spi: omap2_mcspi PIO RX fix
Before transmission of the last word in PIO RX_ONLY mode rx+tx mode
is enabled:
/* prevent last RX_ONLY read from triggering
* more word i/o: switch to rx+tx
*/
if (c == 0 && tx == NULL)
mcspi_write_cs_reg(spi,
OMAP2_MCSPI_CHCONF0, l);
But because c is decremented after the test, c will never be zero and
rx+tx will not be enabled. This breaks RX_ONLY mode PIO transfers.
Fix it by decrementing c in the beginning of the various I/O loops.

at least we won't unnecessarily worry users.

fix hugepages leak due to pagetable page sharing
The shared page table code for hugetlb memory on x86 and x86_64
is causing a leak. When a user of hugepages exits using this code
the system leaks some of the hugepages.
-------------------------------------------------------
Part of /proc/meminfo just before database startup:
HugePages_Total: 5500
HugePages_Free: 5500
HugePages_Rsvd: 0
Hugepagesize: 2048 kB
Just before shutdown:
HugePages_Total: 5500
HugePages_Free: 4475
HugePages_Rsvd: 0
Hugepagesize: 2048 kB
After shutdown:
HugePages_Total: 5500
HugePages_Free: 4988
HugePages_Rsvd:
0 Hugepagesize: 2048 kB
----------------------------------------------------------
The problem occurs durring a fork, in copy_hugetlb_page_range(). It
locates the dst_pte using huge_pte_alloc(). Since huge_pte_alloc() calls
huge_pmd_share() it will share the pmd page if can, yet the main loop in
copy_hugetlb_page_range() does a get_page() on every hugepage. This is a
violation of the shared hugepmd pagetable protocol and creates additional
referenced to the hugepages causing a leak when the unmap of the VMA
occurs. We can skip the entire replication of the ptes when the hugepage
pagetables are shared. The attached patch skips copying the ptes and the
get_page() calls if the hugetlbpage pagetable is shared.

lockdep: fix kernel crash on module unload
Michael Wu noticed in his lkml post at
that certain wireless drivers ended up having their name in module
memory, which would then crash the kernel on module unload.
The patch he proposed was a bit clumsy in that it increased the size of
a lockdep entry significantly; the patch below tries another approach,
it checks, on module teardown, if the name of a class is in module space
and then zaps the class. This is very similar to what we already do
with keys that are in module space.

Linux does not want BIOS writers to invoke _OSI(Linux) -
for in the field it causes more Windows incompatibility problems

So when it is seen in the BIOS for an Intel Customer Reference Board,
Linux should ignore its effect by default, and should complain loudly.
Otherwise, the reference BIOS will go unfixed, and the bad BIOS
will spread to the field.
Users of this board can get the old behavior with "acpi_osi=Linux"

same datums it used to.
The change made transformations like turning:
"srom + 34"
into
"(__le32 *)srom + 34/4"
which doesn't work because 4 does not divide evenly
into 34 so we're using a different pointer offset
than in the original code.
I've changed theses cases in dmfe_parse_srom() to
consistently use "(type *)(srom + offset)" preserving
the offsets from the original code.

x86: GEODE fix a race condition in the MFGPT timer tick
When we set the MFGPT timer tick, there is a chance that we'll
immediately assert an event. If for some reason the IRQ routing
for this clock has been setup for some other purpose, then we
could end up firing an interrupt into the SMM handler or worse.
This rearranges the timer tick init function to initalize the handler
before we set up the MFGPT clock to make sure that even if we get
an event, it will go to the handler.
Furthermore, in the handler we need to make sure that we clear the
event, even if the timer isn't running.

