Change the order of fields of struct pid_entry (file fs/proc/base.c) in order to avoid a hole on 64bit archs. (8 bytes saved per object)
Also change all pid_entry arrays to be const qualified, to make clear they must not be modified.
Before (on x86_64) :
# size fs/proc/base.o text data bss dec hex filename 15549 2192 0 17741 454d fs/proc/base.o
After :
# size fs/proc/base.o text data bss dec hex filename 17229 176 0 17405 43fd fs/proc/base.o
Thats 336 bytes saved on kernel size on x86_64
