2008-05-13atmel_lcdfb: fix pixclock divider calculationNicolas Ferre
Fix divider calculation and allow CLKVAL = 0 (divisor 2) It was not possible to get the clock value 0 (divisor 2) because the test "<=0" force the BYPASS bit to be activated instead.

2008-05-13rtc: rtc_time_to_tm: use unsigned arithmeticMaciej W. Rozycki
The input argument to rtc_time_to_tm() is unsigned as well as are members of the output structure. However signed arithmetic is used within for calculations leading to incorrect results for input values outside the signed positive range. If this happens the time of day returned is out of range. Found the problem when fiddling with the RTC and the driver where year was set to an unexpectedly large value like 2070, e.g.: rtc0: setting system clock to 2070-01-01 1193046:71582832:26 UTC (3155760954) while it should be: rtc0: setting system clock to 2070-01-01 00:15:54 UTC (3155760954) Changing types to unsigned fixes the problem.

2008-05-13Fix hfsplus oops on image without extentsEric Sesterhenn
Fix an oops with a corrupted hfs+ image. See http://bugzilla.kernel.org/show_bug.cgi?id=10548 for details. Problem is that we call hfs_btree_open() from hfsplus_fill_super() to set HFSPLUS_SB(sb).[ext_tree|cat_tree] Both trees are still NULL at this moment. If hfs_btree_open() fails for any reason it calls iput() on the page, which gets to hfsplus_releasepage() which tries to access HFSPLUS_SB(sb).* which is still NULL and oopses while dereferencing it.

2008-05-13drivers/video/pnx4008: eliminate double freeJulia Lawall
The function framebuffer_release just calls kfree, so calling kfree subsequently on the same argument represents a double free. The comments with the definition of framebuffer_release in drivers/video/fbsysfs.c suggest that a more elaborate definition of this function is planned, such that the splitting up of framebuffer_release and kfree as done in the second instance might someday make sense, but it does not make sense now. This was found using the following semantic match. (http://www.emn.fr/x-info/coccinelle/) // <smpl> @@ expression E; @@ * kfree(E); ... * framebuffer_release(E); @@ expression E; @@ * framebuffer_release(E); ... * kfree(E); // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Cc: Vitaly Wool <vitalywool@gmail.com> Cc: Krzysztof Helt <krzysztof.h1@wp.pl> Cc: Grigory Tolstolytkin <gtolstolytkin@ru.mvista.com> Cc: Antonino Daplas <adaplas@gmail.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2008-05-13md: fix raid5 'repair' operationsDan Williams
commit bd2ab67030e9116f1e4aae1289220255412b37fd "md: close a livelock window in handle_parity_checks5" introduced a bug in handling 'repair' operations. After a repair operation completes we clear the state bits tracking this operation. However, they are cleared too early and this results in the code deciding to re-run the parity check operation. Since we have done the repair in memory the second check does not find a mismatch and thus does not do a writeback. Test results: $ echo repair > /sys/block/md0/md/sync_action $ cat /sys/block/md0/md/mismatch_cnt 51072 $ echo repair > /sys/block/md0/md/sync_action $ cat /sys/block/md0/md/mismatch_cnt 0 (also fix incorrect indentation) Cc: <stable@kernel.org> Tested-by: George Spelvin <linux@horizon.com> Acked-by: NeilBrown <neilb@suse.de> Signed-off-by: Dan Williams <dan.j.williams@intel.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

Sometimes, vfs_quota_off() is called on a partially set up super block (for example when fill_super() fails for some reason). In such cases we cannot call ->sync_fs() because it can Oops because of not properly filled in super block. So in case we find there's not quota to turn off, we just skip everything and return which fixes the above problem.

2008-05-13uml: random driver fixesJeff Dike
The random driver would essentially hang if the host's /dev/random returned -EAGAIN. There was a test of need_resched followed by a schedule inside the loop, but that didn't help and it's the wrong way to work anyway. The right way is to ask for an interrupt when there is input available from the host and handle it then rather than polling. Now, when the host's /dev/random returns -EAGAIN, the driver asks for a wakeup when there's randomness available again and sleeps. The interrupt routine just wakes up whatever processes are sleeping on host_read_wait. There is an atomic_t, host_sleep_count, which counts the number of processes waiting for randomness. When this reaches zero, the interrupt is disabled. An added complication is that async I/O notification was only recently added to /dev/random (by me), so essentially all hosts will lack it. So, we use the sigio workaround here, which is to have a separate thread poll on the descriptor and send an interrupt when there is input on it. This mechanism is activated when a process gets -EAGAIN (activating this multiple times is harmless, if a bit wasteful) and deactivated by the last process still waiting. The module name was changed from "random" to "hw_random" in order for udev to recognize it. The sigio workaround needed some changes. sigio_broken was added for cases when we know that async notification doesn't work. This is now called from maybe_sigio_broken, which deals with pts devices.

2008-05-13uml: fix bad NTP interaction with clockJeff Dike
UML's supposed nanosecond clock interacts badly with NTP when NTP decides that the clock has drifted ahead and needs to be slowed down. Slowing down the clock is done by decrementing the cycle-to-nanosecond multiplier, which is 1. Decrementing that gives you 0 and time is stopped. This is fixed by switching to a microsecond clock, with a multiplier of 1000.

2008-05-13[ALSA] emux midi synthesizer doesn't honor SOFT_PEDAL-release eventmaximilian attems
When the hardware wavetable synthesizer of an Creative SB Audigy or SB Live! card (with emu10k chip) receives the MIDI SOFT_PEADAL-press event (?? 67 127) the appropriate voice is attenuted. Unfortunately when the pedal is released (event ?? 67 0) the voice does not get it's original volume again. Boolean MIDI controls should interpret 0..63 as false and 64..127 as true. Thanks to Clemens Ladisch for review and correction.

2008-05-12Make 'cond_resched()' nullification depend on PREEMPT_BKLLinus Torvalds
Because it's not correct with a non-preemptable BKL and just causes PREEMPT kernels to have longer latencies than non-PREEMPT ones (which is obviously not the point of it at all). Of course, that config option actually got removed as an option earlier, so for now this basically disables it entirely, but if BKL preemption is ever resurrected it will be a meaningful optimization. And in the meantime, it at least documents the intent of the code, while not doing the wrong thing. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2008-05-12Fix up 'need_resched()' definitionLinus Torvalds
We should not go through the task pointer to get at the thread info, since it's usually cheaper to just access the thread info directly. So don't make the code look up 'current', when we can just use the thread info accessor functions directly. This generally avoids one level of indirection and tends to work better together with code that also looks at other thread flags (eg preempt_count).
