2012-11-02hashtable: introduce a small and naive hashtableSasha Levin1-0/+192
This hashtable implementation is using hlist buckets to provide a simple hashtable to prevent it from getting reimplemented all over the kernel.

2012-11-01KVM: x86: fix vcpu->mmio_fragments overflowXiao Guangrong1-13/+2
After commit b3356bf0dbb349 (KVM: emulator: optimize "rep ins" handling), the pieces of io data can be collected and write them to the guest memory or MMIO together Unfortunately, kvm splits the mmio access into 8 bytes and store them to vcpu->mmio_fragments. If the guest uses "rep ins" to move large data, it will cause vcpu->mmio_fragments overflow The bug can be exposed by isapc (-M isapc): [23154.818733] general protection fault: 0000 [#1] SMP DEBUG_PAGEALLOC [ ......] [23154.858083] Call Trace: [23154.859874] [<ffffffffa04f0e17>] kvm_get_cr8+0x1d/0x28 [kvm] [23154.861677] [<ffffffffa04fa6d4>] kvm_arch_vcpu_ioctl_run+0xcda/0xe45 [kvm] [23154.863604] [<ffffffffa04f5a1a>] ? kvm_arch_vcpu_load+0x17b/0x180 [kvm] Actually, we can use one mmio_fragment to store a large mmio access then split it when we pass the mmio-exit-info to userspace. After that, we only need two entries to store mmio info for the cross-mmio pages access Signed-off-by: Xiao Guangrong <xiaoguangrong@linux.vnet.ibm.com> Signed-off-by: Marcelo Tosatti <mtosatti@redhat.com>

2012-10-30ALSA: Add a reference counter to card instanceTakashi Iwai1-0/+3
For more strict protection for wild disconnections, a refcount is introduced to the card instance, and let it up/down when an object is referred via snd_lookup_*() in the open ops. The free-after-last-close check is also changed to check this refcount instead of the empty list, too.

2012-10-28percpu-rw-semaphores: use rcu_read_lock_schedMikulas Patocka1-4/+4
Use rcu_read_lock_sched / rcu_read_unlock_sched / synchronize_sched instead of rcu_read_lock / rcu_read_unlock / synchronize_rcu. This is an optimization. The RCU-protected region is very small, so there will be no latency problems if we disable preempt in this region. So we use rcu_read_lock_sched / rcu_read_unlock_sched that translates to preempt_disable / preempt_disable. It is smaller (and supposedly faster) than preemptible rcu_read_lock / rcu_read_unlock.

2012-10-28percpu-rw-semaphores: use light/heavy barriersMikulas Patocka1-13/+7
This patch introduces new barrier pair light_mb() and heavy_mb() for percpu rw semaphores. This patch fixes a bug in percpu-rw-semaphores where a barrier was missing in percpu_up_write. This patch improves performance on the read path of percpu-rw-semaphores: on non-x86 cpus, there was a smp_mb() in percpu_up_read. This patch changes it to a compiler barrier and removes the "#if defined(X86) ..." condition.

2012-10-19iio: Add some helper macros for unit conversionLars-Peter Clausen1-0/+16
Some datasheets use a different unit to specify the channel scale than what IIO expects it to be. This patch adds two helper macros which allow to convert units commonly used in datasheets to IIO units: * acceleration: g -> meter / second**2 * angular velocity: degree (/ second) -> rad (/ second) This makes it much more convenient to specify and also easier to verify a channel's scale attribute.

I'm aware that is is a little late for the UAPI renames for the DVB API, but IMHO, it is better to merge it for 3.7, due to two reasons: 1) There is a major rename at 3.7 (not only uapi changes, but also the entire media drivers were reorganized on 3.7, in order to simplify the Kconfig logic, and easy drivers selection, especially for hybrid devices). By confining all those renames there at 3.7 it will cause all the harm at for media developers on just one shot. Stable backports upstream and at distros will likely welcome it as well, as they won't need to check what changed on 3.7 and what was postponed for on 3.8. 2) The V4L2 DocBook Makefile creates a cross-reference between the media API headers and the specs. This helps us _a_lot_ to be sure that all API improvements are properly documented. Every time a header changes from one place to another, DocBook/media/Makefile needs to be patched. Currently, the DocBook breakage patch depends on the DVB UAPI." * 'v4l_for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media: [media] Kconfig: Fix dependencies for driver autoselect options DocBook/media/Makefile: Fix build due to uapi breakage UAPI: (Scripted) Disintegrate include/linux/dvb

2012-10-17UAPI: Remove empty non-UAPI Kbuild filesDavid Howells23-21/+0
Remove non-UAPI Kbuild files that have become empty as a result of UAPI disintegration. They used to have only header-y lines in them and those have now moved to the Kbuild files in the corresponding uapi/ directories. Possibly these should not be removed but rather have a comment inserted to say they are intentionally left blank. This would make it easier to add generated header lines in future without having to restore the infrastructure. Note that at this point not all the UAPI disintegration parts have been merged, so it is likely that more empty Kbuild files will turn up. It is probably necessary to make the files non-empty to prevent the patch program from automatically deleting them when it reduces them to nothing. Signed-off-by: David Howells <dhowells@redhat.com>

2012-10-17UAPI: Make uapi/linux/irqnr.h non-emptyDavid Howells1-0/+4
uapi/linux/irqnr.h was emitted by the UAPI disintegration script as an empty file because the parent linux/irqnr.h had no UAPI stuff in it, despite being marked with "header-y". Unfortunately, the patch program deletes the empty file when applying a kernel patch. It's not clear why this file is part of the UAPI at all. Looking in: /usr/include/linux/irqnr.h there's nothing there but a header reinclusion guard and a comment. So just stick a comment in there as a placeholder. Without this, if the kernel is fabricated from, say, a tarball and a patch, you can get this error when building x86_64 or usermode Linux (and probably others): include/linux/irqnr.h:4:30: fatal error: uapi/linux/irqnr.h: No such file or directory Reported-by: Randy Dunlap <rdunlap@xenotime.net> Reported-by: Alessandro Suardi <alessandro.suardi@gmail.com> Signed-off-by: David Howells <dhowells@redhat.com> cc: Randy Dunlap <rdunlap@xenotime.net> cc: Alessandro Suardi <alessandro.suardi@gmail.com>
