b20b25e744 cxgbe(4): fix the size of the iq/eq maps.
The firmware can allocate ingress and egress context ids anywhere from
its configured range.  Size the iq/eq maps to match the entire range
instead of assuming that the firmware always allocates the first
available context id.

f85aa85895 [hwpmc] Fix call chain capture for ARM64
Use ELR register value instead of LR for PMC_TRAPFRAME_TO_PC macro since
it's the former that indicates PC if the interrupted execution thread.

This fixes a bug where pmcstat lost the leaf function of the call chain
and started with the second function in the chain.

Although this change is an improvement over the previous logic there is still
posibility for incomplete data: if the leaf function does not have stack
variables and does not call any other functions compiler would not generate
a stack frame for it and the FP value would point to the caller's frame, so
instead of the actual "caller1 -> caller2 -> leaf" chain only
"caller1 -> leaf" would be captured.

c7cffd65c5 Add support for stacked VLANs (IEEE 802.1ad, AKA Q-in-Q).
802.1ad interfaces are created with ifconfig using the "vlanproto" parameter.
Eg., the following creates a 802.1Q VLAN (id #42) over a 802.1ad S-VLAN
(id #5) over a physical Ethernet interface (em0).

ifconfig vlan5 create vlandev em0 vlan 5 vlanproto 802.1ad up
ifconfig vlan42 create vlandev vlan5 vlan 42 inet 10.5.42.1/24

VLAN_MTU, VLAN_HWCSUM and VLAN_TSO capabilities should be properly
supported. VLAN_HWTAGGING is only partially supported, as there is
currently no IFCAP_VLAN_* denoting the possibility to set the VLAN
EtherType to anything else than 0x8100 (802.1ad uses 0x88A8).

44ca4575ea vmapbuf: don't smuggle address or length in buf

always a pointer use a type of void * and cast to vm_offset_t in

take a pointer and check its bounds.)

In no other situtation does b_data contain a user pointer and vmapbuf

c0b5fcf692 Improve FPU Tag Word reconstruction on i386 to indicate register states.
Improve the code reconstructing en_tw in struct fpreg32 from FXSAVE
results so that all register states are indicated correctly.  The
previous code unconditionally mapped non-empty register state to
'normalized value' constant.  The new code explicitly distinguishes
the 'zero value' and 'special value' constants as well.  This improves
consistency between real FSAVE and translation from FXSAVE, and
ensures that tests using PT_GETFPREGS can rely on a single correct
value independently of the underlying implementation.

hashes and in HMAC mode on both amd64 and i386.  It uses the SHA
intrinsics when present similar to aesni(4), but uses SSE/AVX
instructions when they are not.

Note that some files from OpenSSL that normally wrap the assembly
routines have been adapted to export methods usable by 'struct
auth_xform' as is used by existing software crypto routines.

Using assembly directly ensures that symbols can be defined with the

by the C compiler driver, it also avoids the need for all of the

6b7ecdcd9d Re-enable receive flow control for TOE TLS sockets.
Flow control was disabled during initial TOE TLS development to
workaround a hang (and to match the Linux TOE TLS support for T6).
The rest of the TOE TLS code maintained credits as if flow control was
enabled which was inherited from before the workaround was added with
the exception that the receive window was allowed to go negative.
This negative receive window handling (rcv_over) was because I hadn't
realized the full implications of disabling flow control.

To clean this up, re-enable flow control on TOE TLS sockets.  The
existing TPF_FORCE_CREDITS workaround is sufficient for the original
hang.  Now that flow control is enabled, remove the rcv_over
workaround and instead assert that the receive window never goes
negative matching plain TCP TOE sockets.

2ed3236082 Major improvement to build parallelism for googletest internal tests
Currently the googletest internal tests build after the matching library.
However, each of these is serialized at the top level makefile.
Additionally some of the tests (e.g. the gmock-matches-test) take up to
90 seconds to build with clang -O2. Having to wait for this test to
complete before continuing to the next directory seriously slows down the
parllelism of a -j32 build.
Before this change running `make -C lib/googletest -j32 -s` in buildenv
took 202 seconds, now it's 153 due to improved parallelism.

c0baa3dc4a vgonel(): avoid recursing into VOP_INACTIVE().
It is a common pattern for filesystems' VOP_INACTIVE() implementation
to forcibly reclaim the vnode when its state is final.  For instance,
UFS vnode with zero link count is removed, and since it is
inactivated, the last open reference on it is dropped.

On the other hand, vnode might get spurious usecount reference for
many reasons.  If the spurious reference exists while vgonel() checks
for active state of the vnode, it would recurse into VOP_INACTIVE().

Fix it by checking and not doing inactivation when vgone() was called
from inactive VOP.
