Based on top of "lib/bitmap: add bitmap_{read,write}()"[0] from Alexander
Potapenko as it uses those new bitmap_{read,write}() functions to not
introduce another pair of similar ones.
Derived from the PFCP support series[1] as this grew bigger (2 -> 13
commits in v2) and involved more core bitmap changes, finally transforming
into a pure bitmap series. The actual mentioned ip_tunnel flags conversion
from `__be16` to bitmaps will be submitted bundled with the PFCP set after
this one lands.
Little breakdown:
* #1, #8, #10: misc cleanups;
* #2, #5, #6, #7: symbol scope, name collisions;
* #3, #4, #9, #11: compile-time optimizations.

Alexander Lobakin (11):
bitops: add missing prototype check
bitops: make BYTES_TO_BITS() treewide-available
bitops: let the compiler optimize {__,}assign_bit()
linkmode: convert linkmode_{test,set,clear,mod}_bit() to macros
s390/cio: rename bitmap_size() -> idset_bitmap_size()
fs/ntfs3: add prefix to bitmap_size() and use BITS_TO_U64()
btrfs: rename bitmap_set_bits() -> btrfs_bitmap_set_bits()
tools: move alignment-related macros to new <linux/align.h>
bitmap: introduce generic optimized bitmap_size()
bitmap: make bitmap_{get,set}_value8() use bitmap_{read,write}()
lib/bitmap: add compile-time test for __assign_bit() optimization

>From v2[2]:
* 00: drop ip_tunnel part: will be sent together with the PFCP part once
this gets accepted (Jakub, Yury);
* 02: fix format string literal build warning due to the new generic
macro having different implicit type (Stephen);
* 04: pick Acked-by (Jakub);
* 08: new;
* 09: pick Acked-by (Yury), fix including the header not existing under
the tools/ tree (via #8) (Stephen);.
>From v1[3]:
* 03: convert assign_bit() to a macro as well, saves some bytes and
looks more consistent (Yury);
* 03: enclose each argument into own pair of braces (Yury);
* 06: use generic BITS_TO_U64() while at it (Yury);
* 07: pick Acked-by (David);
* 08: Acked-by, use bitmap_size() in the code from 05 as well (Yury);
* 09: instead of introducing a new pair of functions, use generic
bitmap_{read,write}() from [0]. bloat-o-meter shows no regressions
from the switch (Yury, also Andy).
Old pfcp -> bitmap changelog:
As for former commits (now 10 and 11), almost all of the changes were
suggested by Andy, notably: stop violating bitmap API, use
__assign_bit() where appropriate, and add more tests to make sure
everything works as expected. Apart from that, add simple wrappers for
bitmap_*() used in the IP tunnel code to avoid manually specifying
``__IP_TUNNEL_FLAG_NUM`` each time.
