For OUT endpoints, zero-length transfers require MaxPacketSize buffer as
per the DWC_usb3 programming guide 3.30a section 4.2.3.3.
This patch fixes this by explicitly checking zero length
transfer to correctly pad up to MaxPacketSize.

Add a helper functions to check video modes. Also add a helper to check
framebuffer buffer objects, using the former for consistency. That way
we should not fail in qxl_primary_atomic_check() because video modes
which are too big will not be added to the mode list in the first place.

Generic fbdev emulation needs this. Also: We must keep track of the
number of mappings now, so we don't unmap early in case two users want a
kmap of the same bo. Add a sanity check to destroy callback to make
sure kmap/kunmap is balanced.

qdev->monitors_config->max_allowed is effectively set by the
qxl.num_heads module parameter, stored in the qxl_num_crtc variable.
Lets get rid of the indirection and use the variable qxl_num_crtc
directly. The kernel doesn't need to dereference pointers each time it
needs the value, and when reading the code you don't have to trace where
and why qdev->monitors_config->max_allowed is set.

The qxl device supports only a single active framebuffer ("primary
surface" in spice terminology). In multihead configurations are handled
by defining rectangles within the primary surface for each head/crtc.
Userspace which uses the qxl ioctl interface (xorg qxl driver) is aware
of this limitation and will setup framebuffers and crtcs accordingly.
Userspace which uses dumb framebuffers (xorg modesetting driver,
wayland) is not aware of this limitation and tries to use two
framebuffers (one for each crtc) instead.
The qxl kms driver already has the dumb bo separated from the primary
surface, by using a (shared) shadow bo as primary surface. This is
needed to support pageflips without having to re-create the primary
surface. The qxl driver will blit from the dumb bo to the shadow bo
instead.
So we can extend the shadow logic: Maintain a global shadow bo (aka
primary surface), make it big enough that dumb bo's for all crtcs fit in
side-by-side. Adjust the pageflip blits to place the heads next to each
other in the shadow.
With this patch in place multihead qxl works with wayland.

Pass the shadow bo to qxl_io_create_primary() instead of expecting
qxl_io_create_primary to check bo->shadow. Set is_primary flag on the
shadow bo. Move the is_primary tracking into qxl_io_create_primary()
and qxl_io_destroy_primary() functions.
That simplifies primary surface tracking and the workflow in
qxl_primary_atomic_update().

Track which bo is used as primary surface. With that in place we don't

The qxl device ties the cursor to the primary surface. Therefore
calling qxl_io_destroy_primary() and qxl_io_create_primary() to switch
the framebuffer causes the cursor information being lost and the driver
must re-apply it.
The correct call order to do that is qxl_io_destroy_primary() +
qxl_io_create_primary() + qxl_primary_apply_cursor().
The old code did qxl_io_destroy_primary() + qxl_primary_apply_cursor() +
qxl_io_create_primary(). Due to qxl_primary_apply_cursor request being
queued in a ringbuffer and qxl_io_create_primary() trapping to the
hypervisor instantly there is a high chance that qxl_io_create_primary()
is processed first even with the wrong call order. But it's racy and
thus not reliable.

When we check the tcp options of a packet and it doesn't match the current
fingerprint, the tcp packet option pointer must be restored to its initial
value in order to do the proper tcp options check for the next fingerprint.
Here we can see an example.
Assumming the following fingerprint base with two lines:
S10:64:1:60:M*,S,T,N,W6: Linux:3.0::Linux 3.0
S20:64:1:60:M*,S,T,N,W7: Linux:4.19:arch:Linux 4.1
Where TCP options are the last field in the OS signature, all of them overlap
except by the last one, ie. 'W6' versus 'W7'.
In case a packet for Linux 4.19 kicks in, the osf finds no matching because the
TCP options pointer is updated after checking for the TCP options in the first
line.
Therefore, reset pointer back to where it should be.

During igt, we ask to reset the device if any requests are still
outstanding at the end of a test, as this quickly kills off any
erroneous hanging request streams that may escape a test. However, since
it may take the device a few milliseconds to flush itself after the end
of a normal test, *cough* guc *cough*, we may accidentally tell the
device to reset itself after it idles. If we wait a moment, our usual
I915_IDLE_ENGINES_TIMEOUT of 200ms (seems a bit high, but still better
than umpteen hangchecks!), we can differentiate better between a stuck
engine and a healthy one, and so avoid prematurely forcing the reset and
any extra complications that may entail.

