f2e5eb368a Improve memory allocation model for rt_msg2() rtsock messages:
* memory is now allocated as early as possible, without holding locks.
 * sysctl users are now guaranteed to get a response (M_WAITOK buffer prealloc).
 * socket users are more likely to use on-stack buffer for replies.
 * standard kernel malloc/free functions are now used instead of radix wrappers.
rt_msg2() has been renamed to rtsock_msg_buffer().

73e46dba11 Turn off the full witness trace on console output.
On head/, or more specifically, when WITNESS is in
the kernel config, the console is spammed excessively
with lock order reversal between isofs and devfs.

Set debug.witness.trace=0 in the installer sysctl.conf
to avoid printing the full KDB stack backtrace.  This
does not prevent printing the lock order reversal has
happened, only lessens the console spam.

faecd0da18 loader's GPT support on BIOS does not seem to like the root filesystem
being the last filesystem on the disk for some reason when made by this

628a40b5c4 Fix the gpio-specifier decoding by respecting the GPIO controller's
#gpio-cells property.

Add a new ofw_bus method (OFW_BUS_MAP_GPIOS()) that allows the GPIO
controller to implement its own mapping to deal with gpio-specifiers,
allowing the decoding of gpio-specifiers to be controller specific.

The default ofw_bus_map_gpios() decodes the linux standard (#gpio-cells =
<2>) and the FreeBSD standard (#gpio-cells = <3>).

It pass the gpio-specifier flag field to the children as an ivar variable so
they can act upon.

a9e285b047 Fix order of libthr and libc in the global dso list for sshd, by
explicitely linking main binary with -lpthread.  Before, libthr
appeared in the list due to dependency of one of the kerberos libs.
Due to the change in ld(1) behaviour of not copying NEEDED entries
from direct dependencies into the link results, the order becomes
reversed.

The libthr must appear before libc to properly interpose libc symbols
and provide working rtld locks implementation.  The symptom was sshd
hanging on rtld bind lock during nested symbol binding from a signal
handler.

4c74acf76a When vm_fault_copy_entry() is called from vm_map_protect() for a wired
entry and performs the upgrade of the entry permissions from read-only
to read-write, we must allow to search for the source pages in the
backing object, like we do in the case of forking the read-only wired
entry. For the fork case, the behaviour is allowed by src_readonly
boolean, which in fact is only used to assert that read-write case
provides all source pages in the top-level object.

Eliminate the src_readonly variable.  Allow for the copy loop to look
into the backing objects, add explicit asserts to ensure that only
read-only and upgrade case actually does.

Expand comments. Change the panic call into assert.

7ff9cf1d06 Disable vga if EFI framebuffer present. vt(9) should handle this internally
based on efifb's higher priority, but it doesn't, and this at least lets
us build a kernel that boots on both BIOS and EFI systems for now.

457b8af283 Add script to setup bootable CD ISOs for both BIOS and EFI systems. Tested
and working on QEMU. Actually using this script as the regular image
generator, like with the memstick one, will require that the kernel support
EFI too. In particular, the following two things are required:
1. vt(9) be the default console driver
2. vt_efifb and vt_vga be able to coexist usefully in the same kernel

One other note here is that this requires newfs_msdos and mdconfig, which is
really ugly. NetBSD's makefs at least seems to support FAT now. If that
actually works, it should be imported and we can get rid of the mdconfig mess.

91c650065a Provide a proper armv7 implementation of icache_sync_all rather than
using armv7_idcache_wbinv_all, because wbinv_all doesn't broadcast the
operation to other cores.  In elf_cpu_load_file() use icache_sync_all()
and explain why it's needed (and why other sync operations aren't).

As part of doing this, all callers of cpu_icache_sync_all() were
inspected to ensure they weren't relying on the old side effect of
doing a wbinv_all along with the icache work.

6b446ed5ab Add EFI support to the installer. This requires that the kernel provide
a sysctl to determine what firmware is in use. This sysctl does not exist
yet, so the following blocks are in front of the wheels:
- I've provisionally called this "hw.platform" after the equivalent thing
  on PPC
- The logic to check the sysctl is short-circuited to always choose BIOS.
  There's a comment in the top of the file about how to turn this off.

If IA64 acquired a boot1.efifat-like thing (probably with very few
modifications), the same code could be adapted there.

define a few imx_ccm_foo() functions that are implemented by the imx51 or

reality, so for now its implementations just return hard-coded numbers.

5280a31478 r261913 broke DES passwords, because the only way they could work,
since they don't have an easily recognizable signature, was if they
were the default.  This commit rewrites crypt_set_format(3) etc to
address this:

 - Use a pointer instead of an index to identify the default format.
   This pointer is initialized at compile time to point to the first
   first element in the list of supported formats, eliminating the
   need for crypt_setdefault().  Using a pointer also simplifies
   iterating through the list.

 - Associate DES with the magic string "_", which takes care of the
   Extended DES format.

 - Finally, as a special case, if the salt does not match any known
   magic string but matches ^[./0-9A-Za-z]{13}$, it is assumed to be a
   DES password and is passed on to crypt_des().
