2021-07-21MIPS: Malta: Do not byte-swap accesses to the CBUS UARTMaciej W. Rozycki1-1/+2
Correct big-endian accesses to the CBUS UART, a Malta on-board discrete TI16C550C part wired directly to the system controller's device bus, and do not use byte swapping with the 32-bit accesses to the device. The CBUS is used for devices such as the boot flash memory needed early on in system bootstrap even before PCI has been initialised. Therefore it uses the system controller's device bus, which follows the endianness set with the CPU, which means no byte-swapping is ever required for data accesses to CBUS, unlike with PCI. The CBUS UART uses the UPIO_MEM32 access method, that is the `readl' and `writel' MMIO accessors, which on the MIPS platform imply byte-swapping with PCI systems. Consequently the wrong byte lane is accessed with the big-endian configuration and the UART is not correctly accessed. As it happens the UPIO_MEM32BE access method makes use of the `ioread32' and `iowrite32' MMIO accessors, which still use `readl' and `writel' respectively, however they byte-swap data passed, effectively cancelling swapping done with the accessors themselves and making it suitable for the CBUS UART. Make the CBUS UART switch between UPIO_MEM32 and UPIO_MEM32BE then, based on the endianness selected. With this change in place the device is correctly recognised with big-endian Malta at boot, along with the Super I/O devices behind PCI: Serial: 8250/16550 driver, 5 ports, IRQ sharing enabled printk: console [ttyS0] disabled serial8250.0: ttyS0 at I/O 0x3f8 (irq = 4, base_baud = 115200) is a 16550A printk: console [ttyS0] enabled printk: bootconsole [uart8250] disabled serial8250.0: ttyS1 at I/O 0x2f8 (irq = 3, base_baud = 115200) is a 16550A serial8250.0: ttyS2 at MMIO 0x1f000900 (irq = 20, base_baud = 230400) is a 16550A Fixes: e7c4782f92fc ("[MIPS] Put an end to <asm/serial.h>'s long and annyoing existence") Cc: stable@vger.kernel.org # v2.6.23+ Reviewed-by: Philippe Mathieu-Daudé <f4bug@amsat.org> Signed-off-by: Maciej W.

2021-07-21Revert "mm/pgtable: add stubs for {pmd/pub}_{set/clear}_huge"Jonathan Marek3-31/+33
This reverts commit c742199a014de23ee92055c2473d91fe5561ffdf. c742199a014d ("mm/pgtable: add stubs for {pmd/pub}_{set/clear}_huge") breaks arm64 in at least two ways for configurations where PUD or PMD folding occur: 1. We no longer install huge-vmap mappings and silently fall back to page-granular entries, despite being able to install block entries at what is effectively the PGD level. 2. If the linear map is backed with block mappings, these will now silently fail to be created in alloc_init_pud(), causing a panic early during boot. The pgtable selftests caught this, although a fix has not been forthcoming and Christophe is AWOL at the moment, so just revert the change for now to get a working -rc3 on which we can queue patches for 5.15. A simple revert breaks the build for 32-bit PowerPC 8xx machines, which rely on the default function definitions when the corresponding page-table levels are folded, since commit a6a8f7c4aa7e ("powerpc/8xx: add support for huge pages on VMAP and VMALLOC"), eg: powerpc64-linux-ld: mm/vmalloc.o: in function `vunmap_pud_range': linux/mm/vmalloc.c:362: undefined reference to `pud_clear_huge' To avoid that, add stubs for pud_clear_huge() and pmd_clear_huge() in arch/powerpc/mm/nohash/8xx.c as suggested by Christophe.

2021-07-21drivers/firmware: consolidate EFI framebuffer setup for all archesJavier Martinez Canillas3-12/+3
The register_gop_device() function registers an "efi-framebuffer" platform device to match against the efifb driver, to have an early framebuffer for EFI platforms. But there is already support to do exactly the same by the Generic System Framebuffers (sysfb) driver. This used to be only for X86 but it has been moved to drivers/firmware and could be reused by other architectures. Also, besides supporting registering an "efi-framebuffer", this driver can register a "simple-framebuffer" allowing to use the siple{fb,drm} drivers on non-X86 EFI platforms. For example, on aarch64 these drivers can only be used with DT and doesn't have code to register a "simple-frambuffer" platform device when booting with EFI. For these reasons, let's remove the register_gop_device() duplicated code and instead move the platform specific logic that's there to sysfb driver.

2021-07-21drivers/firmware: move x86 Generic System Framebuffers supportJavier Martinez Canillas6-588/+0
The x86 architecture has generic support to register a system framebuffer platform device. It either registers a "simple-framebuffer" if the config option CONFIG_X86_SYSFB is enabled, or a legacy VGA/VBE/EFI FB device. But the code is generic enough to be reused by other architectures and can be moved out of the arch/x86 directory. This will allow to also support the simple{fb,drm} drivers on non-x86 EFI platforms, such as aarch64 where these drivers are only supported with DT.

2021-07-21bus: Make remove callback return voidUwe Kleine-König9-22/+10
The driver core ignores the return value of this callback because there is only little it can do when a device disappears. This is the final bit of a long lasting cleanup quest where several buses were converted to also return void from their remove callback. Additionally some resource leaks were fixed that were caused by drivers returning an error code in the expectation that the driver won't go away. With struct bus_type::remove returning void it's prevented that newly implemented buses return an ignored error code and so don't anticipate wrong expectations for driver authors.

2021-07-20s390/boot: fix use of expolines in the DMA codeAlexander Egorenkov1-15/+4
The DMA code section of the decompressor must be compiled with expolines if Spectre V2 mitigation has been enabled for the decompressed kernel. This is required because although the decompressor's image contains the DMA code section, it is handed over to the decompressed kernel for use. Because the DMA code is already slow w/o expolines, use expolines always regardless whether the decompressed kernel is using them or not. This simplifies the DMA code by dropping the conditional compilation of expolines.
