2012-02-01ssb: fix cardbus slot in hostmodeHauke Mehrtens
ssb supports one extra device on the cardbus. This results in two devices in total, one beeing the host controller itself and the other the external device connected to the hostcontroller over cardbus. This makes the cardbus slot work on the Linksys WRT150N. Reported-by: Aaron Z <aaronz@pls-net.org> Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de> Signed-off-by: John W.

2012-02-01rt2800lib: fix wrong -128dBm when signal is stronger than -12dBmLuigi Tarenga
This patch correct the type of variables containing the rssi values read from the rxwi. In function rt2800_agc_to_rssi() 3 variables (rssi0, rssi1, rss2) defined as int was assigned a 16bit signed values as unsigned. From a test with a hi-gain antenna I verified that the rxwi contains signed rssi values in the range -13/+81 (inclusive) with 0 as an error condition. In case of negative values a condition is triggered and the function return -128dBm while the signal is at its maximum. This patch correct the cast so negative values are not treated as very high positive values (ex. -13 does not become 243).

2012-02-01mtd: fix merge conflict resolution breakageArtem Bityutskiy
This patch fixes merge conflict resolution breakage introduced by merge d3712b9dfcf4 ("Merge tag 'for-linus' of git://github.com/prasad-joshi/logfs_upstream"). The commit changed 'mtd_can_have_bb()' function and made it always return zero, which is incorrect. Instead, we need it to return whether the underlying flash device can have bad eraseblocks or not. UBI needs this information because it affects how it handles the underlying flash. E.g., if the underlying flash is NOR, it cannot have bad blocks and any write or erase error is fatal, and all we can do is to switch to R/O mode. We do not need to reserve a pool of good eraseblocks for bad eraseblocks handling, and so on. This patch also removes 'mtd_can_have_bb()' invocations from Logfs to ensure correct Logfs behavior. I've tested that with this patch UBI works on top of NOR and NAND flashes emulated by mtdram and nandsim correspondingly. This patch is based on patch from Linus Torvalds.

It reports "Not charging" while in fact there is >130mA current flowing to the battery according to current_now. This status report seems to be based on CHG bit in status register, but looking at the datasheet the description says "(Fast) charging allowed", which I guess means that the chip recommends charging and not that charging is actually going on?

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.
