From: "Kiryl Shutsemau (Meta)" <kas@kernel.org>
Subject: x86/vdso: undefine CONFIG_HUGETLB_PAGE_OPTIMIZE_VMEMMAP for vdso32
Date: Fri, 27 Feb 2026 19:42:49 +0000

The 32-bit VDSO build on x86_64 uses fake_32bit_build.h to undefine
various kernel configuration options that are not suitable for the VDSO
context or may cause build issues when including kernel headers.

Undefine CONFIG_HUGETLB_PAGE_OPTIMIZE_VMEMMAP in fake_32bit_build.h to
prepare for change in HugeTLB Vmemmap Optimization.
