kmemtrace, fs, security: move alloc_secdata() and free_secdata() to linux/security.h
Impact: cleanup
We want to remove percpu.h from rcupdate.h (for upcoming kmemtrace
changes), but this is not possible currently without breaking the
build because fs.h has implicit include file depedencies: it uses
GFP_* types in inlines but does not include gfp.h.
In practice most fs.h using .c files get gfp.h included implicitly,
via an indirect route: via rcupdate.h inclusion - so this underlying
problem gets masked in practice.
So we want to solve fs.h's dependency on gfp.h.
gfp.h can not be included here directly because it is not exported and it
would break the build the following way:
/home/mingo/tip/usr/include/linux/bsg.h:11: found __[us]{8,16,32,64} type without #include <linux/types.h>
/home/mingo/tip/usr/include/linux/fs.h:11: included file 'linux/gfp.h' is not exported
make[3]: *** [/home/mingo/tip/usr/include/linux/.check] Error 1
make[2]: *** [linux] Error 2
As suggested by Alexey Dobriyan, move alloc_secdata() and free_secdata()
to linux/security.h - they belong there. This also cleans fs.h of GFP_*
usage.
