- Move CAP_BINDAT and CAP_CONNECTAT rights to index 0 so we can include
CAP_LOOKUP right in them.

that as all moved rights are not used yet.
r258181:
Replace CAP_POLL_EVENT and CAP_POST_EVENT capability rights (which I had
a very hard time to fully understand) with much more intuitive rights:
CAP_EVENT - when set on descriptor, the descriptor can be monitored
with syscalls like select(2), poll(2), kevent(2).
CAP_KQUEUE_EVENT - When set on a kqueue descriptor, the kevent(2)
syscall can be called on this kqueue to with the eventlist
argument set to non-NULL value; in other words the given
kqueue descriptor can be used to monitor other descriptors.
CAP_KQUEUE_CHANGE - When set on a kqueue descriptor, the kevent(2)
syscall can be called on this kqueue to with the changelist
argument set to non-NULL value; in other words it allows to
modify events monitored with the given kqueue descriptor.
Add alias CAP_KQUEUE, which allows for both CAP_KQUEUE_EVENT and
CAP_KQUEUE_CHANGE.
Add backward compatibility define CAP_POLL_EVENT which is equal to CAP_EVENT.

Change 221534 by rwatson@rwatson_zenith_cl_cam_ac_uk on 2013/01/27
16:05:30
FreeBSD/mips stores page-table entries in a near-identical format
to MIPS TLB entries -- only it overrides certain "reserved" bits
in the MIPS-defined EntryLo register to hold software-defined bits
(swbits) to avoid significantly increasing the page table memory
footprint. On n32 and n64, these bits were (a) colliding with
MIPS64r2 physical memory extensions and (b) being improperly
cleared.
Attempt to fix both of these problems by pushing swbits further
along 64-bit EntryLo registers into the reserved space, and
improving consistency between C-based and assembly-based clearing
of swbits -- in particular, to use the same definition. This
should stop swbits from leaking into TLB entries -- while ignored
by most current MIPS hardware, this would cause a problem with
(much) larger physical memory sizes, and also leads to confusing
hardware-level tracing as physical addresses contain unexpected
(and inconsistent) higher bits.

Loop back the initial commit of 221534 to HEAD. Correct its
implementation for mips32.
Implement a driver for Robert Norton's PIC as an FDT interrupt
controller. Devices whose interrupt-parent property points to a beripic
device will have their interrupt allocation, activation, and setup
operations routed through the IC rather than down the traditional bus
hierarchy.
This driver largely abstracts the underlying CPU away allowing the
PIC to be implemented on CPU's other than BERI. Due to insufficient
abstractions a small amount of MIPS specific code is currently required
in fdt_mips.c and to implement counters.

Add support for PCI-to-ISA LPC bridge emulation. If the LPC bus is attached
to a virtual machine then we implicitly create COM1 and COM2 ISA devices.
Prior to this change the only way of attaching a COM port to the virtual
machine was by presenting it as a PCI device that is mapped at the legacy
I/O address 0x3F8 or 0x2F8.
There were some issues with the original approach:
- It did not work at all with UEFI because UEFI will reprogram the PCI device
BARs and remap the COM1/COM2 ports at non-legacy addresses.
- OpenBSD GENERIC kernel does not create a /dev/console because it expects
the uart device at the legacy 0x3F8/0x2F8 address to be an ISA device.
- It was functional with a FreeBSD guest but caused the console to appear
on /dev/ttyu2 which was not intuitive.
The uart emulation is now independent of the bus on which it resides. Thus it
is possible to have uart devices on the PCI bus in addition to the legacy
COM1/COM2 devices behind the LPC bus.
The command line option to attach ISA COM1/COM2 ports to a virtual machine is
"-s <bus>,lpc -l com1,stdio".
The command line option to create a PCI-attached uart device is:
"-s <bus>,uart[,stdio]"
The command line option to create PCI-attached COM1/COM2 device is:
"-S <bus>,uart[,stdio]". This style of creating COM ports is deprecated.

The TCP delayed ACK logic isn't aware of LRO passing up large aggregated

Doing delayed ACK for LRO segments is bogus for two reasons: a) it pushes
us further away from acking every other packet; b) it introduces additional
delay in responding to the sender. The latter is especially bad because it
is in the nature of LRO to aggregated all segments of a burst with no more
coming until an ACK is sent back.
