| |
Hi Linus,
This series of patches are bugfixes for Xen for 2.6.30. They are:
xen/x86-64: fix breakpoints and hardware watchpoints xen/x86-64: clean up warnings about IST-using traps xen: deal with NMI's use of IST too
Fix breakpoints and watchpoints on x86-64. When running native, breakpoints and watchpoints use the IST mechanism to run on a separate interrupt stack. Xen doesn't support this, and just delivers the interrupts normally. These patches special-case the IST-using interrupts we care about under Xen to use a separate trap gate which expects a standard stack layout. The second patch prints warnings if any other IST-using traps arise in the future.
xen/i386: reserve Xen pagetables xen: reserve Xen start_info rather than e820 reserving
Reserve the Xen-provided pagetables on i386. Previously this was done implicitly because they happened to be in the memory range reserved by something else, but that was cleaned up so we need to do it explicitly. Also, use reserve_early() rather than an e820 reserved region, so there's some documentation in the kernel boot log.
