fbdev: Add GXT4000P and GXT6500P support to the gxt4500 driver
I'm reviving an old patch from 2009 that adds support for GXT4000P and GXT6500P
adapter to the gxt4500 driver.
See threads at http://marc.info/?l=linux-fbdev-devel&m=
124345080216952&w=2
and https://lists.ozlabs.org/pipermail/linuxppc-dev/2009-June/072672.html
for more details.
This patch adds support for GXT4000P and GXT6500P cards found on some
IBM pSeries machines.
GXT4000P/6000P and GXT4500P/6500P couples are identical from
software's point of view and are based on the same Raster Engine
(RC1000), except for a different reference clock for the PLL.
GXT6x00P models are equipped with an additional Geometry Engine
(GT1000) but this driver doesn't use it.

cpuidle/powerpc: Fix snooze state problem in the cpuidle design on pseries.
Earlier without cpuidle framework on pseries, the native arch
idle routine comprised of both snooze and nap
states. smt_snooze_delay variable was used to delay
the idle process entry to deeper idle state like nap.
With the coming of cpuidle, this arch specific idle was replaced
by two different idle routines, one for supporting snooze and other
for nap. This enabled addition of more
low level idle states on pseries in the future.
On adopting the generic cpuidle framework for POWER systems,
the decision of which idle state to choose from, given a predicted
idle time is taken by the menu governor based on
target_residency and exit_latency of the idle states.
target_residency is the minimum time to be resident in that idle state.
Exit_latency is time taken to exit out of idle state.
Deeper the idle state, both the target residency and exit latency
would be higher.
In the current design, smt_snooze_delay is used as target_residency
for the snooze state which is incorrect, as it is not the
minimum but the maximum duration to be in snooze state.
This would result in the governor in taking bad decision,
as presently target_residency of nap < target_residency of snooze
inspite of nap being deeper idle state.
This patch aims to fix this problem by replacing the smt_snooze_delay loop
in snooze state, with the need_resched() as the governor is aware of
entry and exit of various idle transitions based on which
next idle time prediction.
The governor is intelligent enough to determine the idle state the needs to
be transitioned to and maintains a whole of heuristics including
io load, previous idle states predictions etc for the same, based on
which idle state entry decision is taken.
With this fix, of setting target_residency of snooze to 0
nap to smt_snooze_delay
if the predicted idle time is less
than smt_snooze_delay (target_residency of nap)
value governor would pick snooze state, else nap. This adhers to the
previous native idle design.

mm, mempolicy: fix printing stack contents in numa_maps
When reading /proc/pid/numa_maps, it's possible to return the contents of
the stack where the mempolicy string should be printed if the policy gets
freed from beneath us.
This happens because mpol_to_str() may return an error the
stack-allocated buffer is then printed without ever being stored.
There are two possible error conditions in mpol_to_str():
- if the buffer allocated is insufficient for the string to be stored,
and
- if the mempolicy has an invalid mode.
The first error condition is not triggered in any of the callers to
mpol_to_str(): at least 50 bytes is always allocated on the stack and this
is sufficient for the string to be written. A future patch should convert
this into BUILD_BUG_ON() since we know the maximum strlen possible, but
that's not -rc material.
The second error condition is possible if a race occurs in dropping a
reference to a task's mempolicy causing it to be freed during the read().
The slab poison value is then used for the mode and mpol_to_str() returns
-EINVAL.
This race is only possible because get_vma_policy() believes that
mm->mmap_sem protects task->mempolicy, which isn't true. The exit path
does not hold mm->mmap_sem when dropping the reference or setting
task->mempolicy to NULL: it uses task_lock(task) instead.
Thus, it's required for the caller of a task mempolicy to hold
task_lock(task) while grabbing the mempolicy and reading it. Callers with
a vma policy store their mempolicy earlier and can simply increment the
reference count so it's guaranteed not to be freed.

There was a serious disconnect in the logic happening in

Event disable is implemented by programming a NOP event into the PCR.
However, event enable was not reversing this operation. Instead, it

That's not sparc_pmu_enable_event()'s job, that's what

qeth: fix deadlock between recovery and bonding driver
The recovery thread, when failing, tears down the respective interface. To do
so, it needs to obtain the rtnl lock first, as the interface configuration is
changed.
If another process tries to modify an interface setting at the same time, that
process can obtain the rtnl lock first, but the respective callback in the qeth
driver will block until recovery has completed - which cannot happen since the
calling process already obtained it.
In one particular case, the bonding driver acquired the rtnl lock to modify the
card's MAC address, while the recovery failed at the same time due to the card
being removed. Hence qeth_l2_set_mac_address (implicitly holding the rtnl lock)
was waiting on qeth_l2_recover, which deadlocked when waiting on the rtnl lock.
This patch uses rtnl_trylock instead of rtnl_lock in the recovery thread. If the
lock cannot be obtained, the interface will be left up, but the card state
remains in CARD_STATE_RECOVER, which will prevent any further activities on the
card.

