This has now been changed to.. #define pte_free(pte) pte_free_fast(pte) The code that follows this is interesting though.. #ifdef CONFIG_X86_PAE #define pgd_alloc(mm) get_pgd_slow() #define pgd_free(pgd) free_pgd_slow(pgd) #else #define pgd_alloc(mm) get_pgd_fast() #define pgd_free(pgd) free_pgd_fast(pgd) #endif Anyone want to elaborate why PAE means we frob pgd's the slow way? regards, Dave. -- -ENOMONKEY. -- Kernelnewbies: Help each other learn about the Linux kernel.
