commit e652f4c8 upstream. A few machines with ALC861 & co are reported not to work properly with the auto-mute feature in software. The auto-mute feature is implemented in the hardware level, and the jack-detection never works with them. Also, rename the fixup index as ALC861_FIXUP_* to follow the standard. Signed-off-by:

commit d2c8b15d upstream. My patch iwlwifi: use correct released ucode version did not correctly report supported firmware for the 6035 device. This patch fixes it. The minimum supported firmware version for 6035 is v6. Also correct the minimum supported firmware version for the 6000g2 series of devices. Signed-off-by:

commit 2d0dbc6a upstream. While nfs4_do_open() expects the fmode argument to be restricted to combinations of FMODE_READ and FMODE_WRITE, both nfs4_atomic_open() and nfs4_proc_create will pass the nfs_open_context->mode, which contains the full fmode_t. This patch ensures that nfs4_do_open strips the other fmode_t bits, fixing a problem in which the nfs4_do_open call would result in an unnecessary delegation return. Reported-by:

commit 350ab15b upstream. The statically defined I/O memory regions for the i.MX21 on chip peripherals and the on board I/O peripherals of the i.MX21ADS board overlap. This results in a kernel crash during startup. This is fixed by reducing the memory range for the on board I/O peripherals to the actually required range. Signed-off-by:

commit 602bf409 upstream. There is a system hang issue on imx6q which can easily be seen with running a cpu hotplug stress testing (hotplug secondary cores from user space via sysfs interface for thousands iterations). It turns out that the issue is caused by coherency of the cpu that is being shut down. When shutting down a cpu, we need to have the cpu exit coherency to prevent it from receiving cache, TLB, or BTB maintenance operations broadcast by other CPUs in the cluster. Copy cpu_enter_lowpower() and cpu_leave_lowpower() from mach-vexpress to have coherency properly handled in platform_cpu_die(), thus fix the issue. Signed-off-by:

commit 71ecfa18 upstream. When any interface goes down, it could be the one that we were doing a remain-on-channel with. We therefore need to cancel the remain-on-channel and flush the related work structs so they don't run after the interface has been removed or even destroyed. It's also possible in this case that an off-channel SKB was never transmitted, so free it if this is the case. Note that this can also happen if the driver finishes the off-channel period without ever starting it. Reported-by:

commit f461f27a upstream. Fix the issue of C_CAN interrupts getting disabled forever when canconfig utility is used multiple times. According to NAPI usage we disable all the hardware interrupts in ISR and re-enable them in poll(). Current implementation calls napi_enable() after hardware interrupts are enabled. If we get any interrupts between these two steps then we do not process those interrupts because napi is not enabled. Mostly these interrupts come because of STATUS is not 0x7 or ERROR interrupts. If napi_enable() happens before HW interrupts enabled then c_can_poll() function will be called eventual re-enabling. This patch moves the napi_enable() call before interrupts enabled. Signed-off-by:

commit 148c87c8 upstream. This patch fixes an interrupt thrash issue with c_can driver. In c_can_isr() function interrupts are disabled and enabled only in c_can_poll() function. c_can_isr() & c_can_poll() both read the irqstatus flag. However, irqstatus is always read as 0 in c_can_poll() because all C_CAN interrupts are disabled in c_can_isr(). This causes all interrupts to be re-enabled in c_can_poll() which in turn causes another interrupt since the event is not really handled. This keeps happening causing a flood of interrupts. To fix this, read the irqstatus register in isr and use the same cached value in the poll function. Signed-off-by:

commit 617cacce upstream. This patch fixes an issue with transmit routine, which causes "can_put_echo_skb: BUG! echo_skb is occupied!" message when using "cansequence -p" on D_CAN controller. In c_can driver, while transmitting packets tx_echo flag holds the no of can frames put for transmission into the hardware. As the comment above c_can_do_tx() indicates, if we find any packet which is not transmitted then we should stop looking for more. In the current implementation this is not taken care of causing the said message. Also, fix the condition used to find if the packet is transmitted or not. Current code skips the first tx message object and ends up checking one extra invalid object. While at it, fix the comment on top of c_can_do_tx() to use the terminology "packet" instead of "package" since it is more standard. Signed-off-by:

commit 5e626254 upstream. Xen PV kernels allow access to the APERF/MPERF registers to read the effective frequency. Access to the MSRs is however redirected to the currently scheduled physical CPU, making consecutive read and compares unreliable. In addition each rdmsr traps into the hypervisor. So to avoid bogus readouts and expensive traps, disable the kernel internal feature flag for APERF/MPERF if running under Xen. This will a) remove the aperfmperf flag from /proc/cpuinfo b) not mislead the power scheduler (arch/x86/kernel/cpu/sched.c) to use the feature to improve scheduling (by default disabled) c) not mislead the cpufreq driver to use the MSRs This does not cover userland programs which access the MSRs via the device file interface, but this will be addressed separately.

