Hi,

this is the first and the easiest part of the cleanup - getting rid of
the unused and seldomly used cpu_has_xx uglies. Future work will get rid
of the remaining ones but they need more careful inspection first.

The last patch helps with tinyconfig and slims it down by ~1.5K,
according to 0day numbers:

i386-tinyconfig vmlinux size:

+-------+------+------+-----+---------------------------------------------------------------------------------+
| TOTAL | TEXT | DATA | BSS | |
+-------+------+------+-----+---------------------------------------------------------------------------------+
| -1512 | -352 | 0 | 0 | df63d2e25f80 x86/cpu: Provide a config option to disable static_cpu_has |
| +5 | 0 | 0 | 0 | 8b9e9097bf18 Merge remote-tracking branch 'tip/x86/cleanups' into cpufeature-v3 |
| -1507 | -352 | 0 | 0 | ALL COMMITS |
+-------+------+------+-----+---------------------------------------------------------------------------------+

Stuff is ontop of tip/x86/cleanups because it needs

ed29210cd6a6 ("x86: Remove unused function cpu_has_ht_siblings()")


Thanks.

Borislav Petkov (4):
x86/cpufeature: Move some of the scattered feature bits to x86_capability
x86/cpufeature: Cleanup get_cpu_cap()
x86/cpufeature: Remove unused and seldomly used cpu_has_xx macros
x86/cpu: Provide a config option to disable static_cpu_has
