Subject: [PATCH] mm/vmstat: Standardize file operations variable names

Standardized the file operation variable names related to all
four memory management /proc interface files. Also changed all
the symbol permissions (S_IRUGO) into octal permissions (0444)
as it got complains from checkpatch.pl script. This does not
create any functional change to the interface.
