Subject: [ 13/65] ARM: 7478/1: errata: extend workaround for erratum #720789
Date: Mon, 13 Aug 2012 15:13:57 -0700 [thread overview]
Message-ID: <20120813221416.131732811@linuxfoundation.org> (raw)
In-Reply-To: <20120813221414.965154048@linuxfoundation.org>
From: Greg KH <gregkh@linuxfoundation.org>
3.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Will Deacon <will.deacon@arm.com>
commit 5a783cbc48367cfc7b65afc75430953dfe60098f upstream.
Commit cdf357f1 ("ARM: 6299/1: errata: TLBIASIDIS and TLBIMVAIS
operations can broadcast a faulty ASID") replaced by-ASID TLB flushing
operations with all-ASID variants to workaround A9 erratum #720789.
This patch extends the workaround to include the tlb_range operations,
which were overlooked by the original patch.
