[Xen-devel] How can I map a foreign mfn when I'm in a workqueue?

[zhefu jiang <guokeno0@xxxxxxxxx>]

I use alloc_vm_area/direct_kernel_remap_pfn_range/unmap_vm_area to map a foreign pfn into dom0's kernel address space, all goes well with the exception that when I use them in a workqueue, dom0's kernel fails to map the page and gives me these error messages:

 

Unable to handle kernel paging request at xxxxxx...

 

Does anyone have some idea about it?
