Josh Poimboeuf 931b6bfe8a x86/entry/64: Use JMP instead of JMPQ ... commit 64dbc122b2 upstream Somehow the swapgs mitigation entry code patch ended up with a JMPQ instruction instead of JMP, where only the short jump is needed. Some assembler versions apparently fail to optimize JMPQ into a two-byte JMP when possible, instead always using a 7-byte JMP with relocation. For some reason that makes the entry code explode with a #GP during boot. Change it back to "JMP" as originally intended.
