| |
The 2.4.22-pre3 changelog includes: >Alan Cox <alan@lxorguk.ukuu.org.uk>: ... > o add the extra cpu bit test flags
This added a second cpu_has() macro to cpufeature.h, which the patch below cleans up.
Note that FEATURE_EST currently mustn't be used: it resides in the fifth word ([4]) but only four words are allocated (NCAPINTS). If you bump NCAPINTS, you must also adjust the hard-coded struct offsets in arch/i386/kernel/head.S or Very Bad Things happen.
