Subject: [BUG] compiler warning, kernel 2.6.16

If CONFIG_SWAP is _not_ set, gcc complains:

/src/linux-2.6.16-tfix/mm/vmscan.c: In function `remove_mapping':
/src/linux-2.6.16-tfix/mm/vmscan.c:398: warning: unused variable `swap'

Yes, that's been there for ages. That code will be eliminated by the
compiler and I tend to think that the ugliness of making the warning go
away exceeds the benefit of stomping a !CONFIG_SWAP compile warning.