W1: w1_therm.c is flagging 0C etc as invalid
The extra rom[0] check is flagging valid temperatures as invalid when
there is already a CRC data transmission check.
w1_therm_read_bin()
if (rom[8] == crc && rom[0])
verdict = 1;
Requiring rom[0] to be non-zero will flag as invalid temperature
conversions when the low byte is zero, specifically the temperatures 0C,
16C, 32C, 48C, -16C, -32C, and -48C.
The CRC check is produced on the device for the previous 8 bytes and is
required to ensure the data integrity in transmission. I don't see why the
extra check for rom[0] being non-zero is in there. Evgeniy Polyakov didn't
know either. Just for a check I unplugged the sensor, executed a
temperature conversion, and read the results. The read was all ff's, which
also failed the CRC, so it doesn't need to protect against a disconnected
sensor.
I have more extensive patches in the work, but these two trivial ones will
do for today. I would like to hear from people who use the ds2490 USB to
one wire dongle. 1 if you would be willing to test the patches as I
currently only have the one sensor on a short parisite powered wire, 2 if
there is any cheap sources for the ds2490.

W1: w1_therm.c ds18b20 decode freezing temperatures correctly
Correct the decoding of negative C temperatures. The code did a binary OR
of two bytes to make a 16 bit value, but assignd it to an integer. This
caused the value to not be sign extended and to loose that it was a
negative number in the assignment.
Before the patch (in my freezer),
w1_slave
ed fe 4b 46 7f ff 03 10 e4 : crc=e4 YES
ed fe 4b 46 7f ff 03 10 e4 t=4078
With the patch,

hwmon: (it87) request only Environment Controller ports
The IT8705F and related parts are Super I/O controllers that contain
many separate devices.
Some BIOSes describe IT8705F I/O port usage under a motherboard device
(PNP0C02) with overlapping regions, e.g., 0x290-0x29f and 0x290-0x294.
The it87 driver supports only the Environment Controller, which requires
only two ISA ports, but it used to request an eight-port range. If that
range exceeds a range reported by the BIOS, as 0x290-0x297 would, the
request fails, and the it87 driver cannot claim the device.
This patch makes the it87 driver request only the two ports used for the
Environment Controller device.
Systems where this problem has been reported:
Gigabyte GA-K8N Ultra 9
Gigabyte M56S-S3
Gigabyte GA-965G-DS3

Related change:
The patch above increases the number of PNP port resources we support.
Prior to this patch, we ignored some port resources, which masked the
it87 problem.

sched: group scheduler, set uid share fix
setting cpu share to 1 causes hangs, as reported in:
as the default share is 1024, the values of 0 and 1 can indeed
cause problems. Limit it to 2 or higher values.
These values can only be set by the root user - but still it
makes sense to protect against nonsensical values.

Revert "x86: fix NMI watchdog & 'stopped time' problem"
This reverts commit d4d25deca49ec2527a634557bf5a6cf449f85deb.
It tried to fix long standing bugzilla entries, but the solution was
reported to break other systems. The reporter of
tracked it down to this commit and confirmed that reverting the patch
restores the correct behaviour. It's too late in the release cycle to
find a better solution than reverting the commit to avoid regressions.

[SPARC64]: Fix section error in sparcspkr
With a sparc64 defconfig modified to set CONFIG_HOTPLUG=n
the following error happened during link of vmlinux:
local symbol 0: discarded in section `.devexit.text' from drivers/built-in.o
local symbol 1: discarded in section `.devexit.text' from drivers/built-in.o
(The error message above is from kbuild.git but it happens in mainline too)
The error happens becase there is a reference from .text/.data to a
function marked __devexit. With CONFIG_HOTPLUG=n all code marked
__devexit are discarded and the linker complains.
It was tracked down to sparcspkr.c which were missing __devexit_p()
around the function pointers.
Unfortunately modpost did not catch this since modpost do not warn
about references from .data to .devexit from variables named *_driver.

For the vio.c case it was a function with a wrong annotation which was removed.

Fix filesystem capability support
In linux-2.6.24-rc1, security/commoncap.c:cap_inh_is_capped() was
introduced. It has the exact reverse of its intended behavior. This
led to an unintended privilege esculation involving a process'
inheritable capability set.
To be exposed to this bug, you need to have Filesystem Capabilities
enabled and in use. That is:
- CONFIG_SECURITY_FILE_CAPABILITIES must be defined for the buggy code
to be compiled in.
- You also need to have files on your system marked with fI bits raised.
