Subject: [PATCH v3 0/4] perf: Remove libcrypto dependency

This is a reworked version of
https://lore.kernel.org/all/20250521225307.743726-1-yuzhuo@google.com/.
I've changed it to add a new minimal SHA-1 implementation, instead of
trying to pull in the kernel's SHA-1 implementation which is not really
designed to be extracted into userspace programs.  I also added a test.

Changed in v3:
   - Rebased onto perf-tools-next
   - Removed unnecessary parentheses in array indices in sha1.c
   - Updated my email address.  I've started consistently using my
     kernel.org email address.

Eric Biggers (2):
  perf build: enable -fno-strict-aliasing
  perf util: add a basic SHA-1 implementation

Yuzhuo Jing (2):
  perf genelf: Remove libcrypto dependency and use built-in sha1()
  tools: Remove libcrypto dependency
