libata: s/ap->id/ap->print_id/g
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.

libata bugfix: HDIO_DRIVE_TASK
I was trying to use HDIO_DRIVE_TASK for something today,
and discovered that the libata implementation does not copy
over the upper four LBA bits from args[6].
This is serious, as any tools using this ioctl would have their
commands applied to the wrong sectors on the drive, possibly resulting
in disk corruption.
Ideally, newer apps should use SG_IO/ATA_16 directly,
avoiding this bug. But with libata poised to displace drivers/ide,
better compatibility here is a must.
This patch fixes libata to use the upper four LBA bits passed
in from the ioctl.
The original drivers/ide implementation copies over all bits
except for the master/slave select bit. With this patch,
libata will copy only the four high-order LBA bits,
just in case there are assumptions elsewhere in libata (?).

libata: put some intelligence into EH speed down sequence
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 patch stops "modpost" from issuing erroneous modpost warnings on ARM
builds, which it's been doing since since maybe last summer. A canonical
example would be driver method table entries:
WARNING: <path> - Section mismatch: reference to .exit.text:<name>_remove
from .data after '$d' (at offset 0x4)
That "$d" symbol is generated by tools conformant with ARM ABI specs; in
this case it's a symbol **in the middle of** a "<name>_driver" struct.
The erroneous warnings appear to be issued because "modpost" whitelists
references from "<name>_driver" data into init and exit sections ... but
doesn't know should also include those "$d" mapping symbols, which are not
otherwise associated with "<name>_driver" symbols.
This patch prevents the modpost symbol lookup code from ever returning
those mapping symbols, so it will return a whitelisted symbol instead.
Then things work as expected.
Now to revert various code-bloating "fixes" that got merged because of this
modpost bug....

- fixes comment and includes in gpio.h
- replaces the gpio_set/get_value macros with inline

[PATCH] at91_rtc updates
Various bug fixes to the at91rm9200 RTC:
- alarm: setalarm() should pay attention to the "enabled" flag
- init: cleaner handling of the wakeup flags, which cpu init should
really have set up. Doing it here is just a workaround.
- linkage: since the at91_rtc driver probe() routine is in the init
section, it should use platform_driver_probe() instead of leaving
that pointer around in the driver struct after init section removal.
- linkage: likewise, remove() belongs in the exit section.
Among other things, the init and alarm changes ensure that this driver
handles the new sysfs "wakealarm" attribute properly.

Some rtc-sa1100 bugfixes:
- The read_alarm() method reports the rtc_wkalrm.enabled field properly.
This patch is already in the handhelds.org tree.
- And the set_alarm() method now handles that flag correctly, rather than
making mismatched {en,dis}able_irq_wake() calls, which trigger runtime

Note that while this SA1100/PXA RTC is fully capable of waking those ARM

It is possible that a user space application could remove and re-create a

[PATCH] autofs4: fix another race between mount and expire
Jeff Moyer has identified a race between mount and expire.
What happens is that during an expire the situation can arise that a directory
is removed and another lookup is done before the expire issues a completion
status to the kernel module. In this case, since the the lookup gets a new
dentry, it doesn't know that there is an expire in progress and when it posts
its mount request, matches the existing expire request and waits for its
completion. ENOENT is then returned to user space from lookup (as the dentry
passed in is now unhashed) without having performed the mount request.
The solution used here is to keep track of dentrys in this unhashed state and
reuse them, if possible, in order to preserve the flags. Additionally, this
infrastructure will provide the framework for the reintroduction of caching of
mount fails removed earlier in development.

[PATCH] shm: make sysv ipc shared memory use stacked files
The current ipc shared memory code runs into several problems because it
does not quite use files like the rest of the kernel. With the option of
backing ipc shared memory with either hugetlbfs or ordinary shared memory
the problems got worse. With the added support for ipc namespaces things
behaved so unexpected that we now have several bad namespace reference
counting bugs when using what appears at first glance to be a reasonable
idiom.
So to attack these problems and hopefully make the code more maintainable
this patch simply uses the files provided by other parts of the kernel and
builds it's own files out of them. The shm files are allocated in do_shmat
and freed when their reference count drops to zero with their last unmap.
The file and vm operations that we don't want to implement or we don't
implement completely we just delegate to the operations of our backing
file.
This means that we now get an accurate shm_nattch count for we have a
hugetlbfs inode for backing store, and the shm accounting of last attach
and last detach time work as well.
This means that getting a reference to the ipc namespace when we create the
file and dropping the referenece in the release method is now safe and
correct.
This means we no longer need a special case for clearing VM_MAYWRITE
as our file descriptor now only has write permissions when we have
requested write access when calling shmat. Although VM_SHARED is now
cleared as well which I believe is harmless and is mostly likely a
minor bug fix.
By using the same set of operations for both the hugetlb case and regular
shared memory case shmdt is not simplified and made slightly more correct
as now the test "vma->vm_ops == &shm_vm_ops" is 100% accurate in spotting
all shared memory regions generated from sysvipc shared memory.

system at runtime is useful but then we should name this entry
correspondingly, it should return the number of node_ids, and the the value
needs to be setup only once on bootup. The node_possible_map does not
change after bootup.
This patch introduces nr_node_ids and replaces the use of
highest_possible_node_id(). nr_node_ids is calculated on bootup when the
page allocators pagesets are initialized.
