[PATCH 01/26] cciss: Set the performant mode bit in the scsi half of the driver
From: Stephen M. Cameron <scameron(a)beardog.cce.hp.com> cciss: Set the performant mode bit in the scsi half of the driver In a couple of places, the performant mode bit wasn't being set in the scsi half of the driver, causing commands to seem to hang. Use enqueue_cmd_and_start_io() where appropriate. This fixes ... 19 Jul 2010 15:46

[patch 2/3] x86: sync xsave memory layout with its header for user handling
With xsaveopt, if a processor implementation discern that a processor state component is in its initialized state it may modify the corresponding bit in the xsave_hdr.xstate_bv as '0', with out modifying the corresponding memory layout. Hence wHile presenting the xstate information to the user, we always ensure tha... 19 Jul 2010 15:46

[patch 0/3] x86: xsaveopt kernel enabling patches
AVX Programming Reference (June, 2010 version) located at http://software.intel.com/en-us/avx/ refers to the optimized extended state save instruction "xsaveopt". xsaveopt is similar to xsave and incorporates optimizations specifically targeted for speeding up context switch save, like: a. if a state is in an IN... 19 Jul 2010 15:46

[patch 1/3] x86: track the offset, size of features state in the xsave layout
Subleaves of the cpuid vector 0xd provides the offset and size of different feature state that are managed by the xsave/xrstor. Track this for the upcoming usage during signal handling.

[patch 3/3] x86: use xsaveopt in context-switch path when supported
xsaveopt is a more optimized form of xsave specifically designed for the context switch usage. xsaveopt doesn't save the state that's not modified from the prior xrstor. And if a specific feature state gets modified to the init state, then xsaveopt just updates the header bit in the xsave memory layout without upda... 19 Jul 2010 15:46

[PATCH 00/26] cciss updates July 19, 2010
The following series implements mostly cleanups to the initialization code in cciss along the same lines as what's already been done in hpsa. There are also a few bug fixes. The SCSI tape code was not setting the performant mode bits in commands, which caused a hang. The code to reset controllers via PCI power ... 19 Jul 2010 15:46

[patch] usbnet: fix 100% CPU use on suspended device
From: Elly Jones <ellyjones(a)google.com> This patch causes the usbnet module not to attempt to submit URBs to the device if the device is not ready to accept them. This fixes a misbehavior trigged by the Qualcomm Gobi driver (released under GPL through their Code Aurora initiative) which causes the usbnet core to ... 19 Jul 2010 14:39