When the MC route socket is closed, mroute_clean_tables() is called to
cleanup existing routes. Mistakenly notifiers call was put on the cleanup
of the unresolved MC route entries cache.
In a case where the MC socket closes before an unresolved route expires,
the notifier call leads to a crash, caused by the driver trying to
increment a non initialized refcount_t object [1] and then when handling
is done, to decrement it [2]. This was detected by a test recently added in
commit 6d4efada3b82 ("selftests: forwarding: Add multicast routing test").
Fix that by putting notifiers call on the resolved entries traversal,
instead of on the unresolved entries traversal.

Digging through the ioctls with Al because of the previous
patches, we found that on 64-bit decnet's dn_dev_ioctl()
is wrong, because struct ifreq::ifr_ifru is actually 24
bytes (not 16 as expected from struct sockaddr) due to the
ifru_map and ifru_settings members.
Clearly, decnet expects the ioctl to be called with a struct
like
struct ifreq_dn {
char ifr_name[IFNAMSIZ];
struct sockaddr_dn ifr_addr;
};
since it does
struct ifreq *ifr = ...;
struct sockaddr_dn *sdn = (struct sockaddr_dn *)&ifr->ifr_addr;
This means that DN_IFREQ_SIZE is too big for what it wants on
64-bit, as it is
sizeof(struct ifreq) - sizeof(struct sockaddr) +
sizeof(struct sockaddr_dn)
This assumes that sizeof(struct sockaddr) is the size of ifr_ifru
but that isn't true.
Fix this to use offsetof(struct ifreq, ifr_ifru).
This indeed doesn't really matter much - the result is that we
copy in/out 8 bytes more than we should on 64-bit platforms. In
case the "struct ifreq_dn" lands just on the end of a page though
it might lead to faults.
As far as I can tell, it has been like this forever, so it seems
very likely that nobody cares.

Pull x86 fixes from Thomas Gleixner:
"A set of fixes for x86:
- Fix the swapped outb() parameters in the KASLR code
- Fix the PKEY handling at fork which missed to preserve the pkey
state for the child. Comes with a test case to validate that.
- Fix the entry stack handling for XEN PV to respect that XEN PV
systems enter the function already on the current thread stack and
not on the trampoline.
- Fix kexec load failure caused by using a stale value when the
kexec_buf structure is reused for subsequent allocations.
- Fix a bogus sizeof() in the memory encryption code
- Enforce PCI dependency for the Intel Low Power Subsystem
- Enforce PCI_LOCKLESS_CONFIG when PCI is enabled"

Pull x86 timer fixes from Thomas Gleixner:
"Two commits which were missed to be sent during the merge window.
- The TSC calibration fix turns out to be more urgent as recent
Skylake-X systems seem to have massive trouble with calibration
disturbance. This should go back into stable for that reason and it
the risk of breakage is rather low.
- Drop an unused define"

Pull timer fix from Thomas Glexiner:
"A single regression fix to address the unintended breakage of posix
cpu timers.
This is caused by a new sanity check in the common code, which fails
for posix cpu timers under certain conditions because the posix cpu
timer code never updates the variable which is checked"

in the comment but missing in the code

Before assigning window data, we should check if the yuv2yuv vop-data
is set at all, because it looks like it can otherwise reference something
wrong, as I saw on my rk3188 today which ended up in a null pointer
dereference in vop_plane_atomic_update when accessing the yuv2yuv data.

Pull irq fixes from Thomas Gleixner:
"A small set of fixes for the interrupt subsystem:
- Fix a double increment in the irq descriptor allocator which
resulted in a sanity check only being done for every second
affinity mask
- Add a missing device tree translation in the stm32-exti driver.
Without that the interrupt association is completely wrong.
- Initialize the mutex in the GIC-V3 MBI driver
- Fix the alignment for aliasing devices in the GIC-V3-ITS driver so
multi MSI allocations work correctly
- Ensure that the initial affinity of a interrupt is not empty at
startup time.
- Drop bogus include in the madera irq chip driver
- Fix KernelDoc regression"
