From mboxrd@z Thu Jan 1 00:00:00 1970 From: mark.rutland@arm.com (Mark Rutland) Date: Mon, 12 Jan 2015 16:45:13 +0000 Subject: [PATCHv2 0/7] arm64/kvm: common ESR_ELx definitions and decoding Message-ID: <1421081120-7694-1-git-send-email-mark.rutland@arm.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org Currently we have two sets of macros used for ESR_ELx handling, one used by core arm64 code and the other used by KVM. These differ slightly in naming convention and style of definition. This patch series introduces and migrates all users to a common set of macros for ESR_ELx handling, preventing further drift. Additionally this series adds exception class decoding when reporting exceptions, saving deveopers from having to perform tedious mental arithmetic to figure out what the likely cause of an unexpected exception was. Since v1 [1]: * Reorder patches to maintain KVM bisectability. * Fix bad definitions (ESR_ELx_SAS and ESR_ELx_FSC_PERM). * Introcuce ESR_ELx_SAS_SHIFT and undo bad rework of kvm_vcpu_dabt_get_as. * Make "Unallocated EC" comments consistent in ESR_ELx_EC_* definition list. Many thanks to those who have reviewed this so far. Mark.
