This series was originally part of the series ("serial: Finish kgdb on
qcom_geni; fix many lockdep splats w/ kgdb") but it made sense to
split it up.
It's believed that dropping into kgdb should be more robust once these
patches are applied.
Changes in v3:
- No separate init call.
- Don't round up the CPU that is doing the rounding up.
- Add "#ifdef CONFIG_SMP" to match the rest of the file.
- Updated desc saying we don't solve the "failed to roundup" case.
- Document the ignored parameter.
- Patch #3 and #4 are new.
Changes in v2:
- Removing irq flags separated from fixing lockdep splat.
- Removing irq flags separated from fixing lockdep splat.
- Don't use smp_call_function (Daniel).
Douglas Anderson (4):
kgdb: Remove irq flags from roundup
kgdb: Fix kgdb_roundup_cpus() for arches who used smp_call_function()
kgdb: Don't round up a CPU that failed rounding up before
kdb: Don't back trace on a cpu that didn't round up
