[BK PATCH] LSM changes for 2.5.44

[Greg KH]

This is a resend of my previous series of LSM patches for 2.5.43 that
change the way the LSM hooks operate (now they can be compiled away into
nothing).  I've also added the sys_security removal patch from Christoph
Hellwig as everyone agrees that the idea of sys_security is good, but
the current implementation sucks.

thanks,

  [PATCH] remove sys_security
  
  I've been auditing the LSM stuff a bit more..
  
  They have registered an implemented a syscall, sys_security
  that does nothing but switch into the individual modules
  based on the first argument, i.e. it's ioctl() switching
  on the security module instead of device node.  Yuck.
  
  Patch below removes it (no intree users), maybe selinux/etc
  folks should send their actual syscall for review instead..

  This allows the security hooks to be compiled away into nothingness if CONFIG_SECURITY
