Kernel 2.4.6 does not compile on Sparc

[fabrizio.gennari@philips.com]

We have a problem with kernel 2.4.6 on a Sparc. It seems that pgalloc.h defines as macros some identifiers which are defined elsewhere as functions, with a different number of args. Those are pte_alloc (defined in memory.c) and pmd_alloc (defined in
mm.h). It is the same problem as Alex Buell has, as he wrote on May 9th:

Has anyone got a patch to fix the following error when compiling
2.4.4 on SparcStation 4?
