* um: Fix PTRACE_POKEUSER on x86_64Richard Weinberger2017-05-201-1/+1
| | | | | | | | | | | | | | | | | commit 9abc74a22d85ab29cef9896a2582a530da7e79bf upstream. This is broken since ever but sadly nobody noticed. Recent versions of GDB set DR_CONTROL unconditionally and UML dies due to a heap corruption. It turns out that the PTRACE_POKEUSER was copy&pasted from i386 and assumes that addresses are 4 bytes long. Fix that by using 8 as address size in the calculation.

* um: Don't pollute kernel namespace with uapiRichard Weinberger2015-06-251-0/+1
| | | | | | | | | Don't include ptrace uapi stuff in arch headers, it will pollute the kernel namespace and conflict with existing stuff. In this case it fixes clashes with common names like R8. Signed-off-by: Richard Weinberger <richard@nod.at>
