powerpc: Adjust adding stack protector flags to KBUILD_CLAGS for clang

commit bee08a9e6ab03caf14481d97b35a258400ffab8f upstream.

After fixing the HAVE_STACKPROTECTER checks for clang's in-progress
per-task stack protector support [1], the build fails during prepare0
because '-mstack-protector-guard-offset' has not been added to
KBUILD_CFLAGS yet but the other '-mstack-protector-guard' flags have.

clang: error: '-mstack-protector-guard=tls' is used without '-mstack-protector-guard-offset', and there is no default
clang: error: '-mstack-protector-guard=tls' is used without '-mstack-protector-guard-offset', and there is no default
make[4]: *** [scripts/Makefile.build:229: scripts/mod/empty.o] Error 1
make[4]: *** [scripts/Makefile.build:102: scripts/mod/devicetable-offsets.s] Error 1

Mirror other architectures and add all '-mstack-protector-guard' flags
to KBUILD_CFLAGS atomically during stack_protector_prepare, which
resolves the issue and allows clang's implementation to fully work with
the kernel.

Pull powerpc updates from Michael Ellerman:

- Add HOTPLUG_SMT support (/sys/devices/system/cpu/smt) and honour the
configured SMT state when hotplugging CPUs into the system

- Combine final TLB flush and lazy TLB mm shootdown IPIs when using the
Radix MMU to avoid a broadcast TLBIE flush on exit

- Drop the exclusion between ptrace/perf watchpoints, and drop the now
unused associated arch hooks

- Add support for the "nohlt" command line option to disable CPU idle

- Add support for -fpatchable-function-entry for ftrace, with GCC >=
13.1

- Rework memory block size determination, and support 256MB size on
systems with GPUs that have hotpluggable memory

- Various other small features and fixes

powerpc/64s: Move CPU -mtune options into Kconfig

Currently the -mtune options are set in the Makefile, depending on what
the compiler supports.

One downside of doing it that way is that the chosen -mtune option is
not recorded in the .config.

Another downside is that if there's ever a need to do more complicated
logic to calculate the correct option, that gets messy in the Makefile.

So move the determination of which -mtune option to use into Kconfig
logic.

powerpc/ftrace: Add support for -fpatchable-function-entry

GCC v13.1 updated support for -fpatchable-function-entry on ppc64le to
emit nops after the local entry point, rather than before it. This
allows us to use this in the kernel for ftrace purposes. A new script is
added under arch/powerpc/tools/ to help detect if nops are emitted after
the function local entry point, or before the global entry point.

With -fpatchable-function-entry, we no longer have the profiling
instructions generated at function entry, so we only need to validate
the presence of two nops at the ftrace location in ftrace_init_nop(). We
patch the preceding instruction with 'mflr r0' to match the
-mprofile-kernel ABI for subsequent ftrace use.

This changes the profiling instructions used on ppc32. The default -pg
option emits an additional 'stw' instruction after 'mflr r0' and before
the branch to _mcount 'bl _mcount'. This is very similar to the original
-mprofile-kernel implementation on ppc64le, where an additional 'std'
instruction was used to save LR to its save location in the caller's
stackframe. Subsequently, this additional store was removed in later
compiler versions for performance reasons. The same reasons apply for
ppc32 so we only patch in a 'mflr r0'.

powerpc: Fail build if using recordmcount with binutils v2.37

binutils v2.37 drops unused section symbols, which prevents recordmcount
from capturing mcount locations in sections that have no non-weak
symbols. This results in a build failure with a message such as:
Cannot find symbol for section 12: .text.perf_callchain_kernel.
kernel/events/callchain.o: failed

The change to binutils was reverted for v2.38, so this behavior is
specific to binutils v2.37:
https://sourceware.org/git/?p=binutils-gdb.git;a=commit;h=c09c8b42021180eee9495bd50d8b35e683d3901b

Objtool is able to cope with such sections, so this issue is specific to
recordmcount.

Fail the build and print a warning if binutils v2.37 is detected and if
we are using recordmcount.
