tools/tests: Drop obsolete mce-test infrastructure

Browse Source 
mce-test has a test suite, but it depends on xend, needs to run in-tree, and
requires manual setup of at least one guest, and manual parameters to pass
into cases.  Drop the test infrasturcture.

Move the one useful remaining item, xen-mceinj, into misc/, fixing some minor
style issues as it goes.

Xen MCE test suite
---------------
The Xen MCE test suite is a collection of tools and test scripts for
testing the Xen MCE processing features. The goal is to cover
most Xen MCE processing code paths and features with automation tests.
In the Package
--------------
Here is a short description of what is included in the package
README
This is document
Makefile
For compile
cases/*
Contains all test cases, which may be organized in sub-directories,
the interface of test case is a shell script under cases/, such as:
-- cases/srao_mem/dom0/cases.sh
config/*
Contains test configuration files, which specifies the parameters
for test cases, etc.
lib/*
Contains some shell scripts, in which some common shell
functions and variable definitions are defined to be used by
test cases.
tools/*
Tools used by MCE test suites, now only xen-mceinj tool.
results/
When test is done, the test result will be placed in this
directory, test results of various cases may be in corresponding
directory.
For example, files in
results/srao_mem_dom0/result
is the result for test case cases/srao_mem/dom0/cases.sh, there will
be 3 result conditions: PASSED/FAILED/NORESULT.
results/<test_case>/testlog #the test log during testing
results/<test_case>/mcelog #mcelog output during testing
results/<test_case>/xenlog #Xen log during testing
results/<test_case>/gklog #VM guest kernel log during testing
results/<test_case>/guest_config #config file used to create guest
Test Instruction
----------------
1. make sure you have a dom0 with mce support
CONFIG_X86_MCE=y
CONFIG_X86_MCE_INTEL=y
CONFIG_X86_MCE_AMD=y
CONFIG_X86_MCE_THRESHOLD=y
CONFIG_X86_MCE_INJECT=y
2. run system at xen and start xend. A installed guest image is
necessary when do guest MCE error injection.
3. compile tools that used to test. in mce-test, $make.
Note: make sure compile xen/tools before do this step
4. run test cases that you want.
e.g. $sh cases/srao_mem/dom0/cases.sh -d 0 -p 0x0200 -c 2 -t 1
5. get test result in results directory
Notes
----------------
All test cases fake a error and inject this error in 0x180020, For Xen
test cases(e.g. cases/srao_mem/xen/cases.sh), error happen on every page
may cause a Xen panic.

Xen Machine Check Exception(MCE) error inject tool
----------------------------------------------
xen-mceinj is a software MCE injection tool, which is based on Xen
MCE injection mechanism. It allows to inject machine check errors on the
software level into a running Xen/dom0/VM. This is intended for
validation of the Xen machine check handler.
With the help of the Makefile, it is possible to compile a binary file
named "xen-mceinj".
Usage
-----
$make (make install) --Note: make sure compile xen/tools before do this step
$./xen-mceinj [OPTION]...
OPTION arguments can be:
-D, --dump dump addr info without error injection
-c, --cpu=CPU_ID target CPU, the default is CPU0
-d, --domain=DomID target domain, the default is Xen itself
-p, --page physical page address, the default is 0x180020
-t, --type=error error type
For detail help, please refer to "./xen-mceinj -h"
