Cong,
I have updated the PTRACE_VM patches.
The patches have been rebased to linux-2.6.29-rc7 but apply to
linux-2.6.29-rc7-git3.
The set is composed by two patches.
The first one is for all those architectures where PTRACE_SYSCALL is
managed via tracehook (x86, powerpc etc).
Given the wonderful
This patch adds the new PTRACE_VM_SKIPCALL and PTRACE_VM_SKIPEXIT
tags for ptrace's addr parameter.
In this way it is possible to (eventually) get rid of PTRACE_SYSEMU
PTRACE_SYSEMU_SINGLESTEP, while providing not only the same features
but a more general support for Virtual Machines.
Part#1: trace
