* [PATCH] Correct misc_register return code handling in several driversNeil Horman2006-12-073-5/+21
| | | | | | | | | | | | | | | | | | | | | | | | | Clean up several code points in which the return code from misc_register is not handled properly. Several modules failed to deregister various hooks when misc_register fails, and this patch cleans them up. Also there are a few modules that legitimately don't care about the failure status of misc register. These drivers however unilaterally call misc_deregister on module unload. Since misc_register doesn't initialize the list_head in the init_routine if it fails, the deregister operation is at risk for oopsing when list_del is called. The initial solution was to manually init the list in the miscdev structure in each of those modules, but the consensus in this thread was to consolodate and do that universally inside misc_register.

| * | [AGP] Allocate AGP pages with GFP_DMA32 by defaultLinus Torvalds2006-11-222-2/+2

AGP sub-drivers that really care, and can do better, could just choose to implement their own allocator (or we could add another "64-bit safe" default allocator for their use), but quite frankly, you're not likely to care in practice. So for now, this trivial change means that we won't be allocating pages that we can't map correctly by mistake on x86-64. [ On traditional 32-bit x86, this could never happen, because GFP_KERNEL would never allocate any highmem memory anyway ] Acked-by: Andi Kleen <ak@suse.de> Acked-by: Dave Jones <davej@redhat.com> Cc: Eric Anholt <eric@anholt.net> Cc: Keith Packard <keithp@keithp.com> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
| * | [AGP] Fix intel 965 AGP memory mapping functionLinus Torvalds2006-11-221-7/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This introduces a i965-specific "mask_memory()" function that knows about the extended physical addresses that the i965 supports. This allows us to correctly map in physical memory in the >4GB range into the GTT. Also simplify/clean-up the i965 case for the aperture sizing by just returning the fixed 512kB size from "fetch_size()". We don't really care that not all of the aperture may be visible - the only thing that cares about the aperture size is the Intel "stolen memory" calculation, which depends on the fixed size.
