Message-ID: <20261102170202.24963-2-kaloz@kernel.org>

Subject: [PATCH 1/2] add 32-bit sparc (V8) port
The objects are V8 except casa, which is emitted as a word, with its
ASI chosen from AT_HWCAP at startup. PAGESIZE is not defined, since
pages are 4K on V8 hardware and 8K under a 64-bit kernel. The sparc64
hooks are used, except ipc and suseconds_t.
