gtaskqueue: Fix a typo
This is a no-op in practice since gtaskqueue_thread_enqueue() and
taskqueue_thread_enqueue() are identical, and while _gtaskqueue_create()
compares the enqueue callback pointer with gtaskqueue_thread_enqueue(),
the result has no effect since TQ_FLAGS_UNLOCKED_ENQUEUE was copied
directly from subr_taskqueue.c and is unused in the gtaskqueue code.
Fix it anyway since it's a bug. More generally we really need to
consolidate subr_taskqueue.c and subr_gtaskqueue.c.

The kern.pid_max_limit will hold the PID_MAX value the kernel was

copy_file_range.2: Clarify that only regular files work
PR#273962 reported that copy_file_range(2) did not work
on shared memory objects and returned EINVAL.
Although the reporter felt this was incorrect, it is what
the Linux copy_file_range(2) syscall does.
Since there was no collective agreement that the FreeBSD
semantics should be changed to no longer be Linux compatible,
copy_file_range(2) still works on regular files only.
This man page update clarifies that. If, someday, copy_file_range(2)
is changed to support non-regular files, then the man page will
need to be updated to reflect that.

llvm: Support: don't block signals around close if it can be avoided
Signal blocking originally showed up in 51c2afc4b65b2782 ("Support:

there are systems where the error is known to be fine.
This commit elides signal blocking for said systems (the list is

isp(4): Rework firmware handling/loading
Correctly identify the active firmware in flash on adapters with
primary and secondary firmware region in flash.
Correctly identify the active NVRAM on adapters with primary
and secondary NVRAM region in flash.
Loading ispfw(4) moved from isp_pci_attach() to isp_reset().
Drop the reference to ispfw(4) after using it so one can kldunload(8) it.
New isp_load_ram() function to load either ispfw(4) or flash firmware
into RISC's RAM.
New functions to read data from flash. The old ones will be removed later.
A bunch of new helper functions to identify and validate active flash
regions for firmware, auxiliary and NVRAM.
Overhaul ISP_FW_* macros and make use of it when comparing firmware
versions. We can handle firmware versions up to 255.255.255.
Firmware load priority slightly changed:
For 27xx and newer adapters:
- load ispfw(4) firmware
- request (active) flash firmware information
- compare version numbers of ispfw(4) and flash firmware
- load firmware with highest version into RISC's RAM
- if loading ispfw(4) is disabled or failed - load firmware from flash
- if everything else fails use MBOX_LOAD_FLASH_FIRMWARE as fallback
For 26xx and older adapters nothing changed:
- load ispfw(4) firmware and load it into RISC's RAM
- if loading ispfw(4) is disabled or failed use MBOX_EXEC_FIRMWARE
- for 26xx a preceding MBOX_LOAD_FLASH_FIRMWARE is used
New read only sysctl(8)'s:
dev.isp.N.fw_version_run: the firmware version actually running
dev.isp.N.fw_version_ispfw: the firmware version provided by ispfw(4)
dev.isp.N.fw_version_flash: the (active) firmware version in flash
While here:
- firmware attribute handling/parsing reworked
+ renamed defines from ISP2400_FW_ATTR_* to ISP_FW_ATTR_*
+ changed values to match new handling/parsing
+ added some more attributes
- enable FLT support on 26xx based adapters
- log level adjustments
- new function return status codes (some for now, some for later use)
- some minor style changes
Tested and approved to work on real hardware with:
- Qlogic ISP 2532 (QLogic QLE2560 8Gb FC Adapter)
- Qlogic ISP 2031 (QLogic QLE2662 16Gbit 2Port FC Adapter)
- Qlogic ISP 2722 (QLogic QLE2690 16Gb FC Adapter)

cam: Let cam_periph_unmapmem() return an error
As of commit b059686a71c8, cam_periph_unmapmem() can legitimately fail
if the copyout() operation fails. However, this failure was never
signaled to upper layers. In practice it is unlikely to occur
since cap_periph_mapmem() would most likely fail in such
circumstances anyway, but an error is nonetheless possible.
However, some code reading revealed a few paths where the return value
of cam_periph_mapmem() is not checked, and this is definitely a bug.
Add error checking there and let cam_periph_unmapmem() return errors
from copyout().

sysctl dev.ena.<device index>.customer_metrics

ena: Add sysctl support for spreading IRQs
This commit allows spreading IO IRQs over different CPUs through sysctl.
Two sysctl nodes are introduced:
1- base_cpu: servers as the first CPU to which the first IO IRQ
will be bound.
2- cpu_stride: sets the distance between every two CPUs to which every
two consecutive IO IRQs are bound.
For example for doing the following IO IRQs / CPU binding:
Run the following commands:
sysctl dev.ena.<device index>.irq_affinity.base_cpu=0
sysctl dev.ena.<device_index>.irq_affinity.cpu_stride=2
Also introduced rss_enabled field, which is intended to replace
'#ifdef RSS' in multiple places, in order to prevent code duplication.
We want to bind interrupts to CPUs in case of rss set OR in case
the newly defined sysctl paremeter is set. This requires to remove a
couple of '#ifdef RSS' as well in the structs, since we'll be using the
relevant parameters in the CPU binding code.

vtnet: Better adjust for ethernet alignment.
Move adjustment of the mbuf from where we allocate it to where we are
about to queue it to the device. Do this only on those platforms that
require it. This allows us to receive an entire jumbo frame on other
platforms. It also doesn't make the adjustment on subsequent frames when
we queue mulitple mbufs for LRO operations.
For the normal use case on armv7, there's no difference because we only
ever allocate one mbuf. However, for the LRO cases it increases what's
available in LRO. It also ensure that we get enough mbufs in those cases
as well (though I have no ability to test this on a LRO scenario with
armv7).
This has the side effect of reverting 527b62e37e68.
