Subject: do not export kernel's NULL #define to userspace
X-Git-Tag: v3.4-rc3~8
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=2084c24a81413b75bc97e4bee56b32ffece70460;p=pandora-kernel.git

do not export kernel's NULL #define to userspace

GCC's NULL is actually __null, which allows detecting some questionable
NULL usage and warn about it.  Moreover each platform/compiler should
have its own stddef.h anyway (which is different from linux/stddef.h).

So there's no good reason to leak kernel's NULL to userspace and
override what the compiler provides.
