[PATCH v2 4/4] alpha: Use absolute_pointer to define COMMAND_LINE

From: Guenter Roeck
Date: Tue Sep 14 2021 - 23:53:02 EST


alpha:allmodconfig fails to build with the following error
when using gcc 11.x.

arch/alpha/kernel/setup.c: In function 'setup_arch':
arch/alpha/kernel/setup.c:493:13: error:
'strcmp' reading 1 or more bytes from a region of size 0

Avoid the problem by declaring COMMAND_LINE as absolute_pointer().
