[PATCH v2] usb: dwc2: Fix SET/CLEAR_FEATURE and GET_STATUS flows

by Minas Harutyunyan

SET/CLEAR_FEATURE for Remote Wakeup allowance not handled correctly. GET_STATUS handling provided not correct data on DATA Stage. Issue seen when gadget's dr_mode set to "otg" mode and connected to MacOS. Both are fixed and tested using USBCV Ch.9 tests.

[PATCH] MIPS: Use __copy_{to, from}_user() for emulated FP loads/stores

by Paul Burton

Our FPU emulator currently uses __get_user() & __put_user() to perform emulated loads & stores. This is problematic because __get_user() & __put_user() are only suitable for naturally aligned memory accesses, and the address we're accessing is entirely under the control of userland. This allows userland to cause a kernel panic by simply performing an unaligned floating point load or store - the kernel will handle the address error exception by attempting to emulate the instruction, and in the process it may generate another address error exception itself. This time the exception is taken with EPC pointing at the kernels FPU emulation code, and we hit a die_if_kernel() in emulate_load_store_insn(). Fix this up by using __copy_from_user() instead of __get_user() and __copy_to_user() instead of __put_user(). These replacements will handle arbitrary alignment without problems.

[PATCH] cpu/SMT: fix x86 link error without CONFIG_SYSFS

by Arnd Bergmann

When CONFIG_SYSFS is disabled, but CONFIG_HOTPLUG_SMT is enabled, the kernel fails to link: arch/x86/power/cpu.o: In function `hibernate_resume_nonboot_cpu_disable': (.text+0x38d): undefined reference to `cpuhp_smt_enable' arch/x86/power/hibernate.o: In function `arch_resume_nosmt': hibernate.c:(.text+0x291): undefined reference to `cpuhp_smt_enable' hibernate.c:(.text+0x29c): undefined reference to `cpuhp_smt_disable' Move the exported functions out of the #ifdef section into its own with the correct conditions. The patch that caused this is marked for stable backports, so this one may need to be backported as well.

[PATCH RESEND v2] ARM: dma-api: fix max_pfn off-by-one error in __dma_supported()

by Chen-Yu Tsai

From: Chen-Yu Tsai <wens(a)csie.org> max_pfn, as set in arch/arm/mm/init.c: static void __init find_limits(unsigned long *min, unsigned long *max_low, unsigned long *max_high) { *max_low = PFN_DOWN(memblock_get_current_limit()); *min = PFN_UP(memblock_start_of_DRAM()); *max_high = PFN_DOWN(memblock_end_of_DRAM()); } with memblock_end_of_DRAM() pointing to the next byte after DRAM. As such, max_pfn points to the PFN after the end of DRAM. Thus when using max_pfn to check DMA masks, we should subtract one when checking DMA ranges against it. Commit 8bf1268f48ad ("ARM: dma-api: fix off-by-one error in __dma_supported()") fixed the same issue, but missed this spot. This issue was found while working on the sun4i-csi v4l2 driver on the Allwinner R40 SoC. On Allwinner SoCs, DRAM is offset at 0x40000000, and we are starting to use of_dma_configure() with the "dma-ranges" property in the device tree to have the DMA API handle the offset. In this particular instance, dma-ranges was set to the same range as the actual available (2 GiB) DRAM. The following error appeared when the driver attempted to allocate a buffer: sun4i-csi 1c09000.csi: Coherent DMA mask 0x7fffffff (pfn 0x40000-0xc0000) covers a smaller range of system memory than the DMA zone pfn 0x0-0xc0001 sun4i-csi 1c09000.csi: dma_alloc_coherent of size 307200 failed Fixing the off-by-one error makes things work. Fixes: 11a5aa32562e ("ARM: dma-mapping: check DMA mask against available memory") Fixes: 9f28cde0bc64 ("ARM: another fix for the DMA mapping checks") Fixes: ab746573c405 ("ARM: dma-mapping: allow larger DMA mask than supported") Cc: <stable(a)vger.kernel.org> Signed-off-by: Chen-Yu Tsai <wens(a)csie.org> --- It's been close to two weeks since I sent this. I wasn't sure if I reached the right maintainers, so I'm resending this to more people.
