Subject: [Makedumpfile PATCH V2 0/4] x86_64: Fix page_offset for randomized base enabled
Date: Mon, 31 Oct 2016 13:47:33 +0530 [thread overview]
Message-ID: <cover.1477901442.git.panand@redhat.com> (raw)
Patch 1/4 fixes page_offset calculation, so that it is correctly calculated
on KASLR enabled kernel as well.
Patch 2/4 simplifies VA to PA translation. New code has been benchmarked
against old code on a 4T system.
Patch 3/4 and 4/4 is removal of (now) unnecessary code.
I think, we should find a way to kill find_vememmap() as well, so that
VMEMMAP_START can be removed. I have very limited idea about x86, so unable
to do that as of now.
Changes since V1:
* A bug in patch 1/4 fixed
* Patch log of 2/4 improved to include more number of trials
Pratyush Anand (4):
x86_64: Calculate page_offset from pt_load
x86_64: translate all VA to PA using page table values
x86_64: kill is_vmalloc_addr_x86_64()
x86_64: kill some unused initialization
