[folded-merged] mm-vmalloc-enable-memory-allocation-profiling-fix.patch removed from -mm tree

[Andrew Morton]

The quilt patch titled
     Subject: arch/um: fix forward declaration for vmalloc
has been removed from the -mm tree.  Its filename was
     mm-vmalloc-enable-memory-allocation-profiling-fix.patch

This patch was dropped because it was folded into mm-vmalloc-enable-memory-allocation-profiling.patch

Subject: arch/um: fix forward declaration for vmalloc
Date: Tue, 26 Mar 2024 00:37:50 -0700

Patch [1] replaced vmalloc() function with a new definition but it did not
adjust the forward declaration used in UML architecture.  Change it to act
as before.

Note that this prevents the vmalloc() allocations in __wrap_malloc() from
being accounted.  If accounting here is critical, we will have to remove
this forward declaration and include vmalloc.h, however that would pull in
more dependencies and would require introducing more architecture-specific
headers, like asm/bug.h, asm/rwonce.h, etc.  This is likely the reason why
this forward declaration was introduced in the first place.
