Subject: mm: vmalloc: enable memory allocation profiling
Date: Thu, 21 Mar 2024 09:36:52 -0700

This wrapps all external vmalloc allocation functions with the
alloc_hooks() wrapper, and switches internal allocations to _noprof
variants where appropriate, for the new memory allocation profiling
feature.