The analysis of this is as follows. In init/main.c, we issue:
kernel_thread(kernel_init, NULL, CLONE_FS | CLONE_SIGHAND);
This creates a new thread, which falls through to the ret_from_fork
assembly, with r4 set NULL and r5 set to kernel_init. You can see
this in your oops dump register set - r5 is 0xc0344555, which is the
address of kernel_init plus 1 which marks the function as Thumb code.
Now, let's look at this code a little closer - this is what the
disassembly looks like:
c000d180 <ret_from_fork>:
c000d180: f03a fe08 bl
c0047d94 <schedule_tail>
c000d184: 2d00 cmp r5, #0

c000d19a: bf00 nop
c000d19c: f3af 8000 nop.w
This code was introduced in
9fff2fa0db911 (arm: switch to saner
kernel_execve() semantics). I have marked one instruction, and it's
the significant one - I'll come back to that later.
Eventually, having had a successful call to kernel_execve(), kernel_init()
returns zero.
In returning, it uses the value in 'lr' which was set by the instruction
I marked above. Unfortunately, this causes lr to contain 0xc000d18e -
an even address. This switches the ISA to ARM on return but with a non
word aligned PC value.
So, what do we end up executing? Well, not the instructions above - yes
the opcodes, but they don't mean the same thing in ARM mode. In ARM mode,
it looks like this instead:
c000d18c:
46e946af strbtmi r4, [r9], pc, lsr #13

I have included more above, because it's relevant. The PSR flags which
we can see in the oops dump are nZCv, so Z and C are set.
All the above ARM instructions are not executed, except for two.
c000d1a0, which has no writeback, and writes below the current stack
pointer (and that data is lost when we take the next exception.) The
other instruction which is executed is
c000d1ac, which takes us to...
0xc03493dc. However, remember that bit 1 of the PC got set. So that
makes the PC value 0xc03493de.
And that value is the value we find in the oops dump for PC. What is
the instruction here when interpreted in ARM mode?
0:
f71e150c ; <UNDEFINED> instruction: 0xf71e150c
and there we have our undefined instruction (remember that the 'never'
condition code, 0xf, has been deprecated and is now always executed as
it is now being used for additional instructions.)
This path also nicely explains the state of the stack we see in the oops
dump too.
The above is a consistent and sane story for how we got to the oops
dump, which all stems from the instruction at 0xc000d18a being wrong.

pinctrl/nomadik: provide stubs for legacy Nomadik
The compilation of the pinctrl driver failed on the legacy
Nomadik NHK8815 platform because it was not providing the PRCMU
interfaces needed to support the extended alternate functions
used by the ux500 series.
Solve this by providing some stubs for the legacy platform, to
avoid too much #ifdefs in the code per se. Theoretically this
actually allows the Nomadik and Ux500 to have a single kernel
image with support for the PRCM registers on the Ux500 (though
they have incompatible archs, but the spirit is there).

reason for linux/blk_types.h being exported in the first place. I
discussed this with Jens Axboe before creating the patch.
(3) The big patch of the series to disintegrate include/linux/*.h as a unit.
This could be split up, though there would be collisions in moving stuff
between the two Kbuild files when the parts are merged as that file is
sorted alphabetically rather than being grouped by subsystem.
Of this set of headers, 17 files have changed in the UAPI exported region
since the 4th and only 8 since the 9th so there isn't much change in this
area - as one might expect.
It should be pretty obvious and straightforward if it does come to fixing
up: stuff in __KERNEL__ guards stays where it is and stuff outside moves
to the same file in the include/uapi/linux/ directory.
If a new file appears then things get a bit more complicated as the

ARM: config: sort select statements alphanumerically
As suggested by Andrew Morton:
This is a pet peeve of mine. Any time there's a long list of items
(header file inclusions, kconfig entries, array initalisers, etc) and
someone wants to add a new item, they *always* go and stick it at the
end of the list.
Guys, don't do this. Either put the new item into a randomly-chosen
position or, probably better, alphanumerically sort the list.
lets sort all our select statements alphanumerically. This commit was
created by the following perl:
while (<>) {
while (/\\\s*$/) {
$_ .= <>;
}
undef %selects if /^\s*config\s+/;
if (/^\s+select\s+(\w+).*/) {
if (defined($selects{$1})) {
if ($selects{$1} eq $_) {
print STDERR "Warning: removing duplicated $1 entry\n";
} else {
print STDERR "Error: $1 differently selected\n".
"\tOld: $selects{$1}\n".
"\tNew: $_\n";
exit 1;
}
}
$selects{$1} = $_;
next;
}
if (%selects and (/^\s*$/ or /^\s+help/ or /^\s+---help---/ or
/^endif/ or /^endchoice/)) {
foreach $k (sort (keys %selects)) {
print "$selects{$k}";
}
undef %selects;
}
print;
}
if (%selects) {
foreach $k (sort (keys %selects)) {
print "$selects{$k}";
}
}
It found two duplicates:
Warning: removing duplicated S5P_SETUP_MIPIPHY entry
Warning: removing duplicated HARDIRQS_SW_RESEND entry
and they are identical duplicates, hence the shrinkage in the diffstat
of two lines.
