uvesafb,vesafb: create WC or WB PAT-entries
with an PAT-enabled kernel, when using uvesafb or vesafb, these drivers will
create uncached-minus PAT entries for the framebuffer memory because they use
ioremap() (not the *_cache or *_wc variants). When the framebuffer memory
intersects with the video RAM used by Xorg, the complete video RAM will be
mapped uncached-minus what results in a serve performance penalty.
Here are the correct MTRR entries created by uvesafb:
schlicht@netbook:~$ cat /proc/mtrr
reg00: base=0x000000000 ( 0MB), size= 2048MB, count=1: write-back
reg01: base=0x06ff00000 ( 1791MB), size= 1MB, count=1: uncachable
reg02: base=0x070000000 ( 1792MB), size= 256MB, count=1: uncachable
reg03: base=0x0d0000000 ( 3328MB), size= 16MB, count=1: write-combining
And here are the problematic PAT entries:
schlicht@netbook:~$ sudo cat /sys/kernel/debug/x86/pat_memtype_list
PAT memtype list:
write-back @ 0x0-0x1000
uncached-minus @ 0x6fedd000-0x6fee3000

Therefore I created the attached patch for uvesafb which uses ioremap_wc() to
create the correct PAT entries, as shown below:

This results in a performance gain, objectively measurable with e.g.
x11perf -comppixwin10 -comppixwin100 -comppixwin500:
1: x11perf_xaa.log
2: x11perf_xaa_patched.log

124000.0 202000.0 ( 1.63) Composite 10x10 from pixmap to window
3340.0 24400.0 ( 7.31) Composite 100x100 from pixmap to window
131.0 1150.0 ( 8.78) Composite 500x500 from pixmap to window
You can see the serve performance gain when composing larger pixmaps to window.
The patches replace the ioremap() function with the variant matching the mtrr-
parameter. To create "write-back" PAT entries, the ioremap_cache() function
must be called after creating the MTRR entries, and the ioremap_cache() region
must completely fit into the MTRR region, this is why the MTRR region size is
now rounded up to the next power-of-two.

Reduce sequential pointer derefs in scsi_error.c and reduce size as well
This patch reduces the number of sequential pointer derefs in
drivers/scsi/scsi_error.c
This has been submitted a number of times over a couple of years. I
believe this version adresses all comments it has gathered over time.
Please apply or reject with a reason.
The benefits are:
- makes the code easier to read. Lots of sequential derefs of the same
pointers is not easy on the eye.
- theoretically at least, just dereferencing the pointers once can
allow the compiler to generally slightly faster code, so in theory
this could also be a micro speed optimization.

matroxfb: remove incorrect Matrox G200eV support
Remove incorrect Matrox G200eV support that was previously added by
commit
e3a1938805d2e81b27d3d348788644f3bad004f2
A serious issue with the incorrect G200eV support that reproduces on the
Matrox G200eV equipped IBM x3650 M2 is the total lack of text (login
banner, login prompt, etc) on the console when X is not running and
total lack of text on all of the virtual consoles after X is started.
Any concerns that the incorrect code (upstream since October 2008) has
been successfully used on non-IBM G200eV equipped system(s) appear to be
unwarranted. In addition to the serious/non-intermittent nature of
issues that have been spotted on IBM systems, complete removal of the
incorrect code is clearly supported by the following Matrox (Yannick
Heneault) provided input:
"It impossible that this patch should have work on a system.
The patch only declare the G200eV as a regular G200 which is
not case. Many registers are different, including at least the
PLL programming sequence. If the G200eV is programmed like a
regular G200, it will not display anything."
v1 - Initial patch that removed the incorrect code for _all_
G200eV equipped systems.
v2 - Darrick Wong provided patch that blacklisted the incorrect
code on G200eV equipped IBM systems leaving it enabled on
all G200eV equipped non-IBM systems.
v3 - Same code changes included with v1 plus additional
justification for complete removal of the incorrect code.

Prevent rt_sigqueueinfo and rt_tgsigqueueinfo from spoofing the signal code
Userland should be able to trust the pid and uid of the sender of a
signal if the si_code is SI_TKILL.
Unfortunately, the kernel has historically allowed sigqueueinfo() to
send any si_code at all (as long as it was negative - to distinguish it
from kernel-generated signals like SIGILL etc), so it could spoof a
SI_TKILL with incorrect siginfo values.
Happily, it looks like glibc has always set si_code to the appropriate
SI_QUEUE, so there are probably no actual user code that ever uses
anything but the appropriate SI_QUEUE flag.
So just tighten the check for si_code (we used to allow any negative
value), and add a (one-time) warning in case there are binaries out
there that might depend on using other si_code values.

