5.4-stable review patch. If anyone has any objections, please let me know.

From: Paul Menzel pmenzel@molgen.mpg.de
[ Upstream commit ad7c3c0cb8f61d6d5a48b83e62ca4a9fd2f26153 ]
Currently, the code does:
if (x == 0) { x &= ~0x3; x |= 0x1; }
Zeroing bits 0 and 1 of a variable that is 0 is not necessary. So directly set the variable to 1.
