linux.git/arch/mips/kernel/genex.S, branch v2.6.22 Linux kernel source tree [MIPS] lockdep: Deal with interrupt disable hazard in TRACE_IRQFLAGS 2007-03-29T22:46:35+00:00 Chris Dearman chris@mips.com 2007-03-26T13:48:50+00:00 fe99f1b184efb75c50dd8cbdfff99b559c2cb3b3 Between the mtc0 or di instruction that disables interrupts and the following hazard barrier a processor may still take interrupts. If an interrupt is taken after interrupts are disabled but before the state is updated it will appear to restore_all that it is incorrectly returning with interrupts disabled.

Between the mtc0 or di instruction that disables interrupts and the
following hazard barrier a processor may still take interrupts.  If an
interrupt is taken after interrupts are disabled but before the state
is updated it will appear to restore_all that it is incorrectly returning
with interrupts disabled.
