[kvm-unit-tests PATCH 0/8] arm: fix building by adding a feature

[Andrew Jones <drjones@redhat.com>]

The main motivator of this series is to get the arm build fixed.
522667917 "lib: backtrace printing" added a common backtrace()
function, but we missed that arm's __builtin_return_address only
accepts the input 0, and thus the function, which calls it with
all values 0 to 20, can't compile on arm. To fix backtrace() for
arm, the easiest thing to do is to override it with a backtrace
that works. So this series makes some cleanups to stack tracing
support and adds the support for ARM.


Andrew Jones (8):
  x86: change exit to abort again
  x86: trivial: there's no dump_stack.o
  pretty_print_stacks: keep the 'STACK:' line
  pretty_print_stacks: use elf file for the kernel
  pretty_print_stacks: addr2line may need a cross prefix
  stack: share api prototypes
  stack: copy common asm/stack.h bits to all arches
  arm: stack: add dump_stack support
