This fixes the builtin RTL8139 NIC on the Medion MD9580-F laptop. The BIOS reports the interrupt routing incorrectly. I recently added a quirk to work around this, and this patch fixes a typo in the quirk. We pad every ACPI pathname component to four characters, so ".ISA." will never match anything. We need ".ISA_." instead. Thank you Johann-Nikolaus Andreae <johann-nikolaus.andreae@nacs.de> for patiently testing this patch. See http://bugzilla.kernel.org/show_bug.cgi?id=4773Signed-off-by:

While backporting 72dc67a6, a gfn_to_page() call was duplicated instead of moved (due to an unrelated patch not being present in mainline). This caused a page reference leak, resulting in a fairly massive memory leak. Fix by removing the extraneous gfn_to_page() call. Signed-off-by:

The vmx hardware state restore restores the tss selector and base address, but not its length. Usually, this does not matter since most of the tss contents is within the default length of 0x67. However, if a process is using ioperm() to grant itself I/O port permissions, an additional bitmap within the tss, but outside the default length is consulted. The effect is that the process will receive a SIGSEGV instead of transparently accessing the port. Fix by restoring the tss length. Note that i386 had this working already. Closes bugzilla 10246.

lockdep goes off on the iova copy_reserved_iova() because it and a function it calls grabs locks in the from, and the to of the copy operation. The function grab locks of the same lock classes triggering the warning. The first lock grabbed is for the constant reserved areas that is never accessed after early boot. Technically you could do without grabbing the locks for the "from" structure its copying reserved areas from. But dropping the from locks to me looks wrong, even though it would be ok. The affected code only runs in early boot as its setting up the DMAR engines. This patch gives the reserved_ioval_list locks special lockdep classes. Signed-off-by:

The VIA VT6212 defaults to only waiting 1us between passes over EHCI's async ring, which hammers PCI badly ... and by preventing other devices from accessing the bus, causes problems like drops in IDE throughput, a problem that's been bugging users of those chips for several years. A (partial) datasheet for this chip eventually turned up, letting us see how to make it use a VIA-specific register to switch over to the the normal 10us value instead, as suggested by the EHCI specification Solution noted by Lev A. Melnikovsky. It's not clear whether this register exists on other VIA chips; we know that it's ineffective on the vt8235. So this patch only applies to chips that seem to be incarnations of the (discrete) vt6212. Signed-off-by:

A Promise SATA controller will signal hotplug events when a hard reset (COMRESET) is done on a port. These events aren't masked by the driver, and the unexpected interrupts will cause a sequence of failed reset attempts util libata's EH finally gives up. This has not been a common problem so far, but the pending libata hardreset-by-default changes makes it a critical issue. The solution is to disable hotplug events before a reset, and to reenable them afterwards. (Promise's driver does this too.) This patch adds SATA-specific versions of ->freeze() and ->thaw() that also disable and enable hotplug events. PATA ports continue to use the old versions of ->freeze() and ->thaw(). Accesses to the hotplug register must be serialised via host->lock. We rely on ap->lock == &ap->host->lock and that libata takes this lock before ->freeze() and ->thaw(). Document this requirement. The interrupt handler is adjusted so its hotplug register accesses are inside the region protected by host->lock. Tested on various chips (SATA300TX4, SATA300TX2plus, SATAII150TX4, FastTrack TX4000) with various combinations of SATA and PATA disks, with and without the pending hardreset-by-default changes.

This is minor, but dereferencing even current real_parent is not safe on debug kernels, since the memory, this points to, can be unmapped - RCU protection is required. Besides, the tgid field is deprecated and is to be replaced with task_tgid_xxx call (the 2nd patch), so RCU will be required anyway. Signed-off-by:

Revert commit f1a9ee75: Author: Rik van Riel <riel@redhat.com> Date: Thu Feb 7 00:14:08 2008 -0800 kswapd should only wait on IO if there is IO The current kswapd (and try_to_free_pages) code has an oddity where the code will wait on IO, even if there is no IO in flight. This problem is notable especially when the system scans through many unfreeable pages, causing unnecessary stalls in the VM. Additionally, tasks without __GFP_FS or __GFP_IO in the direct reclaim path will sleep if a significant number of pages are encountered that should be written out. This gives kswapd a chance to write out those pages, while the direct reclaim task sleeps. Signed-off-by:

Update documentation for the hw_random support to be current: - Documentation/hw_random.txt has been updated to reflect the current code: it's a framework now, a "core" with a small sysfs interface, that hardware-specific drivers plug in to. Text specific to Intel hardware is now at the end. - Kconfig now references the Documentation/hw_random.txt file and better explains what this really does. Both chunks of documentation now higlight the fact that the kernel entropy pool is maintained by "rngd", and this driver has nothing directly to do with that important task. Signed-off-by:

Older smackfs was parsing MAC rules by characters, thus a need of locking write sessions on open() was needed. This lock is no longer useful now since each rule is handled by a single write() call. This is also a bugfix since seq_open() was not called if an open() O_RDWR flag was given, leading to a seq_read() without an initialized seq_file, thus an Oops. Signed-off-by:
