2011-03-10drm/i915: Revive combination mode for backlight controlTakashi Iwai
This reverts commit 951f3512dba5bd44cda3e5ee22b4b522e4bb09fb drm/i915: Do not handle backlight combination mode specially since this commit introduced other regressions due to untouched LBPC register, e.g. the backlight dimmed after resume. In addition to the revert, this patch includes a fix for the original issue (weird backlight levels) by removing the wrong bit shift for computing the current backlight level. Also, including typo fixes (lpbc -> lbpc).

2011-03-08mmc: fix CONFIG_MMC_UNSAFE_RESUME regressionOhad Ben-Cohen
30201e7f3 ("mmc: skip detection of nonremovable cards on rescan") allowed skipping detection of nonremovable cards on mmc_rescan(). The intention was to only skip detection of hardwired cards that cannot be removed, so make sure this is indeed the case by directly checking for (lack of) MMC_CAP_NONREMOVABLE, instead of using mmc_card_is_removable(), which is overloaded with CONFIG_MMC_UNSAFE_RESUME semantics. The user-visible symptom of the bug this patch fixes is that no "mmc: card XXXX removed" message appears in dmesg when a card is removed and CONFIG_MMC_UNSAFE_RESUME=y.

2011-03-07drm/i915: Disable GPU semaphores by defaultChris Wilson
Andi Kleen narrowed his GPU hangs on his Sugar Bay (SNB desktop) rev 09 down to the use of GPU semaphores, and we already know that they appear broken up to Huron River (mobile) rev 08. (I'm optimistic that disabling GPU semaphores is simply hiding another bug by the latency and side-effects of the additional device interaction it introduces...) However, use of semaphores is a massive performance improvement... Only as long as the system remains stable. Enable at your peril.

2011-03-06virtio: console: Don't access vqs if device was unpluggedAmit Shah
If a virtio-console device gets unplugged while a port is open, a subsequent close() call on the port accesses vqs to free up buffers. This can lead to a crash. The buffers are already freed up as a result of the call to unplug_ports() from virtcons_remove(). The fix is to simply not access vq information if port->portdev is NULL.

2011-03-06drm/i915: Do not overflow the MMADDR write FIFOChris Wilson
Whilst the GT is powered down (rc6), writes to MMADDR are placed in a FIFO by the System Agent. This is a limited resource, only 64 entries, of which 20 are reserved for Display and PCH writes, and so we must take care not to queue up too many writes. To avoid this, there is counter which we can poll to ensure there are sufficient free entries in the fifo. "Issuing a write to a full FIFO is not supported; at worst it could result in corruption or a system hang."

2011-03-04pps: make pps_gen_parport depend on BROKENThomas Gleixner
This driver causes hard lockups, when the active clock soure is jiffies. The reason is that it loops with interrupts disabled waiting for a timestamp to be reached by polling getnstimeofday(). Though with a jiffies clocksource, when that code runs on the same CPU which is responsible for updating jiffies, then we loop in circles for ever simply because the timer interrupt cannot update jiffies. So both UP and SMP can be affected. There is no easy fix for that problem so make it depend on BROKEN for now.

2011-03-03[media] mantis_pci: remove asm/pgtable.h includeArnaud Patard (Rtp)
mantis_pci.c is including asm/pgtable.h and it's leading to a build failure on arm. It has been noticed here : https://buildd.debian.org/fetch.cgi?pkg=linux-2.6&arch=armel&ver=2.6.38~rc6-1~experimental.1&stamp=1298430952&file=log&as=raw As this header doesn't seem to be used, I'm removing it. I've build tested it with arm and x86. Signed-off-by: Arnaud Patard <arnaud.patard@rtp-net.org> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

2011-03-02cnic: Fix lost interrupt on bnx2xMichael Chan
We service 2 queues (kcq1 and kcq2) in cnic_service_bnx2x_bh(). If the status block index has changed when servicing the kcq2, we must go back and check kcq1. The latest status block index will be used to acknowledge the interrupt, and without looping back to check kcq1, we may miss events on kcq1.

2011-03-02of/promtree: allow DT device matching by fixing 'name' brokenness (v5)Andres Salomon
Commit e2f2a93b, "of/promtree: add package-to-path support to pdt" changed dp->name from using the 'name' property to using package-to-path. This fixed /proc/device-tree creation by eliminating conflicts between names (the 'name' property provides names like 'battery', whereas package-to-path provides names like '/foo/bar/battery@0', which we stripped to 'battery@0'). However, it also breaks of_device_id table matching. The fix that we _really_ wanted was to keep dp->name based upon the name property ('battery'), but based dp->full_name upon package-to-path ('battery@0'). This patch does just that. This changes all users (except SPARC) of promtree to use the full result from package-to-path for full_name, rather than stripping the directory out. In practice, the strings end up being exactly the same; this change saves time, code, and memory. SPARC continues to use the existing build_path_component() code. v2: combine two patches and revert of_pdt_node_name to original version v3: use dp->phandle instead of passing around node v4: warn/bail out for non-sparc archs if pkg2path is not set v5: split of_pdt_build_full_name into sparc & non-sparc versions v6: Pass NULL to pkg2path before buf gets assigned. Drop check for pkg2path hook on each and every node. v7: Don't BUG() when unable to get the full_path; create a known-unique name instead.

2011-03-02[media] tda829x: fix regression in probe functionsJarod Wilson
In commit 567aba0b7997dad5fe3fb4aeb174ee9018df8c5b, the probe address for tda8290_probe and tda8295_probe was hard-coded to 0x4b, which is the default i2c address for those devices, but its possible for the device to be at an alternate address, 0x42, which is the case for the HVR-1950. If we probe the wrong address, probe fails and we have a non-working device. We have the actual address passed into the function by way of i2c_props, we just need to use it. Also fix up some copy/paste comment issues and streamline debug spew a touch. Verified to restore my HVR-1950 to full working order. Special thanks to Ken Bass for reporting the issue in the first place, and to both he and Gary Buhrmaster for aiding in debugging and analysis of the problem.
