When allowing some PLL calculation we get a frequency that seems to
be a bit higher than what the OLPC DCON likes resulting in a still
readable but not so good image. We don't really know whether this is
a problem with the calculation formula or the OLPC but as other
displays seem to be happy with the other modes adjusting the OLPC
refresh looks like the better thing. This patch prevents a
regression when dynamic PLL calculation is allowed.

This patch fixes the devices connected on OLPC. The OLPC panel seems
to be connected to DVP1 and LVDS2 for some reasons and if not both
are handled correct the display does not work correct or not at all.
This patch prevents regressions on the OLPC where it worked by
accident but would break in future as the driver did not know the
correct devices connected. This might also fix hardware scaling.
Hopefully the OLPC is the only device with such a requirement but it
will be certainly better to actually know what devices are actually
connected and to not work by accident.

This patch fixes a regression introduced by
fd3cc69848b7e1873e5f12bbcdd572b20277ecf3a
"viafb: remove duplicated clock storage"
caused by an incosistent mode which pretended to have a higher
refresh rate than it actually had. The wrong refresh rate resulted
in a calculated higher pixclock which the OLPC DCON could not handle.
By reducing the refresh rate to 50Hz we get close to the old
pixclock which makes the OLPC display usable again.
Minor other adjustments are needed as 60Hz is assumed to be a safe
value which is not true for OLPC DCON. This is no problem as we only
support 1200x900 on the OLPC.

This patch initializes the margins for the initial mode correct.
This is required to get the desired initial refresh rate. Also do
more verbose sanity checking to prevent misbehavior.

especially for multi-display setups. If you experienced problems

This patch splits the pll configs up on pll versions. This allows
easy adding of other known good pll values. Additionally it made it
possible to remove invalid configurations resulting in better
behaviour for such cases. The resulting clocks are no longer stored
resulting in some computing overhead on each mode change.

The clocks can be easily recalculated by the timing and refresh value.
This brings us one step closer to removing VIAs modetable and use
generic ones and being easier extensible.

Before this patch only clocks that perfectly match were used and if
none existed this was not handled properly. This patch changes this
to always use the closest clock supported. This should behave like
before for clocks that have a perfect match but be much saner for
clocks which are slightly off.

This patch removes the direct lookup table for resolution+refresh and
pixclock by calculating this information from the mode table. Removes a

calculations on each mode change.

These parameters are the same for all currently known VIA IGPs so it
does not make any sense to store them with IGP specific data. This
saves a few bytes and helps a bit in dicovering the real differences.

This patch removes all internal uses of another mostly artificial

it is not flexible as only a few resolutions exist. Hence it is better
to remove it and clean the mess up.

This reverts commit c4ff4b829ef9e6353c0b133b7adb564a68054979.
Ted Ts'o reports:
"TPM is working for me so I can log into employer's network in 2.6.37.
It broke when I tried 2.6.38-rc6, with the following relevant lines
from my dmesg:
[ 11.081627] tpm_tis 00:0b: 1.2 TPM (device-id 0x0, rev-id 78)
[ 25.734114] tpm_tis 00:0b: Operation Timed out
[ 78.040949] tpm_tis 00:0b: Operation Timed out
This caused me to get suspicious, especially since the _other_ TPM
commit in 2.6.38 had already been reverted, so I tried reverting
commit c4ff4b829e: "TPM: Long default timeout fix". With this commit
reverted, my TPM on my Lenovo T410 is once again working."

Several ACPI drivers fail to build if CONFIG_NET is unset, because
they refer to things depending on CONFIG_THERMAL that in turn depends
on CONFIG_NET. However, CONFIG_THERMAL doesn't really need to depend
on CONFIG_NET, because the only part of it requiring CONFIG_NET is
the netlink interface in thermal_sys.c.
Put the netlink interface in thermal_sys.c under #ifdef CONFIG_NET
and remove the dependency of CONFIG_THERMAL on CONFIG_NET from
drivers/thermal/Kconfig.

Commit e2cda3226481 ("thp: add pmd mangling generic functions") replaced
some macros in <asm-generic/pgtable.h> with inline functions.
If the functions are to be defined (not all architectures need them)
then struct vm_area_struct must be defined first. So include
<linux/mm_types.h>.

A customer of ours, complained that when setting the reset
vector back to 0, it trashed other data and hung their box.
They noticed when only 4 bytes were set to 0 instead of 8,
everything worked correctly.
Mathew pointed out:
|
| We're supposed to be resetting trampoline_phys_low and
| trampoline_phys_high here, which are two 16-bit values.
| Writing 64 bits is definitely going to overwrite space
| that we're not supposed to be touching.

Somehow fixes a misrendering + hang at GDM startup on my NVA8...
My first guess would have been stale TLB entries laying around that a new

however, as when we mapped the pages for the new bo the TLBs would've
gotten flushed anyway.

When the per cpu timer is marked CLOCK_EVT_FEAT_C3STOP, then we only
can switch into oneshot mode, when the backup broadcast device
supports oneshot mode as well. Otherwise we would try to switch the
broadcast device into an unsupported mode unconditionally. This went
unnoticed so far as the current available broadcast devices support
oneshot mode. Seth unearthed this problem while debugging and working
around an hpet related BIOS wreckage.
Add the necessary check to tick_is_oneshot_available().

A race can occur when io_submit() races with io_destroy():
CPU1 CPU2
io_submit()
do_io_submit()
...
ctx = lookup_ioctx(ctx_id);
io_destroy()
Now do_io_submit() holds the last reference to ctx.
...
queue new AIO
put_ioctx(ctx) - frees ctx with active AIOs
We solve this issue by checking whether ctx is being destroyed in AIO
submission path after adding new AIO to ctx. Then we are guaranteed that
either io_destroy() waits for new AIO or we see that ctx is being
destroyed and bail out.

In linux rtc_time struct, tm_mon range is 0~11, tm_wday range is 0~6,
while in RTC HW REG, month range is 1~12, day of the week range is 1~7,
this patch adjusts difference of them.
The efect of this bug was that most of month will be operated on as the
next month by the hardware (When in Jan it maybe even worse). For
example, if in May, software wrote 4 to the hardware, which handled it as
April. Then the logic would be different between software and hardware,
which would cause weird things to happen.
