#     
#     Pull RAS fixes from Thomas Gleixner:
#      "Two fixes for the AMD MCE driver:
#     
#        - Populate the per CPU MCA bank descriptor pointer only after it has
#          been completely set up to prevent a use-after-free in case that one
#          of the subsequent initialization step fails
#     
#        - Implement a proper release function for the sysfs entries of MCA
#          threshold controls instead of freeing the memory right in the CPU
#          teardown code, which leads to another use-after-free when the
#          associated sysfs file is opened and accessed"
