X-Git-Tag: v2.6.13-rc6~11
X-Git-Url: http://www.pilppa.org/gitweb/gitweb.cgi?a=commitdiff_plain;h=9ae5b3c703cce89a7d8ccf25fe16955ec6f016c0;p=linux-2.6-omap-h63xx.git

[PATCH] remove linux/pagemap.h from linux/swap.h

sparc can not include linux/pagemap.h because of the following circular
dependency:

asm-sparc/pgtable include linux/swap.h
linux/swap.h include now linux/pagemap.h
linux/pagemap.h include linux/mm.h
linux/mm.h include asm/pgtable.h

It needs to have the swp_entry_t type fully visible in pgtable.h,
we can't work around this using macros.
