2009-03-30MIPS: Alchemy: unify CPU model constants.Manuel Lauss
This patch removes the various CPU_AU1??? model constants in favor of a single CPU_ALCHEMY one. All currently existing Alchemy models are identical in terms of cpu core and cache size/organization. The parts of the mips kernel which need to know the exact CPU revision extract it from the c0_prid register already; and finally nothing else in-tree depends on those any more. Should a new variant with slightly different "company options" and/or "processor revision" bits in c0_prid appear, it will be supported immediately (minus an exact model string in cpuinfo).

The following changes are made along with replacing set_irq_chip() with set_irq_chip_and_handler_name(,,handle_edge_irq,"edge"): * Fix emma2rh_gpio_irq_ack not to disable interrupts With handle_edge_irq(), we're not expected to disable interrupts when chip->ack is served, so fix it accordingly. We also add a new emma2rh_gpio_irq_mask_ack() for chip->mask_ack operation, instead. * Remove emma2rh_gpio_irq_end(), as chip->end is no longer served.

2009-03-30MIPS: __raw_spin_lock() may spin forever on ticket wrap.David Daney
If the lock is not acquired and has to spin *and* the second attempt to acquire the lock fails, the delay time is not masked by the ticket range mask. If the ticket number wraps around to zero, the result is that the lock sampling delay is essentially infinite (due to casting -1 to an unsigned int). The fix: Always mask the difference between my_ticket and the current ticket value before calculating the delay.

2009-03-27generic compat_sys_ustatChristoph Hellwig
Due to a different size of ino_t ustat needs a compat handler, but currently only x86 and mips provide one. Add a generic compat_sys_ustat and switch all architectures over to it. Instead of doing various user copy hacks compat_sys_ustat just reimplements sys_ustat as it's trivial. This was suggested by Arnd Bergmann. Found by Eric Sandeen when running xfstests/017 on ppc64, which causes stack smashing warnings on RHEL/Fedora due to the too large amount of data writen by the syscall.

device_driver' This patch fixes the bug reported in http://bugzilla.kernel.org/show_bug.cgi?id=11681. "Lots of device drivers register a 'struct device_driver' with the '.bus' member set to '&platform_bus_type'. This is wrong, since the platform_bus functions expect the 'struct device_driver' to be wrapped up in a 'struct platform_driver' which provides some additional callbacks (like suspend_late, resume_early). The effect may be that platform_suspend_late() uses bogus data outside the device_driver struct as a pointer pointer to the device driver's suspend_late() function or other hard to reproduce failures."(Lothar Wassmann) Signed-off-by: Ming Lei <tom.leiming@gmail.com> Acked-by: Henrique de Moraes Holschuh <hmh@hmh.eng.br> Acked-by: David Brownell <dbrownell@users.sourceforge.net> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
