kobject: fix up kobject_set_name to use kvasprintf
Kay pointed out that kobject_set_name was being very stupid, doing two
allocations for every call, when it should just be using the kernel
function kvasprintf() instead.
This change adds the internal kobject_set_name_vargs() function, which
other follow-on patches will be using.

It isn't that hard to add simple kset attributes, so don't go through
all the gyrations of creating your own object type and show and store
functions. Just use the functions that are already present. This makes
things much simpler.
Note, the version_str string violates the "one value per file" rule for
sysfs. I suggest changing this now (individual files per type supported
is one suggested way.)

This patch reorganizes the way suspend and resume notifications are
sent to drivers. The major changes are that now the PM core acquires
every device semaphore before calling the methods, and calls to
device_add() during suspends will fail, while calls to device_del()
during suspends will block.
It also provides a way to safely remove a suspended device with the
help of the PM core, by using the device_pm_schedule_removal() callback
introduced specifically for this purpose, and updates two drivers (msr
and cpuid) that need to use it.

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
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

it checks, on module teardown, if the name of a class is in module space

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.

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.

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.
