Subject: [GIT PULL] generic hardirq removal patch for 3.12-rc1

Hi Linus,

please pull from the 'genirq' branch of

	git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux.git genirq

to receive the following updates:
All architectures now use generic hardirqs, s390 has been last to
switch. With that the code under CONFIG_GENERIC_HARDIRQS and the
related HAVE_GENERIC_HARDIRQS and GENERIC_HARDIRQS config options
can be removed. Yay!

Martin Schwidefsky (1):
      Remove GENERIC_HARDIRQ config option
