From: Masayoshi Mizuma <[email protected]> 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.
