Subject[PATCH] m68k: Drop -fno-strength-reduce from KBUILD_CFLAGS
Date
This workaround became redundant either when the driver in question was
removed (in Linux v2.6.23) or when the compiler flag became a no-op
(in GCC v4.2). Linux has required GCC v4.6 or later since v4.19.

References: commit cafa0010cd51 ("Raise the minimum required gcc version to 4.6")
