2010-05-25sh: handle early calls to return_address() when using dwarf unwinder.Paul Mundt
The dwarf unwinder ties in to an early initcall, but it's possible that return_address() calls will be made prior to that. This implements some additional error handling in to the dwarf unwinder as well as an exit path in the return_address() case to bail out if the unwinder hasn't come up yet. This fixes a NULL pointer deref in early boot when mempool_alloc() blows up on the not-yet-ready mempool via dwarf_unwind_stack(). Signed-off-by: Paul Mundt <lethal@linux-sh.org>

2010-05-24Revert "ath9k: Group Key fix for VAPs"Linus Torvalds
This reverts commit 03ceedea972a82d343fa5c2528b3952fa9e615d5, since it breaks resume from suspend-to-ram on Rafael's Acer Ferrari One. NetworkManager thinks everything is ok, but it can't connect to the AP to get an IP address after the resume. In fact, it even breaks resume for non-ath9k chipsets: reverting it also fixes Rafael's Toshiba Protege R500 with the iwlagn driver. As Johannes says: "Indeed, this patch needs to be reverted.

2010-05-24timekeeping: Fix timezone updateThomas Gleixner
commit 64ce4c2f (time: Clean up warp_clock()) breaks the timezone update in a very subtle way. To avoid the direct access to timekeeping internals it adds the timezone delta to the current time with timespec_add_safe(). This works nicely when the timezone delta is > 0. If timezone delta is < 0 then the wrap check in timespec_add_safe() triggers and timespec_add_safe() returns TIME_MAX and screws up timekeeping completely. The comment above timespec_add_safe() says: It's assumed that both values are valid (>= 0) Add the timezone seconds adjustment directly. Reported-by: Rafael J.

2010-05-22Blackfin: optimize strncpy a bitRobin Getz
Add a little strncpy optimization which can easily cut boot time by 20%. When the kernel is booting with initramfs, it builds up the filesystem from a cpio archive by calling strncpy_from_user() via fs/namei.c's do_getname() on every file in the archive (which can be lots) with a length of PATH_MAX (1024). This causes the dest of the strncpy to be padded with many NUL bytes. This optimization mostly causes these NUL bytes to be padded with a call to memset() which is already optimized for filling memory quickly, but the hardware loop helps a little bit as well. Boot time measured with 'loglevel=0' so UART speed doesn't get in the way. Signed-off-by: Robin Getz <robin.getz@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2010-05-22Blackfin: move string functions to normal lib/ assemblyRobin Getz
Since 'extern inline' doesn't work correctly in the context of the Linux kernel (too many overriding defines), move the string functions to normal lib/ assembly files (like the existing mem funcs). This avoids the forced inline all over the kernel and allows us to place them constantly in L1. This also avoids some module failures when gcc inserts calls to string functions but the kernel build system doesn't fully consult the library archives.
