[PATCH] [RESEND] spufs: use timespec64 for timestamps

The switch log prints the tv_sec portion of timespec as a 32-bit number, while overflows in 2106. It also uses the timespec type, which is safe on 64-bit architectures, but deprecated because it causes overflows in 2038 elsewhere. This changes it to timespec64 and printing a 64-bit number for cons

In an effort to remove all instances of 'struct timeval' from the kernel, I'm changing the powerpc mpic_timer interface to use plain seconds instead. There is only one user of this interface, and that doesn't use the microseconds portion, so the code gets noticeably simpler in the process. Signed-

[PATCH] nfs/super: check NFS_CAP_ACLS instead of the NFS version

This sets MS_POSIXACL only if ACL support is really enabled, instead of always setting MS_POSIXACL if the NFS protocol version theoretically supports ACL. The code comment says "We will [apply the umask] ourselves", but that happens in posix_acl_create() only if the kernel has POSIX ACL support.
