- Cleanup kernel messages, mostly PMP.
- Took references on devices, while PMP reinitializes them, to not let them
go and distort freeze reference counting.
r199563:
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 ``
because the other line number is relative to the enclosed text there.
(For older versions, -v can be used as a workaround.)

Compile libgcov without stack protection. It can be linked into
both static and dynamic binaries compiled with or without stack
protection and should not depend on libssp_nonshared.a symbols.

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

Use kern_sigprocmask() instead of direct manipulation of td_sigmask to
reschedule newly blocked signals.
MFC r198590:
Trapsignal() calls kern_sigprocmask() when delivering catched signal
with proc lock held.
MFC r198670:
For trapsignal() and postsig(), kern_sigprocmask() is called with
both process lock and curproc->p_sigacts->ps_mtx locked. Prevent lock
recursion on ps_mtx in reschedule_signals().
In kern_sigsuspend(), manipulate thread signal mask using
kern_sigprocmask(). Also, do cursig/postsig loop immediately after
waiting for signal, repeating the wait if wakeup was spurious due to
race with other thread fetching signal from the process queue before us.
MFC r199136:
Use cpu_set_syscall_retval(9) to set syscall result, and return
EJUSTRETURN from kern_sigsuspend() to prevent syscall return code from
modifying wrong frame.
Take care of possibility that pending SIGCONT might be cancelled by
SIGSTOP, causing postsig() not to deliver any catched signal.
Note that r200091 completely overrides r200053 and the merge of the
former is recorded for bookkeeping only.
r200091 won't be merged to 'more stable' branche(s) because of the POLA.
Put process-directed signals to the process queue unconditionally,
selecting the thread to deliver the signal only by the thread returning
to usermode.
Change cursig() and postsig() to look both into the thread and process
signal queues.

Don't warn about an RSDP with a corrupt checksum. The kernel does a better

Fix a confusing typo in the EDD packet structure used in gptboot and
gptzfsboot. I got the segment and offset fields reversed in the structure,
but I also succeeded in crossing the assignments so the actual EDD packet
ended up correct.
- Port bios_getmem() from libi386 to {gpt,}zfsboot() and use it to
safely allocate a heap region above 1MB. This enables {gpt,}zfsboot()
to allocate much larger buffers than before.
- Use a larger buffer (1MB instead of 128K) for temporary ZFS buffers. This
allows more reliable reading of compressed files in a raidz/raidz2 pool.
- Various small whitespace and style fixes.
- Improve the algorithm the loader uses to choose a memory range for its
heap when using a range above 1MB.
Properly return an error reply if an NFS remove or link operation fails.
Previously the failing operation would allocate an mbuf and construct an
error reply, but because the function did not return 0, the NFS server
assumed it had failed to generate a reply and would leak the reply mbuf as
well as not sending the reply to the NFS client.
