Re: 2.6.24-mm1 Build Faliure on pgtable_32.c

[Kamalesh Babulal <kamalesh@linux.vnet.ibm.com>]

Hi Andrew,

The 2.6.24-mm1 kernel build fails with 

arch/x86/mm/pgtable_32.c: In function `pgd_mop_up_pmds':
arch/x86/mm/pgtable_32.c:302: warning: passing arg 1 of `pmd_free' from incompatible pointer type
arch/x86/mm/pgtable_32.c:302: error: too few arguments to function `pmd_free'

I have tested the patch for the build failure only.