introduce sys_syncfs to sync a single file system
It is frequently useful to sync a single file system, instead of all
mounted file systems via sync(2):
- On machines with many mounts, it is not at all uncommon for some of
them to hang (e.g. unresponsive NFS server). sync(2) will get stuck on
those and may never get to the one you do care about (e.g., /).
- Some applications write lots of data to the file system and then
want to make sure it is flushed to disk. Calling fsync(2) on each
file introduces unnecessary ordering constraints that result in a large
amount of sub-optimal writeback/flush/commit behavior by the file
system.
There are currently two ways (that I know of) to sync a single super_block:
- BLKFLSBUF ioctl on the block device: That also invalidates the bdev
mapping, which isn't usually desirable, and doesn't work for non-block
file systems.
- 'mount -o remount,rw' will call sync_filesystem as an artifact of the
current implemention. Relying on this little-known side effect for
something like data safety sounds foolish.
Both of these approaches require root privileges, which some applications
do not have (nor should they need?) given that sync(2) is an unprivileged
operation.
This patch introduces a new system call syncfs(2) that takes an fd and
syncs only the file system it references. Maybe someday we can
$ sync /some/path
and not get
sync: ignoring all arguments
The syscall is motivated by comments by Al and Christoph at the last LSF.
syncfs(2) seems like an appropriate name given statfs(2).
A similar ioctl was also proposed a while back, see

FS_IOC_FIEMAP) it's not harmful IMHO. And remove unnecessary casts
using 'argp' instead.

powerpc/ptrace: Remove BUG_ON when full register set not available
In some cases during a threaded core dump not all the threads will have
a full register set. This happens when the signal causing the core dump
races with a thread exiting. The race happens when the exiting thread
has entered the kernel for the last time before the signal arrives, but
doesn't get far enough through the exit code to avoid being included
in the core dump.
So we get a thread included in the core dump which is never going to go
out to userspace again and only has a partial register set recorded
Normally we would catch each thread as it is about to go into userspace
and capture the full register set then.
However, this exiting thread is never going to go out to userspace
again, so we have no way to capture its full register set. It doesn't
really matter, though, as this is a thread which is effectively
already dead.
So instead of hitting a BUG() in this case (a really bad choice of
action in the first place), we use a poison value for the register
values.

powerpc: Make MPIC honor the "pic-no-reset" device tree property
This property, defined in the Open PIC binding, tells the kernel not to use
the reset bit in the global configuration register. Additionally, its
presence mandates that only sources which are actually used (i.e. appear in
the device tree) should have their VECPRI bits initialized.
Although, "pic-no-reset" can be used for the same use cases that
"protected-sources" is covering, the "protected-sources" implementation was
left completely intact. This is a more pragmatic approach as there are
already several existing systems which use protected sources. If
"pic-no-reset" *and* "protected-sources" are both used, however, then
"pic-no-reset" takes precedence in terms of the init behavior and the
sanity checks done by protected sources will still take place.

powerpc: Document the Open PIC device tree binding
This binding documents several properties that have been in use for quite
some time, and adds one new property 'pic-no-reset', which controls the
runtime initialization behavior of the PIC. More specifically, the presence
of 'pic-no-reset' mandates that the PIC shall not be reset during runtime
initialization and that any initialization related to interrupt sources
shall be limited to sources explicitly referenced in the device tree. This
functionality is useful in AMP systems where multiple OSes are sharing the
PIC and the reinitialization of the PIC can interfere with OSes that are
already up and running.
The interrupt specifier definition is based off of Stuart Yoder's FSL MPIC
binding.

powerpc/pci: Fix crash in PCI code on ppc64 when matching device nodes
Commit
b5d937de0367d26f65b9af1aef5f2c34c1939be0 has a bug which causes
basically a NULL dereference in the PCI code during boot on ppc64
machines.
fetch_dev_dn() is called when dev->dev.of_node is NULL, so using that
as the starting point for the search makes no sense. It should instead
start from the device node of the PHB.

firewire: core: ignore link-active bit of new nodes, fix device recognition
Like the older ieee1394 core driver, firewire-core skipped scanning of
any new node whose PHY sent a self ID without "link active" bit. If a
device had this bit off mistakenly, it meant that it was inaccessible to
kernel drivers with the old IEEE 1394 driver stack but could still be
accessed by userspace drivers through the raw1394 interface.
But with firewire-core, userspace drivers don't get to see such buggy
devices anymore. This is effectively a driver regression since this
device bug is otherwise harmless.
We now attempt to scan all devices, even repeaters that don't have a
link or powered-down devices that have everything but their PHY shut
down when plugged in. This results in futile repeated scanning attempts
in case of such devices that really don't have an active link, but this
doesn't hurt since recent workqueue infrastructure lets us run more
concurrent scanning jobs than we can shake a stick at.
This should fix accessibility of Focusrite Saffire PRO 26 I/O:

firewire: core: increase default SPLIT_TIMEOUT value
The SPLIT_TIMEOUT mechanism is intended to detect requests that somehow
got lost. However, when the timeout value is too low, transactions that
could have been completed successfully will be cancelled. Furthermore,
there are chips whose firmwares ignore the configured split timeout and
send late split response; known examples are the DM1x00 (BeBoB), TCD22x0
(DICE), and some OXUF936QSE firmwares.
This patch changes the default timeout to two seconds, which happens to
be the default on other OSes, too.
Actual lost requests are extremely rare, so there should be no practical
downside to increasing the split timeout even on devices that work
correctly.
