proc: fix NULL ->i_fop oops
proc_kill_inodes() can clear ->i_fop in the middle of vfs_readdir resulting in
NULL dereference during "file->f_op->readdir(file, buf, filler)".
The solution is to remove proc_kill_inodes() completely:
a) we don't have tricky modules implementing their tricky readdir hooks which
could keeping this revoke from hell.
b) In a situation when module is gone but PDE still alive, standard
readdir will return only "." and "..", because pde->next was cleared by
remove_proc_entry().
c) the race proc_kill_inode() destined to prevent is not completely
fixed, just race window made smaller, because vfs_readdir() is run
without sb_lock held and without file_list_lock held. Effectively,
->i_fop is cleared at random moment, which can't fix properly anything.

On some systems the number of resources(IO,MEM) returnedy by PNP device is

that some resources can't be reserved and resource confilicts. This will
cause PCI resources are assigned wrongly in some systems, and cause hang.
This is a regression since we deleted ACPI motherboard driver and use PNP

_PAGE_PCD maps a page with caching disabled, which is typically used for

unprivileged guests never need it since they can't see the real underlying
hardware. However, some uncached mappings are made early when probing the
(non-existent) APIC, and its OK to mask off the PCD flag in these cases.
This became necessary because Xen started checking for this bit, rather
than silently masking it off.

Fix boot problem with iSeries lacking hugepage support
Ordinarily the size of a pageblock is determined at compile-time based on the
hugepage size. On PPC64, the hugepage size is determined at runtime based on
what is supported by the machine. With legacy machines such as iSeries that
do not support hugepages, HPAGE_SHIFT is 0. This results in pageblock_order
being set to -PAGE_SHIFT and a crash results shortly afterwards.
This patch adds a function to select a sensible value for pageblock order by
default when HUGETLB_PAGE_SIZE_VARIABLE is set. It checks that HPAGE_SHIFT
is a sensible value before using the hugepage size; if it is not MAX_ORDER-1
is used.
This is a fix for 2.6.24.

the unary detection and bare type regcognition. It also brings the usual
updates for false positives, though these seem to be slowing markedly
now that the unary detector is no longer just putting its finger in the
air and guessing. Of note:
- new --terse mode producing a single line per report
- loosening of the block brace checks
- new checks for enum/union/struch brace placements
- hugely expanded "bare type" detection
- checks for inline usage
- better handling of already open comment blocks
- handle patches which introduce or remove lines without newlines
Andy Whitcroft (19):

Keys needed for both USB-device and USB-interface events are added in
usb_uevent(), which is the bus handler. Keys appropriate only for
USB-device or USB-interface events are added in usb_dev_uevent() or

USB: FIx locks and urb->status in adutux (updated)
Two main issues fixed here are:
- An improper use of in-struct lock to protect an open count
- Use of urb status for -EINPROGRESS
Also, along the way:
- Change usb_unlink_urb to usb_kill_urb. Apparently there's no need
to use usb_unlink_urb whatsoever in this driver, and the old use of
usb_kill_urb was outright racy (it unlinked and immediately freed).
- Fix indentation in adu_write. Looks like it was damaged by a script.
- Vitaly wants -EBUSY on multiply opens.
- bInterval was taken from a wrong endpoint.

sysfs: fix off-by-one error in fill_read_buffer()
I found that there is a off-by-one problem in the following code.
Version: 2.6.24-rc2
File: fs/sysfs/file.c:118-122
Function: fill_read_buffer
--------------------------------------------------------------------
count = ops->show(kobj, attr_sd->s_attr.attr, buffer->page);
sysfs_put_active_two(attr_sd);
BUG_ON(count > (ssize_t)PAGE_SIZE);
--------------------------------------------------------------------
Because according to the specification of the sysfs and the implement of
the show methods, the show methods return the number of bytes which would
be generated for the given input, excluding the trailing null.So if the
return value of the show methods equals PAGE_SIZE - 1, the buffer is full
in fact. And if the return value equals PAGE_SIZE, the resulting string
was already truncated,or buffer overflow occurred.
This patch fixes an off-by-one error in fill_read_buffer.

aec62xx: Fix kernel oops in driver's probe function
Add pci_enable_device() to aec62xx probe function
before doing any I/O.
Original probe function tries to read from device's
PCI region 4 before calling ide_setup_pci_device().
Since the device is not enabled at this point,
on machines that have no firmware PCI initialization
(e.g. ASUS WL-700gE router), corresponding PCI BAR
is 0 and the following inb() causes a kernel oops.

ide: skip ide_wait_not_busy() on noprobe-disks
There is a problem in some hardware where the kernel will stall for
35 seconds waiting for disks that don't exist. This patch will skip
waiting for the BSY-bit on IDE drives to go away if you set "hdx=noprobe"
as a kernel option and the disk is not marked as 'present' (like when
you set the geometry by hand).
If no noprobe-option is set the code will work (more or less) as the
original but if set the code will skip the ide_wait_not_busy() for
that drive. Even if there would be a drive there and it is still busy
afterwards it should not matter since it isn't probed for later.
The code also honors the MAX_DRIVES variable instead of assuming that
there will be two harddrives on the bus.
