A similar fix to netfilter from Eric Dumazet inspired me to

I found where it looks like this semicolon is not valid.

They are apparently pretty close (even lspci combines them). The patch
adds support for 0x1533 bridge in addition to 0x1535.
Tested on Toshiba Portege 4000 with
00:07.0 ISA bridge [0601]: ALi Corporation M1533/M1535 PCI to ISA Bridge
[Aladdin IV/V/V+] [10b9:1533]
00:08.0 Bridge [0680]: ALi Corporation M7101 Power Management Controller
[PMU] [10b9:7101]
with result
[ 2090.906736] PCI: Enabling device 0000:00:08.0 (0000 -> 0001)
[ 2090.914034] ALi_M1535: initialized. timeout=3D60 sec (nowayout=3D0)

There is a bug in the ia64_do_page_fault code that can cause a failure
to grow the register backing store, or any mapping that is marked as
VM_GROWSUP if the mapping is the highest mapped area of memory.
When the address accessed is below the first mapping the previous mapping
is returned as NULL, and this case is handled. However, when the address
accessed is above the highest mapping the vma returned is NULL, this
case is not handled correctly, and it fails to spot that this access
might require an existing mapping to grow upwards.

It seems we have gained an extraneous trailing ';' on one of the
wait loops in scif_sercon_putc(). Although this is completely
benign as the apparent payload is also the empty statement, it
invites error in the future. Clean it up now.

Like the OF device tree, it's useful to let userland get

The core cpufreq code doesn't appear to understand returning -EAGAIN
for the get() function of the cpufreq_driver. If PAL_GET_PSTATE returns
-1, such as when running on Xen, scaling_cur_freq is happy to return
4294967285 kHz (ie. (unsigned)-11). The other drivers appear to return
0 for a failure, and doing so gives me the max frequency from
scaling_cur_frequency and "<unknown>" from cpuinfo_cur_frequency. I
believe that's the desired behavior.

Add empty definition of mmiowb() since some drivers need it. Uncached
writes are strongly ordered on AVR32. They may be delayed if the
dcache is busy doing a writeback, but AFAICT that's not what this
macro is supposed to deal with, at least on UP systems.
We might have to revisit this definition when a SMP-capable AVR32 CPU
comes along, depending on how the busses and cache coherency stuff
end up being implemented.

The current definition of pte_page() masks out valid bits from the
physical address, causing vmalloc_to_page() to misbehave. This may
lead to everything from mmap() silently accessing the wrong data to
"invalid pte" errors dumped by the kernel.
Also remove the now-unused definition of PTE_PHYS_MASK.
Thanks to Matteo Vit for discovering this bug.

There's really no need to retry an allocation with __GFP_REPEAT set.
Also, use get_zeroed_page() and __GFP_ZERO to eliminate the extra call
to clear_page() afterwards.

Fix several inconsistencies in these drivers WRT reporting the clocks:
- when using DPLL mode, 'pata_hpt37x' driver reported the DPLL frequency as the
PCI clock -- make it properly report both clocks and add the same ability to
the 'pata_hpt3x2n' driver;
- both drivers sometimes use "pata_hpt3*:" and sometimes "hpt3*:" in the
messages -- make them use only the former one;
- the message about failed DPLL stablizatios deserves KERN_ERR and a bang. :-)
