From: "Joel Fernandes (Google)" <joel@xxxxxxxxxxxxxxxxx>
This series speeds up mremap(2) syscall by copying page tables at the
PMD level even for non-THP systems. There is concern that the extra
'address' argument that mremap passes to pte_alloc may do something
subtle architecture related in the future that may make the scheme not
work. Also we find that there is no point in passing the 'address' to
pte_alloc since its unused. So this patch therefore removes this
argument tree-wide resulting in a nice negative diff as well. Also
ensuring along the way that the enabled architectures do not do anything
funky with 'address' argument that goes unnoticed by the optimization.
Build and boot tested on x86-64. Build tested on arm64.
The changes were obtained by applying the following Coccinelle script.
(thanks Julia for answering all Coccinelle questions!).
Following fix ups were done manually:
* Removal of address argument from pte_fragment_alloc
* Removal of pte_alloc_one_fast definitions from m68k and microblaze.
// Options: --include-headers --no-includes
// Note: I split the 'identifier fn' line, so if you are manually
// running it, please unsplit it so it runs for you.
