[MIPS] TX49x7: Fix reporting of the CPU name and PCI clock
I've noticed that PCI clock was incorrectly reported as 66 MHz while being
mere 33 MHz on RBTX4937 board -- this was due to the different encoding of
the PCI divisor field in CCFG register between TX4927 and TX4937 chips...
Also, RBTX49x7 was printed out as a CPU name (e.g., "CPU is RBTX4937");
and some debug printk() were duplicating each other...

[MIPS] Fix linker script to work for non-4K page size.
Very much to my surprise Fuxin Zhang reports this is all it takes to get
the kernel to work for page sizes larger than 4kB. This also paves the
way for support for the R6000 and R8000 which don't support 4kB page size.
I'm pretty sure that the CKSEG0 bits are wrong, but I did need to
cover that region - because the SB-1 kernel links at 0xffffffff80100000
or so, disassembly and printing static variables don't work unless the
debugger can read that region.

[PATCH] VFS: Ensure LOOKUP_CONTINUE flag is preserved by link_path_walk()
When walking a path, the LOOKUP_CONTINUE flag is used by some filesystems
(for instance NFS) in order to determine whether or not it is looking up
the last component of the path. It this is the case, it may have to look
at the intent information in order to perform various tasks such as atomic
open.
A problem currently occurs when link_path_walk() hits a symlink. In this
case LOOKUP_CONTINUE may be cleared prematurely when we hit the end of the
path passed by __vfs_follow_link() (i.e. the end of the symlink path)
rather than when we hit the end of the path passed by the user.
The solution is to have link_path_walk() clear LOOKUP_CONTINUE if and only
if that flag was unset when we entered the function.
