Subject: mm: remove VM_EXEC requirement for THP eligibility
Date: Tue, 19 Dec 2023 21:41:23 -0800

Commit e6be37b2e7bd ("mm/huge_memory.c: add missing read-only THP checking
in transparent_hugepage_enabled()") introduced the VM_EXEC requirement,
which is not strictly needed.

lld's default --rosegment option and GNU ld's -z separate-code option
(default on Linux/x86 since binutils 2.31) create a read-only PT_LOAD
segment without the PF_X flag, which should be eligible for THP.

Certain architectures support medium and large code models, where .lrodata
may be placed in a separate read-only PT_LOAD segment, which should be
eligible for THP as well.
