This converts ide_cd_queue_pc to use blk_execute_rq, necessitating
changing the ide_cd_queue_pc prototype into a form that doesn't takes
a pointer to request struct. ide_cd_queue_pc works like scsi_execute.

* Call __elv_add_request() with 'plug' == 1 (so the device will be
plugged) and then use __generic_unplug_device() instead of calling
ide_do_request() directly.
v2:
* For blk_pm_resume_request() requests the queue is stopped so we
need to call ->request_fn explicitly.
Thanks to:
- Rafael for reporting/bisecting the bug
- Borislav/Rafael for testing the fix
This is a preparation for converting IDE to use blk_execute_rq().

* Set REQ_PREEMPT request flag in ide_do_drive_cmd() users

* Set 'where' variable outside ide_lock.
This is a preparation for converting IDE to use blk_execute_rq().
There should be no functional changes caused by this patch.

Replace the FIT() macro with the kernel-provided clamp_val() macro.
FIT was always being called with a member of a struct ide_timing,
which are shorts, and constant constraints for the min and max.
Thus we can use clamp_val, rather than clamp_t.

Since ide_driveid_update() uses polling to execute the IDENTIFY DEVICE command
but clears nIEN bit in the control register and doesn't mask the IDE interrupt,
the latter does happen and lead to the corresponding message to appear:
ide0: unexpected interrupt, status=0x58, count=1
when e.g. running hdparm with option -X with a non-PCI IDE driver...

SGI-IP28 is running in so called slow mode, when kernel is started

Both the fill_ipi_map() routine and the gic_intr_map array defined
in arch/mips/mips-boards/malta/malta_int.c are not used outside of
the latter file. Thus, these objects can become static. Moreover,
these two objects are used by the MT code only, which is why this
patch adds the appropriate ifdef.
While at it, this patch removes an unnecessary preprocessing macro
in favor of the commonly used ARRAY_SIZE.
