Previously the linker emulation was only passed when building binary
objects for firmware modules. This change always passes the desired
output format for kernel modules and kernels rather than requiring the
toolchain's default output format to match the desired output format.
This in turn permits use of external toolchains whose default output
format does not match the desired output format.

Rather than the global NAME_MAX constant. This change is required to
support systems with a NAME_MAX/MAXNAMLEN that differs from UFS_MAXNAMLEN.
This was missed in r313475 due to the alternative spelling ("NAME_MAX") of
MAXNAMLEN. This change is also similar in spirit to r313780.

destination addresses. Previous code has used only destination address
for lookup. But for inbound packets the source address was used as SA
destination address. Thus only outbound SA were used for both directions.
Now we use addresses from a packet as is, thus SAs for both directions are
needed.

The tsec_error_intr_locked() is called with the global lock owned (e.g.
the transmit and the receive lock are both owned). We must not call
tsec_receive_intr_locked() while owning the transmit lock. The normal
receive interrupt takes care that frames are received, this is none of
the business of the error interrupt.

When a member of a RAIDZ has been replaced with a device smaller than the
original, then the top level vdev can report its expand size as 16.0E.
The reduced child asize causes the RAIDZ to have a vdev_asize lower than its
vdev_max_asize which then results in an underflow during the calculation of
the parents expand size.
Fix this by updating the vdev_asize if it shrinks, which is already
protected by a check against vdev_min_asize so should always be safe.
Also for RAIDZ vdevs, ensure that the sum of their child vdev_min_asize is
always greater than the parents vdev_min_size.

The module is designed for modification of a packets of any protocols.
For now it implements only TCP MSS modification. It adds the external
action handler for "tcp-setmss" action.
A rule with tcp-setmss action does additional check for protocol and
TCP flags. If SYN flag is present, it parses TCP options and modifies
MSS option if its value is greater than configured value in the rule.
Then it adjustes TCP checksum if needed. After handling the search
continues with the next rule.

mode. This works around bugs in at least 2 Intel BIOSes for our
subsequent setting of the DAC back to 8-bit mode. The bug caused dark
(mostly 1/4-intensity) colors for all except the first setting to a
VESA graphics mode (including for settings to the current mode).
Remove restoration (with less bits) of the palette in vesa_unload()
after resetting the DAC to 6-bit mode. Depend on the BIOS to keep
the palette consistent with the DAC for the simpler reset case like
we do everywhere else in places that are actually important.
Setting the video mode should reset everything to defaults, although
we usually don't want that. Even the buggy BIOSes set the DAC to the
default 6-bit mode, and set the palette to a default that matches the
DAC. We don't undo the reset for most things, but we do undo it for
the DAC (more precisely, we change to an 8-bit DAC if possible, and
this is the only way that we set to an 8-bit DAC; it is accidental
that if the DAC was in 8-bit mode from a previous mode switch then
setting it to 8-bit mode is an undo). The buggy BIOSes are confused
by our setting of the DAC to 8-bit mode in the "undo" case. They
should multiply palette entries by 4 to match, but they actually leave
all palette entries except #2 (green) and #248-255 (unused) untouched.
Green is mysteriously scaled from 0x2a to 0x6a, and #248-255 are scaled
correctly.
Our support for the 8-bit DAC had almost no effect except to enable
bugs. Syscons barely supports 16 colors, so it doesn't benefit much
from having a palette with 16 million colors instead of only 256K.
Applications can manage the palette using FBIO_{GET,SET}PALETTE, but
the palette managed by this is only used in the less interesting modes
(text and non-truecolor graphics modes up to 8 bits wide), and the
kernel loses the changes on any mode switch (including to another vt
in a different mode).
so overflow can still occur. Fix that. Also remove the extra check for
tv_sec size as under COMPAT_LINUX32 it is always true.

passed in from u-boot across the call to self_reloc and any other early-init
code, and restore them before calling main().
The self_reloc() routine uses r0 and r1 (and calling it uses lr), and
depending on what values get left in them, main() would intermittantly lock
up trying to interpret them as argc and argv values. This problem affected
the self-relocatable ubldr.bin but not ubldr (the elf version).
FreeBSD's DTS contained only one PL050 node and driver considered it to
be PS/2 keyboard. In reality PL050 is a PS/2 port that pushes bytes to/from
the periphers connected to it. New DTS contains two nodes and QEMU emulates
keyboard connected to port #0 and mouse connected to port #1. Since there
is no way to say what's connected to port by checking DTS we hardcode
this knowledge in the driver: it assumes keyboard on port #0 and ignores
port #1 altogether.
Also QEMU defaults emulated keyboard to scan code set 2 while driver used
to work with scan code set 1 so when initializing driver make sure keyboard
is switched to scan code set 1
Scope of this change is somewhat larger than just converting to INTRNG.
The reason for this is that INTRNG support required switching from custom
to upstream DTS because custom DTS didn't have interrup routing information.
This switch caused rewrite of PCI and CLCD drivers and adding SCM module.
List of changes in this commit:
- Enable INTRNG and switch to versatile-pb.dts
- Add SCM driver that controls various peripheral devices like LCD or
PCI controller. Previously registers required for power-up and
configuring peripherals were part of their respective nodes. Upstream
DTS has dedicated node for SCM
- Convert PL190 driver to INTRNG
- Convert Versatile SIC (secondary interrupt controller) to INTRNG
- Refactor CLCD driver to use SCM API to power up and configuration
- Refactor PCI driver to use SCM API to enable controller
- Refactor PCI driver to use interrupt map provided in DTS for
interrupt routing. As a result it fixes broken IRQ routing and
it's no longer required to run QEMU with "-global versatile_pci.broken-irq-mapping=1"
