2013-08-09powerpc: Rework setting up H/FSCR bit definitionsMichael Neuling
This reworks the Facility Status and Control Regsiter (FSCR) config bit definitions so that we can access the bit numbers. This is needed for a subsequent patch to fix the userspace DSCR handling. HFSCR and FSCR bit definitions are the same, so reuse them.

2013-08-09powerpc: Fix hypervisor facility unavaliable vector numberMichael Neuling
Currently if we take hypervisor facility unavaliable (from 0xf80/0x4f80) we mark it as an OS facility unavaliable (0xf60) as the two share the same code path. The becomes a problem in facility_unavailable_exception() as we aren't able to see the hypervisor facility unavailable exceptions. Below fixes this by duplication the required macros.

2013-08-09powerpc/pseries: Fix buffer overflow when reading from pstoreAruna Balakrishnaiah
When reading from pstore there is a buffer overflow during decompression due to the header added in unzip_oops. Remove unzip_oops and call pstore_decompress directly in nvram_pstore_read. Allocate buffer of size report_length of the oops header as header will not be deallocated in pstore.

2013-08-08ext4: fix mount/remount error messages for incompatible mount optionsPiotr Sarna
Commit 5688978 ("ext4: improve handling of conflicting mount options") introduced incorrect messages shown while choosing wrong mount options. First of all, both cases of incorrect mount options, "data=journal,delalloc" and "data=journal,dioread_nolock" result in the same error message. Secondly, the problem above isn't solved for remount option: the mismatched parameter is simply ignored. Moreover, ext4_msg states that remount with options "data=journal,delalloc" succeeded, which is not true. To fix it up, I added a simple check after parse_options() call to ensure that data=journal and delalloc/dioread_nolock parameters are not present at the same time.

2013-08-08hwmon: (adt7470) Fix incorrect return code checkCurt Brune
In adt7470_write_word_data(), which writes two bytes using i2c_smbus_write_byte_data(), the return codes are incorrectly AND-ed together when they should be OR-ed together. The return code of i2c_smbus_write_byte_data() is zero for success. The upshot is only the first byte was ever written to the hardware. The 2nd byte was never written out. I noticed that trying to set the fan speed limits was not working correctly on my system. Setting the fan speed limits is the only code that uses adt7470_write_word_data(). After making the change the limit settings work and the alarms work also.

2013-08-08Revert "slub: do not put a slab to cpu partial list when cpu_partial is 0"Linus Torvalds
This reverts commit 318df36e57c0ca9f2146660d41ff28e8650af423. This commit caused Steven Rostedt's hackbench runs to run out of memory due to a leak. As noted by Joonsoo Kim, it is buggy in the following scenario: "I guess, you may set 0 to all kmem caches's cpu_partial via sysfs, doesn't it? In this case, memory leak is possible in following case. Code flow of possible leak is follwing case. * in __slab_free() 1. (!new.inuse || !prior) && !was_frozen 2. !kmem_cache_debug && !prior 3. new.frozen = 1 4. after cmpxchg_double_slab, run the (!n) case with new.frozen=1 5. with this patch, put_cpu_partial() doesn't do anything, because this cache's cpu_partial is 0 6. return In step 5, leak occur" And Steven does indeed have cpu_partial set to 0 due to RT testing. Joonsoo is cooking up a patch, but everybody agrees that reverting this for now is the right thing to do.

2013-08-08ALSA: usb-audio: do not trust too-big wMaxPacketSize valuesClemens Ladisch
The driver used to assume that the streaming endpoint's wMaxPacketSize value would be an indication of how much data the endpoint expects or sends, and compute the number of packets per URB using this value. However, the Focusrite Scarlett 2i4 declares a value of 1024 bytes, while only about 88 or 44 bytes are be actually used. This discrepancy would result in URBs with far too few packets, which would not work correctly on the EHCI driver. To get correct URBs, use wMaxPacketSize only as an upper limit on the packet size.

2013-08-07arm64: KVM: fix 2-level page tables unmappingMarc Zyngier
When using 64kB pages, we only have two levels of page tables, meaning that PGD, PUD and PMD are fused. In this case, trying to refcount PUDs and PMDs independently is a a complete disaster, as they are the same. We manage to get it right for the allocation (stage2_set_pte uses {pmd,pud}_none), but the unmapping path clears both pud and pmd refcounts, which fails spectacularly with 2-level page tables. The fix is to avoid calling clear_pud_entry when both the pmd and pud pages are empty. For this, and instead of introducing another pud_empty function, consolidate both pte_empty and pmd_empty into page_empty (the code is actually identical) and use that to also test the validity of the pud.

2013-08-07drm/radeon/dpm: fix spread spectrum setup (v2)Alex Deucher
Need to check for engine and memory clock ss separately and only enable dynamic ss if either of them are found. This should fix systems which have a ss table, but do not have entries for engine or memory. On those systems we may enable dynamic spread spectrum without enabling it on the engine or memory clocks which can lead to a hang in some cases. fixes some systems reported here: https://bugs.freedesktop.org/show_bug.cgi?id=66963 v2: fix typo Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
2013-08-07drm/radeon/dpm: adjust thermal protection requirementsAlex Deucher
On rv770 and newer, clock gating is not required for thermal protection. The only requirement is that the design utilizes a thermal sensor. Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
2013-08-07drm/radeon: select audio dto based on encoder id for DCE3Alex Deucher
There are two audio dtos on radeon asics that you can select between. Normally, dto0 is used for hdmi and dto1 for DP, but it seems that the dto is somehow tied to the encoders on DCE3 asics. fixes: https://bugs.freedesktop.org/show_bug.cgi?id=67435 Signed-off-by: Alex Deucher <alexander.deucher@amd.com> Cc: stable@vger.kernel.org
2013-08-07drm/radeon: properly handle pm on gpu resetAlex Deucher
When we reset the GPU, we need to properly tear down power management before reseting the GPU and then set it back up again after reset. Add the missing radeon_pm_[suspend|resume] calls to the gpu reset function. Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
