  This series does a cleanup of all ENTRY()/END() macros that are used in
arch/riscv/ as well as use of local labels. This allows to remove the
use of the now deprecated ENTRY()/END()/WEAK() macros as well as using
the new SYM_*() ones which provide a better understanding of what is
meant to be annotated. Some wrong usage of SYM_FUNC_START() are also
fixed in this series by using the correct annotations. Finally a few
labels that were meant to be local have been renamed to use the .L
suffix and thus not to be emitted as visible symbols.

Note: the patches have been split between arch/riscv/ and
arch/riscv/kvm/ due to having different maintainers.

---

Changes in V2:
 - Remove duplicated SYM_FUNC_END(memmove)
 - Use SYM_DATA for simple .quad usage
 - Added Andrew Rb:

Clément Léger (5):
  riscv: use ".L" local labels in assembly when applicable
  riscv: Use SYM_*() assembly macros instead of deprecated ones
  riscv: kernel: Use correct SYM_DATA_*() macro for data
  riscv: kvm: Use SYM_*() assembly macros instead of deprecated ones
  riscv: kvm: use ".L" local labels in assembly when applicable
