krnowak: Backport to 5.15 - this patch adds the hv_msi_get_int_vector

function for x64, so drop the same function that was brought in by

another patch backported to 5.15 from master. Similar thing goes for

the hv_msi_prepare function, but this time the function brought under

the CONFIG_X86 is amended to match the fixed variant that was already

Subject: [PATCH 6/7] PCI: hv: Avoid the retarget interrupt hypercall in
|

irq_unmask() on ARM64
|

MIME-Version: 1.0
|
||||
Content-Type: text/plain; charset=UTF-8

|
||||
|
||||
On ARM64 Hyper-V guests, SPIs are used for the interrupts of virtual PCI
|
||||
devices, and SPIs can be managed directly via GICD registers. Therefore
|
||||
the retarget interrupt hypercall is not needed on ARM64.
|
||||
|
||||
An arch-specific interface hv_arch_irq_unmask() is introduced to handle
|
||||
the architecture level differences on this. For x86, the behavior
|
||||
remains unchanged, while for ARM64 no hypercall is invoked when
|
||||
unmasking an irq for virtual PCI devices.

Subject: [PATCH 7/7] PCI: hv: Remove unused hv_set_msi_entry_from_desc()

Fix the following build error:
|
||||
|
||||
drivers/pci/controller/pci-hyperv.c:769:13: error: ‘hv_set_msi_entry_from_desc’ defined but not used [-Werror=unused-function]
|
||||
769 | static void hv_set_msi_entry_from_desc(union hv_msi_entry *msi_entry,
|
||||
|
||||
The arm64 implementation of hv_set_msi_entry_from_desc() is not used after
|
||||
d06957d7a692 ("PCI: hv: Avoid the retarget interrupt hypercall in
|
||||
irq_unmask() on ARM64"), so remove it.
|
||||
