2019-05-13bcm, bcm64: preserve memsize across reboots, avoid trashing atags while ↵cinap_lenrek
parsing cmdline we override atag memory on reboot, so preserve the memsize learned from atag as *maxmem plan9 variable. the global memsize variable is not needed anymore. avoid trashing the following atag when zero terminating the cmdline string. zero memory after plan9.ini variables.
2019-05-12devip: do not lock selftab in ipselftabread(), remove unused fields from Ipselfcinap_lenrek
the Ipselftab is designed to not require locking on read operation. locking the selftab in ipselftabread() risks deadlock when accessing the user buffer creates a fault. remove unused fields from the Ipself struct.

2019-05-11devip: reset speed and delay on bind, adjust burst on mtu change, ifc->m nil ↵cinap_lenrek
check, consistent error strings initialize the rate limits when the device gets bound, not when it is created. so that the rate limtis get reset to default when the ifc is reused. adjust the burst delay when the mtu is changed. this is to make sure that we allow at least one full sized packet burst. make a local copy of ifc->m before doing nil check as it can change under us when we do not have the ifc locked. specify Ebound[] and Eunbound[] error strings and use them consistently.

2019-05-11devip: remove unused c->car qlock, avoid potential deadlock in ↵cinap_lenrek
ipifcregisterproxy() remove references to the unused Conv.car qlock. ipifcregisterproxy() is called with the proxy ifc wlock'd, which means we cannot acquire the rwlock of the interfaces that will proxy for us because it is allowed to rlock() multiple ifc's in any order. to get arround this, we use canrlock() and skip the interface when we cannot acquire the lock. the ifc should get wlock'd only when we are about to modify the ifc or its lifc chain. that is when adding or removing addresses. wlock is not required when we addresses to the selfcache, which has its own qlock.
2019-05-11devip: avoid media bind/unbind kproc reader startup race, simplify etherbindcinap_lenrek
mark reader process pointers with (void*)-1 to mean not started yet. this avoids the race condition when media unbind happens before the kproc has set its Proc* pointer. then we would not post the note and the reader would continue running after unbind. etherbind can be simplified by reading the #lX/addr file to get the mac address, avoiding the temporary buffer.

2019-05-10bcm64: use exclusive monitor on nrdy to wake up idlehands()cinap_lenrek
when the exclusive monitor is cleared, a event is generated which we can use to wake up idlehands. that way we do not need to wait for the next timer interrupt until a cpu takes work from the run queue.

2019-05-09libc: provide arm64 assembly versions for memmove() and memset()cinap_lenrek
just a first approximation, uses unaligned 8 byte loads and stores. MOVP not yet implemented by the linker. no ZVA cache magic yet.

2019-05-07nusb/usbd: work around devices that ignore the high byte of wLength in ↵cinap_lenrek
control transfer reads there appear to be devices out there such as Realtek RTL2838UHIDIR SDR that do not process control transfers correctly, ignoring the high byte of the wLength field. to work around this, we specify an odd number of bytes for read sizes >= 256 which keeps the low byte 0xFF.

Now, you can safely use them in unbraced if statements, and with char*s.

2019-05-05bootrc: fix $rootdir and $rootspec handling (thanks lucio)cinap_lenrek
we did not interpret the $rootdir and $rootspec environment variables right. $rootdir is what gets bound to / (usually /root) and $rootspec is the mountspec of /root.

2019-05-05usbdwc: enable Slowbuilkin workarround, improve split transaction timing, ↵cinap_lenrek
handle erroring sleep(), debugging i'v been seeing the error condition described above in the Slowbulkin comment. so i'm enabling the work arround which seems to fix the lockup. in the split transaction case where we want to start the transaction at frame start, acquire the ctlr lock *before* checking if we are in the right frame number. so the start will happen atomically. checking the software ctlr->sofchan instead of checking the interrupt mask register seems to be quicker. setting the haint mask bit for the chan under ctlr lock in chanio() instead of chanwait() avoids needing to acquire the ctlr lock twice. mask wakechan bits with busychan bitmap in interrupt handlers so we will not try to wake up released chans by accident. sleep() and tsleep() might get interrupted so we have to release the split qlock in the split transaction case and in all cases, make sure to halt the channel before release. add some common debug functions to dump channel and controller registers.
