2012-05-22CG2900: changing sleep timersNitin Dhingra
Reducing the sleep timer value from 10 sec to 150ms, to put CG29XX chip to sleep. and after 50ms checking CG29XX has gone to sleep then release the wakelocks for system to go in sleep mode. This will decrease the power consumption greatly.

2012-05-22CG2900: Fix timings for CG29XX during breakNitin Dhingra
In Reference to CG29x0 low power mode control document, there are some fixes required in CG2900 protocol driver for break conditions. 1)Pre-break - 900usec - This is the minimal time before Host sending a break after it completes sending data on Tx_Host line. 2)in-break - 5msec - This is the minimal time that Host should maintain the break. 3)post-break - 200usec - This is the minimal time before Host starting sending data on Tx_Host line after it exits break.

2012-05-22cg2900: Code optimizations for CG2900 init timenitin.dhingra
Some general code optimizations during intialization done. Also we are releasing clock user like WLAN earlier as READ SELF TEST is not required for WLAN functionality. All these optimizations are done to reduce CG2900 init time which will also impact WLAN start-up time. Also ESD Clamp workaround has been removed from the code completely. This is not required anymore.

2012-05-22cg2900: [U9500] Correct the GPIO configuration for WLANPhilippe Langlais
There are two parts in this correction. Firstly, as there is much in common between a U9500 platform and a U8500 one, all the tests performed to identify a U9500 platform shall be done before the ones related to U8500. Otherwise, the platform will be considered as a U8500 one and the GPIOs will be badly configured. Secondly, the mapping of WLAN_IRQ has to be changed. On U8500, WLAN_IRQ is mapped onto GPIO04. On U9500, it is GPIO144 that shall be used. ST-Ericsson ID: 368270 ST-Ericsson Linux next: NA ST-Ericsson FOSS-OUT ID: Trivial Signed-off-by: Rejane DURAND <rejane.durand@stericsson.com>

git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull x86 linker bug workarounds from Peter Anvin. GNU ld-2.22.52.0.[12] (*) has an unfortunate bug where it incorrectly turns certain relocation entries absolute. Section-relative symbols that are part of otherwise empty sections are silently changed them to absolute. We rely on section-relative symbols staying section-relative, and actually have several sections in the linker script solely for this purpose. See for example http://sourceware.org/bugzilla/show_bug.cgi?id=14052 We could just black-list the buggy linker, but it appears that it got shipped in at least F17, and possibly other distros too, so it's sadly not some rare unusual case. This backports the workaround from the x86/trampoline branch, and as Peter says: "This is not a minimal fix, not at all, but it is a tested code base." * 'x86/ld-fix' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86, relocs: When printing an error, say relative or absolute x86, relocs: Workaround for binutils 2.22.52.0.1 section bug x86, realmode: 16-bit real-mode code support for relocs tool (*) That's a manly release numbering system.

2012-05-19memcg,thp: fix res_counter:96 regressionHugh Dickins
Occasionally, testing memcg's move_charge_at_immigrate on rc7 shows a flurry of hundreds of warnings at kernel/res_counter.c:96, where res_counter_uncharge_locked() does WARN_ON(counter->usage < val). The first trace of each flurry implicates __mem_cgroup_cancel_charge() of mc.precharge, and an audit of mc.precharge handling points to mem_cgroup_move_charge_pte_range()'s THP handling in commit 12724850e806 ("memcg: avoid THP split in task migration"). Checking !mc.precharge is good everywhere else, when a single page is to be charged; but here the "mc.precharge -= HPAGE_PMD_NR" likely to follow, is liable to result in underflow (a lot can change since the precharge was estimated). Simply check against HPAGE_PMD_NR: there's probably a better alternative, trying precharge for more, splitting if unsuccessful; but this one-liner is safer for now - no kernel/res_counter.c:96 warnings seen in 26 hours.
