Fix two bugs in two test cases.
1) In the test for disk file soft off-line, it often fails
because it is mmaped via shared mode. Now chaning it
to private mode to fix wider test environment.
2) in run_soft.sh there is one spell mistake so that some
test case will fail.

After a successful hugetlb page migration by soft offline, the source
page will either be freed into hugepage_freelists or buddy
(over-commit page). If page is in buddy, page_hstate(page) will be
NULL. It will hit a NULL pointer dereference in
dequeue_hwpoisoned_huge_page().

tinjpage and ttranshuge can get SIGCHLD(CLD_DUMPED) from their child
processes, but now they only check CLD_KILLED, so tests fail.
This behavior of the kernel might not be wrong, because the defalut
action of the SIGBUS is 'coredump', not 'terminate' (see comments in
include/linux/signal.h).
With this patch, we accept SIGCHLD(CLD_DUMPED) as a correct behavior.

Code displacement:
- moved common code into helper.sh to avoid duplicates,
- merged run-huge-test.sh into run_hugepage.sh and
run-transhuge-test.sh into run_thp.sh.
Minor improvements:
- added sysctl vm.memory_failure_early_kill=0 in the setup of each
testcase (some testcases change this global parameter, so it's safe
to reset it to 0 to avoid interference between testcases),
- added freeing resources (shmems, semaphores) and unpoisoning
in the cleanup of each testcase,
- added counter check ("HardwareCorrupted:" in /proc/meminfo)

The addr of write/read_hugepage() is the mapping address of file.
So no matter how many hugepages are mapped, addr will be
the head address of all hugepages.
The avoid of write/read_hugepage() is the address which does not
want to be touched. So it could be the head address of any hugepage.
So addr == avoid in write/read_hugepage() is not equal always except
the avoid is the address of the first hugepage.

added clearing and backing up old logs for kdump driver. As testcases causes

Second one is with loading mce-inject module. The kdump test driver is
appereantly run with "set -ex" so all lines that can return non zero (and

This patch adds the testcases for mmap/IPV shared pages.
The purpose of these testcases is as follows:
- We can check whether a process A is killed expectedly when it accesses
the page shared with and hwpoisoned by another process B
(in the late killing case).
- We can check whether a process A is killed at once when another process B
injected hwpoison into the page shared by both of them
(in the early killing case).
ChangeLog:
- Add synchronization code between parent and child process with semaphore.
- Share the common function do_shared() between mmap case and IPV case.
- Add error chack code.

It is the fs-metadata workload. fs-metadata is designed to test i-node
operations with heavy workload and make sure every i-node operation gets
the expected result. In details, it firstly generates a huge directory
hierarchy on the target disk, then it performs unlink operations on this
directory hierarchy and duplicate a copy of the directory, finally it
checks if these two directories are same as expected.

page-poisoning test program is an extension of tinjpage test program with a
multi-process model. It spawns thousands of processes that inject HWPosion
error to various pages simultaneously thru madvise syscall. Then it checks
if these errors get handled correctly, i.e. whether each test process
receives or doesn't receive SIGBUS signal as expected.
In details, page-poisoning is designed to cover all of possible userspace page
types via following two test operations:
- anonymous pages operations.
- file data operations.

The MCE stress test suite is a collection of tools and test scripts, which
intends to achieve stress testing for Linux kernel MCA high level handlers
that include HWPosion page recovery, soft page offline, and so on.
In general, this test suite is designed to do stress testing thru various
test interfaces, i.e. madvise syscall, HWPoison page injector, and APEI
injector (see ACPI4.0 spec). And it's able to support most of popular
Linux File Systems (FS), that is, there is an option for user to specify which
FS type they want the test to be running on.
The MCE stress test suite consists of four parts: test driver, workload
controller, customized workloads, and background workloads.
The main test idea is described as below:
- Test driver launchs various customized workloads to continuously generate
lots of pages with expected page states, Note, all of these workloads know
about their expected results that should not be affected by Linux MCE high
level handlers.
- Then test driver injects MCE errors to these pages thru either madvise
syscall or HWPoison injector or APEI injector. While Linux Kernel handling
these MCE errors, all the workloads continue running normally,
- After long time running, test driver will collect test result of each
workload to see if any unexpected failures happened. In such a way, it can
decide if any bug is found.
- If any system panics or FS corruption happens, that means there must be a
bug. It's the bottom line to decide if test gets pass.
Test driver (a.k.a hwpoison.sh) drives the whole test procedure. It's
responsible for managing test environment, setting up error injection
interface, controlling test progress, launching workloads, injecting page
errors, as well as recordng test logs and reportng test result.
