this is a rework of the microcode splitup in tip/x86/microcode (1) I think this new interface is cleaner (look at the changes in 'struct microcode_ops' in microcode.h); (2) it's -64 lines of code; Signed-off-by: NIngo Molnar <mingo@elte.hu>

microcode_amd.c uses ">> 32" on a 32-bit value, so gcc warns about that.

This is the 1st patch in the series. Here the aim was to avoid any significant changes, logically-wise. So it's mainly about generic interface refactoring: e.g. make microcode_{intel,amd}.c more about arch-specific details and less about policies like make-sure-we-run-on-a-target-cpu (no more set_cpus_allowed_ptr() here) and generic synchronization (no more microcode_mutex here). All in all, more line have been deleted than added. 4 files changed, 145 insertions(+), 198 deletions(-) Signed-off-by: NDmitry Adamushko <dmitry.adamushko@gmail.com> Signed-off-by: NIngo Molnar <mingo@elte.hu>

Alexey Dobriyan reported trouble with LTP with the new fast-gup code, and Johannes Weiner debugged it to non-page-aligned addresses, where the new get_user_pages_fast() code would do all the wrong things, including just traversing past the end of the requested area due to 'addr' never matching 'end' exactly. This is not a pretty fix, and we may actually want to move the alignment into generic code, leaving just the core code per-arch, but Alexey verified that the vmsplice01 LTP test doesn't crash with this.

lguest uses a Waker process to break it out of the kernel (ie. actually running the guest) when file descriptor needs attention. Changing this from a process to a thread somewhat simplifies things: it can directly access the fd_set of things to watch. More importantly, it means that the Waker can see Guest memory correctly, so /dev/vring file descriptors will work as anticipated (the alternative is to actually mmap MAP_SHARED, but you can't do that with /dev/zero).

Since the correct timeout value varies, use a heuristic which adjusts the timeout depending on how many packets we've seen.

virtio_ring has the ability to suppress notifications. This prevents a guest exit for every packet, but we need to set a timer on packet receipt to re-check if there were any remaining packets. Here are the times for 1G TCP Guest->Host with different timeout settings (it matters because the TCP window doesn't grow big enough to fill the entire buffer): Timeout value Seconds Xmit/Recv/Timeout None (before) 25.3784 xmit 7750233 recv 1 2500 usec 62.5119 xmit 207020 recv 2 timeout 207020 1000 usec 34.5379 xmit 207003 recv 2 timeout 207003 750 usec 29.2305 xmit 207002 recv 1 timeout 207002 500 usec 19.1887 xmit 561141 recv 1 timeout 559657 250 usec 20.0465 xmit 214128 recv 2 timeout 214110 100 usec 19.2583 xmit 561621 recv 1 timeout 560153 (Note that these values are sensitive to the GSO patches which come later, and probably other traffic-related variables, so take with a large grain of salt).

If you've got a nice DHCP configuration which maps MAC addresses to specific IP addresses, then you're going to want to start your guest with one of those MAC addresses. Also, in Fedora, we have persistent network interface naming based on the MAC address, so with randomly assigned addresses you're soon going to hit eth13. Who knows what will happen then! Allow assigning a MAC address to the network interface with e.g. --tunnet=bridge:eth0:00:FF:95:6B:DA:3D or: --tunnet=192.168.121.1:00:FF:95:6B:DA:3D which is pretty unintelligable, but ...

Ron Minnich noticed that guest userspace gets a GPF when it tries to int3: we need to copy the privilege level from the guest-supplied IDT to the real IDT. int3 is the only common case where guest userspace expects to invoke an interrupt, so that's the symptom of failing to do this.
