commit 5a882646 upstream. Similar to commit 7e59e097, this patch avoids unnecessary volume control indices for more Realtek auto-parsers, e g the ALC66x family, on the "Surround" and "Side" controls. These indices cause these volume controls to be ignored by PulseAudio and vmaster and should be removed whenever possible. Reported-by:

commit 60d97a84 upstream. The MUSB driver doesn't see its platform device on DM644x EVM board anymore since commit 73b089b0 (usb: musb: split davinci to its own platform_driver) because the new probe is called as subsys_initcall() now, and the device is registered later than that by the board code. Move the registration to davinci_evm_init() -- it's safe to do so because the MUSB core device still gets initialized as fs_initcall() -- which is late enough for the I2C GPIO expander (which controls VBUS) to be initialized.

commit 371c394a upstream. The latest binutils (2.21.0.20110302/Ubuntu) breaks the build yet another time, under CONFIG_XEN=y due to a .size directive that refers to a slightly differently named (hence, to the now very strict and unforgiving assembler, non-existent) symbol. [ mingo: This unnecessary build breakage caused by new binutils version 2.21 gets escallated back several kernel releases spanning several years of Linux history, affecting over 130,000 upstream kernel commits (!), on CONFIG_XEN=y 64-bit kernels (i.e. essentially affecting all major Linux distro kernel configs). Git annotate tells us that this slight debug symbol code mismatch bug has been introduced in 2008 in commit 3d75e1b8: 3d75e1b8 (Jeremy Fitzhardinge 2008-07-08 15:06:49 -0700 1231) ENTRY(xen_do_hypervisor_callback) # do_hypervisor_callback(struct *pt_regs) The 'bug' is just a slight assymetry in ENTRY()/END() debug-symbols sequences, with lots of assembly code between the ENTRY() and the END(): ENTRY(xen_do_hypervisor_callback) # do_hypervisor_callback(struct *pt_regs) ... END(do_hypervisor_callback) Human reviewers almost never catch such small mismatches, and binutils never even warned about it either. This new binutils version thus breaks the Xen build on all upstream kernels since v2.6.27, out of the blue. This makes a straightforward Git bisection of all 64-bit Xen-enabled kernels impossible on such binutils, for a bisection window of over hundred thousand historic commits. (!) This is a major fail on the side of binutils and binutils needs to turn this show-stopper build failure into a warning ASAP. ] Signed-off-by:

commit 0aab3995 upstream. During redetection of a SDIO card, a request for a new card RCA was submitted to the card, but was then overwritten by the old RCA. This caused the card to be deselected instead of selected when using the incorrect RCA. This bug's been present since the "oldcard" handling was introduced in 2.6.32. Signed-off-by:

commit 4981d01e upstream. According to intel CPU manual, every time PGD entry is changed in i386 PAE mode, we need do a full TLB flush. Current code follows this and there is comment for this too in the code. But current code misses the multi-threaded case. A changed page table might be used by several CPUs, every such CPU should flush TLB. Usually this isn't a problem, because we prepopulate all PGD entries at process fork. But when the process does munmap and follows new mmap, this issue will be triggered. When it happens, some CPUs keep doing page faults: http://marc.info/?l=linux-kernel&m=129915020508238&w=2 Reported-by: Yasunori Goto<y-goto@jp.fujitsu.com> Tested-by: Yasunori Goto<y-goto@jp.fujitsu.com> Reviewed-by:

commit 723aae25 upstream. Mike Galbraith reported finding a lockup ("perma-spin bug") where the cpumask passed to smp_call_function_many was cleared by other cpu(s) while a cpu was preparing its call_data block, resulting in no cpu to clear the last ref and unlock the block. Having cpus clear their bit asynchronously could be useful on a mask of cpus that might have a translation context, or cpus that need a push to complete an rcu window. Instead of adding a BUG_ON and requiring yet another cpumask copy, just detect the race and handle it. Note: arch_send_call_function_ipi_mask must still handle an empty cpumask because the data block is globally visible before the that arch callback is made. And (obviously) there are no guarantees to which cpus are notified if the mask is changed during the call; only cpus that were online and had their mask bit set during the whole call are guaranteed to be called.

commit 45a57919 upstream. Paul McKenney's review pointed out two problems with the barriers in the 2.6.38 update to the smp call function many code. First, a barrier that would force the func and info members of data to be visible before their consumption in the interrupt handler was missing. This can be solved by adding a smp_wmb between setting the func and info members and setting setting the cpumask; this will pair with the existing and required smp_rmb ordering the cpumask read before the read of refs. This placement avoids the need a second smp_rmb in the interrupt handler which would be executed on each of the N cpus executing the call request. (I was thinking this barrier was present but was not). Second, the previous write to refs (establishing the zero that we the interrupt handler was testing from all cpus) was performed by a third party cpu. This would invoke transitivity which, as a recient or concurrent addition to memory-barriers.txt now explicitly states, would require a full smp_mb(). However, we know the cpumask will only be set by one cpu (the data owner) and any preivous iteration of the mask would have cleared by the reading cpu. By redundantly writing refs to 0 on the owning cpu before the smp_wmb, the write to refs will follow the same path as the writes that set the cpumask, which in turn allows us to keep the barrier in the interrupt handler a smp_rmb instead of promoting it to a smp_mb (which will be be executed by N cpus for each of the possible M elements on the list). I moved and expanded the comment about our (ab)use of the rcu list primitives for the concurrent walk earlier into this function. I considered moving the first two paragraphs to the queue list head and lock, but felt it would have been too disconected from the code. Cc: Paul McKinney <paulmck@linux.vnet.ibm.com> Signed-off-by:

commit e6cd1e07 upstream. Peter pointed out there was nothing preventing the list_del_rcu in smp_call_function_interrupt from running before the list_add_rcu in smp_call_function_many. Fix this by not setting refs until we have gotten the lock for the list. Take advantage of the wmb in list_add_rcu to save an explicit additional one. I tried to force this race with a udelay before the lock & list_add and by mixing all 64 online cpus with just 3 random cpus in the mask, but was unsuccessful. Still, inspection shows a valid race, and the fix is a extension of the existing protection window in the current code. Reported-by:

commit 58d406ed upstream. Some versions of grep don't treat '\s' properly. When building perf on such systems and using a kernel tarball the perf version is unable to be determined from the main kernel Makefile and the user is left with a version of '..'. Replacing the use of '\s' with '[[:space:]]', which should work in all grep versions, gives a usable version number. Reported-by:

commit 87e3dc38 upstream. Some broken BIOSes on ICH4 chipset report an ACPI region which is in conflict with legacy IDE ports when ACPI is disabled. Even though the regions overlap, IDE ports are working correctly (we cannot find out the decoding rules on chipsets). So the only problem is the reported region itself, if we don't reserve the region in the quirk everything works as expected. This patch avoids reserving any quirk regions below PCIBIOS_MIN_IO which is 0x1000. Some regions might be (and are by a fast google query) below this border, but the only difference is that they won't be reserved anymore. They should still work though the same as before. The conflicts look like (1f.0 is bridge, 1f.1 is IDE ctrl): pci 0000:00:1f.1: address space collision: [io 0x0170-0x0177] conflicts with 0000:00:1f.0 [io 0x0100-0x017f] At 0x0100 a 128 bytes long ACPI region is reported in the quirk for ICH4. ata_piix then fails to find disks because the IDE legacy ports are zeroed: ata_piix 0000:00:1f.1: device not available (can't reserve [io 0x0000-0x0007]) References: https://bugzilla.novell.com/show_bug.cgi?id=558740Signed-off-by:
