2013-07-03mm: introduce helper function mem_init_print_info() to simplify mem_init()Jiang Liu2-0/+64
Introduce helper function mem_init_print_info() to simplify mem_init() across different architectures, which also unifies the format and information printed. Function mem_init_print_info() calculates memory statistics information without walking each page, so it should be a little faster on some architectures. Also introduce another helper get_num_physpages() to kill the global variable num_physpages.

2013-07-03UML: normalize global variables exported by vmlinux.ldsJiang Liu3-5/+9
Normalize global variables exported by vmlinux.lds to conform usage guidelines from include/asm-generic/sections.h. 1) Use _text to mark the start of the kernel image including the head text, and _stext to mark the start of the .text section. 2) Export mandatory global variables __bss_stop. 3) Adjust __init_begin and __init_end to avoid acrossing .text and .data sections.
