The patch titled
binfmt_flat: minimum support for the Blackfin relocations
has been removed from the -mm tree. Its filename was
binfmt_flat-minimum-support-for-the-blackfin-relocations.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: binfmt_flat: minimum support for the Blackfin relocations
From: Bernd Schmidt <[EMAIL PROTECTED]>
Add minimum support for the Blackfin relocations, since we don't have
enough space in each reloc. The idea is to store a value with one
relocation so that subsequent ones can access it.
Actually, this patch is required for Blackfin. Currently if BINFMT_FLAT is
enabled, git-tree kernel will fail to compile.
