x86: Simplify code by removing a !SMP #ifdefs from 'struct cpuinfo_x86'
commit 141168c36cdee3ff23d9c7700b0edc47cb65479f and
commit 3f806e50981825fa56a7f1938f24c0680816be45 upstream.
Several fields in struct cpuinfo_x86 were not defined for the
!SMP case, likely to save space. However, those fields still
have some meaning for UP, and keeping them allows some #ifdef
removal from other files. The additional size of the UP kernel
from this change is not significant enough to worry about
keeping up the distinction:
text data bss dec hex filename
4737168 506459 972040 6215667 5ed7f3 vmlinux.o.before
4737444 506459 972040 6215943 5ed907 vmlinux.o.after
for a difference of 276 bytes for an example UP config.
If someone wants those 276 bytes back badly then it should
be implemented in a cleaner way.
