Its filename was mips-kdb-remove-old-workaround-for-backtracing-on-other-cpus.patch This patch was dropped because it was merged into mainline or a subsystem tree ------------------------------------------------------ From: Douglas Anderson Subject: MIPS: kdb: remove old workaround for backtracing on other CPUs Patch series "kdb: Don't implicitly change tasks; plus misc fixups". This patch (of 5): As of commit 2277b492582d ("kdb: Fix stack crawling on 'running' CPUs that aren't the master") we no longer need any special case for doing stack dumps on CPUs that are not the kdb master. Let's remove. Link: http://lkml.kernel.org/r/20191109111623.1.I30a0cac4d9880040c8d41495bd9a567fe3e24989@changeid Signed-off-by: Douglas Anderson Cc: Chong Qiao Cc: Daniel Thompson Cc: Eric W.
