3.8.0-rc0 on xen-unstable: RCU Stall during boot as dom0 kernel after IOAPIC
Hi Konrad,
I just tried to boot a 3.8.0-rc0 kernel (last commit: 7313264b899bbf3988841296265a6e0e8a7b6521) as dom0 on my machine with current xen-unstable.
The boot stalls:
[ 0.000000] ACPI: PM-Timer IO Port: 0x808
[ 0.000000] ACPI: Local APIC address 0xfee00000
[ 0.000000] ACPI: LAPIC (acpi_id[0x01] lapic_id[0x00] enabled)
[ 0.000000] ACPI: LAPIC (acpi_id[0x02] lapic_id[0x01]

[PATCH RFC V9 0/19] Paravirtualized ticket spinlocks
This series replaces the existing paravirtualized spinlock mechanism
with a paravirtualized ticketlock mechanism. The series provides
implementation for both Xen and KVM.
Changes in V9:
- Changed spin_threshold to 32k to avoid excess halt exits that are
causing undercommit degradation (after PLE handler improvement).
- Added kvm_irq_delivery_to_apic (suggested by Gleb)
- Optimized halt exit

- Rebased to linux-3.3-rc6.
- used function+enum in place of macro (better type checking)
- use cmpxchg while resetting zero status for possible race

[PATCH V12 0/14] Paravirtualized ticket spinlocks
This series replaces the existing paravirtualized spinlock mechanism
with a paravirtualized ticketlock mechanism. The series provides
implementation for both Xen and KVM.
The current set of patches are for Xen/x86 spinlock/KVM guest side, to be included
against -tip.
I 'll be sending a separate patchset for KVM host based on kvm tree.
Please note I have added the below performance result

This series replaces the existing paravirtualized spinlock mechanism
with a paravirtualized ticketlock mechanism. The series provides
implementation for both Xen and KVM.
Changes in V10:
Addressed Konrad's review comments:
- Added break in patch 5 since now we know exact cpu to wakeup
- Dropped patch 12 and Konrad needs to revert two patches to enable xen on hvm
