Subject: mm: fix xyz_noprof functions calling profiled functions
Date: Fri, 31 May 2024 13:53:50 -0700

Grepping /proc/allocinfo for "noprof" reveals several xyz_noprof
functions, which means internally they are calling profiled functions. 
This should never happen as such calls move allocation charge from a
higher level location where it should be accounted for into these lower
level helpers.  Fix this by replacing profiled function calls with noprof
ones.
