Subject: mm: fixup very disguised vmalloc flags parameter
Date: Tue, 29 Jul 2025 13:48:50 +0100

The declare_vma() function in arm64 arch code liberally mixes the concepts
of VMAs and near-identically named vmalloc data structures, so I
accidentally changed the 'vm_flags' field' that is assigned to a 'vma'
thinking it was... the vm_flags field of a vma, which it turns out, it
isn't.

Revert the type from vm_flags_t to unsigned long.

Given vm_flags_t == unsigned long, there is no change in any behaviour
before or after this patch, but in future this will matter.
