Subject: [PATCH v3 0/4] TLB/I$ flush cleanups and improvements
Date: Sat, 9 Mar 2019 14:52:02 +0000	[thread overview]
Message-ID: <cover.1552142593.git.gary@garyguo.net> (raw)

From: Gary Guo <gary@garyguo.net>

Sorry, I didn't realised that there is a for-next branch and is basing
my changes on top of master/HEAD instead. I've now rebased and fix a new
reference of of local_flush_tlb_page.

This patches does:
1. Move long and expensive functions aways from header files.
2. Fix missing arguments for SBI calls.
3. Performance improvements for TLB flush.

Changes since v2:
 - Replace __setup with early_param
 - Rebase on top of for-next

Changes since v1:
 - Use kernel boot parameters instead of Kconfig
 - Style fixes

Gary Guo (4):
  riscv: move flush_icache_{all,mm} to cacheflush.c
  riscv: move switch_mm to its own file
  riscv: fix sbi_remote_sfence_vma{,_asid}.
  riscv: rewrite tlb flush for performance
