Fix copy/paste mistake in kvm_getswapinfo(3) It seems this manpage was copied from kvm_getloadavg(3), but the DIAGNOSTICS section was not updated completely. Update the section with correct information about a return value of -1.

MFC r361977: libusb: improve compatibility

2020-06-16T12:21:55Z

Specifically, add LIBUSB_CLASS_PHYSICAL and the libusb_has_capability API. Descriptions and functionality for these derived from the documentation at [0]. The current set of capabilities are all supported by libusb. These were detected as missing after updating net/freerdp to 2.1.1, which attempted to use both. [0] http://libusb.sourceforge.net/api-1.0/group__libusb__misc.html

Adapt merge of r361581 to 9-stable to unbreak kernel compilation.

USB HID descriptors may push/pop the current state to allow description of items residing in a so-called union. FreeBSD currently only supports 4 such push levels. If the push level is not restored within the processing of the same HID item, an invalid memory location may be used for subsequent HID item processing. Verify that the push level is always valid when processing HID items. Reported by: Andy Nguyen (Google) Sponsored by: Mellanox Technologies

Assign process group of the TTY under the "proctree_lock". This fixes a race where concurrent calls to doenterpgrp() and leavepgrp() while TIOCSCTTY is executing may result in tp->t_pgrp changing value so that tty_rel_pgrp() misses clearing it to NULL. For more details refer to the use of pgdelete() in the kernel. No functional change intended.

Set the maximum exit latency to 0 for XHCI USB 3.0 devices, because we don't implement link power management, LPM. This fixes error code XHCI_TRB_ERROR_BANDWIDTH for isochronous USB 3.0 transactions. Submitted by: Horse Ma Sponsored by: Mellanox Technologies
