similar to: [PATCH 008/112] xen: add resend_irq_on_evtchn() definition into events.c.

Remove x86 dependency in drivers/xen/events.c for ia64/xen support introducing include/asm/xen/events.h. Introduce xen_irqs_disabled() to hide regs->flags Introduce xen_do_IRQ() to hide regs->orig_ax. make enum ipi_vector definition arch specific. ia64/xen needs four vectors. Add one rmb() because on ia64 xchg() isn't barrier. Signed-off-by: Isaku Yamahata <yamahata at

Chris, I read with interest your patch for adding support for Xen event channels. I notice that evtchn.h uses an int to represent a port, as demonstrated, for example, in the following two declarations: > +extern void mask_evtchn(int port); > +extern void unmask_evtchn(int port); Using a signed integer is good because negative numbers can be use to return error conditions from functions

This error is not 100% reproducible. However, kernel panic has been occurred many times for last two months. It usually happens when multi VMs (in our case, 14 VMs) are booting together. After we made three big changes to gain more availibility, it began to happen. Changes are : 1. Use *NAS* as vm storage for migration from local disk 2. Use *two bondings* for switch HA (with 4 nics) from

Hi. Recently the xen-ia64 community started to make efforts to merge xen/ia64 Linux to upstream. The first step is to merge up domU portion. This patchset is preliminary for xen/ia64 domU linux making the current xen/x86 domU code more arch generic and adding missing definitions and files. Diffstat: arch/x86/xen/Makefile | 4 +- arch/x86/xen/grant-table.c | 91
