Subject: [PATCH 6/7] [PATCH v3 6/7] makedumpfile: Discard process_dump_load
|
|
|
766e0d |
|
|
|
766e0d |
Kernel commit 464920104bf7 (/proc/kcore: update physical address for
|
|
|
766e0d |
kcore ram and text) provides physical address of direct mapping kcore
|
|
|
766e0d |
program segments. So no need to calculate it specifically now. And the
|
|
|
766e0d |
old code is not correct since it calls vaddr_to_paddr() which has not
|
|
|
766e0d |
been ready at that time.
