Commit d065bd810b
(mm: retry page fault when blocking on disk transfer) and
commit 37b23e0525
(x86,mm: make pagefault killable)
The above commits introduced changes into the x86 pagefault handler
for making the page fault handler retryable as well as killable.
These changes reduce the mmap_sem hold time, which is crucial
during OOM killer invocation.

Here is the big staging tree pull request for the 3.5-rc1 merge window.
Loads of changes here, and we just narrowly added more lines than we
added:
622 files changed, 28356 insertions(+), 26059 deletions(-)
But, good news is that there is a number of subsystems that moved out of
the staging tree, to their respective "real" portions of the kernel.
Code that moved out was:
- iio core code
- mei driver
- vme core and bridge drivers
There was one broken network driver that moved into staging as a step
before it is removed from the tree (pc300), and there was a few new
drivers added to the tree:
- new iio drivers
- gdm72xx wimax USB driver
- ipack subsystem and 2 drivers
All of the movements around have acks from the various subsystem
maintainers, and all of this has been in the linux-next tree for a

Clean up: Continue to rationalize the locking in nfs_get_client() by
moving the logic that handles the case where a matching server IP
address is not found.
When we support server trunking detection, client initialization may
return a different nfs_client struct than was passed to it. Change
the synopsis of the init_client methods to return an nfs_client.
The client initialization logic in nfs_get_client() is not much more
than a wrapper around ->init_client. It's simpler to keep the little
bits of error handling in the version-specific init_client methods.

Currently our NFS client assigns a unique SETCLIENTID boot verifier
for each server IP address it knows about. It's set to CURRENT_TIME
when the struct nfs_client for that server IP is created.
During the SETCLIENTID operation, our client also presents an
nfs_client_id4 string to servers, as an identifier on which the server
can hang all of this client's NFSv4 state. Our client's
nfs_client_id4 string is unique for each server IP address.
An NFSv4 server is obligated to wipe all NFSv4 state associated with
an nfs_client_id4 string when the client presents the same
nfs_client_id4 string along with a changed SETCLIENTID boot verifier.
When our client unmounts the last of a server's shares, it destroys
that server's struct nfs_client. The next time the client mounts that
NFS server, it creates a fresh struct nfs_client with a fresh boot
verifier. On seeing the fresh verifer, the server wipes any previous
NFSv4 state associated with that nfs_client_id4.
However, NFSv4.1 clients are supposed to present the same
nfs_client_id4 string to all servers. And, to support Transparent
State Migration, the same nfs_client_id4 string should be presented
to all NFSv4.0 servers so they recognize that migrated state for this
client belongs with state a server may already have for this client.
(This is known as the Uniform Client String model).
If the nfs_client_id4 string is the same but the boot verifier changes
for each server IP address, SETCLIENTID and EXCHANGE_ID operations
from such a client could unintentionally result in a server wiping a
client's previously obtained lease.
Thus, if our NFS client is going to use a fixed nfs_client_id4 string,
either for NFSv4.0 or NFSv4.1 mounts, our NFS client should use a
boot verifier that does not change depending on server IP address.
Replace our current per-nfs_client boot verifier with a per-nfs_net
boot verifier.

nfs4_reset_all_state() refreshes the boot verifier a server sees to
trigger that server to wipe this client's state. This function is
invoked when an NFSv4.1 server reports that it has revoked some or
all of a client's NFSv4 state.
To facilitate server trunking discovery, we will eventually want to
move the cl_boot_time field to a more global structure. The Uniform
Client String model (and specifically, server trunking detection)
requires that all servers see the same boot verifier until the client
actually does reboot, and not a fresh verifier every time the client
unmounts and remounts the server.
Without the cl_boot_time field, however, nfs4_reset_all_state() will
have to find some other way to force the server to purge the client's
NFSv4 state.
Because these verifiers are opaque (ie, the server doesn't know or
care that they happen to be timestamps), we can force the server
to wipe NFSv4 state by updating the boot verifier as we do now, then
immediately afterwards establish a fresh client ID using the old boot
verifier again.
Hopefully there are no extra paranoid server implementations that keep
track of the client's boot verifiers and prevent clients from reusing
a previous one.

them with device tree based descriptions, a lot of platforms have not
come that far:
In shmobile, we add two new board files because their recently started
effort to add DT support has not proceeded enough to use it for all of
the important hardware.
In Kirkwood, we are adding support for new boards with a combination of
DT and board file contents in multiple cases.
pxa/mmp and imx are extending support for existing board files but not
adding new ones.

"While we generally attempt to get rid of board specific files and
replace them with device tree based descriptions, a lot of platforms
have not come that far:
In shmobile, we add two new board files because their recently started
effort to add DT support has not proceeded enough to use it for all of
the important hardware.

This is (obviously) the last non-fix pull request for wireless bits
intended for 3.5. It includes AP support for mwifiex, a variety of HCI
and other updates for NFC, some brcmfmac and brcmsmac refactoring,
a large batch of ssb and bcma updates, a batch of ath6kl updates,
some cfg80211 and mac80211 updates/refactoring from Johannes Berg,
a rather large collection of Bluetooth updates by way of Gustavo,
and a variety of other bits here and there.

A user has several systems with a couple of models of flash disks with IDE
connectors. These disks work fine in 2.6.18-ish kernels but corrupt data on
new kernels.
The difference appears to be with the default I/O method used by the IDE
controller driver between the kernels. In the older kernels, the
configuration is very conservative and the driver stays in PIO mode. With
new kernels, the ata driver (pata_serverworks) attempts to use UDMA/66
which the drive claims to support. This mode, however, does not appear to
work in DMA mode. The drive does work correctly and no corruption is
seen if the kernel parameter "libata.force=5:pio0,6:pio0" is used to force
the driver to use PIO instead of DMA mode.
Blacklist these drives. Unfortunately the model name of the drive is very
generic, " 2GB ATA Flash Disk", but the revision is specific, "ADMA428M".

When ata_generic_ide=1 is set don't do the is_intel_ider() magic
check. We found at least one box who needed that.
