Subject: linux-next: build failure after merge of the final tree (block tree
 related)

Hi all,

After merging the final tree, today's linux-next build (powerpc
allyesconfig) failed like this:

drivers/char/tpm/tpm_tis.c:96: warning: 'is_itpm' defined but not used
drivers/block/drbd/drbd_bitmap.c: In function '__bm_change_bits_to':
drivers/block/drbd/drbd_bitmap.c:1287: error: implicit declaration of function 'generic___test_and_set_le_bit'
drivers/block/drbd/drbd_bitmap.c:1289: error: implicit declaration of function 'generic___test_and_clear_le_bit'
drivers/block/drbd/drbd_bitmap.c: In function 'drbd_bm_test_bit':
drivers/block/drbd/drbd_bitmap.c:1438: error: implicit declaration of function 'generic_test_le_bit'

Caused by commit 4b0715f09655 ("drbd: allow petabyte storage on 64bit
arch").

I have applied this patch for today (surely there is a better way):
