Subject: [PATCH resend 0/10] Get rid of FIQ_START/enable/disable_fiq() + some
 FIQ cleanups

Hello Andrew, Russell,

These are small cleanups that I keep resending since Aug. Andrew, can you
please take them for the time being?

The rationale is the same:

During KDB FIQ patches review Russell mentioned that I should not
introduce another FIQ_START. It seems that in v3.6-rc the FIQ_START issue
was somewhat band-aided, i.e. machines don't necessary need to define this
stuff any longer, but I also read the background of the issue, and Russell
once said that he don't want the FIQ subsystem to mess with genirq.

So, the patch set is pretty straightforward:

- Get rid of FIQ_START. Nobody but platform-specific code (and
  platform-specific drivers) should know the details about which interrupt
  can be routed to FIQ and which cannot;

- Remove disable/enable_fiq() calls from the FIQ subsys.

Thanks!
