Huang Ying 76da3fb357 ACPI, Add RAM mapping support to ACPI atomic IO support 
On one of our testing machine, the following EINJ command lines:

  # echo 0x10000000 > param1
  # echo 0xfffffffffffff000 > param2
  # echo 0x8 > error_type
  # echo 1 > error_inject

Will get:

  echo: write error: Input/output error

The EIO comes from:

    rc = apei_exec_pre_map_gars(&trigger_ctx);

The root cause is as follow.  Normally, ACPI atomic IO support is used
to access IO memory.  But in EINJ of that machine, it is used to
access RAM to trigger the injected error.  And the ioremap() called by
apei_exec_pre_map_gars() can not map the RAM.

This patch add RAM mapping support to ACPI atomic IO support to
satisfy EINJ requirement.
