Linus,

Please pull the latest x86/percpu Git tree from:

git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git x86-percpu-2024-05-13

# HEAD: 93cfa544cf9e4771def159002304a2e366cd97af x86/percpu: Introduce raw_cpu_read_long() to reduce ifdeffery

x86/percpu changes for v6.10:

- Expand the named address spaces optimizations down to
GCC 9.1+.

- Re-enable named address spaces with sanitizers for GCC 13.3+

- Generate better this_percpu_xchg_op() code

- Introduce raw_cpu_read_long() to reduce ifdeffery

- Simplify the x86_this_cpu_test_bit() et al macros

- Address Sparse warnings

- Misc cleanups & fixes

Thanks,

Ingo
