The patch titled add upper-32-bits macro has been removed from the -mm tree. Its filename was upper-32-bits.patch This patch was dropped because it was merged into mainline or a subsystem tree ------------------------------------------------------ Subject: add upper-32-bits macro From: Andrew Morton <akpm@xxxxxxxxxxxxxxxxxxxx> We keep on getting "right shift count >= width of type" warnings when doing things like sector_t s; x = s >> 56; because with CONFIG_LBD=n, s is only 32-bit. Similar problems can occur with dma_addr_t's. So add a simple wrapper function which code can use to avoid this warning. The above example would become x = upper_32_bits(s) >> 24; The first user is in fact AFS.
