curproc that does the locking or unlocking, so the proc parameter is pointless and can be dropped. OK mpi@, deraadt@

therefore all other x86 cpus must pay the performance price of the hazard workaround until Skylake disappears from the ecosystem eventually like 486. This returns your cpu's performance to pre-inflated performance. ok mlarkin guenther
2018-04-27Introduce an helper function to extract endpoint's max burst value.Martin Pieuchot
Use this helper to calculate the Transfer Burst Count (TBC) and Transfer Last Burst Packet Count (TLBPC) required for isochronous support. Note that SS companion descriptors are still not read. While here print the ETE and IST values in debug mode.

2018-04-27The i.MX8M has the same quirk as the i.MX6SX, where the CAP1 registerPatrick Wildt
spills into the CAP register.
2018-04-27Newer fec(4), like implemented on i.MX8M, have multiple interrupt linesPatrick Wildt
to the ethernet controller for different types of events. On the i.MX8M interrupts only seem to happen on the last interrupt, while the i.MX6 that we support very well only has a single interrupt line. Simply establish all three lines (if available) in a non-MPSAFE fashion to make ethernet work on the i.MX8M SoC. ok kettenis@

2018-04-26net80211: stub SIOCS80211SCAN, make ifconfig scan instant.Paul Irofti
The following removes the functionality of the SIOCS80211SCAN ioctl. After long discussions with stps@, mpi@, and deraadt@ we decided that this was the correct way of fixing ifconfig scan from blocking the network stack. The kernel will continue scanning in the background and filling the nodes array, but ifconfig scan commands will now basically do just a SIOCG80211ALLNODES and pretty print the array. So the output stays the same but is instant. In fact, when the interface is freshly brought up, if you type fast enough, you can see the array being filled by running multiple ifconfig scans in sequence. The SIOCS80211SCAN ioctl stays for now as wi(4), pgt(4) and malo(4) still need it around. But not for long... Another change that this introduces is the fact that ifconfig scan no longer plays with UP and DOWN. If the interface is down it complains and exits. This is needed in order to maintain the nodes list. Works on iwm(4), iwn(4), urtwn(4), run(4) and athn(4). Tested by mpi@, landry@, florian@, thanks! OK mpi@.

2018-04-26vmm(4): remove some unnecessary kernel lock code from the SVM guest loopMike Larkin
that is not needed; this code deals with delaying the relocking of the kernel lock until after interrupts are processed during external interrupt exiting, but this is handled differently on SVM. External interrupts are automatically handled by the CPU as soon as stgi() is performed after exit. (The original code came from the VMX/Intel guest loop.) ok guenther@
2018-04-26Remove solock() surrounding PRU_CONTROL in soo_ioctl().Paul Irofti
We do not need the lock there. Missed this in my former commit pushing NET_LOCK() down the stack. Found the hard way by naddy@, sorry! OK mpi@.

2018-04-24vmm(4): fix lockups on SVM hosts when booting Linux guestsMike Larkin
The previous version of the code used "disable_intr" as a protection around the FPU state saving routine, which left host RFLAGS.IF=0 when entering the guest. If the guest ended up in a non-exitable condition, the machine could hang due to missed TLB flush IPIs (and eventual kernel lock contention and starvation). tested by brynet@ ok guenther@
