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.
