From 52f993b8e89487ec9ee15a7fb4979e0f09a45b27 Mon Sep 17 00:00:00 2001 From: Yunhong Jiang Date: Wed, 8 Mar 2017 23:13:28 -0800 Subject: Upgrade to 4.4.50-rt62 The current kernel is based on rt kernel v4.4.6-rt14. We will upgrade it to 4.4.50-rt62. The command to achieve it is: a) Clone a git repo from git://git.kernel.org/pub/scm/linux/kernel/git/rt/linux-stable-rt.git b) Get the diff between this two changesets: git diff 640eca2901f3435e616157b11379d3223a44b391 705619beeea1b0b48219a683fd1a901a86fdaf5e where the two commits are: [yjiang5@jnakajim-build linux-stable-rt]$ git show --oneline --name-only 640eca2901f3435e616157b11379d3223a44b391 640eca2901f3 v4.4.6-rt14 localversion-rt [yjiang5@jnakajim-build linux-stable-rt]$ git show --oneline --name-only 705619beeea1b0b48219a683fd1a901a86fdaf5e 705619beeea1 Linux 4.4.50-rt62 localversion-rt c) One patch has been backported thus revert the patch before applying. filterdiff -p1 -x scripts/package/Makefile ~/tmp/v4.4.6-rt14-4.4.50-rt62.diff |patch -p1 --dry-run Upstream status: backport Change-Id: I244d57a32f6066e5a5b9915f9fbf99e7bbca6e01 Signed-off-by: Yunhong Jiang --- kernel/arch/arm/include/asm/cputype.h | 3 +++ kernel/arch/arm/include/asm/dma-mapping.h | 2 +- kernel/arch/arm/include/asm/floppy.h | 2 +- kernel/arch/arm/include/asm/pgtable-2level.h | 1 + kernel/arch/arm/include/asm/pgtable-3level.h | 5 +++-- kernel/arch/arm/include/asm/pgtable.h | 1 - 6 files changed, 9 insertions(+), 5 deletions(-) (limited to 'kernel/arch/arm/include') diff --git a/kernel/arch/arm/include/asm/cputype.h b/kernel/arch/arm/include/asm/cputype.h index 85e374f87..e9d04f475 100644 --- a/kernel/arch/arm/include/asm/cputype.h +++ b/kernel/arch/arm/include/asm/cputype.h @@ -81,6 +81,9 @@ #define ARM_CPU_XSCALE_ARCH_V2 0x4000 #define ARM_CPU_XSCALE_ARCH_V3 0x6000 +/* Qualcomm implemented cores */ +#define ARM_CPU_PART_SCORPION 0x510002d0 + extern unsigned int processor_id; #ifdef CONFIG_CPU_CP15 diff --git a/kernel/arch/arm/include/asm/dma-mapping.h b/kernel/arch/arm/include/asm/dma-mapping.h index ccb3aa646..b91a2d17a 100644 --- a/kernel/arch/arm/include/asm/dma-mapping.h +++ b/kernel/arch/arm/include/asm/dma-mapping.h @@ -119,7 +119,7 @@ static inline dma_addr_t virt_to_dma(struct device *dev, void *addr) /* The ARM override for dma_max_pfn() */ static inline unsigned long dma_max_pfn(struct device *dev) { - return PHYS_PFN_OFFSET + dma_to_pfn(dev, *dev->dma_mask); + return dma_to_pfn(dev, *dev->dma_mask); } #define dma_max_pfn(dev) dma_max_pfn(dev) diff --git a/kernel/arch/arm/include/asm/floppy.h b/kernel/arch/arm/include/asm/floppy.h index f4882553f..85a34cc83 100644 --- a/kernel/arch/arm/include/asm/floppy.h +++ b/kernel/arch/arm/include/asm/floppy.h @@ -17,7 +17,7 @@ #define fd_outb(val,port) \ do { \ - if ((port) == FD_DOR) \ + if ((port) == (u32)FD_DOR) \ fd_setdor((val)); \ else \ outb((val),(port)); \ diff --git a/kernel/arch/arm/include/asm/pgtable-2level.h b/kernel/arch/arm/include/asm/pgtable-2level.h index aeddd28b3..92fd2c8a9 100644 --- a/kernel/arch/arm/include/asm/pgtable-2level.h +++ b/kernel/arch/arm/include/asm/pgtable-2level.h @@ -193,6 +193,7 @@ static inline pmd_t *pmd_offset(pud_t *pud, unsigned long addr) #define pmd_large(pmd) (pmd_val(pmd) & 2) #define pmd_bad(pmd) (pmd_val(pmd) & 2) +#define pmd_present(pmd) (pmd_val(pmd)) #define copy_pmd(pmdpd,pmdps) \ do { \ diff --git a/kernel/arch/arm/include/asm/pgtable-3level.h b/kernel/arch/arm/include/asm/pgtable-3level.h index a745a2a53..fd929b5de 100644 --- a/kernel/arch/arm/include/asm/pgtable-3level.h +++ b/kernel/arch/arm/include/asm/pgtable-3level.h @@ -212,6 +212,7 @@ static inline pmd_t *pmd_offset(pud_t *pud, unsigned long addr) : !!(pmd_val(pmd) & (val))) #define pmd_isclear(pmd, val) (!(pmd_val(pmd) & (val))) +#define pmd_present(pmd) (pmd_isset((pmd), L_PMD_SECT_VALID)) #define pmd_young(pmd) (pmd_isset((pmd), PMD_SECT_AF)) #define pte_special(pte) (pte_isset((pte), L_PTE_SPECIAL)) static inline pte_t pte_mkspecial(pte_t pte) @@ -257,10 +258,10 @@ PMD_BIT_FUNC(mkyoung, |= PMD_SECT_AF); #define pfn_pmd(pfn,prot) (__pmd(((phys_addr_t)(pfn) << PAGE_SHIFT) | pgprot_val(prot))) #define mk_pmd(page,prot) pfn_pmd(page_to_pfn(page),prot) -/* represent a notpresent pmd by zero, this is used by pmdp_invalidate */ +/* represent a notpresent pmd by faulting entry, this is used by pmdp_invalidate */ static inline pmd_t pmd_mknotpresent(pmd_t pmd) { - return __pmd(0); + return __pmd(pmd_val(pmd) & ~L_PMD_SECT_VALID); } static inline pmd_t pmd_modify(pmd_t pmd, pgprot_t newprot) diff --git a/kernel/arch/arm/include/asm/pgtable.h b/kernel/arch/arm/include/asm/pgtable.h index 348caabb7..d62204060 100644 --- a/kernel/arch/arm/include/asm/pgtable.h +++ b/kernel/arch/arm/include/asm/pgtable.h @@ -182,7 +182,6 @@ extern pgd_t swapper_pg_dir[PTRS_PER_PGD]; #define pgd_offset_k(addr) pgd_offset(&init_mm, addr) #define pmd_none(pmd) (!pmd_val(pmd)) -#define pmd_present(pmd) (pmd_val(pmd)) static inline pte_t *pmd_page_vaddr(pmd_t pmd) { -- cgit 1.2.3-korg
