Vineet Gupta b08861d10b asm-generic/tlb: stub out pud_free_tlb() if nopud ... ... ... independent of __ARCH_HAS_4LEVEL_HACK This came up when removing __ARCH_HAS_5LEVEL_HACK for ARC as code bloat. With this patch we see the following code reduction | bloat-o-meter2 vmlinux-B-elide-ARCH_USE_5LEVEL_HACK vmlinux-C-elide-pud_free_tlb | add/remove: 0/0 grow/shrink: 0/1 up/down: 0/-104 (-104) | function old new delta | free_pgd_range 656 552 -104 | Total: Before=4137276, After=4137172, chg -1.000000% Note: The primary change is alternate defintion for pud_free_tlb() but while there also removed empty stubs for __pud_free_tlb, which is anyhow called only from pud_free_tlb() Link: http://lkml.kernel.org/r/20191016162400.14796-3-vgupta@synopsys.com Signed-off-by: Vineet Gupta <vgupta@synopsys.com> Acked-by: Kirill A.
