Revision 632a1c209b8773cb0119fe3aada9f1db14fa357c authored by Thomas Tai on 08 April 2021, 17:28:33 UTC, committed by Borislav Petkov on 09 April 2021, 11:45:09 UTC
Commit
334872a09198 ("x86/traps: Attempt to fixup exceptions in vDSO before signaling")
added return statements which bypass calling cond_local_irq_disable().
According to
ca4c6a9858c2 ("x86/traps: Make interrupt enable/disable symmetric in C code"),
cond_local_irq_disable() is needed because the asm return code no longer
disables interrupts. Follow the existing code as an example to use "goto
exit" instead of "return" statement.
