Subject: [PATCH 07/20] mm, arch: Remove tlb_flush()
Date: Wed, 27 Jun 2012 23:15:47 +0200 [thread overview]
Message-ID: <20120627212831.062889833@chello.nl> (raw)
In-Reply-To: 20120627211540.459910855@chello.nl
[-- Attachment #1: generic_tlb_flush.patch --]
[-- Type: text/plain, Size: 11831 bytes --]
Since all asm-generic/tlb.h users their tlb_flush() implementation is
now either a nop or flush_tlb_mm(), remove it and make the generic
code use flush_tlb_mm() directly.
