[PATCH] ARM: dts: exynos: Fix GPIO polarity for thr GalaxyS3 CM36651 sensor's bus

by Marek Szyprowski

GPIO lines for the CM36651 sensor I2C bus use the normal not the inverted polarity. This bug has been there since adding the CM36651 sensor by commit 85cb4e0bd2294, but went unnoticed because the "i2c-gpio" driver ignored the GPIO polarity specified in the device-tree. The recent conversion of "i2c-gpio" driver to the new, descriptor based GPIO API, automatically made it the DT-specified polarity aware, what broke the CM36651 sensor operation. Fixes: c769eaf7a85d ("ARM: dts: exynos: Split Trats2 DTS in preparation for Midas boards") Fixes: c10d3290cbde ("ARM: dts: Use GPIO constants for flags cells in exynos4412 boards") Fixes: 85cb4e0bd229 ("ARM: dts: add cm36651 light/proximity sensor node for exynos4412-trats2") CC: stable(a)vger.kernel.org # 4.16+ Signed-off-by: Marek Szyprowski <m.szyprowski(a)samsung.com> --- arch/arm/boot/dts/exynos4412-galaxy-s3.dtsi | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/arch/arm/boot/dts/exynos4412-galaxy-s3.dtsi b/arch/arm/boot/dts/exynos4412-galaxy-s3.dtsi index 44f97546dd0a..f910aa924bfb 100644 --- a/arch/arm/boot/dts/exynos4412-galaxy-s3.dtsi +++ b/arch/arm/boot/dts/exynos4412-galaxy-s3.dtsi @@ -68,7 +68,7 @@ i2c_cm36651: i2c-gpio-2 { compatible = "i2c-gpio"; - gpios = <&gpf0 0 GPIO_ACTIVE_LOW>, <&gpf0 1 GPIO_ACTIVE_LOW>; + gpios = <&gpf0 0 GPIO_ACTIVE_HIGH>, <&gpf0 1 GPIO_ACTIVE_HIGH>; i2c-gpio,delay-us = <2>; #address-cells = <1>; #size-cells = <0>; -- 2.17.1

[PATCH] mpt3sas: Fix kernel panic observed on soft HBA unplug

by Sreekanth Reddy

Generic protection fault type kernel panic is observed when user performs soft(ordered) HBA unplug operation while IOs are running on drives connected to HBA. When user performs ordered HBA removal operation then kernel calls PCI device's .remove() call back function where driver is flushing out all the outstanding SCSI IO commands with DID_NO_CONNECT host byte and also un-maps sg buffers allocated for these IO commands. But in the ordered HBA removal case (unlike of real HBA hot unplug) HBA device is still alive and hence HBA hardware is performing the DMA operations to those buffers on the system memory which are already unmapped while flushing out the outstanding SCSI IO commands and this leads to Kernel panic. Fix: Don't flush out the outstanding IOs from .remove() path in case of ordered HBA removal since HBA will be still alive in this case and it can complete the outstanding IOs. Flush out the outstanding IOs only in case physical HBA hot unplug where their won't be any communication with the HBA.

[PATCH v2] mm/sparse: Fix kernel crash with pfn_section_valid check

This was done so that pfn_page() can work correctly with kernel config that disables SPARSEMEM_VMEMMAP. With that config pfn_to_page does __section_mem_map_addr(__sec) + __pfn; where static inline struct page *__section_mem_map_addr(struct mem_section *section) { unsigned long map = section->section_mem_map; map &= SECTION_MAP_MASK; return (struct page *)map; } Now with SPASEMEM_VMEMAP enabled, mem_section->usage->subsection_map is used to check the pfn validity (pfn_valid()). Since section_deactivate release mem_section->usage if a section is fully deactivated, pfn_valid() check after a subsection_deactivate cause a kernel crash. static inline int pfn_valid(unsigned long pfn) { ... return early_section(ms) || pfn_section_valid(ms, pfn); } where static inline int pfn_section_valid(struct mem_section *ms, unsigned long pfn) { int idx = subsection_map_index(pfn); return test_bit(idx, ms->usage->subsection_map); } Avoid this by clearing SECTION_HAS_MEM_MAP when mem_section->usage is freed. For architectures like ppc64 where large pages are used for vmmemap mapping (16MB), a specific vmemmap mapping can cover multiple sections. Hence before a vmemmap mapping page can be freed, the kernel needs to make sure there are no valid sections within that mapping. Clearing the section valid bit before depopulate_section_memap enables this.
