dc4905f459 Remove the old NFS client and server from head, 
which means that the NFSCLIENT and NFSSERVER
kernel options will no longer work. This commit
only removes the kernel components. Removal of
unused code in the user utilities will be done
later. This commit does not include an addition
to UPDATING, but that will be committed in a
few minutes.

3950b58647 Fix the unwinder to get past functions with no stack but may cause an 
exception. In this case no registers will be updated but the link register
will be copied to the program counter to be used to find the calling
function. In this case the program counter may be updated and we should
continue with the trace.

7814dfac2f Add a new sdhci quirk, SDHCI_QUIRK_WAITFOR_RESET_ASSERTED, to work around 
TI OMAP controllers which will return the reset-in-progress bit as zero if
you read the status register too fast after setting the reset bit.

The zero is apparently from a stale snapshot of the internal state presented
in the interface register, and leads to a false indication that the reset
is complete when it either hasn't started yet or is in-progress.  The
workaround is to first loop until the bit is seen as asserted, then do the
normal loop waiting to see it de-asserted.

8f2224905c Fix the watchdog timeout calculation to prevent wrap. The RPi hardware 
can't do a timeout bigger than 15 seconds.  The code wasn't checking for
this and because bitmasking was involved the requested timeout was
basically adjusted modulo-16.  That led to things like a 128 second
timeout actually being a 9 second timeout, which accidentally worked fine
until watchdogd was changed to only pet the dog once every 10 seconds.

If this feels like deja vu... the last time this was fixed in this file
only ARM_MMU_V6 was fixed, this time it's ARM_ARCH_V6 (and this time I
searched for other occurrances of pj4b in here).

2cb1b07d69 When doing a PREREAD sync of an mbuf-type dma buffer, do a writeback of 
the first cacheline if the buffer start address is not on a cacheline
boundary.  Normally a buffer which is not cacheline-aligned is bounced,
but a special rule applies for mbufs, which are always misaligned due to
the header.  We know the cpu will not write to the header while dma is in
progress (so we've been told anyway), but it may have written to the
header shortly before starting a read, so we need to flush that write out
to memory before invalidating the whole buffer.

In collaboration with Mical Meloun and Svata Kraus.
