[LTP] [LTP PATCH v1 0/1] Add some memory page soft-offlining control

[William Roche]

This patch is offering a new test to the LTP test suite to control the behavior
of the memory page soft-offlining: its goal is to stress the soft-offlining
mechanism while allocating memory. It verifies the content of a memory address
after a Soft-offline, and tries to reproduce the coditions of a race condition
where newly allocated page could generate a SIGBUS when touched.
(See Kernel upstream commit d4ae9916ea29 "mm: soft-offline: close the race against page allocation")

It is inspired by the existing memory allocation test:
testcases/kernel/mem/mtest07/mallocstress.c

Code tested on ARM and x86.
