The kernel can change spinlock behavior when running as a guest. But
this guest-friendly behavior causes performance problems on bare metal.
So there's a 'virt_spin_lock_key' static key to switch between the two

PARAVIRT option and pv ipi is added on guest kernel side, function
pv_ipi_init() is to add ipi sending and ipi receiving hooks. This function
firstly checks whether system runs on VM mode. If kernel runs on VM mode,
it will call function kvm_para_available() to detect current hypervirsor
type. Now
On LoongArch system, ipi hw uses iocsr registers, there is one iocsr
register access on ipi sending, and two iocsr access on ipi receiving
which is ipi interrupt handler. On VM mode all iocsr accessing will
cause VM to trap into hypervisor. So with one ipi hw notification
there will be three times
On physical machine, ipi HW uses IOCSR registers, however there is trap
into hypervisor when vcpu accesses IOCSR registers if system is in VM
mode. SWI is a interrupt mechanism like SGI on ARM, software can send
interrupt to CPU, only that on LoongArch SWI can only be sent to local CPU
now. So SWI
It is code refine about ipi handling on LoongArch platform, there are
three modifications.
1. Add generic function get_percpu_irq(), replacing some percpu irq
functions such as get_ipi_irq()/get_pmc_irq()/get_timer_irq() with

v2 is already in the tree, if the change is important you need to send
an incremental fix.

It was observed in the wild that pairs of consecutive packets would leave
the IPVS with the same wrong checksum, and the issue only went away when
disabling GSO.
IPVS needs to avoid computing the SCTP checksum when using GSO.

from the current K3 R5 and DSP drivers have been dropped. I'd like
to do that re-factor *after* getting this driver in shape, that way
we have 3 similar drivers to factor out from vs trying to make those
changes in parallel with the series adding M4 support.
Anyway, details on our M4F s
Neat! :) I had a look at mostly the "high level" part (fprobe and
arm64 specific bits) and this seems to be in a good state to me.
Thanks for all that work, that is quite a refactoring :)

Active uprobes are stored in an RB tree and accesses to this tree are
dominated by read operations. Currently these accesses are serialized by
a spinlock but this leads to enormous contention when large numbers of
threads are executing active probes.
