Stop gcc from generating uninitialised variable warnings after BUG().
The problem is that FRV's call into its gdbstub appears to return (if
the function is marked noreturn, then the compiler is under no
obligation to pass it a return address, and so GDB won't know where the
bug happened).
To get around this, we make the do...while wrapper in _debug_bug_trap()
an endless loop from which there's no escape.

Fix a number of miscellanous items:
(1) Declare lock sections in the linker script.
(2) Recurse in the correct manner in the arch makefile.
(3) asm/bug.h requires asm/linkage.h to be included first. One C file puts
asm/bug.h first.
(4) Add an empty RTC header file to avoid missing header file errors.
(5) sg_dma_address() should use the dma_address member of a scatter list.
(6) Add trivial pci_unmap support.
(7) Add pgprot_noncached()
(8) Discard u_quad_t.
(9) Use ~0UL rather than ULONG_MAX in unistd.h in case the latter isn't
declared.
(10) Add an empty VGA header file to avoid missing header file errors.
(11) Add an XOR header file to use the generic XOR stuff.

This patch eliminates all kernel BUGs, trims about 35k off the typical
kernel, and makes the system slightly faster.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
