* random: don't try to look at entropy_count outside the lockMatt Mackall2009-01-06
| | | | | | | | | | | | | | | | | | As a non-atomic value, it's only safe to look at entropy_count when the pool lock is held, so we move the BUG_ON inside the lock for correctness. Also remove the spurious comment. It's ok for entropy_count to temporarily exceed POOLBITS so long as it's left in a consistent state when the lock is released. This is a more correct, simple, and idiomatic fix for the bug in 8b76f46a2db. I've left the reorderings introduced by that patch in place as they're harmless, even though they don't properly deal with potential atomicity issues.

* make firmware/dsp56k/bootstrap.asm buildable on a56Robert Millan2009-01-06
| | | | | | | | | | | | | | | | | | | | Make firmware/dsp56k/bootstrap.asm buildable on a56, the free Motorola DSP56001 assembler (http://www.zdomain.com/a56.html). Summary of changes: - Remove '<' and '>' candy (they specify explicit addressing modes, which a56 don't grok, but uses implicitly anyway). - Replace 'move' with 'movem' when accessing program memory. - Rename a few labels to avoid duplicates (which a56 can't handle).

* coredump_filter: permit changing of the default filterHidehiro Kawai2009-01-06
| | | | | | | | | | | | | | | | Introduce a new kernel parameter `coredump_filter'. Setting a value to this parameter causes the default bitmask of coredump_filter to be changed. It is useful for users to change coredump_filter settings for the whole system at boot time. Without this parameter, users have to change coredump_filter settings for each /proc/<pid>/ in an initializing script.

* SEND_SIG_NOINFO: set si_pid to tgid instead of pidSukadev Bhattiprolu2009-01-06
| | | | | | | | | | | | | | | | | | | | | | POSIX requires the si_pid to be the process id of the sender, so ->si_pid should really be set to 'tgid'. This change does have following changes in behavior: - When sending pdeath_signal on re-parent to a sub-thread, ->si_pid cannot be used to identify the thread that did the re-parent since it will now show the tgid instead of thread id. - A multi-threaded application that expects to find the specific thread that encountered a SIGPIPE using the ->si_pid will now break.

* fbdev/logo: check compatibility of main and extra logosGeert Uytterhoeven2009-01-06
| | | | | | | | | | | | | | | | | | | | | | The code to draw penguin logos always uses some properties of the main logo. This is incorrect if additional logos (CONFIG_FB_LOGO_EXTRA=y) have different types than the main logo, which causes corrupted logo images. http://bugzilla.kernel.org/show_bug.cgi?id=12181 Hence skip additional logos that are not compatible with the main logo. Technically, it's possible to draw multiple logos of different types on truecolor displays, but this would complicate the (already quite complicated) logo drawing code even more.

| | | | | | | | | | | | | | | | | Small fixes for the pxa27x/pxa3xx driver - use platform_driver_probe - fixed exit paths - fixed probe sequence - added missing include - using linux/io.h instead of asm/io.h Signed-off-by: Alessandro Zummo <a.zummo@towertech.it> Tested-by: Robert Jarzmik <robert.jarzmik@free.fr> Cc: Jonathan Cameron <jic23@cam.ac.uk> Cc: David Brownell <david-b@pacbell.net> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
* rtc: driver for pxa27x and pxa3xx SoCRobert Jarzmik2009-01-06
| | | | | | | | | | | | | | | | | | | With PXA27x and above, a new RTC hardware block was added in addition to the legacy one which is also found on the SA1100 SOC family. This second RTC block is called "wristwatch" and "periodic interrupt" and works independently from the other RTC block. The driver offers provides : - a 1Hz ticking clock - a periodic alarm, in the 1Hz to 1000Hz range - a one shot alarm Signed-off-by: Robert Jarzmik <robert.jarzmik@free.fr> Cc: Jonathan Cameron <jic23@cam.ac.uk> Signed-off-by: Alessandro Zummo <a.zummo@towertech.it> Cc: David Brownell <david-b@pacbell.net> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
* rtc: move power of 2 periodic frequency check down into driversJonathan Cameron2009-01-06
| | | | | | | | | | | | | Move the power of 2 check on frequencies down into individual rtc drivers This is to allow for non power of 2 real time clock periodic interrupts such as those on the pxa27x to be found in the new pxa27x-rtc driver Signed-off-by: Jonathan Cameron <jic23@cam.ac.uk> Signed-off-by: Alessandro Zummo <a.zummo@towertech.it> Cc: David Brownell <david-b@pacbell.net> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
* rtc: bunch of drivers: fix 'no irq' case handingAnton Vorontsov2009-01-06
| | | | | | | | | | | | | | | | | | This patch fixes a bunch of irq checking misuses. Most drivers were getting irq via platform_get_irq(), which returns -ENXIO or r->start. rtc-cmos.c is special. It is using PNP and platform bindings. Hopefully nobody is using PNP IRQ 0 for RTC. So the changes should be safe. rtc-sh.c is using platform_get_irq, but was storing a result into an unsigned type, then was checking for < 0. This is fixed now.
