From: Catalin Marinas <catalin.marinas@arm.com> To: linux-arm-kernel@lists.infradead.org, linux-kernel@vger.kernel.org Subject: [PATCH v2 00/20] ARM: Add support for the Large Physical Address Extensions Date: Fri, 12 Nov 2010 18:00:20 +0000 [thread overview] Message-ID: <1289584840-18097-1-git-send-email-catalin.marinas@arm.com> (raw) Hi, This set of patches adds support for the Large Physical Extensions on the ARM architecture (available with the Cortex-A15 processor). LPAE comes with a 3-level page table format (compared to 2-level for the classic one), allowing up to 40-bit physical address space. The ARM LPAE documentation is available from (free registration needed): http://infocenter.arm.com/help/topic/com.arm.doc.ddi0406b_virtualization_extns/index.html The full set of patches (kernel fixes, LPAE and support for an emulated Versatile Express with Cortex-A15 tile) is available on this branch: git://git.kernel.org/pub/scm/linux/kernel/git/cmarinas/linux-2.6-cm.git arm-lpae Changelog: - Upgraded to latest mainline kernel (2.6.37-rc1) solving several conflicts. - Enable CONFIG_ARCH_DMA_ADDR_T_64BIT for future compatibility with the unified dma_addr_t patch. - PHYS_ADDR_FMT printk format changed to be ANSI C compliant. - Alignment fault now uses SIGBUS instead of SIGILL. - arch/arm/kernel/head.S modified to use SECTION_SHIFT and reduce the amount of #ifdef's. - setup_mm_for_reboot() modified for LPAE. - identity_mapping_add/del() modified for LPAE. - Removed FIRST_USER_PGD_NR definition as the place where it was used have been modified. Any comments are welcome. Thanks.
