[PATCH] kernel/cpu.c: fix many errors related to style.

[Matej Dujava]

This patch fixes the checkpatch.pl warning:
ERROR: spaces required around that '=' (ctx:VxW)
WARNING: Block comments use a trailing */ on a separate line
CHECK: Please don't use multiple blank lines
CHECK: Blank lines aren't necessary before a close brace '}'
CHECK: braces {} should be used on all arms of this statement
CHECK: Blank lines aren't necessary after an open brace '{'
