-Subject: [PATCH 6/8] x86/setup: remove CONFIG_X86_RESERVE_LOW and reservelow
- options
-
-The CONFIG_X86_RESERVE_LOW build time and reservelow command line option
-allowed to control the amount of memory under 1M that would be reserved at
-boot to avoid using memory that can be potentially clobbered by BIOS.
-
-Since the entire range under 1M is always reserved there is no need for
-these options and they can be removed.

-- help
-- Specify the amount of low memory to reserve for the BIOS.
--
-- The first page contains BIOS data structures that the kernel
-- must not use, so that page must always be reserved.
--
-- By default we reserve the first 64K of physical RAM, as a
-- number of BIOSes are known to corrupt that memory range
-- during events such as suspend/resume or monitor cable
-- insertion, so it must not be used by the kernel.
--
-- You can set this to 4 if you are absolutely sure that you
-- trust the BIOS to get all its memory reservations and usages
-- right. If you know your BIOS have problems beyond the
-- default 64K area, you can set this to 640 to avoid using the
-- entire low memory range.
--
-- If you have doubts about the BIOS (e.g. suspend/resume does
-- not work or there's kernel crashes after certain hardware
-- hotplug events) then you might want to enable
-- X86_CHECK_BIOS_CORRUPTION=y to allow the kernel to check
-- typical corruption patterns.
--
-- Leave this to the default value of 64 if you are unsure.
