x86, mce: add basic error injection infrastructure
Allow user programs to write mce records into /dev/mcelog. When they do
that a fake machine check is triggered to test the machine check code.
This uses the MCE MSR wrappers added earlier.
The implementation is straight forward. There is a struct mce record
per CPU and the MCE MSR accesses get data from there if there is valid
data injected there. This allows to test the machine check code
relatively realistically because only the lowest layer of hardware
access is intercepted.
The test suite and injector are available at
