Subject: [PATCH 0/5] ARM: Cache maintenance changes
Date: Tue, 20 Jul 2010 18:12:01 +0100 [thread overview]
Message-ID: <20100720171201.19582.85920.stgit@e102109-lin.cambridge.arm.com> (raw)
Hi,
These patches have been posted on the linux-arm-kernel mailing list in
the past but I'm cc'ing linux-arch this time (following Fujita's
suggestion).
The main feature is the second patch - changing the meaning of PG_arch_1
from 'dirty' to 'clean' so that we do cache flushing even for PIO
drivers that do not call flush_dcache_page() (similarly to IA-64 and
PowerPC). There is some clean-up as well to avoid excessive flushing.
Catalin Marinas (5):
ARM: Allow lazy cache flushing via PG_arch_1 for highmem pages
ARM: Assume new page cache pages have dirty D-cache
ARM: Introduce __sync_icache_dcache() for VIPT caches
ARM: Use lazy cache flushing on ARMv7 SMP systems
ARM: Remove superfluous flush_kernel_dcache_page()
