# commit a048a07d7f4535baa4cbad6bc024f175317ab938 upstream. # # On some CPUs we can prevent a vulnerability related to store-to-load # forwarding by preventing store forwarding between privilege domains, # by inserting a barrier in kernel entry and exit paths. # # This is known to be the case on at least Power7, Power8 and Power9 # powerpc CPUs. # # Barriers must be inserted generally before the first load after moving # to a higher privilege, and after the last store before moving to a # lower privilege, HV and PR privilege transitions must be protected. # # Barriers are added as patch sections, with all kernel/hypervisor entry # points patched, and the exit points to lower privilge levels patched # similarly to the RFI flush patching. # # Firmware advertisement is not implemented yet, so CPU flush types # are hard coded. # # Thanks to Michal Suchánek for bug fixes and review. #
