H A DMakefile.extrawarndiff 1344794a59db2bd44b4919d2d75300fd3b1c2cd7 Tue Mar 08 22:56:12 CET 2022 Arnd Bergmann <arnd@arndb.de> Kbuild: add -Wno-shift-negative-value where -Wextra is used

As a preparation for moving to -std=gnu11, turn off the
-Wshift-negative-value option. This warning is enabled by gcc when
building with -Wextra for c99 or higher, but not for c89. Since
the kernel already relies on well-defined overflow behavior,
the warning is not helpful and can simply be disabled in
all locations that use -Wextra.
