boot images for x86. This will be enhanced to generate all the other
images (u-boot, powerpc CHRP, etc).
At the moment, it's only generating three of them. zfs+gpt+legacy
works with qemu:
qemu-system-x86_64 --drive file=${file},format=raw -serial telnet::4444,server
but the ufs ones still have issues I'm tracking down.
These images are the boot blocks, /boot/loader, a kernel, maybe a
couple of modules, /sbin/init, /bin/sh, /libexec/ld-elf.so, libc.so,
libedit and libncursesw. This is just enough to get to single user. At
the moment, these come from the host system, but should come from
OBJTOP.
At the moment, this requires root to build since the zfs tools require
it (and GELI will too when we add support for that).

this will be installed into /usr/sbin, but for now it's just used for
the boot loader regression script. It's still a bit green, and likely
will get edge cases wrong still. It's also x86 centric at the moment,
but will be enhanced shortly for u-boot, CHRP PowerPC and other
methods.

Currently Facility Unavailable is absent and once an application
tries to use or access a register from a feature disabled in the
CPU it causes a kernel panic.
A simple test-case is:
int main() { asm volatile ("tbegin.;"); }
which will use TM (Hardware Transactional Memory) feature which
is not supported by the kernel and so will trigger the following
kernel panic:
----
fatal user trap:
exception = 0xf60 (unknown)
srr0 = 0x10000890
srr1 = 0x800000000000f032
lr = 0x100004e4
curthread = 0x5f93000
pid = 1021, comm = htm
panic: unknown trap
cpuid = 40

cpuid = 40
Uptime: 3m18s

Since Hardware Transactional Memory is not yet supported by FreeBSD, treat
this as an illegal instruction.

Load the kernel eflags less magically, as in locore. The magic increased
when I removed eflags from the pcb in r305899.
Remove a jump to low memory that became garbage when the i386 version was
mostly replaced by the amd64 version in r235622.
The amd64 version is very similar. It still loads the flags magically,
but is not missing comments about using the special page table.

If a route is modified in a way that changes the route's source
address (i.e. the address used to access the gateway), then a
reference on the ifaddr representing the old source address will
be leaked if the address type does not have an ifa_rtrequest
method defined. Plug the leak by releasing the reference in
all cases.

This was an experiment that landed in the wrong branch and was pushed
accidentally. It's best if it is ignored because the difference was
due to vers.o being different, not float.o... And it was confirmed to

temporary workaround. This fixes zfs booting generally, but breaks all
GELI booting by default. Add note to UPDATING to this effect. When the
GELI issues are resolved, this will be reverted.
We need to include ficl.h after the standard includes, rather than
before them. It changes the generated code in ways that haven't been
completely analyized. This restores the old code generation (as
verified by md5 changing back for zfsloader).
This should restore GPT + ZFS and GPT + ZFS + GELI booting that was
broken in r326585 (or would have been if r326584 hadn't broken the
build).

The vnode might be reclaimed after unlock, so v_mount becomes NULL.
Cache the struct mount pointer before the unlock, the struct is
type-stable.
Note that devfs_allocv() reads mp->mnt_data but does not operate on it
further when dirent is doomed. The unmount cannot proceed until all
dirents are reclaimed.

- Add the BCM4322X D11 core revision and missing BCM43224 PCI device ID to
our device tables.
- Disable the DMA engine parity check (rather than adding parity support
to the to-be-replaced bwn(4) DMA implementation).
Currently, N-PHY support in bwn(4) is GPL licensed, and is not included by
default. Until this is replaced with Broadcom's ISC-licensed N-PHY
implementation, bwn(4) must be rebuilt to enable N-PHY support.
To build bwn(4) with N-PHY support, add the following lines to your kernel
configuration file and rebuild the kernel (and modules):
options BWN_GPL_PHY
To test bwn(4) with a BCM43224/BCM43225 device, install the firmware from
the net/bwn-firmware-kmod port, and place the following lines in
loader.conf(5):
hw.bwn_pci.preferred="1"
if_bwn_pci_load="YES
bwn_v4_ucode_load="YES"

Official Linux dts's put the individual portals under a simple-bus, rather

Don't create a dummy __tls_get_addr.
We just don't need one with the current setup.
We only error on undefined references that are used by some
relocation.
If we managed to relax all uses of __tls_get_addr, no relocation uses
it and we don't produce an error.
This is less code and fixes the case were we fail to relax. Before we
would produce a broken output, but now we produce an error.
Pull in r320390 from upstream lld trunk (by Rafael Espindola):
Create reserved symbols early so they can be versioned.
This fixes pr35570.
We were creating these symbols after parsing version scripts, so they
could not be versioned.
We cannot move the version script parsing later because we need it for
lto.
One option is to move both addReservedSymbols and
createSyntheticSections earlier. The disadvantage is that some
sections created by createSyntheticSections replace other input
sections. For example, gdb index replaces .debug_gnu_pubnames, so it
wants to run after gc sections so that it can set S->Live to false.
What this patch does instead is to move just the ElfHeader creation
early.
Pull in r320412 from upstream lld trunk (by Rafael Espindola):
Handle symbols pointing to output sections.
Now that gc sections runs after linker defined symbols are added it
