2012-09-13USB: atm: usbatm: fix up debug printing codeGreg Kroah-Hartman
If VERBOSE_DEBUG was enabled, lots of build errors happend (obviously no one uses this mode.) So fix that up, and get rid of the dbg() call, and use dev_dbg() like the rest of the driver does. Cc: Duncan Sands <duncan.sands@free.fr> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

2012-09-13USB: serial: add zte_ev.c driverGreg Kroah-Hartman
This adds a driver for the zte_ev set of usb to serial devices. It is based on a patch floating around the internet that modified the generic usb-serial driver to only work for this type of device. I've left comments in the code that I think show the data commands being sent to the device, which I'm guessing come from a usb analyzer. Maybe they can help others out as well. Many thanks to nirinA raseliarison for pointing the original patch out to me, and for testing that the driver works properly.

2012-09-13locking: Adjust spin lock inlining Kconfig optionsJan Beulich
Break out the DEBUG_SPINLOCK dependency (requires moving up UNINLINE_SPIN_UNLOCK, as this was the only one in that block not depending on that option). Avoid putting values not selected into the resulting .config - they are not useful for anything, make the output less legible, and just consume space: Use "depends on" rather than directly setting the default from the combined dependency values.

2012-09-13x86/Kconfig: Clean up Kconfig defaultsJan Beulich
The main goal here is to have the resulting .config no carry any options that aren't enabled and can't be (i.e such where the default is "no" and can't be changed), so that if any such option later gets a user visible prompt, the user will actually be prompted on a "make ...oldconfig" rather than keeping the previously invisible option disabled. There's a little bit of other trivial cleanup mixed in here.

2012-09-13x86: Prefer TZCNT over BFSJan Beulich
Following a relatively recent compiler change, make use of the fact that for non-zero input BSF and TZCNT produce the same result, and that CPUs not knowing of TZCNT will treat the instruction as BSF (i.e. ignore what looks like a REP prefix to them). The assumption here is that TZCNT would never have worse performance than BSF. For the moment, only do this when the respective generic-CPU option is selected (as there are no specific-CPU options covering the CPUs supporting TZCNT), and don't do that when size optimization was requested.

2012-09-13x86/64: Adjust types of temporaries used by ffs()/fls()/fls64()Jan Beulich
The 64-bit special cases of the former two (the thrird one is 64-bit only anyway) don't need to use "long" temporaries, as the result will always fit in a 32-bit variable, and the functions return plain "int". This avoids a few REX prefixes, i.e. minimally reduces code size.

2012-09-13time: Fix timeekeping_get_ns overflow on 32bit systemsJohn Stultz
Daniel Lezcano reported seeing multi-second stalls from keyboard input on his T61 laptop when NOHZ and CPU_IDLE were enabled on a 32bit kernel. He bisected the problem down to commit 1e75fa8be9fb6 ("time: Condense timekeeper.xtime into xtime_sec"). After reproducing this issue, I narrowed the problem down to the fact that timekeeping_get_ns() returns a 64bit nsec value that hasn't been accumulated. In some cases this value was being then stored in timespec.tv_nsec (which is a long). On 32bit systems, with idle times larger then 4 seconds (or less, depending on the value of xtime_nsec), the returned nsec value would overflow 32bits. This limited kept time from increasing, causing timers to not expire. The fix is to make sure we don't directly store the result of timekeeping_get_ns() into a tv_nsec field, instead using a 64bit nsec value which can then be added into the timespec via timespec_add_ns().

2012-09-13x86: Drop unnecessary kernel_eflags variable on 64-bitIan Campbell
On 64 bit x86 we save the current eflags in cpu_init for use in ret_from_fork. Strictly speaking reserved bits in EFLAGS should be read as written but in practise it is unlikely that EFLAGS could ever be extended in this way and the kernel alread clears any undefined flags early on. The equivalent 32 bit code simply hard codes 0x0202 as the new EFLAGS. This change makes 64 bit use the same mechanism to setup the initial EFLAGS on fork. Note that 64 bit resets EFLAGS before calling schedule_tail() as opposed to 32 bit which calls schedule_tail() first. Therefore the correct value for EFLAGS has opposite IF bit.

Commit f319da0c68 ("sched: Fix load avg vs cpu-hotplug") was an incomplete fix: In particular, the problem is that at the point it calls calc_load_migrate() nr_running := 1 (the stopper thread), so move the call to CPU_DEAD where we're sure that nr_running := 0. Also note that we can call calc_load_migrate() without serialization, we know the state of rq is stable since its cpu is dead, and we modify the global state using appropriate atomic ops.

2012-09-13GFS2: Take account of blockages when using reserved blocksSteven Whitehouse
The claim_reserved_blks() function was not taking account of the possibility of "blockages" while performing allocation. This can be caused by another node allocating something in the same extent which has been reserved locally. This patch tests for this condition and then skips the remainder of the reservation in this case. This is a relatively rare event, so that it should not affect the general performance improvement which the block reservations provide. The claim_reserved_blks() function also appears not to be able to deal with reservations which cross bitmap boundaries, but that can be dealt with in a future patch since we don't generate boundary crossing reservations currently.

The JMicron JMB362 controller supports AHCI only, but some revisions use the IDE class code. These need to be matched by device ID. These additions have apparently been included by QNAP in their NAS devices using these controllers.

2012-09-13drm: Drop the NV12M and YUV420M formatsVille Syrjälä
The NV12M/YUV420M formats are identical to the NV12/YUV420 formats. So just remove these duplicated format names. This might look like breaking the ABI, but the code has never actually accepted these formats, so nothing can be using them.

2012-09-13drm/exynos: remove DRM_FORMAT_NV12M from plane moduleInki Dae
this patch removes DRM_FORMAT_NV12M from plane module because this format is same as DRM_FORMAT_NV12. DRM_FORMAT_NV12M will be identified by mode_cmd->handles and mode_cmd->offsets fields internally.
