arm64: kdump: add VMCOREINFO's for user-space tools
In addition to common VMCOREINFO's defined in crash_save_vmcoreinfo_init(), we need to know, for crash utility, - kimage_voffset - PHYS_OFFSET to examine the contents of a dump file (/proc/vmcore) correctly due to the introduction of KASLR (CONFIG_RANDOMIZE_BASE) in v4.6. - VA_BITS is also required for makedumpfile command. arch_crash_save_vmcoreinfo() appends them to the dump file. More VMCOREINFO's may be added later. Signed-off-by:AKASHI Takahiro <takahiro.akashi@linaro.org> Reviewed-by:
