Subject: x86/boot: properly "ignore" early evaluated "no-real-mode"
X-Git-Tag: archive/raspbian/4.16.0+51-g0941d6cb-1+rpi1~2^2~42^2~194

x86/boot: properly "ignore" early evaluated "no-real-mode"

The option parser takes off "no-" prefixes before matching, so they also
shouldn't be specified to match against.

Fixes: e44d98608476 ("x86/setup: Ignore early boot parameters like no-real-mode")
