66832eb perf: Validate cpu early in perf_event_alloc() Starting from perf_event_alloc()->perf_init_event(), the kernel assumes that event->cpu is either -1 or the valid CPU number. Change perf_event_alloc() to validate this argument early. This also means we can remove the similar check in find_get_context().

22a4ec7 perf: Find_get_context: fix the per-cpu-counter check If task == NULL, find_get_context() should always check that cpu is correct. Afaics, the bug was introduced by 38a81da2 "perf events: Clean up pid passing", but even before that commit "&& cpu != -1" was not exactly right, -ESRCH from find_task_by_vpid() is not accurate.

79aa18d MIPS: Malta: enable Cirrus FB console While most users of a physical Malta board are using the serial port as the console, a lot of QEMU users would prefer to interact with a graphical console. Enable the Cirrus FB support in the Malta default configuration to make that possible. Note that the default console will still be the serial port, users have to pass "console=tty0" to the kernel to use the Cirrus FB.

1befdd5 MIPS: Implement __read_mostly Just do what everyone else is doing by placing __read_mostly things in the .data.read_mostly section. mips_io_port_base can not be read-only (const) and writable (__read_mostly) at the same time. One of them has to go, so I chose to eliminate the __read_mostly. It will still get stuck in a portion of memory that is not adjacent to things that are written, and thus not be on a dirty cache line, for whatever that is worth.

d4a67d9 MIPS: Add initial support for the Atheros AR71XX/AR724X/AR931X SoCs This patch adds initial support for various Atheros SoCs based on the MIPS 24Kc core. The following models are supported at the moment: - AR7130 - AR7141 - AR7161 - AR9130 - AR9132 - AR7240 - AR7241 - AR7242 The current patch contains minimal support only, but the resulting kernel can boot into user-space with using of an initramfs image on various boards which are using these SoCs. Support for more built-in devices and individual boards will be implemented in further patches.

8d662c8 MIPS: Use WARN() in uasm for better diagnostics. On the off chance that uasm ever warns about overflow, there is no way to know what the offending instruction is.

Going over the code I cannot convince myself its correct: - holding a ref on the parent_ctx, doesn't avoid it being uncloned concurrently (as the comment says), so we can race with a free. - holding parent_ctx->mutex doesn't avoid the above free from taking place either, it would at best avoid parent_ctx from being freed. I.e. the warning is correct. To fix the bug, serialize against the unclone_ctx() call by extending the reach of the parent_ctx->lock.

86b1e8d x86: Make relocatable kernel work with new binutils The CONFIG_RELOCATABLE=y option is broken with new binutils, which will make boot panic. According to Lu Hongjiu, the affected binutils are from 2.20.51.0.12 to 2.21.51.0.3, which are release since Oct 22 this year. At least ubuntu 10.10 is using such binutils. See: http://sourceware.org/bugzilla/show_bug.cgi?id=12327 The reason of the boot panic is that we have 'jiffies = jiffies_64;' in vmlinux.lds.S. The jiffies isn't in any section. In kernel build, there is warning saying jiffies is an absolute address and can't be relocatable. At runtime, jiffies will have virtual address 0.

Further down, at the current dentry check for it being simple_positive() it looks like the d_lock for dentry p should be dropped instead of dentry ret, otherwise when p is assinged to ret we end up with no lock on p and a lost lock on ret, which leads to a deadlock.

acce952 Btrfs: forced readonly mounts on errors This patch comes from "Forced readonly mounts on errors" ideas. As we know, this is the first step in being more fault tolerant of disk corruptions instead of just using BUG() statements. The major content: - add a framework for generating errors that should result in filesystems going readonly. - keep FS state in disk super block. - make sure that all of resource will be freed and released at umount time. - make sure that fter FS is forced readonly on error, there will be no more disk change before FS is corrected. For this, we should stop write operation. After this patch is applied, the conversion from BUG() to such a framework can happen incrementally.

154bf89 mtd: mtdpart: disallow reading OOB past the end of the partition This patch fixes the mtdpart bug which allows users reading OOB past the end of the partition. This happens because 'part_read_oob()' allows reading multiple OOB areas in one go, and mtdparts does not validate the OOB length in the request. Although there is such check in 'nand_do_read_oob()' in nand_base.c, but it checks that we do not read past the flash chip, not the partition, because in nand_base.c we work with the whole chip (e.g., mtd->size in nand_base.c is the size of the whole chip). So this check cannot be done correctly in nand_base.c and should be instead done in mtdparts.c. This problem was reported by Jason Liu <r64343@freescale.com> and reproduced with nandsim: $ modprobe nandsim first_id_byte=0x20 second_id_byte=0xaa third_id_byte=0x00 \ fourth_id_byte=0x15 parts=0x400,0x400 $ modprobe nandsim mtd_oobtest.ko dev=0 $ dmesg = snip = mtd_oobtest: attempting to read past end of device mtd_oobtest: an error is expected... mtd_oobtest: error: read past end of device = snip = mtd_oobtest: finished with 2 errors Reported-by: Jason Liu <liu.h.jason@gmail.com> Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com> Signed-off-by: David Woodhouse <David.Woodhouse@intel.com> 17 January 2011, 15:25:48 UTC
7322ce2 ASoC: EP93xx: fixed LRCLK rate and DMA oper. in I2S code Changelog: 1. I2S module of EP93xx should be feed by 32bit DMA transfers. This is hardware limitation and that's the way original Cirrus's driver worked. This will fix distorted sound playback and make capture actually work in present ep93xx drivers. I've found, that author of code, on which modern ep93xx-i2s.c and ep93xx-pcm.c are based, had faced this problem also in 2007: http://blog.gmane.org/gmane.linux.ports.arm.cirrus/month=20070101/page=3 Now SoC code uses his developments, but not overcomes the hardware issues. Some details from EP93xx users guide: Both I2S transmitter and receiver have similar 16x32bit FIFO, where they store 8 samples for both left and right channels. The FIFO is always 32bit wide and should be properly aligned if you use samples of other width. Transmitter and receiver have configuration registers for selection of I2S word length (16, 24, 32). They are I2STXWrdLen and I2SRXWrdLen. Yes, EP93xx DMA can do byte, word and quad-word transfers. The width for transfers to and from peripherals is selected by particular module configuration. Lucky AC97 module has such configuration: AC97RXCRx registers, bit CM (Compact mode enable) switches between 16 and 32 bit samples. AC97TXCRx registers have the same bits for transmitters. ep93xx-ac97.c enables this compact mode and so has all the rights to use S16_LE format. No one has found such a configuration in I2S module until now in any Cirrus manuals. I2S module always feeds it's 32bit wide FIFO with 32bit samples consecutively for left and right channels. You cannot use 32-bit DMA transfers to transfer two 16-bit samples. So we can use two formats for AC97, but should remove all but S32_LE for I2S. Always using 32 bit chunks is not a problem for I2S, the codec I use uses less bits too (24), it's permitted by I2S standard. In proposed patch formats list shortened to just S32_LE, this makes all the DMA transactions right, while ALSA will do all sample format translation for us. 2. Incorrect setting of LRCLK (2 times slower) in original ep93xx-i2s.c masks the first problem. DMA takes two 16 bit samples instead of one, overall sound speed seems to be normal, but you get actually 4000 sampling rate instead of requested 8000 and therefore some noise... This is also the reason why the capture function not worked at all in this driver... If we take a look into I2S specification, we will figure that LRCLK MUST be equal to sample rate, if we are talking about stereo (in mono too, but it's not our case at all). In proposed patch SCLK and LRCLK rates are corrected, assuming we always send 32 bits * 2 channels to codec.

4bca770 powerpc: perf: Fix frequency calculation for overflowing counters When profiling a benchmark that is almost 100% userspace, I noticed some wildly inaccurate profiles that showed almost all time spent in the kernel. Closer examination shows we were programming a tiny number of cycles into the PMU after each overflow (about ~200 away from the next overflow). This gets us stuck in a loop which we eventually break out of by throttling the PMU (there are regular throttle/unthrottle events in the log). It looks like we aren't setting event->hw.last_period to something same and the frequency to period calculations in perf are going haywire. With the following patch we find the correct period after a few interrupts and stay there. I also see no more throttle events.
