The C++-like 'template' approach proves to be too ugly and hard to work with.
The old 'template' won't go away until all users are updated.

Current svc_expkey holds a pointer to the svc_export structure, so updates to
that structure have to be in-place, which is a wart on the whole cache
infrastruct. So we break that linkage and just do a second lookup.
If this became a performance issue, it would be possible to put a direct link
back in which was only used conditionally. i.e. when an object is replaced
in the cache, we set a flag in the old object. When dereferencing the link
from svc_expkey, if the flag is set, we drop the reference and do a fresh
lookup.

The 'auth_domain's are simply handles on internal data structures. They do
not cache information from user-space, and forcing them into the mold of a
'cache' misrepresents their true nature and causes confusion.

Fix a gcc warning about losing qualifiers to the first argument of
copy_from_user. The typeof change for correctness, and fixes a lot of the
warnings, but there are some cases where x has some extra qualifiers, like
volatile, which copy_from_user can't know about. For these, the void * cast
seems to be necessary.
Also cleaned up some of the whitespace and got rid of the emacs comment at the
bottom.

The test_bit() routines are defined to work on a pointer to unsigned long.
But thread_info.flags is __u32 (unsigned int) on sh and it is passed to flag
set/clear/test wrappers in include/linux/thread_info.h. So the compiler will
print warnings.
This patch changes to unsigned long instead.

Bitmap functions for the minix filesystem and the ext2 filesystem except
ext2_set_bit_atomic() and ext2_clear_bit_atomic() do not require the atomic
guarantees.
But these are defined by using atomic bit operations on several architectures.
(cris, frv, h8300, ia64, m32r, m68k, m68knommu, mips, s390, sh, sh64, sparc,
sparc64, v850, and xtensa)
This patch switches to non atomic bit operation.
