Pull SCSI target fixes from Nicholas Bellinger: "Here are the outstanding target pending fixes for v3.12-rc7. This includes a number of EXTENDED_COPY related fixes as a result of Thomas and Doug's continuing testing and feedback. Also included is an important vhost/scsi fix that addresses a long standing issue where the 'write' parameter for get_user_pages_fast() was incorrectly set for virtio-scsi WRITEs -> DMA_TO_DEVICE, and not for virtio-scsi READs -> DMA_FROM_DEVICE. This resulted in random userspace segfaults and other unpleasantness on KVM host, and unfortunately has been an issue since the initial merge of vhost/scsi in v3.6. This patch is CC'ed to stable, along with two other less critical items" * git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending: vhost/scsi: Fix incorrect usage of get_user_pages_fast write parameter target/pscsi: fix return value check target: Fail XCOPY for non matching source + destination block_size target: Generate failure for XCOPY I/O with non-zero scsi_status target: Add missing XCOPY I/O operation sense_buffer iser-target: check device before dereferencing its variable target: Return an error for WRITE SAME with ANCHOR==1 target: Fix assignment of LUN in tracepoints target: Reject EXTENDED_COPY when emulate_3pc is disabled target: Allow non zero ListID in EXTENDED_COPY parameter list target: Make target_do_xcopy failures return INVALID_PARAMETER_LIST

2013-10-27parisc: Do not crash 64bit SMP kernels on machines with >= 4GB RAMHelge Deller
Since the beginning of the parisc-linux port, sometimes 64bit SMP kernels were not able to bring up other CPUs than the monarch CPU and instead crashed the kernel. The reason was unclear, esp. since it involved various machines (e.g. J5600, J6750 and SuperDome). Testing showed, that those crashes didn't happened when less than 4GB were installed, or if a 32bit Linux kernel was booted. In the end, the fix for those SMP problems is trivial: During the early phase of the initialization of the CPUs, including the monarch CPU, the PDC_PSW firmware function to enable WIDE (=64bit) mode is called. It's documented that this firmware function may clobber various registers, and one one of those possibly clobbered registers is %cr30 which holds the task thread info pointer. Now, if %cr30 would always have been clobbered, then this bug would have been detected much earlier. But lots of testing finally showed, that - at least for %cr30 - on some machines only the upper 32bits of the 64bit register suddenly turned zero after the firmware call. So, after finding the root cause, the explanation for the various crashes became clear: - On 32bit SMP Linux kernels all upper 32bit were zero, so we didn't faced this problem. - Monarch CPUs in 64bit mode always booted sucessfully, because the inital task thread info pointer was below 4GB. - Secondary CPUs booted sucessfully on machines with less than 4GB RAM because the upper 32bit were zero anyay. - Secondary CPus failed to boot if we had more than 4GB RAM and the task thread info pointer was located above the 4GB boundary. Finally, the patch to fix this problem is trivial by saving the %cr30 register before the firmware call and restoring it afterwards.

2013-10-26staging/lustre/llite: fix mkdir endless loopPeng Tao
Running on 3.11-rc4 kernel, I got below endless loop. It turns to be that Lustre always saves the first page of a dir inode mapping at index ~0UL. And after commit 5a720394 (mm: teach truncate_inode_pages_range() to handle non page aligned ranges), truncate_inode_pages_range() _NO LONGER_ truncates the page that is sitting at index ~0UL.
