[PATCH 00/11] treewide: Fix a bunch of shift overflows

[Borislav Petkov]

From: Borislav Petkov <bp@xxxxxxx>

Hi all,

so this is the result of me trying to make allmodconfig actually build
here.

Due to some recent changes which added -fsanitize-shift to the build
options of an allmodconfig, it started failing here with an old gcc
because getting an overflow while shifting is undefined C99 behavior.

gcc warns/errors out with -Werror about this only on newer versions
where -pedantic is present while older ones do so even without it. The
whole details here:

  https://lore.kernel.org/r/YkwQ6%2BtIH8GQpuct@xxxxxxx

Fixing all those is trivial so please pick up at your convenience.

In order to avoid spamming people unnecessarily, I'm not CCing everyone
on each patch but only the relevant maintainers and lists.

Thx.
