9e414386d4 kernel: remove dead case from devpipe
This code is checking the return of devwalk for
a walk resulting in a clone of an open pipe file. However,
devclone ensures that the chan we are cloning is not
currently open.

5f49f8ac9c aux/listen: remove special cases for depreciated datakit
The getserv function has remained mostly unchanged since
1ed. These checks are for handling string local ports
or lack thereof. This was used by datakit at the time,
where 'ports' were service strings. This made the default
datakit service 'login' when a connector did not give
a specific service. The checks for directory traversal also
seemed specifically to guard against a connector from providing
a malicious service string. With datakit gone all current protocols
use numerics as ports so these checks and defaults become uneeded.

ecb5eab76b imx8: add xhci driver for the soc
This is mostly a copy of port/usbxhci.c with PCIWADDR() replaced
by PADDR() and the pci specific code stripped out.

This could be refactored at a later time.

There is a gpio line for the main hub reset that needs to be
asserted and some power management functions that are currently
done by u-boot (using "usb start" command).

We will do these ourselfs once we have the infrastructure for
it in place.

22934e123c imx8: add work in progress i.MX8MQ kernel for the mntreform2 laptop
This is a work in progress port to the mntreform2 laptop.

Working so far:

- mmu (same as raspberry pi 3b+)
- arm generic timer
- gicv3
- uart1
- enet

With access to the uart, one can netboot this kernel in u-boot
using the following commands:

> dhcp
> bootm

08a2cd30ba kernel: fix noteid change race condition from devproc while forking (thanks joe7)
devproc allows changing the noteid of another process
which opens a race condition in sysrfork(), when deciding
to inherit the noteid of "up" to the child and calling
pidalloc() later to take the reference, the noteid could
have been changed and the childs noteid could have been
freed already in the process.

this bug can only happen when one writes the /proc/n/noteid
file of a another process than your own that is in the
process of forking.

the noteid changing functionality of devproc seems questinable
and seems to be only used by ape's setpgrid() implementation.

4148ebcf0e mothra: make scrollbar style consistent with other applications
Scrollbar was drawn using a wide dark gutter over a white background
	whereas other applications (window, sam, ...) use a thinner scrollbar with an
	inverse colorscheme.
	This makes the scrollbar more consistent with other 9front applications.

826d64c11c rc: squelch 'Write error' warning
When writing to a large variable in /env, we
spam 'Write error', in spite of the env var
working. This is new behavior, as of commit
b90036a062.

It produces a lot of scary, noisy warnings,
which are probably bogus.

0375d0a3ab git/send: fill in 'theirs' object, even if we miss it
When pushing, git/send would sometimes decide we had all the
objects that we'd need to update the remote, and would try
to pack and send the entire history of the repository. This
is because we only set the 'theirs' ref when we had the object.

If we didn't have the object, we would set a zero hash,
then when deciding if we needed to force, we would think
that we were updating a new branch and send everything,
which would fail to update the remote.

dba98f649c git/merge: preserve exec bit correctly
A while ago, qwx noticed that we clobbered the exec
bit when merging files. This is not what we want, so
we changed the operator precedence to avoid merging
dirty files implicitly.

But we do want to merge, because it's convenient for
maintaining permissions. So, instead, we should do a
3 way merge of the exec bit.

This patch does that, as well as reverting the rollback
of that change.

While we're here, we adjust the timestamps correctly
in git/branch.

This requires changes to git/fs, because without an open
handler, lib9p allows opening any file with any mode,
which confuses 'test -x'.

6949c4a707 git/pull: fetch all branches (please test)
there was a diff that went in a while ago to improve
this, but it got backed out because it encounters a
bug in upstream git -- the spec says that a single
ACK should be sent when not using multi-ack modes,
but they send back multiple ones.

This commit brings back the functionality, and works
around the upstream git bug in two different ways.

First, it skips the packets up until it finds the
start of a pack header.

Second, it deduplicates the want messages, which
is what seems to trigger the duplicate ACKs that
cause us trouble.

f05b8af71e devsd: cache SDunit pointer in Chan.aux, improve error handling
Avoid calling sdgetdev() for every I/O. Instead,
put the SDunit pointer for #S/sdXX/* files in Chan.aux
and keep a reference to SDev between sdopen()/sdclose().

This avoids having to do the sdindex() lookup and
qlock(),incref(),decref() on every read/write
operation. Removal of SDev's is quite rare and only
can happen with pcmcia ide controllers, and i assume
that for that we can assume thet fileservers having
been exited properly and closed their files before
we attempt to remove a device.

The rest is improving waserror() codepaths, making
sure we release the locks for any of the interface
callbacks (verify/online).

Also get rid of tas() and instead only change the
unit's rawopen flag while holding raw qlock.
