card presence and write protect switch detection.
A bridge driver just needs to call the setup routine in its attach(), the
teardown in its detach(), and write a couple tiny glue functions to connect
the sdhci interface functions to the new helper functions. This is not
extensively documented, but multiple examples will exist real soon.
card insert/remove events on controllers that don't implement the insert
and remove interrupts.
Bridge drivers can set a new slot option, SDHCI_NON_REMOVABLE, to indicate
non-removable media (such as eMMC). The sdhci driver will not enable
insert/remove interrupts, and sdhci_generic_get_card_present() will always
return true.
Bridge drivers can set a new quirk, SDHCI_QUIRK_POLL_CARD_PRESENT, and the
sdhci driver will not enable insert/remove interrupts, and instead will use
a callout to poll the card-present status at 5 Hz.
For bridge drivers that get notified of card insert/remove via gpio
interrupts, there is a new sdhci_handle_card_present() function they can
call from the gpio interrupt handler to inform the sdhci code of the event.
In addition to adding these new features, the existing code to debounce card
insertions was updated to use taskqueue_enqueue_timeout() instead of
scheduling a callout to do the taskqueue_enqueue(). There is also now a
comment explaining that insertion-debounce is what's going on -- it took me
a long time to realize that's what the old sdhci_card_delay() routine was
really doing. There is no functional difference between the old and new
debounce code (I hope!).
Use device-specific Rx buffer size to ensure that data will not be
truncated + add a warning if truncation was detected (the driver
cannot handle this case correctly yet).
Tested with:
- RTL8188CUS, RTL8188EU and RTL8821AU, STA / AP modes.
There are places where checks are made against VM_MAX_KERNEL_ADDRESS, or
virtual_end (set to VM_MAX_KERNEL_ADDRESS). With 32-bit checks, an address will
always be less than or equal to 0xffffffff. Drop a page, so those checks can
terminate loops safely.
With clang 4.0.0, I'm getting the following warnings:

This function is used only by ipsec_getpolicybysock() to fill security
policy index selector for locally generated packets (that have INPCB).
The function incorrectly assumes that spidx is the same for both directions.
Fix this by using new direction argument to specify correct INPCB security
policy - sp_in or sp_out. There is no need to fill both policy indeces,
because they are overwritten for each packet.
This fixes security policy matching for outbound packets when user has
specified TCP/UDP ports in the security policy upperspec.

This is a skeleton set based on ieee80211_ht.c. It implements some IE
parsing, some basic unfinished negotiation, and channel promotion/demotion.
However, by itself it's not enough to do VHT - notably, the actual
channel promotion for STA mode at least is done in ieee80211_ht.c as
part of htinfo_update_chw(). I was .. quite amused when I found that
out.
I'm checking this in so others can see progress rather than one huge
commit when VHT is "done" (which will likely be quite a while.)
Many embedded SoC controllers that are (more or less) sdhci-compatible don't
implement card detect, and the related values in the PRESENT_STATE register
aren't useful. A bridge driver can now implement get_card_present() to read
a gpio pin or whatever else is necessary for that system.
The default implementation reads the CARD_PRESENT bit from the PRESENT_STATE
register, so existing drivers will keep working (or keep not-fully-working,
since many drivers right now can't detect card insert/remove).
sched_*(2) syscalls might be not available at runtime. Defining this
constant as zero directs POSIX-compliant code to call sysconf(3) to
detect the feature at runtime, and forces libc sysconf(3) to ask
kernel.

* Add the VHT capability element to the driver capabilities so ifconfig
can see if VHT is available
* Add ioctl plumbing for enabling/disabling VHT and each of the VHT
widths.
Note: this DOES change the ABI (the driver caps ioctl struct size, sigh)
so this will require a recompile of at least ifconfig.
In preparation for VHT station support, we need to store VHT IEs when
scanning so we can choose to upgrade to VHT.
This doesn't change the ABI - it just steals spare[] entries.
The VHT operational element (VHTOPMODE) isn't a uint32_t - it's
the MCS sets, freq1/freq2 parameters and channel width.
So, store the channel width too in lieu of just storing the
IE struct.
This changes the VHT parameter layout in ieee80211_node but it
doesn't change ABI at all.
The 11n code uses these bits for both configuration /and/ controlling
the channel width on softmac chips - it uses it to find the widest
width for all VAPs (eg a HT20 vap and a HT40 vap) to know what to
configure the ic_curchan.
For fullmac devices it isn't /as/ important, as each virtual device
exposed by the firmware will likely have its own configuration and the
firmware figures out what to do to enable it.
These came from Linux mac80211 headers and are configuration bits, not
VHTOPMODE field parameters.
Whilst here, add the field names for the VHTCAP bits.
Tested:
* ath10k, 11ac STA mode
Add a MSG_MOREOTOCOME message flag. When this flag is set, sosend*

sys/ptrace.h includes sys/signal.h, which includes sys/_sigset.h.
Note that sys/_sigset.h only defines osigset_t if COMPAT_43 was defined.
Two lines later, sys/ptrace.h includes machine/reg.h, which in case of
powerpc, includes opt_compat.h.
After the include headers reordering in r311345, we have sys/ptrace.h
included before sys/sysproto.h.
If COMPAT_43 was requested in the kernel config, the result is that
sys/_sigset.h does not define osigset_t, but sys/sysproto.h sees
COMPAT_43 and uses osigset_t.
Fix this by explicitely including opt_compat.h to cover the whole
kern/kern_exec.c scope.
