Subject[PATCH 2/2] docs: kernel-parameters.txt: document rand_mem_physical_padding parameter
Date
From: Masayoshi Mizuma <m.mizuma@jp.fujitsu.com>

This kernel parameter allows to change the padding used for the physical
memory mapping section when KASLR memory is enabled.

For some systems, the default value, CONFIG_RANDOMIZE_MEMORY_PHYSICAL_PADDING,
is not enough. The option is useful to adjust the padding size to work
around such issue.
