[Kleber Sacilotto de Souza]

BugLink: https://bugs.launchpad.net/bugs/1877123

[Impact]
The build of qemu and other userspace broke because of the following patch
applied to bionic as part of one of the upstream stable updates:

    uapi: rename ext2_swab() to swab() and share globally in swab.h

    BugLink: https://bugs.launchpad.net/bugs/1874502

    [ Upstream commit d5767057c9a76a29f073dad66b7fa12a90e8c748 ]

The affected header file is shipped by the linux-libc-dev package.

[Fix]
The fix has already been applied on mainline and the stable trees and
can be cherry-picked to bionic/linux.

    include/uapi/linux/swab.h: fix userspace breakage, use __BITS_PER_LONG for swap

[Testcase]
Install linux-libc-dev and build qemu.

[Regression Potential]
Low. The fix is simple and has already landed on upstream stable, with no
follow-up fix so far on mainline.
