This series of patches are tested on 4.9 kernel with Cortex-A75 based SoC. These patches can also go into '-stable' branch (if accepted) for 4.6 onwards. >From V7->V8: - Properly fixed compilation issue in x86 file >From V6->V7: - Fixed compilation issue in x86 case - V6 patches were not properly enumarated >From V5->V6: - Use __flush_tlb_kernel_pgtable() for both PUD and PMD. Remove "bool tlb_inv" based variance as it is not need now - Re-naming for consistency >From V4->V5: - Add new API __flush_tlb_kernel_pgtable(unsigned long addr) for kernel addresses >From V3->V4: - Add header for 'addr' in x86 implementation - Re-order pmd/pud clear and table free - Avoid redundant TLB invalidatation in one perticular case >From V2->V3: - Use the exisiting page table free interface to do arm64 specific things >From V1->V2: - Rebased my patches on top of "[PATCH v2 1/2] mm/vmalloc: Add interfaces to free unmapped page table" - Honored BBM for ARM64 Chintan Pandya (4): ioremap: Update pgtable free interfaces with addr arm64: tlbflush: Introduce __flush_tlb_kernel_pgtable arm64: Implement page table free interfaces Revert "arm64: Enforce BBM for huge IO/VMAP mappings" arch/arm64/include/asm/tlbflush.h | 6 ++++++ arch/arm64/mm/mmu.c | 37 +++++++++++++++++++++++++------------ arch/x86/mm/pgtable.c | 8 +++++--- include/asm-generic/pgtable.h | 8 ++++---- lib/ioremap.c | 4 ++-- 5 files changed, 42 insertions(+), 21 deletions(-) -- Qualcomm India Private Limited, on behalf of Qualcomm Innovation Center, Inc., is a member of Code Aurora Forum, a Linux Foundation Collaborative Project From mboxrd@z Thu Jan 1 00:00:00 1970 Return-Path: Received: from smtp.codeaurora.org ([198.145.29.96]:40656 "EHLO smtp.codeaurora.org" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with ESMTP id S1754583AbeDCIBC (ORCPT ); Tue, 3 Apr 2018 04:01:02 -0400 From: Chintan Pandya Subject: [PATCH v8 0/4] Fix issues with huge mapping in ioremap for ARM64 Date: Tue, 3 Apr 2018 13:30:42 +0530 Message-ID: <1522742446-5084-1-git-send-email-cpandya@codeaurora.org> Sender: linux-arch-owner@vger.kernel.org List-ID: To: catalin.marinas@arm.com, will.deacon@arm.com, mark.rutland@arm.com, toshi.kani@hpe.com Cc: arnd@arndb.de, ard.biesheuvel@linaro.org, marc.zyngier@arm.com, james.morse@arm.com, kristina.martsenko@arm.com, takahiro.akashi@linaro.org, gregkh@linuxfoundation.org, tglx@linutronix.de, linux-arm-kernel@lists.infradead.org, linux-kernel@vger.kernel.org, linux-arch@vger.kernel.org, akpm@linux-foundation.org, Chintan Pandya Message-ID: <20180403080042.rV36Dyng-x63tGKdnwMdm-nnRcRq_e1o4aGrZcyXTyo@z> This series of patches are follow up work (and depends on) Toshi Kani 's patches "fix memory leak/ panic in ioremap huge pages".
