Subject[PATCH v3 0/3] x86/fpu: Make AMX state ready for CPU idle
Date
Changes from v2 [1]:
* Secure XCR0 accessors from the compiler reordering issue (Dave Hansen).
* Check the feature flag instead of fpu_state_size_dynamic() (Dave Hansen).
* Remove the meaningless backslash (Rafael Wysocki).

Note the two changes this series wants are now in the mainline:
* the opcode for TILERELEASE [2] and
* the C-state table for Sapphire Rapids [3]

The series on top of the above is available here:
git://github.com/intel/amx-linux.git tilerelease

Thanks,
Chang

x86/fpu: Make XCR0 accessors immune to unwanted compiler reordering
x86/fpu: Add a helper to prepare AMX state for low-power CPU idle
intel_idle: Add a new flag to initialize the AMX state
