X86/Hyper-V: Add flush HvFlushGuestPhysicalAddressSpace hypercall support Hyper-V supports a pv hypercall HvFlushGuestPhysicalAddressSpace to flush nested VM address space mapping in l1 hypervisor and it's to reduce overhead of flushing ept tlb among vcpus. This patch is to implement it. Signed-off-by: Lan Tianyu <Tianyu.Lan@microsoft.com> Acked-by: K. Y.

x86/Hyper-V/hv_apic: Build the Hyper-V APIC conditionally The Hyper-V APIC code is built when CONFIG_HYPERV is enabled but the actual code in that file is guarded with CONFIG_X86_64. There is no point in doing this. Neither is there a point in having the CONFIG_HYPERV guard in there because the containing directory is not built when CONFIG_HYPERV=n. Further for the hv_init_apic() function a stub is provided only for CONFIG_HYPERV=n, which is pointless as the callsite is not compiled at all. But for X86_32 the stub is missing and the build fails. Clean that up: - Compile hv_apic.c only when CONFIG_X86_64=y - Make the stub for hv_init_apic() available when CONFG_X86_64=n Fixes: 6b48cb5f8347 ("X86/Hyper-V: Enlighten APIC access") Reported-by: kbuild test robot <lkp@intel.com> Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Cc: K.

x86/hyperv: Enable PV qspinlock for Hyper-V Implement the required wait and kick callbacks to support PV spinlocks in Hyper-V guests. [ tglx: Document the requirement for disabling interrupts in the wait() callback. Remove goto and unnecessary includes. Add prototype for hv_vcpu_is_preempted().
