Eric W. Biederman f58437f1f9 MIPS: VPE: Remove vpe_getuid and vpe_getgid 
The linux build-bot recently reported a build error in arch/mips/kernel/vpe.c

     tree:   git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace.git for-linus
     head:   261000a56b
     commit: 261000a56b [4/4] userns:  userns: Remove UIDGID_STRICT_TYPE_CHECKS
     config: make ARCH=mips maltaaprp_defconfig

     All error/warnings:

        arch/mips/kernel/vpe.c: In function 'vpe_open':
     >> arch/mips/kernel/vpe.c:1086:9: error: incompatible types when assigning to type 'unsigned int' from type 'kuid_t'

     2600990e Ralf Baechle  2006-04-05  1090 	 	ret = getcwd(v->cwd, VPE_PATH_MAX);

When examining the code to see what v->uid and v->gid were used for I
discovered that the only users in the kernel are vpe_getuid and
vpe_getgid, and that vpe_getuid and vpe_getgid are never called.

So instead of proposing a conversion to use kuid_t and kgid_t instead
of unsigned int/int as I normally would let's just kill this dead code
so no one has to worry about it further.

Deng-Cheng Zhu said:

This is a good catch. vpe_get[u|g]id was originally used by KSPD which
has been removed.