commit d6ee27eb upstream. When we remove a key, we put a key index which was supposed to tell the fw that we are actually removing the key. But instead the fw took that index as a valid index and messed up the SRAM of the device. This memory corruption on the device mangled the data of the SCD. The impact on the user is that SCD queue 2 got stuck after having removed keys. The message is the log that was printed is: Queue 2 stuck for 10000ms This doesn't seem to fix the higher queues that get stuck from time to time. Reviewed-by:

commit a841f8ce upstream. It does not get processed because sched_domain_level_max is 0 at the time that setup_relax_domain_level() is run. Simply accept the value as it is, as we don't know the value of sched_domain_level_max until sched domain construction is completed. Fix sched_relax_domain_level in cpuset. The build_sched_domain() routine calls the set_domain_attribute() routine prior to setting the sd->level, however, the set_domain_attribute() routine relies on the sd->level to decide whether idle load balancing will be off/on.

BIOS will switch off the corresponding feature flag on family 15h models 10h-1fh non-desktop CPUs. The topology extension CPUID leafs are required to detect which cores belong to the same compute unit. (thread siblings mask is set accordingly and also correct information about L1i and L2 cache sharing depends on this). W/o this patch we wouldn't see which cores belong to the same compute unit and also cache sharing information for L1i and L2 would be incorrect on such systems. Signed-off-by:

commit f227d430 upstream. Currently, the APIC LVT interrupt for error thresholding is implicitly enabled. However, there are models in the F15h range which do not enable it. Make the code machinery which sets up the APIC interrupt support an optional setting and add an ->interrupt_capable member to the bank representation mirroring that capability and enable the interrupt offset programming only if it is true. Simplify code and fixup comment style while at it. This patch is for stable kernels v3.0 to v3.2. Signed-off-by:

commit 45c72cd7 upstream. Now we store attr->ino at inode->i_ino, return attr->ino at the first time and then return inode->i_ino if the attribute timeout isn't expired. That's wrong on 32 bit platforms because attr->ino is 64 bit and inode->i_ino is 32 bit in this case. Fix this by saving 64 bit ino in fuse_inode structure and returning it every time we call getattr. Also squash attr->ino into inode->i_ino explicitly. Signed-off-by:

commit 3c752965 upstream. This fixes a problem which can causes kernel oopses while loading a kernel module. According to the PowerPC EABI specification, GPR r11 is assigned the dedicated function to point to the previous stack frame. In the powerpc-specific kernel module loader, do_plt_call() (in arch/powerpc/kernel/module_32.c), GPR r11 is also used to generate trampoline code. This combination crashes the kernel, in the case where the compiler chooses to use a helper function for saving GPRs on entry, and the module loader has placed the .init.text section far away from the .text section, meaning that it has to generate a trampoline for functions in the .init.text section to call the GPR save helper. Because the trampoline trashes r11, references to the stack frame using r11 can cause an oops. The fix just uses GPR r12 instead of GPR r11 for generating the trampoline code. According to the statements from Freescale, this is safe from an EABI perspective. I've tested the fix for kernel 2.6.33 on MPC8541. Signed-off-by:

commit d5d2d2ee upstream. The SGI Altix UV2 BAU (Broadcast Assist Unit) as used for tlb-shootdown (selective broadcast mode) always uses UV2 broadcast descriptor format. There is no need to clear the 'legacy' (UV1) mode, because the hardware always uses UV2 mode for selective broadcast. But the BIOS uses general broadcast and legacy mode, and the hardware pays attention to the legacy mode bit for general broadcast. So the kernel must not clear that mode bit. Signed-off-by:

commit cb05d8de upstream. Or at least plug another gapping hole. Apparrently hw desingers only moved the bit field, but did not bother ot re-enumerate the planes when adding support for a 3rd pipe. Discovered by i-g-t/flip_test. This may or may not fix the reference bugzilla, because that one smells like we have still larger fish to fry. v2: Fixup the impossible case to catch programming errors, noticed by Chris Wilson.
