Subject: crash: export paddr_vmcoreinfo_note()
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=43d4cb47f6e854ea9fe868eedf8281f81b5a1252;p=linux.git

crash: export paddr_vmcoreinfo_note()

The following patch is going to use the symbol from the fw_cfg module,
to call the function and write the note location details in the
vmcoreinfo entry, so qemu can produce dumps with the vmcoreinfo note.
