When dwc3 core enters into suspend mode, the system (especially for mobile

Introduce an attribute "inquiry_string" to the lun.
In some environments, e. g. BIOS boot menus, the inquiry string
is the only information about devices presented to the user. The
default string depends on the "cdrom" bit of the first lun as
well as the kernel version and allows no further customization.
So without access to the client it is not obvious which gadget is
active at a given point and what any of the available luns might
contain.
If "inquiry_string" is ignored or set to the empty string, the
old behavior is preserved.

speed dropped to 150 Mbit/s compared to 900 Mbit/s with NCM
gadget. Problem seems to be that net2280/USB3380 has only four
DMA channels and those DMA channels are allocated to first HW

In the gpio based case, the status of the phy is known at start by
reading the VBus gpio.
Actually, this is a fix, as this initial state, when not set up,
prevents a gadget to answer to the enumeration phase, as there is no
notification in this case (the VBus is already high when kernel boots)
so no interrupt is triggered, and the flow is :
- gadget initializes
- gadget gets its phy-generic with a xxx_get_phy_xxx() call type
- gadget does a "set_peripheral()" call type
=> here if the otg->state is correctly filled, the proper vbus
handling will be called, and the gadget will be aware it should
answer enumeration and go forth
Without this fix, the USB cable must be removed and replugged for any
gadget relying on phy-generic and its gpio vbus handling to work.
The problem was seen on a pxa27x architecture based board on a
devicetree build.

In the legacy behavior, and USB phy, upon detection a VBus signal, was
calling usb_gadget_vbus_(dis)connect().
This model doesn't work if the phy is generic and doesn't have an
adherence to the gadget API.
Instead of relying on the phy to call the gadget API, hook up the phy
notifier to report the VBus event, and upon it call the usb gadget API
ourselves.
This brings a new ordering problem, as before even if the usb_get_phy()
was failing because the UDC was probed before the phy, the phy would
call the gadget anyway, making the VBus connection event forwarded to
the gadget. Now we rely on the notifier, we have to ensure the
xxx_get_phy() does indeed work.
In order to cope with this, it is assumed that :
- for legacy platform_data machine, as the ordering cannot be ensured,
the phy must call usb_gadget_vbus_(dis)connect, such as
phy-gpio-vbus-usb.c
- for new devicetree platforms, we'll rely on the probe deferral, and
the phy can be gadget API agnostic.

This is an entirely new driver instead of yet another set of patches

1) Mapping from PCI devices to socket/memory controller is significantly
different. Skylake scatters devices on a socket across a number of

2) There is an extra level of interleaving via the "mcroute" register
that would be a little messy to squeeze into the old driver.

When building gccgo in userspace, errno.h gets parsed and the go include file
sysinfo.go is generated.
Since EREFUSED is defined to the same value as ECONNREFUSED, and ECONNREFUSED
is defined later on in errno.h, this leads to go complaining that EREFUSED
isn't defined yet.
Fix this trivial problem by moving the define of EREFUSED down after
ECONNREFUSED in errno.h (and clean up the indenting while touching this line).

The kernel test robot reported a usercopy failure in the new hardened
sanity checks, due to a page-crossing copy of the FPU state into the
task structure.
This happened because the kernel test robot was testing with SLOB, which
doesn't actually do the required book-keeping for slab allocations, and
as a result the hardening code didn't realize that the task struct
allocation was one single allocation - and the sanity checks fail.
Since SLOB doesn't even claim to support hardening (and you really
shouldn't use it), the straightforward solution is to just make the
usercopy hardening code depend on the allocator supporting it.
