2008-09-26[ARM] pxa: better MFP low power state support for pxa25x/pxa27xEric Miao
When configured as a specific low power state: MFP_LPM_DRIVE_LOW, MFP_LPM_DRIVE_HIGH, the corresponding GPDR register bit during low power mode shall be re-configured as output (if they are not configured so), thus the PGSRx bits can output.

2008-09-09lib: Correct printk %pF to work on all architecturesJames Bottomley
It was introduced by "vsprintf: add support for '%pS' and '%pF' pointer formats" in commit 0fe1ef24f7bd0020f29ffe287dfdb9ead33ca0b2. However, the current way its coded doesn't work on parisc64. For two reasons: 1) parisc isn't in the #ifdef and 2) parisc has a different format for function descriptors Make dereference_function_descriptor() more accommodating by allowing architecture overrides. I put the three overrides (for parisc64, ppc64 and ia64) in arch/kernel/module.c because that's where the kernel internal linker which knows how to deal with function descriptors sits.

2008-09-09[S390] CVE-2008-1514: prevent ptrace padding area read/write in 31-bit modeJarod Wilson
When running a 31-bit ptrace, on either an s390 or s390x kernel, reads and writes into a padding area in struct user_regs_struct32 will result in a kernel panic. This is also known as CVE-2008-1514. Test case available here: http://sources.redhat.com/cgi-bin/cvsweb.cgi/~checkout~/tests/ptrace-tests/tests/user-area-padding.c?cvsroot=systemtap Steps to reproduce: 1) wget the above 2) gcc -o user-area-padding-31bit user-area-padding.c -Wall -ggdb2 -D_GNU_SOURCE -m31 3) ./user-area-padding-31bit <panic> Test status ----------- Without patch, both s390 and s390x kernels panic. With patch, the test case, as well as the gdb testsuite, pass without incident, padding area reads returning zero, writes ignored. Nb: original version returned -EINVAL on write attempts, which broke the gdb test and made the test case slightly unhappy, Jan Kratochvil suggested the change to return 0 on write attempts.

2008-09-08x86: disable static NOPLs on 32 bitsLinus Torvalds
On 32-bit, at least the generic nops are fairly reasonable, but the default nops for 64-bit really look pretty sad, and the P6 nops really do look better. So I would suggest perhaps moving the static P6 nop selection into the CONFIG_X86_64 thing. The alternative is to just get rid of that static nop selection, and just have two cases: 32-bit and 64-bit, and just pick obviously safe cases for them. Signed-off-by: H. Peter Anvin <hpa@zytor.com>

2008-09-08powerpc/spufs: Fix possible scheduling of a context to multiple SPEsAndre Detsch
We currently have a race when scheduling a context to a SPE - after we have found a runnable context in spusched_tick, the same context may have been scheduled by spu_activate(). This may result in a panic if we try to unschedule a context that has been freed in the meantime. This change exits spu_schedule() if the context has already been scheduled, so we don't end up scheduling it twice.
