This module is only selected by the rt2800pci driver if PCI support is enabled in the kernel, because some parts of the rt2x00pci code depends on PCI support.

Commit 70264367a243 ("ARM: 7653/2: do not scale loops_per_jiffy when using a constant delay clock") fixed a problem with our timer-based delay loop, where loops_per_jiffy is scaled by cpufreq yet used directly by the timer delay ops. This patch fixes the problem in a more elegant way by keeping a private ticks_per_jiffy field in the delay ops, independent of loops_per_jiffy and therefore not subject to scaling. The loop-based delay continues to use loops_per_jiffy directly, as it should.

init Commit b8db6b8 (ARM: 7547/4: cache-l2x0: add support for Aurora L2 cache ctrl) moved the masking of the part ID which caused the RTL version to be lost. Commit 6248d06 (ARM: 7545/1: cache-l2x0: make outer_cache_fns a field of l2x0_of_data) changed how .set_debug is initialized. Both commits break commit 74ddcdb (ARM: 7608/1: l2x0: Only set .set_debug on PL310 r3p0 and earlier) which uses the RTL version to conditionally set .set_debug function pointer. Commit b8db6b8 also caused the printed cache ID to be missing the version information. Fix this by reverting how the part number is masked so the RTL version info is maintained. The cache-id-part DT property does not set the RTL bits so masking them should have no effect. Also, re-arrange the order of the function pointer init so the .set_debug function can be overridden.

2013-04-03ALSA: usb: Work around CM6631 sample rate change bugTorstein Hegge
The C-Media CM6631 USB receiver doesn't respond to changes in sample rate while the interface is active. The same behavior is observed in other UAC2 hardware like the VIA VT1731. Reset the interface after setting the sampling frequency on sample rate changes, to ensure that the sample rate set by snd_usb_init_sample_rate() is used. Otherwise, the device will try to use the sample rate of the previous stream, causing distorted sound on sample rate changes. The reset is performed for all UAC2 devices, as it should not affect a standards compliant device, but it is only necessary for C-Media CM6631, VIA VT1731 and possibly others. Failure to read sample rate from the device is not handled as an error in set_sample_rate_v2(), as (permanent or intermittent) failure to read sample rate isn't essential for a successful sample rate set.

2013-04-03ACPI / BGRT: Don't let users configure BGRT on non X86 systemsTony Luck
Fengguang Wu's 0-Day kernel build testing backend found the following build error for an allmodconfig build on ia64: drivers/built-in.o: In function `show_yoffset': >> bgrt.c:(.text+0xe5a71): undefined reference to `bgrt_tab' >> bgrt.c:(.text+0xe5a91): undefined reference to `bgrt_tab' drivers/built-in.o: In function `show_xoffset': >> bgrt.c:(.text+0xe5b51): undefined reference to `bgrt_tab' >> bgrt.c:(.text+0xe5b71): undefined reference to `bgrt_tab' drivers/built-in.o: In function `show_type': >> bgrt.c:(.text+0xe5c31): undefined reference to `bgrt_tab' drivers/built-in.o:bgrt.c:(.text+0xe5c51): more undefined references to `bgrt_tab' follow drivers/built-in.o: In function `bgrt_init': bgrt.c:(.init.text+0x8931): undefined reference to `bgrt_image' bgrt.c:(.init.text+0x8932): undefined reference to `bgrt_image_size' bgrt.c:(.init.text+0x8950): undefined reference to `bgrt_image' bgrt.c:(.init.text+0x8960): undefined reference to `bgrt_image_size' The problem is that all these undefined names are provided by arch/x86/platform/efi/efi-bgrt.c - which is obviously not available to the ia64 build. It doesn't seem useful to provide the BGRT support for Itanium (many systems are headless and have no graphics at all). So just don't let users configure this driver on non-X86 machines.

The bitmask used for the prefix mangling was being calculated incorrectly, leading to the wrong part of the address being replaced when the prefix length wasn't a multiple of 32. Signed-off-by: Matthias Schiffer <mschiffer@universe-factory.net> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>

Pull networking fixes from David Miller: 1) Fix VSOCK layer handling of context ID changes, from Reilly Grant. 2) Now that we have a synchronize_net() in netdev_rx_handler_unregister(), we can't let any call sites hold locks. Unfortunately bonding does, so we have to drop the rwlock there a little bit earlier, fix from Veaceslav Falico. 3) MAC address setting loop exits one iteration too early in mlx4 driver, from Yan Burman. 4) Restore ipv6 routes properly upon ifdown/ifup of loopback, from Balakumaran Kannan. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: VSOCK: Handle changes to the VMCI context ID. net IPv6 : Fix broken IPv6 routing table after loopback down-up cbq: incorrect processing of high limits net/mlx4_en: Fix setting initial MAC address bonding: get netdev_rx_handler_unregister out of locks

2013-04-03ARM: mxs: Slow down the I2C clock speedMarek Vasut
Slow down the I2C clock speed on M28 and SPS1 as it turns out the I2C block in i.MX28 can not operate stable enough with the bus running at 400kHz. Note that the driver used by Freescale runs the bus at 250kHz when 400kHz speed is selected, but the mainline Linux kernel runs the bus at actual 400kHz and that's where it is occasionally unstable. Play safe and run the bus at 100kHz. Signed-off-by: Marek Vasut <marex@denx.de> Cc: Fabio Estevam <fabio.estevam@freescale.com> Signed-off-by: Shawn Guo <shawn.guo@linaro.org>
