[PATCH 1/1] arch/um: fix forward declaration for vmalloc

[Suren Baghdasaryan]

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.
