2012-06-09mtd: nand: initialize bitflip_threshold prior to BBT scanningShmulik Ladkani
As of edbc454 [mtd: driver _read() returns max_bitflips; mtd_read() returns -EUCLEAN], 'mtd->bitflip_threshold' must be set for mtd devices having ECC, prior any 'mtd_read()' call. Otherwise, 'mtd_read()' will falsely return -EUCLEAN. Normally, 'mtd->bitflip_threshold' is initialized when the MTD is added. However, this is too late for NAND MTDs, as 'scan_bbt()' is invoked prior the existing initialization of 'mtd->bitflip_threshold'. This is a problem since 'scan_bbt()' calls 'mtd_read()', in the case of a flash-based bad block table. It resulted in a falsely reported bitflips indication during BBT read, which lead to constant scrubbing of the flash BBT blocks. Initialize 'mtd->bitflip_threshold' to its default value (if not already set by the driver), prior to invocation of 'scan_bbt()'.

2012-06-08Revert "drm/i915/crt: Do not rely upon the HPD presence pin"Linus Torvalds
This reverts commit 9e612a008fa7fe493a473454def56aa321479495. It incorrectly finds VGA connectors where none are attached, apparently not noticing that nothing replied to the EDID queries, and happily using the default EDID modes that have nothing to do with actual hardware. That in turn then causes X to fall down to the lowest common denominator, which is usually the default 1024x768 mode that is in the default EDID and pretty much anything supports). I'd suggest that if not relying on the HDP pin, the code should at least check whether it gets valid EDID data back, rather than just assume there's something on the VGA connector.

2012-06-08iwlwifi: don't mess up the SCD when removing a keyEmmanuel Grumbach
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.

Commit "aa44d1d UBI: remove Kconfig debugging option" broke UBI and it refuses to initialize if debugfs (CONFIG_DEBUG_FS) is disabled. I incorrectly assumed that debugfs files creation function will return success if debugfs is disabled, but they actually return -ENODEV. This patch fixes the issue.

With CONFIG_BLK_DEV_SD = n and CONFIG_PM = n, you get this compile failure: (.text+0x4f6c77): undefined reference to `scsi_sd_probe_domain' This was introduced by commit a7a20d103994fd760766e6c9d494daa569cbfe06 Author: Dan Williams <dan.j.williams@intel.com> Date: Thu Mar 22 17:05:11 2012 -0700 [SCSI] sd: limit the scope of the async probe domain And happens because scsi_sd_probe_domain is conditionally defined but unconditionally used.

Cougar/Panther Point redefine the bits in SDEIIR pretty completely. This function is just debugging, but if we're debugging we probably want to be told accurate things instead of lies. I'm told Lynx Point changes this yet more, but I have no idea how... Note from Eugeni's review: "For the record and for future enabling efforts, for LPT, bits 28-31 and 1-14 are gone since CPT/PPT (e.g., those must be zero). And there is the bit 15 as a new addition, but we are not using it yet and probably won't be using in foreseeable future."

git://git.kernel.org/pub/scm/linux/kernel/git/lenb/linux Pull ACPI and Power Management changes from Len Brown. This does an evil merge to fix up what I think is a mismerge by Len to the gma500 driver, and restore it to the mainline state. In that driver, both branches had commented out the call to acpi_video_register(), and Len resolved the merge to that commented-out version. However, in mainline, further changes by Alan (commit d839ede47a56: "gma500: opregion and ACPI" to be exact) had re-enabled the ACPI video registration, so the current state of the driver seems to want it. Alan is apparently still feeling the effects of partying with the Queen, so he didn't reply to my query, but I'll do the evil merge anyway. * 'release' of git://git.kernel.org/pub/scm/linux/kernel/git/lenb/linux: ACPI: fix acpi_bus.h build warnings when ACPI is not enabled drivers: acpi: Fix dependency for ACPI_HOTPLUG_CPU tools/power turbostat: fix IVB support tools/power turbostat: fix un-intended affinity of forked program ACPI video: use after input_unregister_device() gma500: don't register the ACPI video bus acpi_video: Intel video is not always i915 acpi_video: fix leaking PCI references ACPI: Ignore invalid _PSS entries, but use valid ones ACPI battery: only refresh the sysfs files when pertinent information changes

2012-06-06IB/mlx4: Fix max_wqe capacity reported from query deviceSagi Grimberg
1. Limit the max number of WQEs per QP reported when querying the device, so that ib_create_qp() will not fail for a QP size that the device claimed to support due to additional headroom WQEs being allocated. 2. Limit qp resources accepted for ib_create_qp() to the limits reported in ib_query_device(). In kernel space, make sure that the limits returned to the caller following qp creation also lie within the reported device limits. For userspace, report as before, and do adjustment in libmlx4 (so as not to break ABI).

2012-06-06mlx4_core: Fix setting VL_cap in mlx4_SET_PORT wrapper flowJack Morgenstein
Commit 096335b3f983 ("mlx4_core: Allow dynamic MTU configuration for IB ports") modifies the port VL setting. This exposes a bug in mlx4_common_set_port(), where the VL cap value passed in (inside the command mailbox) is incorrectly zeroed-out: mlx4_SET_PORT modifies the VL_cap field (byte 3 of the mailbox). Since the SET_PORT command is paravirtualized on the master as well as on the slaves, mlx4_SET_PORT_wrapper() is invoked on the master. This calls mlx4_common_set_port() where mailbox byte 3 gets overwritten by code which should only set a single bit in that byte (for the reset qkey counter flag) -- but instead overwrites the entire byte. The result is that when running in SR-IOV mode, the VL_cap will be set to zero -- fix this.
