Hi,

2.6.24-mm1 won't build if CONFIG_X86_PAE is defined:


/home/lkernel/src/linux-2.6.24-mm1/arch/x86/mm/pgtable_32.c: In function 
‘pgd_mop_up_pmds’:
/home/lkernel/src/linux-2.6.24-mm1/arch/x86/mm/pgtable_32.c:302: 
warning: passing argument 1 of ‘pmd_free’ from incompatible pointer type
/home/lkernel/src/linux-2.6.24-mm1/arch/x86/mm/pgtable_32.c:302: error: 
too few arguments to function ‘pmd_free’
make[2]: *** [arch/x86/mm/pgtable_32.o] Error 1
make[1]: *** [arch/x86/mm] Error 2
make: *** [sub-make] Error 2


You'll find the proposed patch in attachment.

Regards,
Nadia

Add the mm missing argument to pmd_free() calls.
