The patch titled
Subject: Kconfig: remove HAVE_LATENCYTOP_SUPPORT
has been removed from the -mm tree. Its filename was
kconfig-remove-have_latencytop_support.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: Will Deacon <will.deacon@xxxxxxx>
Subject: Kconfig: remove HAVE_LATENCYTOP_SUPPORT
As illustrated by a3afe70b83fd ("[S390] latencytop s390 support."),
HAVE_LATENCYTOP_SUPPORT is defined by an architecture to advertise an
implementation of save_stack_trace_tsk.
However, as of 9212ddb5eada ("stacktrace: provide save_stack_trace_tsk()
weak alias") a dummy implementation is provided if STACKTRACE=y. Given
that LATENCYTOP already depends on STACKTRACE_SUPPORT and selects
STACKTRACE, we can remove HAVE_LATENCYTOP_SUPPORT altogether.
