PCI: Fix fakephp deadlock
This patch works around a problem in the fakephp driver when a process
writing "0" to a "power" sysfs file to fake removal of a PCI device ends
up deadlocking itself in the sysfs code.
The patch was recently accepted into Linus' tree after the 2.6.24 release:

slab: fix bootstrap on memoryless node
[ Upstream commit:
556a169dab38b5100df6f4a45b655dddd3db94c1 ]
If the node we're booting on doesn't have memory, bootstrapping kmalloc()
caches resorts to fallback_alloc() which requires ->nodelists set for all
nodes. Fix that by calling set_up_list3s() for CACHE_CACHE in
kmem_cache_init().
As kmem_getpages() is called with GFP_THISNODE set, this used to work before
because of breakage in 2.6.22 and before with GFP_THISNODE returning pages from
the wrong node if a node had no memory. So it may have worked accidentally and
in an unsafe manner because the pages would have been associated with the wrong
node which could trigger bug ons and locking troubles.

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_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.

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.

The extra rom[0] check is flagging valid temperatures as invalid when
there is already a CRC data transmission check.
w1_therm_read_bin()

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.

do for today. I would like to hear from people who use the ds2490 USB to

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.

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:
http://bugzilla.kernel.org/show_bug.cgi?id=9779
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.

It tried to fix long standing bugzilla entries, but the solution was
reported to break other systems. The reporter of
http://bugzilla.kernel.org/show_bug.cgi?id=9791
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.

- CONFIG_SECURITY_FILE_CAPABILITIES must be defined for the buggy code

[MIPS] Malta: Fix reading the PCI clock frequency on big-endian
The JMPRS register on Malta boards keeps a 32-bit CPU-endian
value. The readw() function assumes that the value it reads is a
little-endian 16-bit number. Therefore, using readw() to obtain
the value of the JMPRS register is a mistake. This error leads
to incorrect reading of the PCI clock frequency on big-endian
during board start-up.
Change readw() to __raw_readl().
This was tested by injecting a call to printk() and verifying
that the value of the jmpr variable was consistent with current
setting of the JP4 "PCI CLK" jumper.

In that patch, David L added a icmp_out_count() in
ip_push_pending_frames(), remove icmp_out_count() from
icmp_reply(). But he forgot to remove icmp_out_count() from
icmp_send() too. Since icmp_send and icmp_reply will call
