Subject: char/agp: consolidate {alloc,free}_gatt_pages()
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=0e4f2c4567953a230b420f2c4460c3368d6509db;p=linux.git

char/agp: consolidate {alloc,free}_gatt_pages()

There is a copy of alloc_gatt_pages() and free_gatt_pages in several
architectures in arch/$ARCH/include/asm/agp.h. All the copies do exactly
the same: alias alloc_gatt_pages() to __get_free_pages(GFP_KERNEL) and
alias free_gatt_pages() to free_pages().

Define alloc_gatt_pages() and free_gatt_pages() in drivers/char/agp/agp.h
and drop per-architecture definitions.
