eabf894627 Optimize zero_page for book-e mmu.
Instead of indirectly calling bzero() through mmu_booke_zero_page_area, zero the
full page the same way as the AIM pmap logic does: using dcbz.

459021cc7d Rewrite tid_flush() in C.
There's no need for it to be in asm.  Also, by writing in C, and marking it
static in pmap.c, it saves a branch to the function itself, as it's only used in
one location.  The generated asm is virtually identical to the handwritten code.

thread creation and destruction. Newly created threads will stop to report
PL_FLAG_BORN before returning to userland and exiting threads will stop to
report PL_FLAG_EXIT before exiting completely. Both of these events are
only enabled and reported if PT_LWP_EVENTS is enabled on a process.

4d43e76fb2 Bring some of the recent locore-v4.S improvements into locore-V6...
- Map all 4GB as VA=PA so that args passed in from a bootloader can
   be accessed regardless of where they are.
 - Figure out the kernel load address by directly masking the PC rather
   then by doing pc-relative math on the _start symbol.
 - For EARLY_PRINTF support, map device memory as uncacheable (no-op for
   ARM_NEW_PMAP because all TEX types resolve to uncacheable).

fcf8d36c46 hyperv: vmbus: run non-blocking message handlers in vmbus_msg_swintr()
We'll remove the per-channel control_work_queue because it can't properly
do serialization of message handling, e.g., when there are 2 NIC devices,
vmbus_channel_on_offer() -> hv_queue_work_item() has a race condition:
for an SMP VM, vmbus_channel_process_offer() can run concurrently on
different CPUs and if the second NIC's
vmbus_channel_process_offer() -> hv_vmbus_child_device_register() runs
first, the second NIC's name will be hn0 and the first NIC's name will
be hn1!

We can fix the race condition by removing the per-channel control_work_queue
and run all the message handlers in the global
hv_vmbus_g_connection.work_queue -- we'll do this in the next patch.

With the coming next patch, we have to run the non-blocking handlers
directly in the kernel thread vmbus_msg_swintr(), because the special
handling of sub-channel: when a sub-channel (e.g., of the storvsc driver)
is received and being handled in vmbus_channel_on_offer() running on the
global hv_vmbus_g_connection.work_queue, vmbus_channel_process_offer()
invokes channel->sc_creation_callback, i.e., storvsc_handle_sc_creation,
and the callback will invoke hv_vmbus_channel_open() -> hv_vmbus_post_message
and expect a further reply from the host, but the handling of the further
messag can't be done because the current message's handling hasn't finished
yet; as result, hv_vmbus_channel_open() -> sema_timedwait() will time out
and th device can't work.

Also renamed the handler type from hv_pfn_channel_msg_handler to
vmbus_msg_handler: the 'pfn' and 'channel' in the old name make no sense.

47f175b846 hyperv: vmbus: remove the per-channel control_work_queue
Now vmbus_channel_on_offer() -> vmbus_channel_process_offer() can
safely run on the global hv_vmbus_g_connection.work_queue now.

We remove the per-channel control_work_queue to achieve the proper
serialization of the message handling.

I removed the bogus TODO in vmbus_channel_on_offer(): a vmbus offer
can only come from the parent partition, i.e., the host.
