lguest doesn't work on kernel 2.6.23-rc1
Hi, all, I have difficulty on setting up lguest. Basic OS info:
gcc 4.1.2
glibc: 2.5.1
binutils: 2.17
kernel: 2.6.23-rc1
Following lguest.txt instruction, I build lguest enaled kernel,
disable CONFIG_COMPAT_VDSO, the host kernel boot fine, but when
booting Qemu image using lguest laucher program, the guest kernel
vmlinux panic, attached console.txt is console output, and config.txt
is kernel

[patch 00/17] paravirt_ops updates
Hi Andi,
This series of patches updates paravirt_ops in various ways. Some of the
changes are plain cleanups and improvements, and some add some interfaces
necessary for Xen.
The brief overview:
add-MAINTAINERS.patch - obvious
remove-CONFIG_DEBUG_PARAVIRT.patch - no longer needed
paravirt-nop.patch - mark nop operations consistently
paravirt-pte-accessors.patch - operations to pack/unpack
