Subject: [GIT PULL] Blackfin fixing for 2.6.23-rc9
Hi Linus,
In this fixing patch sets, including
- fix binfmt_flat Blackfin arch break
- kill compiling checksyscall.pl warning
- fix bfin_mac driver compile failing bug by adding missing gpio pinmux
API which should
be merged at least 1 month ago
IMO, it should be merged in 2.6.23 stable release, so please pull from
'for-linus' branch of
master.kernel.org:/pub/scm/linux/kernel/git/cooloney/blackfin-2.6.git
for-linus
to receive the following updates:
