2009-05-18UBI: remove redundant mutexArtem Bityutskiy
The @mult_mutex does not serve any purpose. We already have @volumes_mutex and it is enough. The @volume mutex is pushed down to the 'ubi_rename_volumes()', because we want first to open all volumes in the exclusive mode, and then lock the mutex, just like all other ioctl's (remove, re-size, etc) do.

2009-05-15libata: Media rotation rate and form factor heuristicsMartin K. Petersen
This patch provides new heuristics for parsing both the form factor and media rotation rate ATA IDENFITY words. The reported ATA version must be 7 or greater and the device must return values defined as valid in the standard. Only then are the characteristics reported to SCSI via the VPD B1 page. This seems like a reasonable compromise to me considering that we have been shipping several kernel releases that key off the rotation rate bit without any version checking whatsoever.

2009-05-15sysrq, intel_fb: fix sysrq g collisionJason Wessel
Commit 79e539453b34e35f39299a899d263b0a1f1670bd introduced a regression where you cannot use sysrq 'g' to enter kgdb. The solution is to move the intel fb sysrq over to V for video instead of G for graphics. The SMP VOYAGER code to register for the sysrq-v is not anywhere to be found in the mainline kernel, so the comments in the code were cleaned up as well. This patch also cleans up the sysrq definitions for kgdb to make it generic for the kernel debugger, such that the sysrq 'g' can be used in the future to enter a gdbstub or another kernel debugger.

2009-05-14drm/i915: ignore LVDS on intel graphics systems that lie about having itJarod Wilson
There are a number of small form factor desktop systems with Intel mobile graphics chips that lie and say they have an LVDS. With kernel mode-setting, this becomes a problem, and makes native resolution boot go haywire -- for example, my Dell Studio Hybrid, hooked to a 1920x1080 display claims to have a 1024x768 LVDS, and the resulting graphical boot on the 1920x1080 display uses only the top left 1024x768, and auto-configured X will end up only 1024x768 as well. With this change, graphical boot and X both do 1920x1080 as expected. Note that we're simply embracing and extending the early bail-out code in place for the Mac Mini here. The xorg intel driver uses pci subsystem device and vendor id for matching, while we're using dmi lookups here. The MSI addition is courtesy of and tested by Bill Nottingham.

2009-05-14drm/i915: sanity check IER at wait_request timeJesse Barnes
We might sleep here anyway so I hope an extra uncached read is ok to add. In #20896 we found that vbetool clobbers the IER. In KMS mode this is particularly bad since we don't set the interrupt regs late (in EnterVT), so we'd fail to get *any* interrupts at all after X started (since some distros have scripts that call vbetool at X startup apparently). So this patch checks IER at wait_request time, and re-enables interrupts if it's been clobbered. In a proper config this check should never be triggered. This is really a distro issue, but having a sanity check is nice, as long as it doesn't have a real performance hit.

This patch lets dma driver recognize if unmap_single or unmap_page should be used. It introduces two new dma control flags: DMA_COMPL_SRC_UNMAP_SINGLE and DMA_COMPL_DEST_UNMAP_SINGLE. They should be set to indicate dma driver to do dma-unmapping as single (first one for the source, tha latter for the destination).

This fixes a non-theoretical race condition when transmitting and receiving frames during a scan. If the channel or operating band changes while processing status descriptors in the tasklets, ath5k will incorrectly use the new channel and band when reporting the rates, even if the frame was actually sent on a previous channel. Typically this will manifest as a beacon found on an incorrect frequency and/or a warning in the driver while scanning: [ 4773.891944] cfg80211: Found new beacon on frequency: 5805 MHz (Ch 161) on phy0 [ 4785.461125] ------------[ cut here ]------------ [ 4785.461135] WARNING: at drivers/net/wireless/ath/ath5k/base.c:1141 ath5k_tasklet_rx+0x2ff/0x577 [ath5k]() [ 4785.461143] Hardware name: MacBook1,1 [ 4785.461148] invalid hw_rix: 1b [ 4785.461152] Modules linked in: fuse i915 drm af_packet acpi_cpufreq binfmt_misc dm_mirror dm_region_hash dm_log dm_multipath dm_mod arc4 ecb snd_hda_codec_idt snd_hda_intel snd_hda_codec snd_seq_dummy snd_seq_oss snd_seq_midi_event ath5k snd_seq hid_apple usbhid snd_seq_device mac80211 appletouch snd_pcm_oss sky2 ohci1394 snd_mixer_oss ath ieee1394 snd_pcm bitrev snd_timer cfg80211 crc32 snd snd_page_alloc button processor ac ehci_hcd joydev uhci_hcd sg battery thermal sr_mod cdrom applesmc evdev input_polldev unix [last unloaded: microcode] [ 4785.461296] Pid: 0, comm: swapper Tainted: G W 2.6.30-rc3-wl #112 [ 4785.461302] Call Trace: [ 4785.461316] [<c012590f>] warn_slowpath+0x76/0xa5 [ 4785.461331] [<c0219839>] ? debug_dma_unmap_page+0x5a/0x62 [ 4785.461357] [<f9982f88>] ath5k_tasklet_rx+0x2ff/0x577 [ath5k] [ 4785.461371] [<c01446f7>] ? trace_hardirqs_off+0xb/0xd [ 4785.461381] [<c0129928>] ? __tasklet_schedule+0x6e/0x7c [ 4785.461392] [<c0129b02>] tasklet_action+0x92/0xe5 [ 4785.461402] [<c0129f91>] __do_softirq+0xb1/0x182 [ 4785.461411] [<c012a092>] do_softirq+0x30/0x48 [ 4785.461428] [<c012a20a>] irq_exit+0x3d/0x74 [ 4785.461435] [<c035a0de>] do_IRQ+0x76/0x8c [ 4785.461440] [<c010312e>] common_interrupt+0x2e/0x34 [ 4785.461445] [<c014007b>] ? timer_list_show+0x1ab/0x939 [ 4785.461457] [<f85fd25c>] ? acpi_idle_enter_bm+0x27c/0x2b9 [processor] [ 4785.461463] [<c02d1ed6>] cpuidle_idle_call+0x6a/0x9c [ 4785.461468] [<c0101cc8>] cpu_idle+0x53/0x87 [ 4785.461473] [<c0346584>] rest_init+0x6c/0x6e [ 4785.461479] [<c04df74d>] start_kernel+0x286/0x28b [ 4785.461484] [<c04df037>] __init_begin+0x37/0x3c [ 4785.461487] ---[ end trace aaf8496ba3679dfb ]--- Signed-off-by: Bob Copeland <me@bobcopeland.com> Signed-off-by: John W.
