2011-06-29[SCSI] bnx2fc: Fix kernel panic when deleting NPIV portsBhanu Prakash Gollapudi
Deleting NPIV port causes a kernel panic when the NPIV port is in the same zone as the physical port and shares the same LUN. This happens due to the fact that vport destroy and unsolicited ELS are scheduled to run on the same workqueue, and vport destroy destroys the lport and the unsolicited ELS tries to access the invalid lport. This patch fixes this issue by maintaining a list of valid lports and verifying if the lport is valid or not before accessing it.

2011-06-28drm/i915: forcewake fix after resetBen Widawsky
The failure is as follows: 1. Userspace gets forcewake lock, lock count >=1 2. GPU hang/reset occurs (forcewake bit is reset) 3. count is now incorrect The failure can only occur when using the forcewake userspace lock. This has the unfortunate consequence of messing up the driver as well as userspace, unless userspace closes the debugfs file, the kernel will never end up waking the GT since the refcount will be > 1. The solution is to try to recover the correct forcewake state based on the refcount. There is a period of time where userspace reads/writes may occur after the reset, before the GT has been forcewaked. The interface was never designed to be a perfect solution for userspace reads/writes, and the kernel portion is fixed by this patch.

2011-06-28md: avoid endless recovery loop when waiting for fail device to complete.NeilBrown
If a device fails in a way that causes pending request to take a while to complete, md will not be able to immediately remove it from the array in remove_and_add_spares. It will then incorrectly look like a spare device and md will try to recover it even though it is failed. This leads to a recovery process starting and instantly aborting over and over again. We should check if the device is faulty before considering it to be a spare. This will avoid trying to start a recovery that cannot proceed. This bug was introduced in 2.6.26 so that patch is suitable for any kernel since then.

2011-06-27drm/i915: more struct_mutex lockingHugh Dickins
When auditing the locking in i915_gem.c (for a prospective change which I then abandoned), I noticed two places where struct_mutex is not held across GEM object manipulations that would usually require it. Since one is in initial setup and the other in driver unload, I'm guessing the mutex is not required for either; but post a patch in case it is.

2011-06-27drm/i915: use shmem_truncate_rangeHugh Dickins
The interface to ->truncate_range is changing very slightly: once "tmpfs: take control of its truncate_range" has been applied, this can be applied. For now there is only a slight inefficiency while this remains unapplied, but it will soon become essential for managing shmem's use of swap. Change i915_gem_object_truncate() to use shmem_truncate_range() directly: which should also spare i915 later change if we switch from inode_operations->truncate_range to file_operations->fallocate.

2011-06-27drm/i915: use shmem_read_mapping_pageHugh Dickins
Soon tmpfs will stop supporting ->readpage and read_cache_page_gfp(): once "tmpfs: add shmem_read_mapping_page_gfp" has been applied, this patch can be applied to ease the transition. Make i915_gem_object_get_pages_gtt() use shmem_read_mapping_page_gfp() in the one place it's needed; elsewhere use shmem_read_mapping_page(), with the mapping's gfp_mask properly initialized. Forget about __GFP_COLD: since tmpfs initializes its pages with memset, asking for a cold page is counter-productive. Include linux/shmem_fs.h also in drm_gem.c: with shmem_file_setup() now declared there too, we shall remove the prototype from linux/mm.h later.

2011-06-27Staging: comedi: fix build breakages on some platformsGreg Kroah-Hartman
Some platforms do not have virt_to_bus(), so properly depend on CONFIG_VIRT_TO_BUS for the Comedi drivers that need this function. Reported-by: Stephen Rothwell <sfr@canb.auug.org.au> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2011-06-27Staging: brcm80211: disable drivers except for X86 or MIPS platformsGreg Kroah-Hartman
As David points out, the driver is also broken on SPARC, so might as well just only enable it on platforms where people have reported it working, instead of trying to list all of the ones where it doesn't work, as the working platform list is much smaller...

2011-06-27Staging: brcm80211: disable drivers for PPC platformsGreg Kroah-Hartman
Right now, bad things happen if you try to build these drivers for the PPC platform as it seems that the code only has been tested and built on the MIPS big endian platform. So disable it on the PPC32 and PPC64 platforms for now, hopefully this will be resolved in the future as I'm sure someone will want to use these chips with that platform someday.

On architectures that don't define PAGE_KERNEL_NOCACHE, the Comedi driver turns into tragedy: CC [M] drivers/staging/comedi/drivers.o drivers/staging/comedi/drivers.c: In function ‘comedi_buf_alloc’: drivers/staging/comedi/drivers.c:505:41: error: ‘PAGE_KERNEL_NOCACHE’ undeclared (first use in this function) drivers/staging/comedi/drivers.c:505:41: note: each undeclared identifier is rep orted only once for each function it appears in make[3]: *** [drivers/staging/comedi/drivers.o] Error 1 Restrict the driver to only those architectures that define PAGE_KERNEL_NOCACHE. PAGE_KERNEL_NOCACHE is a kludge - some system architectures such as SGI IP27 are even uable to offer uncached operation - at least in the way an unwitting driver might assume. I haven't looked in details how the driver is using the area vmaped with PAGE_KERNEL_NOCACHE but maybe doing it XFS-style using cached memory and the flush_kernel_vmap_range / invalidate_kernel_vmap_range APIs in conjunction with the DMA API is a practical alternative.

Most HC implementations have selected to treat these registers as part of a 32-bit register, giving the same layout for both big and small endian systems. This patch adds a new quirk, big_endian_capbase, to support controllers with big endian register interfaces that treat HCIVERSION and CAPLENGTH as individual registers.
