git://git.kernel.org/pub/scm/linux/kernel/git/swarren/linux-tegra into next/cleanup From Stephen Warren <swarren@wwwdotorg.org>: ARM: tegra: cleanup This branch includes various cleanup of the core Tegra support. * Unification of the separate board-dt-tegra*.c files into a single tegra.c, now that everything is DT-driven and basically identical. * Use of_clk_get() in the Tegra clocksource driver so that clocks are described in DT rather than hard-coding clock names. * Some cleanup of the PMC-related code, with the aim that the PMC "driver" contains more of the code that touches PMC registers, rather than spreading PMC register accesses through other files. * Conversion of the "PMC" driver to acquire resources describe in device tree rather than hard-coding them. * Use of common code for the CPU sleep TLB invalidation.

2013-04-05ARM: OMAP4+: PM: Restore CPU power state to ON with clockdomain force wakeup ↵Santosh Shilimkar
method While waking up CPU from off state using clock domain force wakeup, restore the CPU power state to ON state before putting CPU clock domain under hardware control. Otherwise CPU wakeup might fail. The change is recommended for all OMAP4+ devices though the PRCM weakness was observed on OMAP5 devices first. As a result of weakness, lock-up is observed inside the hardware state machine of local CPU PRCM and results are UN-predictable as per designers. In software testing, we have seen hard-locks most of the time where system gets frozen. With power domain state restored, system behaves correctly. So update the code accordingly.

2013-03-29rbd: don't zero-fill non-image object requestsAlex Elder
A result of ENOENT from a read request for an object that's part of an rbd image indicates that there is a hole in that portion of the image. Similarly, a short read for such an object indicates that the remainder of the read should be interpreted a full read with zeros filling out the end of the request. This behavior is not correct for objects that are not backing rbd image data. Currently rbd_img_obj_request_callback() assumes it should be done for all objects. Change rbd_img_obj_request_callback() so it only does this zeroing for image objects. Encapsulate that special handling in its own function. Add an assertion that the image object request is a bio request, since we assume that (and we currently don't support any other types). This resolves a problem identified here: http://tracker.ceph.com/issues/4559 The regression was introduced by bf0d5f503dc11d6314c0503591d258d60ee9c944.

2013-03-28target: Fix RESERVATION_CONFLICT status regression for iscsi-target special caseNicholas Bellinger
This patch fixes a regression introduced in v3.8-rc1 code where a failed target_check_reservation() check in target_setup_cmd_from_cdb() was causing an incorrect SAM_STAT_GOOD status to be returned during a WRITE operation performed by an unregistered / unreserved iscsi initiator port. This regression is only effecting iscsi-target due to a special case check for TCM_RESERVATION_CONFLICT within iscsi_target_erl1.c:iscsit_execute_cmd(), and was still correctly disallowing WRITE commands from backend submission for unregistered / unreserved initiator ports, while returning the incorrect SAM_STAT_GOOD status due to the missing SAM_STAT_RESERVATION_CONFLICT assignment. This regression was first introduced with: commit de103c93aff0bed0ae984274e5dc8b95899badab Author: Christoph Hellwig <hch@lst.de> Date: Tue Nov 6 12:24:09 2012 -0800 target: pass sense_reason as a return value Go ahead and re-add the missing SAM_STAT_RESERVATION_CONFLICT assignment during a target_check_reservation() failure, so that iscsi-target code sends the correct SCSI status.

programs" This reverts commit 186930500985 ("mm: introduce VM_POPULATE flag to better deal with racy userspace programs"). VM_POPULATE only has any effect when userspace plays racy games with vmas by trying to unmap and remap memory regions that mmap or mlock are operating on. Also, the only effect of VM_POPULATE when userspace plays such games is that it avoids populating new memory regions that get remapped into the address range that was being operated on by the original mmap or mlock calls. Let's remove VM_POPULATE as there isn't any strong argument to mandate a new vm_flag.

2013-03-28Btrfs: fix wrong return value of btrfs_lookup_csum()Miao Xie
If we don't find the expected csum item, but find a csum item which is adjacent to the specified extent, we should return -EFBIG, or we should return -ENOENT. But btrfs_lookup_csum() return -EFBIG even the csum item is not adjacent to the specified extent. Fix it.

2013-03-28Btrfs: fix wrong reservation of csumsMiao Xie
We reserve the space for csums only when we write data into a file, in the other cases, such as tree log, log replay, we don't do reservation, so we can use the reservation of the transaction handle just for the former. And for the latter, we should use the tree's own reservation. But the function - btrfs_csum_file_blocks() didn't differentiate between these two types of the cases, fix it.

2013-03-28Btrfs: fix double free in the btrfs_qgroup_account_ref()Wang Shilong
The function btrfs_find_all_roots is responsible to allocate memory for 'roots' and free it if errors happen,so the caller should not free it again since the work has been done. Besides,'tmp' is allocated after the function btrfs_find_all_roots, so we can return directly if btrfs_find_all_roots() fails.

2013-03-28Btrfs: limit the global reserve to 512mbJosef Bacik
A user reported a problem where he was getting early ENOSPC with hundreds of gigs of free data space and 6 gigs of free metadata space. This is because the global block reserve was taking up the entire free metadata space. This is ridiculous, we have infrastructure in place to throttle if we start using too much of the global reserve, so instead of letting it get this huge just limit it to 512mb so that users can still get work done. This allowed the user to complete his rsync without issues.
