[PATCH -mm v7 01/13] mm/pagewalk: remove pgd_entry() and pud_entry()

Currently no user of page table walker sets ->pgd_entry() or ->pud_entry(), so checking their existence in each loop is just wasting CPU cycle. So let's remove it to reduce overhead. Signed-off-by: Naoya Horiguchi Acked-by: Kirill A. Shutemov --- include/linux/mm.h | 6 -- mm/pagewalk.c

[PATCH 1/3] perf tools: Allow vmlinux to fallback to kallsyms on NO_LIBELF=1

When libelf is not used, perf cannot not show symbol names since it doesn't access the ELF symbol table. But kernel is different as it can fallback to kallsyms. It worked w/o libelf, but recent change to use vmlinux for kernel symbols break it. With this change, it now can show kernel symbols

[PATCH 2/3] perf symbol: Implement a very simple ELF symbol parser

It'll be used to show (userspace) symbol names when libelf isn't (or cannot be) linked. # Overhead Command Shared Object Symbol # .. . . # 37.01% mem-memcpy libc-2.17.so [.] __memcpy_ssse3_back 24.25%

[PATCH 3/3] perf tools: Clean up libelf feature support code

Current EXTLIBS contains -lelf by default and removes it when libelf is not detected. This is little bit confusing since we can now build perf without libelf so there's no need to handle it differently than other libraries. Signed-off-by: Namhyung Kim --- tools/perf/Makefile.perf | 2 --
