combining marks will have zero advance, but it results in zero-width
glyphs in subfonts. fall back to width so something meaningful is
rendered even if its not combined properly.
when clering smi enable bits in the legacy control/status register,
preserve the reserved bits. clear the RW1C bits.
linux code claims intel xhci controller needs a 1ms delay before
accessing any register after reset.
pcienable() puts a device in fully powered on state
and does some missing initialization that UEFI might
have skipped such as I/O and Memory requests being
disabled.
pcidisable() is ment to shutdown the device, but
currently just disables dma to prevent accidents.
on Samsung ATIV Smart PC Pro XE00T1C-A01CL, the EHCI handoff
causes the system to freeze in UEFI mode as soon as we assert
the os semaphore bit.
until a general solution is found, provide these parameters to
disable the handoff for now as it seems to otherwise work fine.
when a prefix is added with the onlink flag clear, packets
towards that prefix needs to be send to the default gateway
so we omit adding the interface route.
when the on-link flag gets changed to 1 later, we add the
interface route.
the on-link flag is sticky, so theres no way to clear it back
to zero except removing and re-adding the prefix.
automatic Referer headers were found to break downloads from
sourceforge.net, causing html pages to appear instead of tarballs.
if a website does need them, they can be added as needed via hget's -r
flag, or added to mothra.

Once a second rebalance() is called on cpu0 to adjust priorities,
so cpu-bound processes won't lock others out. However it was only
adjusting processes which were running on cpu0. This was observed
to lead to livelock, eg when a higher-priority process spin-waits
for a lock held by a lower priority one.
syntax: reboot!bootfile[!method...]
this echos bootfile to /dev/reboot, causing bootfile kernel
to be started.
when method is given, we first connect to the filesystem and
set bootargs so that bootfile can be loaded from the target
network or local fileserver.
note, when no bootfile is given, this causes the kernel to
reboot to bios.
the end condition port < offset+n could never become
false when offset truncated to 32 bit signed port is
negative. change the condition variables to unsigned
int.
msr's are not byte addressible, so advance reads by
one instead of 8.
Xpipefd wants the pipe descriptor to be closed in turfredir(), so
it pushes the redirection, but this breaks Xpopredir after normal
redirection. so we shuffle the Xpipefd redir to the bottom of the
stack.

little amendments:
- fix line selection (point min/max inversion)
- clear selection when switching linesel/blocksel
- move selection on scroll
the arp table is per interface, so it is possible to have the same
netwrok on multiple physical interfaces, tho with different source
ip address. one example would be a ethernet and a wlan interface.
the mac addresses on these mediums can differ (arp proxying taking
place).
so provide our source address on the interface we received the
request on.
the previous change used the ifcaddr; which is correct; but due to a
oversight in the kernel, had to match the ip of the arp entry.
source address will always work.
unless relay agent (gaddr) is specified, dhcp requests need to
taget a local ip address on the incoming interface or broadcast.
clients might have multiple ethernet interfaces, so we need to
check if any of the ether= attributes in ndb matches. this is
done by passing lookupip() the attribute name and a expected
value and if a match is found, set Info.indb = 1.
remove tohex(), use encodefmt instead. avoid dynamcic allocation.
include interface device in log messages.
sending multicast was broken when ipconfig assigned the 0
address for dhcp as they would wrongly classified as Runi.
this could happen when we do slaac and dhcp in parallel,
breaking the sending of router solicitations.
now handle the supported rates element properly, only
providing the intersecting set of rates that the bss
advertises and what the driver supports, putting the
basic rates first.
also avoid using usupported rates.

nobody passes us the "RSD PTR " address when doing multiboot/kexec
on UEFI systems. so we search for it manually in the ACPI reserved
area as indicated in the e820 memory map.
launch wadfs after detecting main wad, exposing GENMIDI and music lumps
under /mnt/wad. /bin/dmus can then use them directly, and wadfs doesn't

"I sometimes find myself on either slow or data-capped network links where downloading images isn't ideal. Attached is a simple patch to mothra that changes the 'k' command to not only remove already-downloaded images from a page, but also toggle a state such that mothra won't attempt to download images on future visited sites until 'k' is toggled again. This also adds a '-k' flag to mothra which enables the flag at startup." --Jeremy O'Brien<neutral@fastmail.com> on 9fans
the target has to be encoded as a domain name (the individual
name components as separate labels followed by . (empty) label),
not as a literal string.

we did not apply the special case to store 0xFFFF (-0)
in the checksum field when the checksum calculation
returned zero. we survived this for v4 as RFC768 states:

for ipv6 however, the checksum is not optional and receivers
would drop packets with a zero checksum.
during dhcp, ipconfig assigns the null address :: which makes
ipforme() return Runi for any destination, which can trigger
arp resolution when we attempt to reply. so have v4local()
skip the null address and have sendarp() check the return
status of v4local(), avoing the spurious arp requests.
