| * Resurrect IT8172 IDE controller driverShane McDonald2009-01-063-0/+174
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Support for the IT8172 IDE controller was removed from the kernel sometime after 2.6.18. Support for the only boards that used the IT8172 was removed from the kernel after 2.6.18, as they had never compiled since 2.6.0. However, there are a couple of platforms that use this chip: the PMC-Sierra Xiao Hu thin-client computer, which is no longer in production, and the Linksys NSS4000 Network Attached Storage box, which is based on the Xiao Hu board. I am attempting to add support for the Xiao Hu to the kernel, and this IT8172 IDE controller is the first bit of code in this effort. This patch resurrects the IT8172 IDE controller code. I began with the 2.6.18 version of the it8172.c file, and have moved it forward so that it works with the latest version of the kernel. I have run this driver on a PMC-Sierra Xiao Hu board with the 2.6.28 kernel, and I have had no problems with it in my configuration. The attached patch applies cleanly against 2.6.28.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit 295f00042aaf6b553b5f37348f89bab463d4a469 ("ide: don't execute the next queued command from the hard-IRQ context") overlooked that ide_do_drive_cmd() (used for REQUEST SENSE command handling) may still invoke do_ide_request() (->request_fn) in the hard-IRQ context through blk_start_queueing(). This resulted in a LOCKDEP warning after commit b599bc7a1199419e122cb2e9ec6b0fa2cfbbc17b ("ide: use per-device request queue locks (v2)"). Since calling blk_start_queuing() in ide_do_drive_cmd() doesn't make much sense as the port is already marked as busy (so the execution of the new command will be deferred anyway) then just remove it fixing LOCKDEP warning and saving some CPU cycles at the same time.

* | parport: ieee1284: use del_timer_sync() in parport_wait_event()Michael Buesch2009-01-071-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Use del_timer_sync() instead of del_timer() to make sure the timer won't be running when we return from parport_wait_event(), because this would crash due to destruction of timer_list. This is untested and just based on a code review. Just think about the following sequence of events: - add_timer() - down_interruptible() is interrupted by a signal. - we enter the timer callback handler on another CPU. - del_timer(), but the timer callback is still running. - eturn from parport_wait_even, which destroys the automatic variable "timer" while the callback is running on another CPU.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* | fbdev/logo: check compatibility of main and extra logosGeert Uytterhoeven2009-01-071-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. This patch fixes a problem with Debian's linux-image-2.6.26-1-powerpc64 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=508173 Signed-off-by: Geert Uytterhoeven <Geert.Uytterhoeven@sonycom.com> Cc: Krzysztof Helt <krzysztof.h1@poczta.fm> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
