changing
the page size to 4K, and rebuilding used to work, because
ARCH_FORCE_MAX_ORDER would be clamped to 12 by the ranges.

With the ranges removed it creates a kernel that builds but crashes at
boot:
  kernel BUG at mm/huge_memory.c:470!
  Oops: Exception in kernel mode, sig: 5 [#1]
  ...
  NIP hugepage_init+0x9c/0x278

    kernel_init+0x30/0x1a0
    ret_from_kernel_user_thread+0x14/0x1c

The reasoning for removing the ranges was that some of the values were
too large. So take that into account and limit the maximums to 10 which
is the default max, except for the 4K case which uses 12.
