| * bsg: Fix build for CONFIG_BLOCK=nPaul Mundt2007-07-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | BLK_DEV_BSG was added outside of the if BLOCK check, which allows it to be enabled when CONFIG_BLOCK=n. This leads to many screenlengths of errors, starting with a parse error on the request_queue_t definition. Obviously this wasn't intended for CONFIG_BLOCK=n usage, so just move the option back in to the block. Caught with a randconfig on sh.

| * | Fix "use after free" / "double free" bug in ati_create_gatt_pages / ↵Jesper Juhl2007-07-26
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ati_free_gatt_pages Hi, Coverity spotted a "use after free" bug in drivers/char/agp/ati-agp.c::ati_create_gatt_pages(). The same one that was in drivers/char/agp/amd-k7-agp.c::amd_create_gatt_pages() The problem is this: If "entry = kzalloc(sizeof(struct ati_page_map), GFP_KERNEL);" fails, then there's a loop in the function to free all entries allocated so far and break out of the allocation loop. That in itself is pretty sane, but then the (now freed) 'tables' is assigned to ati_generic_private.gatt_pages and 'retval' is set to -ENOMEM which causes ati_free_gatt_pages(); to be called at the end of the function. The problem with this is that ati_free_gatt_pages() will then loop 'ati_generic_private.num_tables' times and try to free each entry in tables[] - this is bad since tables has already been freed and furthermore it will call kfree(tables) at the end - a double free. This patch removes the freeing loop in ati_create_gatt_pages() and instead relies entirely on the call to ati_free_gatt_pages() to free everything we allocated in case of an error. It also sets ati_generic_private.num_tables to the actual number of entries allocated instead of just using the value passed in from the caller - this ensures that ati_free_gatt_pages() will only attempt to free stuff that was actually allocated. Note: I'm in no way intimate with this code and I have no way to actually test this patch (besides compile test it), so while I've tried to be careful in reading the code and make sure the patch does the right thing an ACK from someone who actually knows the code in-depth would be very much appreciated.

See [ARM] 4494/1 or commit 7dea1b20066cd30fb54da7e686b16b5e38b46b2d An undefined reference to elf_hwcap prevents linkage, due to changes made by f884b1cf578e079f01682514ae1ae64c74586602 and d1cbbd6b413510c6512f4f80ffd48db1a8dd554a Removing processor.h removes the extern definition of elf_hwcap, which fixes the link issue, but forgets cpu_relax(). So, instead, we'll call barrier() directly.

| * | | | [POWERPC] spufs: Fix incorrect initialization of cbe_spu_info.spusMasato Noguchi2007-07-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We currently initialize cbe_spu_info[].spus in both init_spu_base and spu_sched_init. The initialise in spu_sched_init clears the SPU list, so we end up with no physical SPUs. Because of this, the spu_run syscall will block forever. This change removes the unnecessary initialization in spu_sched_init.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Maple platform has ISA IOs but didn't call the new functions to actually map those, thus crashing when trying to access the nvram. This fixes Maple and JS2x using SLOF. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Paul Mackerras <paulus@samba.org>
