Throughout the network stack we have a few places of
if (jailed(cred))
left. If you are running with a vnet (virtual network stack) those will
return true and defer you to classic IP-jails handling and thus things
will be "denied" or returned with an error.
Work around this problem by introducing another "jailed()" function,
jailed_without_vnet(), that also takes vnets into account, and permits
the calls, should the jail from the given cred have its own virtual
network stack.
We cannot change the classic jailed() call to do that, as it is used
outside the network stack as well.

Add a few more V_hacks to nfsclient to allow machines with a VIMAGE
kernel to boot from NFS. [1]
Note: this is not a full virtualization of nfsclient. It is only does
what advertised above and nothing more.
Properly support -fPIE by linking PIE binaries with specially-built
Scrt1.o instead of crt1.o, since the later is built as non-PIC.
Separate i386-elf crt1.c into the pure assembler part and C code,
supplying all data extracted by assembler stub as explicit parameters.
Hide and localize _start1 symbol used as an interface between asm and
C code.
used within FreeBSD base system only, and discourage user applications
from using it. User applications should use the expat version from the
ports/package collection.

Remove duplicate devstat_start_transaction_bio() call. It is already called
from geom_disk. Dulicate call causes wrong queue depth and busy accounting.
This is similar to the Solaris utility of the same name.
Some use cases:
* rc.subr's wait_for_pids
* interactive use, e.g. to shut down the computer when some task is done
even if the task is already running
- Cleanup kernel messages, mostly PMP.
- Took references on devices, while PMP reinitializes them, to not let them
go and distort freeze reference counting.

Fix copy & paste error and remove extra space before colon.
r199608:
Remove unnecessary structure packing.
r199609:
Add initial endianness support. It seems the controller supports
both big-endian and little-endian format in descriptors for Rx path
but I couldn't find equivalent feature in Tx path. So just stick to
little-endian for now.
r199610:
Because we know received bytes including CRC there is no reason to
call m_adj(9). The controller also seems to have a capability to
strip CRC bytes but I failed to activate this feature except for
loopback traffic.
r199611:
Add IPv4/TCP/UDP Tx checksum offloading support. It seems the
controller also has support for IP/TCP checksum offloading for Rx
path. But I failed to find to way to enable Rx MAC to compute the
checksum of received frames.
r199612:
Add __FBSDID.
r199613:
Only Tx checksum offloading is supported now. Remove experimental
code sneaked in r199611.
r199558:
Use bus_{read,write}_4 rather than bus_space_{read,write}_4.
r199561:
Use capability pointer to access PCIe registers rather than
directly access them at fixed address. Frequently the register
offset could be changed if additional PCI capabilities are added to
controller.
One odd thing is ET_PCIR_L0S_L1_LATENCY register. I think it's PCIe
link capabilities register but the location of the register does
not match with PCIe capability pointer + offset. I'm not sure it's
shadow register of PCIe link capabilities register.
Remove complex macros that were used to compute bits values.
Although these macros may have its own strength, its complex
definition make hard to read the code.

This applies to both the $() and `` forms but is most useful for ``

o Properly support M5229 revision 0xc7 and 0xc8:
- These revisions no longer have cable detection capability.
- The UDMA support bit of register 0x4b has been dropped without an
replacement.
- According to Linux it's crucial for working ATAPI DMA support to
also set the reserved bit 1 of regsiter 0x53 with these revisions.
o Only set ATA_CHECKS_CABLE for chip versions that actually support
cable detection, i.e. neither for ALI_OLD nor for ALI_NEW revisions
>= 0xc7.
Specify the capability and media bits of the capabilities page in
native, i.e. big-endian, format and convert as appropriate like we
also do with the multibyte fields of the other pages. This fixes
the output of acd_describe() to match reality on big-endian machines
without breaking it on little-endian ones. While at it, also convert
the remaining multibyte fields of the pages read although they are
currently unused for consistency and in order to prevent possible
similar bugs in the future.
Change gcore in order to get rid of the procfs support and use FreeBSD's
specific interfaces. Main changes:
- now gcore recognizes threads within the the process and handle dumps on
a thread scope
- the process to be analyzed should be stopped while gcore runs
- gcore may not work with processes that are being debugged with gdb or
truss
- ptrace may let interruptible calls to return EINTR, thus dirtying
signals handling within the process
