#     x86/bugs: Fix the SRSO mitigation on Zen3/4
#     
#     The original version of the mitigation would patch in the calls to the
#     untraining routines directly.  That is, the alternative() in UNTRAIN_RET
#     will patch in the CALL to srso_alias_untrain_ret() directly.
#     
#     However, even if commit e7c25c441e9e ("x86/cpu: Cleanup the untrain
#     mess") meant well in trying to clean up the situation, due to micro-
#     architectural reasons, the untraining routine srso_alias_untrain_ret()
#     must be the target of a CALL instruction and not of a JMP instruction as
#     it is done now.
#     
#     Reshuffle the alternative macros to accomplish that.
#     
#     Fixes: e7c25c441e9e ("x86/cpu: Cleanup the untrain mess")
