[PATCH] SELinux: convert to kzalloc
This patch converts SELinux code from kmalloc/memset to the new kazalloc
unction. On i386, this results in a text saving of over 1K.
Before:
text data bss dec hex filename
86319 4642 15236 106197 19ed5 security/selinux/built-in.o
After:
text data bss dec hex filename
85278 4642 15236 105156 19ac4 security/selinux/built-in.o
