ARM: 7314/1: kuser: consistently use usr_ret for returning from helpers __kuser_cmpxchg64 has a return path using bx lr to get back to the caller. This is actually ok since the code in question is predicated on CONFIG_CPU_32v6K, but for the sake of consistency using the usr_ret macro is probably better.

rbd: fix safety of rbd_put_client() The rbd_client structure uses a kref to arrange for cleaning up and freeing an instance when its last reference is dropped. The cleanup routine is rbd_client_release(), and one of the things it does is delete the rbd_client from rbd_client_list. It acquires node_lock to do so, but the way it is done is still not safe. The problem is that when attempting to reuse an existing rbd_client, the stru…

Fix race in process_vm_rw_core This fixes the race in process_vm_core found by Oleg (see http://article.gmane.org/gmane.linux.kernel/1235667/ for details). This has been updated since I last sent it as the creation of the new mm_access() function did almost exactly the same thing as parts of the previous version of this patch did. In order to use mm_access() even when /proc isn't enabled, we move it to kernel/fork.c where…

ceph: create a new session lock to avoid lock inversion Lockdep was reporting a possible circular lock dependency in dentry_lease_is_valid(). That function needs to sample the session's s_cap_gen and and s_cap_ttl fields coherently, but needs to do so while holding a dentry lock. The s_cap_lock field was being used to protect the two fields, but that can't be taken while holding a lock on a dentry within the session. In most cases, the s_cap_gen and…

ceph: fix length validation in parse_reply_info() "len" is read from network and thus needs validation. Otherwise, given a bogus "len" value, p+len could be an out-of-bounds pointer, which is used in further parsing.

ceph: initialize client debugfs outside of monc->mutex Initializing debufs under monc->mutex introduces a lock dependency for sb->s_type->i_mutex_key, which (combined with several other dependencies) leads to an annoying lockdep warning. There's no particular reason to do the debugfs setup under this lock, so move it out. It used to be the case that our first monmap could come from the OSD; that is no longer the case with recent servers, so we will …

ceph: change "ceph.layout" xattr to be "ceph.file.layout" The virtual extended attribute named "ceph.layout" is meaningful only for regular files. Change its name to be "ceph.file.layout" to more directly reflect that in the ceph xattr namespace. Preserve the old "ceph.layout" name for the time being (until we decide it's safe to get rid of it entirely). Add a missing initializer for "readonly" in the terminating entry.

ARM: 7302/1: Add TLB flushing for both entries in a PMD Linux uses two PMD entries for a PTE with the classic page table format, covering 2MB range. However, the __pte_free_tlb() function only adds a single TLB flush corresponding to 1MB range covering 'addr'. On Cortex-A15, level 1 entries can be cached by the TLB independently of the level 2 entries and without additional flushing a PMD entry would be left pointing at the wrong PTE. The patch limits …

This was merged along with Cortex-A5 and Cortex-A15 PMU support, so they missed out on the original patch. This patch adds the empty definitions to Cortex-A5 and Cortex-A15.

ARM: 7308/1: vfp: flush thread hwstate before copying ptrace registers If we are context switched whilst copying into a thread's vfp_hard_struct then the partial copy may be corrupted by the VFP context switching code (see "ARM: vfp: flush thread hwstate before restoring context from sigframe"). This patch updates the ptrace VFP set code so that the thread state is flushed before the copy, therefore disabling VFP and preventing corruption from occurring. Cc: stable…

ARM: 7307/1: vfp: fix ptrace regset modification race In a preemptible kernel, vfp_set() can be preempted, causing the hardware VFP context to be switched while the thread vfp state is being read and modified. This leads to a race condition which can cause the thread vfp state to become corrupted if lazy VFP context save occurs due to preemption in between the time thread->vfpstate is read and the time the modified state is written back. This may o…

ARM: 7306/1: vfp: flush thread hwstate before restoring context from sigframe Following execution of a signal handler, we currently restore the VFP context from the ucontext in the signal frame. This involves copying from the user stack into the current thread's vfp_hard_struct and then flushing the new data out to the hardware registers. This is problematic when using a preemptible kernel because we could be context switched whilst updating the vfp_hard_struct. If the cur…

drm/radeon/kms/blit: fix blit copy for very large buffers Evergreen and NI blit copy was broken if the buffer maps to a rectangle whose one dimension is 16384 (max dimension allowed by these chips). In the mainline kernel, the problem is exposed only when buffers are very large (1G), but it's still a problem. The problem could be exposed for smaller buffers if anyone modifies the algorithm for rectangle construction in r600_blit_create_rect() (the reason…

ALSA: hda - Disable dynamic-power control for VIA as default Since the dynamic pin power-control and the analog low-current mode may lead to pop-noise, it's safer to set it off as default.

ALSA: hda - Allow analog low-current mode when dynamic power-control is on VIA codecs have several different power-saving features, and one of them is the analog low-current mode. But it turned out that the ALC mode causes pop-noises at each on/off time on some machines. As a quick workaround, disable the ALC when another power-saving feature, the dynamic pin power-control, is turned off, too, since the dynamic power-control is already exposed as a mixer enum element s…

ALSA: hda - Check power-state before changing in patch_via.c Instead of always writing AC_VERB_SET_POWER_STATE, check the current power-state and don't write again if the value is already set.
