a36511c287 Move the installer's keymap solution introduced by SVN r259468. The new
location of /etc/rc.local on the install media is more appropriate as it
knows serial vs. non-serial and can also do the change earlier (so that
even the initial Install dialog can benefit from the change).

f83ed22cb6 Plumb the cn_grab and cn_ungrab routines down into the uart
clients. Mask RX interrupts while grabbed on the atmel serial
driver. This UART interrupts every character. When interrupts are
enabled at the mountroot> prompt, this means the ISR eats the
characters. Rather than try to create a cooperative buffering system
for the low level kernel console, instead just mask out the ISR. For
NS8250 and decsendents this isn't needed, since interrupts only happen
after 14 or more characters (depending on the fifo settings). Plumb
such that these are optional so there's no change in behavior for all
the other UART clients. ddb worked on this platform because all
interrupts were disabled while it was running, so this problem wasn't
noticed. The mountroot> issue has been around for a very very long
time.

a883f5eadb drm/ttm, drm/radeon: Replace EINTR/ERESTART by ERESTARTSYS...
... for msleep/cv_*wait() return values, where wait_event*() is used
on Linux. ERESTARTSYS is the return code expected by callers when the
operation was interrupted.

For instance, this is the case of radeon_cs_ioctl() (radeon_cs.c): if
an error occurs, and the code isn't ERESTARTSYS (eg. EINTR), it logs an
error.

Note that ERESTARTSYS is defined as ERESTART, but this keeps callers'
code close to Linux.

9165bf6297 In r248885 I have reduced size of fake uio resid that ng_ksocket(4) passes
to the soreceive(). This exposed a bug. When reading from a raw socket,
when our fake limit is depleted, we receive a truncated mbuf chain, with
m->m_pkthdr.len > m_length(m). The first problem is that MSG_TRUNC was not
handled. The second one is that we didn't reinit uio_resid in our endless
loop (neither flags), and if socket buffer contained several records, then
we quickly deplete our fake limit. The third bug, actually introduced in
r248885, is that MJUMPAGESIZE isn't enough to handle maximum packet that
ng_ksocket(4) can theoretically receive.

Changes:
- Reinit uio_resid and flags before every call to soreceive().
- Set maximum acceptable size of packet to IP_MAXPACKET. As for now the
  module doesn't support INET6.
- Properly handle MSG_TRUNC return from soreceive().

2b22d5cc07 vga_pci: Improve boot display detection
The previous code was checking the "VGA Enable" bit on the video card's
parent PCI-to-PCI bridge only. This didn't work for the case where the
video card is attached to the root PCI bus (ie. the card has no parent
PCI-to-PCI bridge).

Now, the new code:
    1. checks the "VGA Enable" bit on the parent bridge only if it's a
       PCI-to-PCI bridge;
    2. always checks the "I/O" and "Memory address space decoding" bits
       on the video card itself.

However, vendor-specific bits are not used.

This fixes the use of many integrated Radeon cards: without this patch,
we fail to detect them as the boot display and, when radeonkms looks for
the Video BIOS, it skips the shadow copy made by the System BIOS. It
then fails to fully initialize the card, because the shadow copy is the
only way to read the Video BIOS in these situations. A workaround was to
force the boot display selection using the "hw.pci.default_vgapci_unit"
tunable.

A previous version of this patch added a new function doing the checks.
Now, the vga_pci_is_boot_display() function is used to perform the
checks (only until the boot display is found) and return if the given
device is the boot display or not.

Furthermore, vga_pci_attach() logs "Boot video device" if the card being
attached it the Chosen One:
    vgapci0: <VGA-compatible display> [...]
    vgapci0: Boot video device

a6c26592f1 Extend libteken to support CJK fullwidth characters.
Introduce a new formatting bit (TF_CJK_RIGHT) that is set when putting a
cell that is the right part of a CJK fullwidth character. This will
allow drivers like vt(9) to support fullwidth characters properly.

emaste@ has a patch to extend vt(9)'s font handling to increase the
number of Unicode -> glyph maps from 2 ({normal,bold)} to 4
({normal,bold} x {left,right}). This will need to use this formatting
bit to determine whether to draw the left or right glyph.

ba981145d6 Remove several linear list traversals per request from RPC server code.
Do not insert active ports into pool->sp_active list if they are success-
fully assigned to some thread.  This makes that list include only ports that
really require attention, and so traversal can be reduced to simple taking
the first one.

  Remove idle thread from pool->sp_idlethreads list when assigning some
work (port of requests) to it.  That again makes possible to replace list
traversals with simple taking the first element.

ac7e121247 Disable the now unpredicably bogus check for whether we have
eneough queue space before queuing a bunch of IP fragments.

As the comment in the committed change says, in the post-if_transmit(),
post-SMP, post-preemption world, there's just too much overlapping
concurrent code paths and different approaches to driver transmit
queue management to have this code even remotely be effective.

The only specific place it could be useful is if ALTQ is enabled
but again it doesn't at all promise that all the fragments will be
transmitted anyway.

The main reason for committing this change is to disable a parallel
place where the drops counter is incremented.  This is a side effect
of an upcoming change to ixgbe/cxgbe to handle the queue drops
counter slightly better.

The least significant 8 bits of 'pm_flags' are now used for the IPI vector
to use for nested page table TLB shootdown.

Previously we used IPI_AST to interrupt the host cpu which is functionally
correct but could lead to misleading interrupt counts for AST handler. The
AST handler was also doing a lot more than what is required for the nested
page table TLB shootdown (EOI and IRET).

7455eb71a1 Rework flow control for connection-oriented (TCP) RPC server.
When processing receive buffer, write the amount of data, expected
in present request record, into socket's so_rcv.sb_lowat to make stack
aware about our needs.  When processing following upcalls, ignore them
until socket collect enough data to be read and processed in one turn.
  This change reduces number of context switches and other operations
in RPC stack during large NFS writes (especially via non-Jumbo networks)
by order of magnitude.

  After precessing current packet, take another look into the pending
buffer to find out whether the next packet had been already received.
If not, deactivate this port right there without making RPC code to
push this port to another thread just to find that there is nothing.
If the next packet is received partially, also deactivate the port, but
also update socket's so_rcv.sb_lowat to not be woken up prematurely.
  This change additionally reduces number of context switches per NFS
request about in half.
