2022-03-18kgdbts: fix return value of __setup handlerRandy Dunlap1-2/+2
__setup() handlers should return 1 to indicate that the boot option has been handled. A return of 0 causes the boot option/value to be listed as an Unknown kernel parameter and added to init's (limited) environment strings. So return 1 from kgdbts_option_setup(). Unknown kernel command line parameters "BOOT_IMAGE=/boot/bzImage-517rc7 kgdboc=kbd kgdbts=", will be passed to user space.

2022-03-18bus: mhi: Fix MHI DMA structure endiannessPaul Davey5-103/+104
The MHI driver does not work on big endian architectures. The controller never transitions into mission mode. This appears to be due to the modem device expecting the various contexts and transfer rings to have fields in little endian order in memory, but the driver constructs them in native endianness. Fix MHI event, channel and command contexts and TRE handling macros to use explicit conversion to little endian. Mark fields in relevant structures as little endian to document this requirement.

2022-03-18bus: mhi: Fix pm_state conversion to stringPaul Davey2-5/+7
On big endian architectures the mhi debugfs files which report pm state give "Invalid State" for all states. This is caused by using find_last_bit which takes an unsigned long* while the state is passed in as an enum mhi_pm_state which will be of int size. Fix by using __fls to pass the value of state instead of find_last_bit. Also the current API expects "mhi_pm_state" enumerator as the function argument but the function only works with bitmasks.

2022-03-18parport_pc: Also enable driver for PCI systemsMaciej W. Rozycki6-2/+7
Nowadays PC-style parallel ports come in the form of PCI and PCIe option cards and there are some combined parallel/serial option cards as well that we handle in the parport subsystem. There is nothing in particular that would prevent them from being used in any system equipped with PCI or PCIe connectivity, except that we do not permit the PARPORT_PC config option to be selected for platforms for which ARCH_MIGHT_HAVE_PC_PARPORT has not been set for. The only PCI platforms that actually can't make use of PC-style parallel port hardware are those newer PCIe systems that have no support for I/O cycles in the host bridge, required by such parallel ports. Notably, this includes the s390 arch, which has port I/O accessors that cause compilation warnings (promoted to errors with `-Werror'), and there are other cases such as the POWER9 PHB4 device, though this one has variable port I/O accessors that depend on the particular system. Also it is not clear whether the serial port side of devices enabled by PARPORT_SERIAL uses port I/O or MMIO. Finally Super I/O solutions are always either ISA or platform devices. Make the PARPORT_PC option selectable also for PCI systems then, except for the s390 arch, however limit the availability of PARPORT_PC_SUPERIO to platforms that enable ARCH_MIGHT_HAVE_PC_PARPORT. Update platforms accordingly for the required <asm/parport.h> header. Acked-by: Sudip Mukherjee <[email protected]> Signed-off-by: Maciej W.

2022-03-18pps: generators: pps_gen_parport: Switch to use module_parport_driver()Andy Shevchenko1-35/+7
Switch to use module_parport_driver() to reduce boilerplate code. Note, it doesn't matter when we check the module parameter. If it was writable we even would have more flexibility of changing it at runtime (when built-in the kernel) after this patch.

2022-03-18platform: goldfish: pipe: Use platform_get_irq() to get the interruptLad Prabhakar1-5/+3
platform_get_resource(pdev, IORESOURCE_IRQ, ..) relies on static allocation of IRQ resources in DT core code, this causes an issue when using hierarchical interrupt domains using "interrupts" property in the node as this bypasses the hierarchical setup and messes up the irq chaining. In preparation for removal of static setup of IRQ resource from DT core code use platform_get_irq().

acrn_vm_ram_map can't pin the user pages with VM_PFNMAP flag by calling get_user_pages_fast(), the PA(physical pages) may be mapped by kernel driver and set PFNMAP flag.

2022-03-18mei: avoid iterator usage outside of list_for_each_entryAlexander Usyskin1-20/+15
Usage of the iterator outside of the list_for_each_entry is considered harmful. https://lkml.org/lkml/2022/2/17/1032 Do not reference the loop variable outside of the loop, by rearranging the orders of execution. Instead of performing search loop and checking outside the loop if the end of the list was hit and no matching element was found, the execution is performed inside the loop upon a successful match followed by a goto statement to the next step, therefore no condition has to be performed after the loop has ended.
