This is the right one:

	ftp://ftp.us.kernel.org/pub/linux/kernel/people/andrea/kernels/v2.4/2.4.8aa1/00_cachelinealigned-in-smp-1

Alan also merged it in -ac IIRC.

BTW, for your other patch you sent a few hours ago you forgot to drop
the KMAP entry that is wasting NR_CPUS*PAGE_SIZE of virtual address
space:

	ftp://ftp.us.kernel.org/pub/linux/kernel/people/andrea/kernels/v2.4/2.4.8aa1/00_create_bounces-sleeps-1
