msi.c is a maze of randomly sorted functions which makes the code unreadable. As a first step split the driver visible API and the internal implementation which also allows proper API documentation via one file. Create drivers/pci/msi/api.c to group all exported device-driver PCI/MSI APIs in one C file. Begin by moving pci_disable_msi() there and add kernel-doc for the function as appropriate. Suggested-by:

The upcoming support for per device MSI interrupt domains needs to share some of the inline helpers with the MSI implementation. Move them to the header file. Signed-off-by:

Adjust to reality and remove another layer of pointless Kconfig indirection. CONFIG_GENERIC_MSI_IRQ is good enough to serve all purposes. Signed-off-by:

Thomas Gleixner authored
What a zoo: PCI_MSI select GENERIC_MSI_IRQ PCI_MSI_IRQ_DOMAIN def_bool y depends on PCI_MSI select GENERIC_MSI_IRQ_DOMAIN Ergo PCI_MSI enables PCI_MSI_IRQ_DOMAIN which in turn selects GENERIC_MSI_IRQ_DOMAIN. So all the dependencies on PCI_MSI_IRQ_DOMAIN are just an indirection to PCI_MSI. Match the reality and just admit that PCI_MSI requires GENERIC_MSI_IRQ_DOMAIN. Signed-off-by: -

Add a bus token member to struct msi_domain_info and let msi_create_irq_domain() set the bus token. That allows to remove the bus token updates at the call sites. Suggested-by:

Use the new msi_post_free() callback which is invoked after the interrupts have been freed to tell the hypervisor about the shutdown. This allows to remove the exposure of __msi_domain_free_irqs(). Signed-off-by:

Thomas Gleixner authored
To prepare for removing the exposure of __msi_domain_free_irqs() provide a post_free() callback in the MSI domain ops which can be used to solve the problem of the only user of __msi_domain_free_irqs() in arch/powerpc. Signed-off-by:

There are no associated MSI descriptors in the requested range when the MSI descriptor allocation fails. Use MSI_DESC_ALL as the filter which prepares the next step to get rid of the filter for freeing. Signed-off-by:

clocksource/hyperv_timer.h is included into the VDSO build. It includes asm/mshyperv.h which in turn includes the world and some more. This worked so far by chance, but any subtle change in the include chain results in a build breakage because VDSO builds are building user space libraries. Include asm/hyperv-tlfs.h instead which contains everything what the VDSO build needs except the hv_get_raw_timer() define. Move this define into a separate header file, which contains the prerequisites (msr.h) and is included by clocksource/hyperv_timer.h. Fixup drivers/hv/vmbus_drv.c which relies on the indirect include of asm/mshyperv.h. With that the VDSO build only pulls in the minimum requirements. Signed-off-by:

Pull EFI fixes from Ard Biesheuvel: - Force the use of SetVirtualAddressMap() on Ampera Altra arm64 machines, which crash in SetTime() if no virtual remapping is used This is the first time we've added an SMBIOS based quirk on arm64, but fortunately, we can just call a EFI protocol to grab the type #1 SMBIOS record when running in the stub, so we don't need all the machinery we have in the kernel proper to parse SMBIOS data. - Drop a spurious warning on misaligned runtime regions when using 16k or 64k pages on arm64 * tag 'efi-fixes-for-v6.1-3' of git://git.kernel.org/pub/scm/linux/kernel/git/efi/efi: arm64: efi: Fix handling of misaligned runtime regions and drop warning arm64: efi: Force the use of SetVirtualAddressMap() on Altra machines

Pull additional sound fix from Takashi Iwai: "A regression fix for the latest memalloc helper change" * tag 'sound-fix-6.1-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound: ALSA: memalloc: Try dma_alloc_noncontiguous() at first
-
Takashi Iwai authored
The latest fix for the non-contiguous memalloc helper changed the allocation method for a non-IOMMU system to use only the fallback allocator. This should have worked, but it caused a problem sometimes when too many non-contiguous pages are allocated that can't be treated by HD-audio controller. As a quirk workaround, go back to the original strategy: use dma_alloc_noncontiguous() at first, and apply the fallback only when it fails, but only for non-IOMMU case. We'll need a better fix in the fallback code as well, but this workaround should paper over most cases. Fixes: 9736a325 ("ALSA: memalloc: Don't fall back for SG-buffer with IOMMU") Reported-by:

This bug went unnoticed for a long time as commands issued to a drive in error state are aborted immediately and retried by the scsi layer, hiding the useless abort-and-retry sequence" * tag 'ata-6.1-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/dlemoal/libata: ata: libata-core: do not issue non-internal commands once EH is pending ata: libata-transport: fix error handling in ata_tdev_add() ata: libata-transport: fix error handling in ata_tlink_add() ata: libata-transport: fix error handling in ata_tport_add() ata: libata-transport: fix double ata_host_put() in ata_tport_add() ata: libata-scsi: fix SYNCHRONIZE CACHE (16) command failure -
