2012-02-01drm/radeon: Set DESKTOP_HEIGHT register to the framebuffer (not mode) height.Michel Dänzer
The value of this register is transferred to the V_COUNTER register at the beginning of vertical blank. V_COUNTER is the reference for VLINE waits and goes from VIEWPORT_Y_START to VIEWPORT_Y_START+VIEWPORT_HEIGHT during scanout, so if VIEWPORT_Y_START is not 0, V_COUNTER actually went backwards at the beginning of vertical blank, and VLINE waits excluding the whole scanout area could never finish (possibly only if VIEWPORT_Y_START is larger than the length of vertical blank in scanlines). Setting DESKTOP_HEIGHT to the framebuffer height should prevent this for any kind of VLINE wait. Fixes https://bugs.freedesktop.org/show_bug.cgi?id=45329 .

2012-02-01KVM: x86: fix missing checks in syscall emulationStephan Bärwolf
On hosts without this patch, 32bit guests will crash (and 64bit guests may behave in a wrong way) for example by simply executing following nasm-demo-application: [bits 32] global _start SECTION .text _start: syscall (I tested it with winxp and linux - both always crashed) Disassembly of section .text: 00000000 <_start>: 0: 0f 05 syscall The reason seems a missing "invalid opcode"-trap (int6) for the syscall opcode "0f05", which is not available on Intel CPUs within non-longmodes, as also on some AMD CPUs within legacy-mode. (depending on CPU vendor, MSR_EFER and cpuid) Because previous mentioned OSs may not engage corresponding syscall target-registers (STAR, LSTAR, CSTAR), they remain NULL and (non trapping) syscalls are leading to multiple faults and finally crashs. Depending on the architecture (AMD or Intel) pretended by guests, various checks according to vendor's documentation are implemented to overcome the current issue and behave like the CPUs physical counterparts.

2012-02-01KVM: Fix __set_bit() race in mark_page_dirty() during dirty loggingTakuya Yoshikawa
It is possible that the __set_bit() in mark_page_dirty() is called simultaneously on the same region of memory, which may result in only one bit being set, because some callers do not take mmu_lock before mark_page_dirty(). This problem is hard to produce because when we reach mark_page_dirty() beginning from, e.g., tdp_page_fault(), mmu_lock is being held during __direct_map(): making kvm-unit-tests' dirty log api test write to two pages concurrently was not useful for this reason. So we have confirmed that there can actually be race condition by checking if some callers really reach there without holding mmu_lock using spin_is_locked(): probably they were from kvm_write_guest_page(). To fix this race, this patch changes the bit operation to the atomic version: note that nr_dirty_pages also suffers from the race but we do not need exactly correct numbers for now.

If cs_automic is called twice (like it is during init) while the mic is present, it will over-write the last_input with the new one, causing it to switch back to the automic input when the mic is unplugged. This leaves the driver in a state (cur_input, last_input, and automix_idx the same) where the internal mic can not be selected until it is rebooted without the mic attached.

2012-01-31ASoC: core: Better support for idle_bias_off suspend ignoresMark Brown
If an idle_bias_off device is in any state other than off then it is still active for some reason (typically a low power function such as accessory detection). This wasn't an issue when the feature was implemented as we always went to _ON for any active function, subsequent power improvements have changed things. With the modern way of doing things we should overhaul the infrastructure to allow devices to explicitly take references for these functions but that's a much more invasive change and will require driver updates to deploy, this will bring the framework into line with the existing driver set before we do that work.

This resolution takes the semantics from commit f2933e86ad93, and just makes mtd_block_isbad() return zero (false) if the 'block_isbad' function is NULL. But that also means that now "mtd_can_have_bb()" always returns 0. Now, "mtd_block_markbad()" will obviously return an error if the low-level driver doesn't support bad blocks, so this is somewhat non-symmetric, but it actually makes sense if a NULL "block_isbad" function is considered to mean "I assume that all my blocks are always good".

2012-01-30perf top: Fix number of samples displayedStephane Eranian
In recent versions of perf top, pressing the 'e' key to change the number of displayed samples had no effect. The number of samples was still dictated by the size of the terminal (stdio mode). That was quite annoying because typically only the first dozen samples really matter. This patch fixes this.

2012-01-30perf tools: Fix strlen() bug in perf_event__synthesize_event_type()Stephane Eranian
The event_type record has a max length for the event name. It's called MAX_EVENT_NAME. The name may be truncated to fit the max length. But the header.size still reflects the original name length. If that length is > MAX_EVENT_NAME, then the header.size field is bogus. Fix this by using the length of the name after the potential truncation.
