Subject: Configure: set cache line size for loongarch64
X-Git-Url: http://git.kaiwu.me/postgresql/log/contrib/postgres_fdw/stylesheets/print.css?a=commitdiff_plain;h=be84ac8bda2265d254f3ead9c3f0ba1d78a79319;p=nginx.git

Configure: set cache line size for loongarch64

Section 8.2 table 54, registers 0x11 - 0x14 (2^6 = 64 bytes)
<https://loongson.github.io/LoongArch-Documentation/Loongson-3A5000-usermanual-EN.html#instruction-set-features-implemented-in-3a5000>

There is no intent to cover 32-bit LoongArch which acceptably falls
through to the default.
