# 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
