This patch provides the following hugetlb-related fixes to the recent stacked
shm files changes:
- Update is_file_hugepages() so it will reconize hugetlb shm segments.
- get_unmapped_area must be called with the nested file struct to handle
the sfd->file->f_ops->get_unmapped_area == NULL case.
- The fsync f_op must be wrapped since it is specified in the hugetlbfs
f_ops.
This is based on proposed fixes from Eric Biederman that were debugged and
tested by me. Without it, attempting to use hugetlb shared memory segments
on powerpc (and likely ia64) will kill your box.

The CAPI trace debug functions were using a fixed size buffer, which can be
overflowed if wrong formatted CAPI messages were sent to the kernel capi
layer. The code was also not protected against multiple callers. This fix
bug 8028.
Additionally the patch make the CAPI trace functions optional.

Fix the fact that pte_mkread set _PAGE_RW instead of _PAGE_USER (the logic is
copied from i386 in most place, so it is really as bad as you're thinking).
Thus currently page tables are more permissive than they should.
Such a change may trigger other latent bugs, so be careful with this.

throttle_vm_writeout() is designed to wait for the dirty levels to subside.
But if the caller holds IO or FS locks, we might be holding up that writeout.
So change it to take a single nap to give other devices a chance to clean some
memory, then return.

Rename PG_checked to PG_owner_priv_1 to reflect its availablilty as a

ata_port has two different id fields - id and port_no. id is
system-wide 1-based unique id for the port while port_no is 0-based
host-wide port number. The former is primarily used to identify the
ATA port to the user in printk messages while the latter is used in
various places in libata core and LLDs to index the port inside the
host.
The two fields feel quite similar and sometimes ap->id is used in
place of ap->port_no, which is very difficult to spot. This patch
renames ap->id to ap->print_id to reduce the possibility of such bugs.
Some printk messages are adjusted such that id string (ata%u[.%u])
isn't printed twice and/or to use ata_*_printk() instead of hardcoded
id format.

The current EH speed down code is more of a proof that the EH
framework is capable of adjusting transfer speed in response to error.
This patch puts some intelligence into EH speed down sequence. The
rules are..
* If there have been more than three timeout, HSM violation or
unclassified DEV errors for known supported commands during last 10
mins, NCQ is turned off.
* If there have been more than three timeout or HSM violation for known
supported command, transfer mode is slowed down. If DMA is active,
it is first slowered by one grade (e.g. UDMA133->100). If that
doesn't help, it's slowered to 40c limit (UDMA33). If PIO is
active, it's slowered by one grade first. If that doesn't help,
PIO0 is forced. Note that this rule does not change transfer mode.
DMA is never degraded into PIO by this rule.
* If there have been more than ten ATA bus, timeout, HSM violation or
unclassified device errors for known supported commands && speeding
down DMA mode didn't help, the device is forced into PIO mode. Note
that this rule is considered only for PATA devices and is pretty
difficult to trigger.
One error can only trigger one rule at a time. After a rule is
triggered, error history is cleared such that the next speed down
happens only after some number of errors are accumulated. This makes
sense because now speed down is done in bigger stride.

This is the patch for PATA controller of Celleb.
This driver uses the managed iomap (devres).
Because this driver needs special taskfile accesses, there is
a copy of ata_std_softreset(). ata_dev_try_classify() is exported
so that it can be used in this function.

This reverts commit aeeddc1435c37fa3fc844f31d39c185b08de4158, which was
half-baked and broken. It just resulted in compile errors, since
cpufreq_register_driver() still changes the 'driver_data' by setting
bits in the flags field. So claiming it is 'const' _really_ doesn't
work.

There was OpenVZ specific bug rendering some cpufreq drivers unusable on SMP.
In short, when cpufreq code thinks it confined itself to needed cpu by means
of set_cpus_allowed() to execute rdmsr, some "virtual cpu" feature can migrate
process to anywhere. This triggers bugons and does wrong things in general.
This got fixed by introducing rdmsr_on_cpu and wrmsr_on_cpu executing rdmsr
and wrmsr on given physical cpu by means of smp_call_function_single().
Dave Jones mentioned cpufreq might be not only user of rdmsr_on_cpu() and
wrmsr_on_cpu(), so I'm putting them into arch/{i386,x86_64}/lib/ .
