There are some ABI documents that, while they don't generate any warnings, they have issues when parsed by get_abi.pl script on its output result. Address them, in order to provide a clean output.

Description:
|
|
The /sys/devices/system/memory contains a snapshot of the
|
|
internal state of the kernel memory blocks. Files could be
|
|
added or removed dynamically to represent hot-add/remove
|
|
operations.

|
|
Description:
|
|
The file /sys/devices/system/memory/memoryX/removable
|
|
indicates whether this memory block is removable or not.
|
|
This is useful for a user-level agent to determine
|
|
identify removable sections of the memory before attempting
|
|
potentially expensive hot-remove memory operation

Description:
|
|
The file /sys/devices/system/memory/memoryX/phys_device

is read-only and is designed to show the name of physical

Description:
|
|
The file /sys/devices/system/memory/memoryX/phys_index

is read-only and contains the section ID in hexadecimal
|
|
which is equivalent to decimal X contained in the

|
Description:
|
|
The file /sys/devices/system/memory/memoryX/state
|
|
is read-write. When read, its contents show the
|
|
online/offline state of the memory section. When written,
|
|
root can toggle the the online/offline state of a removable
|
|
memory section (see removable file description above)
|
|
using the following commands::
|
|
|
|
# echo online > /sys/devices/system/memory/memoryX/state
|
|
# echo offline > /sys/devices/system/memory/memoryX/state
|
|
|
|
For example, if /sys/devices/system/memory/memory22/removable
|
|
contains a value of 1 and
|
|
/sys/devices/system/memory/memory22/state contains the
|
|
string "online" the following command can be executed by
|
|
by root to offline that section::
|
|
|
|
# echo offline > /sys/devices/system/memory/memory22/state
