Subject: [PATCH] tests: Align THP tests to the 32MB huge-page size
Date: Wed, 22 Jul 2026 04:01:38 +0800	[thread overview]
Message-ID: <20260721200148.1706264-1-xry111@xry111.site> (raw)

On MIPS64 and AArch64 systems with 16-KiB pages, the PMD size is 32MB.
As we already have multiple platforms requiring such a large size, it
seems easier to raise the default instead of adding more special cases.

Link: https://sourceware.org/glibc/wiki/Testing/Tests/elf/tst-thp-1
Signed-off-by: Xi Ruoyao <xry111@xry111.site>
---

Tested on x86_64-linux and mips64-linux.
