2008-10-02ALSA: snd-powermac: mixers for PowerMac G4 AGPRisto Suominen
Add mixer controls for PowerMac G4 AGP (Screamer).

2008-09-30ALSA: hda - Fix model for Dell Inspiron 1525Takashi Iwai
Dell Inspiron 1525 seems to have a buggy BIOS setup and screws up the recent codec parser, as reported by Oleksandr Natalenko: http://lkml.org/lkml/2008/9/12/203 This patch adds the working model, dell-3stack, statically. Signed-off-by: Takashi Iwai <tiwai@suse.de> Cc: <stable@kernel.org>
2008-09-30ALSA: ASoC: Fix cs4270 error pathJean Delvare
The error path in cs4270_probe/cs4270_remove is pretty broken: * If cs4270_probe fails, codec is leaked. * If snd_soc_register_card fails, cs4270_i2c_driver stays registered. * If I2C support is enabled but no I2C device is found, i2c_del_driver is never called (neither in cs4270_probe nor in cs4270_remove. Fix all 3 problems by implementing a clean error path in cs4270_probe and jumping to its labels as needed.

2008-09-29ALSA: make the CS4270 driver a new-style I2C driverTimur Tabi
Update the CS4270 ALSA device driver to use the new-style I2C interface. Starting with the 2.6.27 PowerPC kernel, I2C devices that have entries in the device trees can no longer be probed by old-style I2C drivers. The device tree for Freescale MPC8610 HPCD has included an entry for the CS4270 since 2.6.25, but that entry was previously ignored by the PowerPC I2C subsystem. Since that's no longer the case, the best solution is to update the CS4270 driver to a new-style interface, rather than try to revert the behavior of new PowerPC I2C subsystem.

2008-09-25ALSA: fix locking in snd_pcm_open*() and snd_rawmidi_open*()Takashi Iwai
The PCM and rawmidi open callbacks have a lock against card->controls_list but it takes a wrong one, card->controls_rwsem, instead of a right one card->ctl_files_rwlock. This patch fixes them. This change also fixes automatically the potential deadlocks due to mm->mmap_sem in munmap and copy_from/to_user, reported by Sitsofe Wheeler: A: snd_ctl_elem_user_tlv(): card->controls_rwsem => mm->mmap_sem B: snd_pcm_open(): card->open_mutex => card->controls_rwsem C: munmap: mm->mmap_sem => snd_pcm_release(): card->open_mutex The patch breaks the chain.

2008-08-29ALSA: oxygen: fix distorted output on AK4396-based cardsClemens Ladisch
When changing the sample rate, the CMI8788's master clock output becomes unstable for a short time. The AK4396 needs the master clock to do SPI writes, so writing to an AK4396 control register directly after a sample rate change will garble the value. In our case, this leads to the DACs being misconfigured to I2S sample format, which results in a wrong output level and horrible distortions on samples louder than -6 dB. To fix this, we need to wait until the new master clock signal has become stable before doing SPI writes.

2008-08-25[x86] Clean up MAXSMP Kconfig, and limit NR_CPUS to 512Linus Torvalds
This fixes a regression that was indirectly caused by commit 1184dc2ffe2c8fb9afb766d870850f2c3165ef25 ("x86: modify Kconfig to allow up to 4096 cpus"). Allowing 4k CPU's is not practical at this time, because we still have a number of places that have several 'cpumask_t's on the stack, and a 4k-bit cpumask is 512 bytes of stack-space for each such variable. This literally caused functions like 'smp_call_function_mask' to have a 2.5kB stack frame, and several functions to have 2kB stackframes. With an 8kB stack total, smashing the stack was simply much too likely. At least bugzilla entry http://bugzilla.kernel.org/show_bug.cgi?id=11342 was due to this. The earlier commit to not inline load_module() into sys_init_module() fixed the particular symptoms of this that Alan Brunelle saw in that bugzilla entry, but the huge stack waste by cpumask_t's was the more direct cause. Some day we'll have allocation helpers that allocate large CPU masks dynamically, but in the meantime we simply cannot allow cpumasks this large. Cc: Alan D.

