9257959a6e ("locking/atomic: scripts: restructure fallback ifdeffery")
The ordering fallbacks for atomic*_read_acquire() and
atomic*_set_release() erroneously fall back to the implictly relaxed
atomic*_read() and atomic*_set() variants respectively, without any
additional barriers. This loses the ACQUIRE and RELEASE ordering
semantics, which can result in a wide variety of problems, even on
strongly-ordered architectures where the implementation of
atomic*_read() and/or atomic*_set() allows the compiler to reorder those
relative to other accesses.
In practice this has been observed to break bit spinlocks on arm64,
resulting in dentry cache corruption.
The fallback logic was intended to allow ACQUIRE/RELEASE/RELAXED ops to
be defined in terms of FULL ops, but where an op had RELAXED ordering by
default, this unintentionally permitted the ACQUIRE/RELEASE ops to be
defined in terms of the implicitly RELAXED default.
This patch corrects the logic to avoid falling back to implicitly
RELAXED ops, resulting in the same behaviour as prior to commit
9257959a6e.
I've verified the resulting assembly on arm64 by generating outlined
wrappers of the atomics. Prior to this patch the compiler generates
sequences using relaxed load (LDR) and store (STR) instructions, e.g.
| <outlined_atomic64_read_acquire>:
| ldr x0, [x0]
| ret
|
| <outlined_atomic64_set_release>:
| str x1, [x0]
| ret
With this patch applied the compiler generates sequences using the
intended load-acquire (LDAR) and store-release (STLR) instructions, e.g.
| <outlined_atomic64_read_acquire>:
| ldar x0, [x0]
| ret
|
| <outlined_atomic64_set_release>:
| stlr x1, [x0]
| ret
To make sure that there were no other victims of the ifdeffery rewrite,
I generated outlined copies of all of the {atomic,atomic64,atomic_long}
atomic operations before and after commit 9257959a6e. A diff of
the generated assembly on arm64 shows that only the read_acquire() and
set_release() operations were changed, and only lost their intended
ordering:

csky, i386, m68k, microblaze, mips, nios2, openrisc, powerpc, riscv,
s390, sh, sparc, x86_64, and xtensa, for which I've seen no issues. I
was unable to build test for ia64 and parisc due to existing build

The arch_calc_vm_prot_bits() macro uses VM_PKEY_BIT0 etc. which are
not part of the UAPI, so the macro is completely useless for userspace.
It is also hidden behind the CONFIG_X86_INTEL_MEMORY_PROTECTION_KEYS
config switch which we shouldn't expose to userspace. Thus let's move
this macro into a new internal header instead.

This is especially useful for continuous kernel uprevs when
some symbols can be either removed or renamed between kernel

By default KCONFIG_WARN_UNKNOWN_SYMBOLS generates warnings,
which are non-terminal. There is an additional environment

.llvm.call-graph-profile section is added by clang when the kernel is
built with profiles (e.g. -fprofile-sample-use= or -fprofile-use=).
Note that .llvm.call-graph-profile intentionally uses REL relocations
to decrease the object size, for more details see
https://reviews.llvm.org/D104080.
The section contains edge information derived from text sections,
so .llvm.call-graph-profile itself doesn't need more analysis as
the text sections have been analyzed.
This change fixes the kernel build with clang and a sample profile
which currently fails with:

Commit d890f510c8 ("MODSIGN: Add modules_sign make target") introduced

Some time later, commit d9d8d7ed49 ("MODSIGN: Add option to not sign
modules during modules_install") introduced CONFIG_MODULE_SIG_ALL.
If it was disabled, mod_sign_cmd was set to no-op ('true' command).
It affected not only 'make modules_install' but also 'make modules_sign'.
With CONFIG_MODULE_SIG_ALL=n, neither modules_install nor modules_sign
is able to sign modules.
Kbuild has kept that behavior, and nobody has complained about it, but
I think it is weird.
CONFIG_MODULE_SIG_ALL=n should turn off signing only for modules_install.
If users want to sign modules manually, modules_sign should be offered.

This patch resolves these SyntaxWarnings by converting the relevant string
