Wei Hu 0010132dbd Hyper-V: vPCI: fix cpu id mis-mapping in vmbus_pcib_map_msi()
The msi address contains apic id. The code in vmbus_pcib_map_msi()
treats it as cpu id, which could cause mis-configuration of msix
IRQs, leading to missing interrupts for SRIOV devices. This happens
when apic id is not the same as cpu id on certain large VM sizes
with multiple numa domains in Azure. Fix this issue by correctly
mapping apic ids to cpu ids.

On vPCI version before 1.4, it only supports up to 64 vcpus
for msi/msix interrupt. This change also adds a check and returns
error if the vcpu_id is greater than 63.

FreeBSD Kernel Source:

This directory contains the source files and build glue that make up the FreeBSD kernel and its modules, including both original and contributed software.

Kernel configuration files are located in the conf/ subdirectory of each architecture. GENERIC is the configuration used in release builds. NOTES contains documentation of all possible entries. LINT is a compile-only configuration used to maximize build coverage and detect regressions.

Documentation:

Source code documentation is maintained in a set of man pages, under section 9. These pages are located in share/man/man9, from the top-level of the src tree. Consult intro(9) for an overview of existing pages.

Some additional high-level documentation of the kernel is maintained in the Architecture Handbook.
