2021-12-13bpf, x64: Replace some stack_size usage with offset variablesJiri Olsa1-14/+28
As suggested by Andrii, adding variables for registers and ip address offsets, which makes the code more clear, rather than abusing single stack_size variable for everything. Also describing the stack layout in the comment. There is no function change.

2021-12-13arm64: dts: qcom: Add device tree for Samsung J5 2015 (samsung-j5)Julian Ribbeck2-0/+210
Samsung J5 2015 is a MSM8916 based Smartphone. It is similar to some of the other MSM8916 devices, especially the Samsung ones. With this patch initial support for the following is added: - eMMC/SD card - Buttons - USB (although no suiting MUIC driver currently) - UART (untested for lack of equipment) - WiFi/Bluetooth (WCNSS) It is worth noting that Samsung J5 with MSM8916 exists in different generations (e.g Samsung J5 2015 and Samsung J5 2016) which each have different models (e.g. samsung-j5nlte, samsung-j5xnlte, etc). This patch is only regarding the 2015 generation, but should work with all of it's models, as far as we could test.

2021-12-13efi: Move efifb_setup_from_dmi() prototype from arch headersJavier Martinez Canillas4-5/+0
Commit 8633ef82f101 ("drivers/firmware: consolidate EFI framebuffer setup for all arches") made the Generic System Framebuffers (sysfb) driver able to be built on non-x86 architectures. But it left the efifb_setup_from_dmi() function prototype declaration in the architecture specific headers. This could lead to the following compiler warning as reported by the kernel test robot: drivers/firmware/efi/sysfb_efi.c:70:6: warning: no previous prototype for function 'efifb_setup_from_dmi' [-Wmissing-prototypes] void efifb_setup_from_dmi(struct screen_info *si, const char *opt) ^ drivers/firmware/efi/sysfb_efi.c:70:1: note: declare 'static' if the function is not intended to be used outside of this translation unit void efifb_setup_from_dmi(struct screen_info *si, const char *opt) Fixes: 8633ef82f101 ("drivers/firmware: consolidate EFI framebuffer setup for all arches") Reported-by: kernel test robot <lkp@intel.com> Cc: <stable@vger.kernel.org> # 5.15.x Signed-off-by: Javier Martinez Canillas <javierm@redhat.com> Acked-by: Thomas Zimmermann <tzimmermann@suse.de> Link: https://lore.kernel.org/r/20211126001333.555514-1-javierm@redhat.com Signed-off-by: Ard Biesheuvel <ardb@kernel.org>

Naming clocks is a good practice.

2021-12-11futex: Fix additional regressionsArnd Bergmann2-4/+4
Naresh reported another architecture that was broken by the same typo that was already fixed for three architectures: mips also refers to the futex_atomic_op_inuser_local() function by the wrong name and runs into a missing closing '}' as well. Going through the source tree the same typo was found in the documentation as well as in the xtensa code, both of which ended up escaping the regression testing so far. In the case of xtensa, it appears that the broken code path is only used when building for platforms that are not supported by the default gcc configuration, so they are impossible to test for with default setups. After going through these more carefully and fixing up the typos, all architectures have been build-tested again to ensure that this is now complete.

2021-12-11arm64: dts: rockchip: Add spi1 pins on Quartz64 ANicolas Frattaroli1-0/+5
The Quartz64 Model A has the SPI pins broken out on its pin header. The actual pins being used though are not the m0 variant, but the m1 variant, which also lacks the cs1 pin. This commit overrides pinctrl-0 accordingly for this board. spi1 is intentionally left disabled, as anyone wishing to add SPI devices needs to edit the dts anyway, and the pins are more useful as GPIOs for the rest of the users.

2021-12-11arm64: dts: rockchip: Add spi nodes on rk356xNicolas Frattaroli1-0/+64
This adds the four spi nodes (spi0, spi1, spi2, spi3) to the rk356x dtsi. These are from the downstream device tree, though I have double-checked that their interrupts and DMA numbers are correct. I have also tested spi1 with an SPI device.

2021-12-11x86/word-at-a-time: Remove .fixup usagePeter Zijlstra1-19/+47
Rewrite load_unaligned_zeropad() to not require .fixup text. This is easiest done using asm-goto-output, where we can stick a C label in the exception table entry. The fallback version isn't nearly so nice but should work.

2021-12-11x86/usercopy: Remove .fixup usagePeter Zijlstra4-28/+22
Typically usercopy does whole word copies followed by a number of byte copies to finish the tail. This means that on exception it needs to compute the remaining length as: words*sizeof(long) + bytes. Create a new extable handler to do just this.
