[kvm-unit-tests,v6,0/5] riscv: add SBI SSE extension tests

Message

This series adds an individual test for SBI SSE extension as well as
needed infrastructure for SSE support. It also adds test specific
asm-offsets generation to use custom OFFSET and DEFINE from the test
directory.

---

V6:
 - Add missing $(generated-file) dependencies for "-deps" objects
 - Split SSE entry from sbi-asm.S to sse-asm.S and all SSE core functions
   since it will be useful for other tests as well (dbltrp).

V5:
 - Update event ranges based on latest spec
 - Rename asm-offset-test.c to sbi-asm-offset.c

V4:
 - Fix typo sbi_ext_ss_fid -> sbi_ext_sse_fid
 - Add proper asm-offset generation for tests
 - Move SSE specific file from lib/riscv to riscv/

V3:
 - Add -deps variable for test specific dependencies
 - Fix formatting errors/typo in sbi.h
 - Add missing double trap event
 - Alphabetize sbi-sse.c includes
 - Fix a6 content after unmasking event
 - Add SSE HART_MASK/UNMASK test
 - Use mv instead of move
 - move sbi_check_sse() definition in sbi.c
 - Remove sbi_sse test from unitests.cfg

V2:
 - Rebased on origin/master and integrate it into sbi.c tests

Clément Léger (5):
  kbuild: allow multiple asm-offsets file to be generated
  riscv: use asm-offsets to generate SBI_EXT_HSM values
  riscv: Add "-deps" handling for tests
  riscv: lib: Add SBI SSE extension definitions
  riscv: sbi: Add SSE extension tests
