Hi Xiantao, I general I think the code in this patch is fine. I have a couple of nit-picking comments: > + if (target_mask&0x1) { The formatting here isn't quite what most of the kernel does. It would be better if you added spaces so it's a little easier to read, ie: if (target_mask & 0x1) { > + p = &__per_cpu_idtrs[cpu][0][0]; > + for (i = IA64_TR_ALLOC_BASE;

Hi Xiantao, Some more nit-picking, though some of this is a bit more important to fixup. Cheers, Jes > +typedef struct thash_data { Urgh! argh!

Hi, I would like to remind people about the Virtualization track at Linux Plumbers Conference 2010, held in Cambridge, MA, November 3-5, 2010. Please note the deadline for submissions is July 19, 2010. LPC is particular well suited for technical presentations, work in progress and subjects that needs discussion and collaboration between communities (kernel, desktop/gfx, virtualization, etc.),