2008-08-25[module] Don't let gcc inline load_module()Linus Torvalds
'load_module()' is a complex function that contains all the ELF section logic, and inlining it is utterly insane. But gcc will do it, simply because there is only one call-site. As a result, all the stack space that is allocated for all the work to load the module will still be active when we actually call the module init sequence, and the deep call chain makes stack overflows happen. And stack overflows are really hard to debug, because they not only corrupt random pages below the stack, but also corrupt the thread_info structure that is allocated under the stack. In this case, Alan Brunelle reported some crazy oopses at bootup, after loading the processor module that ends up doing complex ACPI stuff and has quite a deep callchain. This should fix it, and is the sane thing to do regardless. Cc: Alan D.

2008-08-25sched_clock: fix cpu_clock()Peter Zijlstra
This patch fixes 3 issues: a) it removes the dependency on jiffies, because jiffies are incremented by a single CPU, and the tick is not synchronized between CPUs. Therefore relying on it to calculate a window to clip whacky TSC values doesn't work as it can drift around. So instead use [GTOD, GTOD+TICK_NSEC) as the window. b) __update_sched_clock() did (roughly speaking): delta = sched_clock() - scd->tick_raw; clock += delta; Which gives exponential growth, instead of linear. c) allows the sched_clock_cpu() value to warp the u64 without breaking. the results are more reliable sched_clock() deltas: before after sched_clock cpu_clock: 15750 51312 51488 cpu_clock: 59719 51052 50947 cpu_clock: 15879 51249 51061 cpu_clock: 1 50933 51198 cpu_clock: 1 50931 51039 cpu_clock: 1 51093 50981 cpu_clock: 1 51043 51040 cpu_clock: 1 50959 50938 cpu_clock: 1 50981 51011 cpu_clock: 1 51364 51212 cpu_clock: 1 51219 51273 cpu_clock: 1 51389 51048 cpu_clock: 1 51285 51611 cpu_clock: 1 50964 51137 cpu_clock: 1 50973 50968 cpu_clock: 1 50967 50972 cpu_clock: 1 58910 58485 cpu_clock: 1 51082 51025 cpu_clock: 1 50957 50958 cpu_clock: 1 50958 50957 cpu_clock: 1006128 51128 50971 cpu_clock: 1 51107 51155 cpu_clock: 1 51371 51081 cpu_clock: 1 51104 51365 cpu_clock: 1 51363 51309 cpu_clock: 1 51107 51160 cpu_clock: 1 51139 51100 cpu_clock: 1 51216 51136 cpu_clock: 1 51207 51215 cpu_clock: 1 51087 51263 cpu_clock: 1 51249 51177 cpu_clock: 1 51519 51412 cpu_clock: 1 51416 51255 cpu_clock: 1 51591 51594 cpu_clock: 1 50966 51374 cpu_clock: 1 50966 50966 cpu_clock: 1 51291 50948 cpu_clock: 1 50973 50867 cpu_clock: 1 50970 50970 cpu_clock: 998306 50970 50971 cpu_clock: 1 50971 50970 cpu_clock: 1 50970 50970 cpu_clock: 1 50971 50971 cpu_clock: 1 50970 50970 cpu_clock: 1 51351 50970 cpu_clock: 1 50970 51352 cpu_clock: 1 50971 50970 cpu_clock: 1 50970 50970 cpu_clock: 1 51321 50971 cpu_clock: 1 50974 51324 Signed-off-by: Peter Zijlstra <a.p.zijlstra@chello.nl> Signed-off-by: Ingo Molnar <mingo@elte.hu>

2008-08-25KVM: Use .fixup instead of .text.fixup on __kvm_handle_fault_on_rebootEduardo Habkost
vmlinux.lds expects the fixup code to be on a section named .fixup. The .text.fixup section is not mentioned on vmlinux.lds, and is included on the resulting vmlinux (just after .text) only because of ld heuristics on placing orphan sections. However, placing .text.fixup outside .text breaks the definition of _etext, making it exclude the .text.fixup contents. That makes .text.fixup be ignored by the kernel initialization code that needs to know about section locations, such as the code setting page protection bits.

Both v and vb->num_pages are u32 and unsigned int respectively. If v is less than vb->num_pages (and it is, when deflating the balloon), the result is a very large 32-bit number. Since we're returning a s64, instead of getting the same negative number we desire, we get a very large positive number. This handles the case where v < vb->num_pages and ensures we get a small, negative, s64 as the result. Rusty: please push this for 2.6.27-rc4. It's probably appropriate for the stable tree too as it will cause an unexpected OOM when ballooning.
