Hi Linus,
Please pull from
git://git.kernel.org:/pub/scm/linux/kernel/git/geert/linux-m68k.git
for-linus
to receive the following m68k-related updates for 2.6.29:
Finn Thain (7):
m68k: Reinstate mac rtc
m68k: Mac via cleanup and commentry
m68k: machw.h cleanup
m68k: mac baboon interrupt enable/disable
macfb annotations and compiler warning fix
m68k: fix trigraph ignored warning in setox.S
fbcon: remove broken mac vbl handler
Geert Uytterhoeven (1):
fbcon: Protect free_irq() by MACH_IS_ATARI check
Harvey Harrison (1):
m68k: use the new byteorder headers
Thanks and a Happy New Year!
