The old NO_IRQ define some platforms had was long ago declared obsolete
and wrong. FRV should therefore not be re-introducing this, especially as
IRQs are usually unsigned in the kernel. The "no IRQ" case is defined to be
zero and Linus made this rather clear at the time.
arch/frv shows no dependancy on this but it might show up driver fixes
needing doing I guess

Credit goes to juergen.kadidlo@exasol.com for diagnosing this issue
and supplying the initial patch.
blk_queue_invalidate_tags() must use the proper requeueing paths instead
of open coding the re-add of the request, otherwise we bug out in rq
accounting. Just switch to using blk_requeue_request(), that takes care
of end-tag handling as well and also adds the blktrace REQUEUE notify
event that is also appropriate here.

One-shot timer mode on PXA has various bugs which prevent kernels
build with NO_HZ enabled booting. They end up spinning on a
permanently asserted timer interrupt because we don't properly
clear it down - clearing the OIER bit does not stop the pending
interrupt status. Fix this in the set_mode handler as well.
Moreover, the code which sets the next expiry point may race with
the hardware, and we might not set the match register sufficiently
in the future. If we encounter that situation, return -ETIME so
the generic time code retries.

For kernel addresses between TASK_SIZE and PAGE_OFFSET,
flush_tlb_kern_range() does not work as would be expected.
The TLB invalidate works with a matching ASID, or on entries marked as
global. The set_pte_at() macro marks addresses >= PAGE_OFFSET as
global, but not addresses from TASK_SIZE to PAGE_OFFSET, which are
also kernel addresses.
The result is that the entries in this range are not actually
invalidated by flush_tlb_kern_range().
This patch instead marks addresses >= TASK_SIZE as global.

When I fixed the windfarm freezer interaction first in commit
1ed2ddf380e19dafeec2150ca709ef7f4a67cd21, an earlier patch than the one
I came up with after comments was committed. This has come back to haunt
us now because commit d5d8c5976d6adeddb8208c240460411e2198b393 changed
the freezer to no long send signals. Fix it by removing the windfarm
thread's signal logic and restoring the original try_to_freeze().
We could simply revert 1ed2ddf380e19dafeec2150ca709ef7f4a67cd21 now
but I feel that the assertion that no signal is delivered to the
windfarm thread needs not be there.

If the low level MMU hash table insertion returns an error (which
can happen in some rare circumstances when the hypervisor refuses
the insertion of a PTE, typically if you try to access junk via
/dev/mem), the generated signal had an incorrect si_addr value due
to a bug in the assembly, which was loading it as a 32 bits quantity
instead of a 64 bits quantity.

The decrementer in Book E and 4xx processors interrupts on the
transition from 1 to 0, rather than on the 0 to -1 transition as on
64-bit server and 32-bit "classic" (6xx/7xx/7xxx) processors. At the
moment we subtract 1 from the count of how many decrementer ticks are
required before the next interrupt before putting it into the
decrementer, which is correct for server/classic processors, but could
possibly cause the interrupt to happen too early on Book E and 4xx if
the timebase/decrementer frequency is low.
This fixes the problem by making set_dec subtract 1 from the count for
server and classic processors, instead of having the callers subtract
1. Since set_dec already had a bunch of ifdefs to handle different
processor types, there is no net increase in ugliness. :)
Note that calling set_dec(0) may not generate an interrupt on some
processors. To make sure that decrementer_set_next_event always calls
set_dec with an interval of at least 1 tick, we set min_delta_ns of
the decrementer_clockevent to correspond to 2 ticks (2 rather than 1
to compensate for truncations in the conversions between ticks and
ns).
This also removes a redundant call to set the decrementer to
0x7fffffff - it was already set to that earlier in timer_interrupt.

Now that we have 1TB segment size support, we need to be using the
GET_ESID_1T macro when comparing ESID values for pc, stack, and
unmapped_base within switch_slb(). A new helper function called
esids_match() contains the logic for deciding when to call GET_ESID
and GET_ESID_1T.
This fixes a duplicate-slb-entry inspired machine-check exception I
was seeing when trying to run java on a power6 partition.
Tested on power6 and power5.

We had an historical confusion in the kernel between cache line
and cache block size. The former is an implementation detail of
the L1 cache which can be useful for performance optimisations,
the later is the actual size on which the cache control
instructions operate, which can be different.
For some reason, we had a weird hack reading the right property
on powermac and the wrong one on any other 64 bits (32 bits is
unaffected as it only uses the cputable for cache block size
infos at this stage).
This fixes the booting-without-of.txt documentation to mention
the right properties, and fixes the 64 bits initialization code
to look for the block size first, with a fallback to the line
size if the property is missing.

The ps3 target produces two images, and the binary one is not the
"primary" image that corresponds to the -o flag; thus, it no longer
uses the generic binary flag.
On platforms which do use the binary flag, it no longer produces a
.bin suffix, so that the output file matches what was passed to the -o flag.
This should fix the zImage ln problems for the ps3 target.

There are plans afoot to use pci_restore_msi_state() to restore MSI
state after a device reset. In order for this to work for the RTAS MSI
backend, we need to read back the MSI message from config space after
it has been setup by firmware.
This should be sufficient for restoring the MSI state after a device
reset, however we will need to revisit this for suspend to disk if that
is ever implemented on pseries.
