commit e2dec0ff9b1e071779bee2c4e6fc82f8194b1c1d
Author: Mark Wielaard <mark@klomp.org>
Date: Sun Jul 26 21:17:23 2020 +0200
Handle REX prefixed JMP instruction.
The NET Core runtime might generate a JMP with a REX prefix.
For Jv (32bit offset) and Jb (8bit offset) this is valid.
Prefixes that change operand size are ignored for such JMPs.
So remove the check for sz == 4 and force sz = 4 for Jv.

commit f4abcc05fdba3f25890a9b30b71d511ccc906d46
Author: Mark Wielaard <mark@klomp.org>
Date: Mon Jul 27 22:43:28 2020 +0200
Incorrect call-graph tracking due to new _dl_runtime_resolve_xsave*
Newer glibc have alternate ld.so _ld_runtime_resolve functions.
Namely _dl_runtime_resolve_xsave and _dl_runtime_resolve_xsave'2
This patch recognizes the xsave, xsvec and fxsave variants and
changes callgrind so that any variant counts as _dl_runtime_resolve.

epoll_ctl warns for uninitialized padding on non-amd64 64bit arches
struct vki_epoll_event is packed on x86_64, but not on other 64bit
arches. This means that on 64bit arches there can be padding in the
epoll_event struct. Seperately the data field is only used by user
space (which might not set the data field if it doesn't need to).
Only check the events field on epoll_ctl. But assume both events
and data are both written to by epoll_[p]wait (exclude padding).

commit a53adb79711ccfc76a4ee32b20253045cdab55c7
Author: Mark Wielaard <mark@klomp.org>
Date: Mon Jul 27 16:36:17 2020 +0200
Handle linux syscalls sched_getattr and sched_setattr
The only "special" thing about these syscalls is that the given
struct sched_attr determines its own size for future expansion.
Original fix by "ISHIKAWA,chiaki" <ishikawa@yk.rim.or.jp>
