If we end up with a fraggap, when we copy the data
over to the next frag being built we must compute
a checksum for the bit we copy over for the new
fragment and subtract that checksum from the place
we are copying it from.

Both work, but the latter can cause warnings in user space
from compilers that don't like using undefined identifiers
in preprocessor expressions (quite reasonable).

It is only taken during boot time bus probe, thus
protects nothing at run time and causes bogus bug
messages when PREEMPT is enabled.  When we support
PCI controller hot plug we will add a suitable locking
mechanism.

This thing was also reimplementing strnchr() as well.

The checkbin target on PPC32 isn't quite right.

First, one of the tests (to ensure that some instructions are known to
gas) is never actually invoked because 'checkbin' doesn't know about
stuff set in .config, so we always have the 'else' case run.  This
changes to always running the test and telling the user to upgrade to at
least binutils 2.12.1.

The next problem is that we were doing $(AS) -o /dev/null ...  in both
that test, as well as another.  The problem here is that the checkbin
target is run on the install targets, meaning that /dev/null will get
unlinked when the test passes.  To get around this we use .tmp_gas_check
as the output file instead.

Acked by Sam.

NFS takes some thought to switch to the new symlink scheme, because we
can't rely on the pagecache lookup to find the symlink page when freeing
it - the cache might have been invalidated in the meantime. 

So we hide the page information in the symlink data area itself,
by stealing the last pointer in the page used for the cache. That
way nfs_put_link() can just look up the page directly.

Massaged altroot handling to avoid on-stack struct nameidata instance (and
got it faster, actually).  We are in the middle of do_follow_link() recursion
here, so the stack footprint is critical.

Both gcc and sparse will speed up tokenization by noticing
when a header file is protected by the standard preprocessor
#ifndef .. #endif exclusion.

However, that requires that the headers actually _use_ that
standard exclusion. Some did their own little broken dance.
