Commit f599c64fdf7d ("xen-netfront: Fix race between device setup and

happens before we do register_netdev() so using netdev->name in
xennet_init_queue() is incorrect, we end up with the following in
/proc/interrupts:
60: 139 0 xen-dyn -event eth%d-q0-tx
61: 265 0 xen-dyn -event eth%d-q0-rx
62: 234 0 xen-dyn -event eth%d-q1-tx
63: 1 0 xen-dyn -event eth%d-q1-rx
and this looks ugly. Actually, using early netdev name (even when it's
already set) is also not ideal: nowadays we tend to rename eth devices
and queue name may end up not corresponding to the netdev name.
Use nodename from xenbus device for queue naming: this can't change in VM's
lifetime. Now /proc/interrupts looks like
62: 202 0 xen-dyn -event device/vif/0-q0-tx

datacopy path from zerocopy, and do only batching for datacopy. This
is because zercopy had already supported its own batching.

There are a couple of places in the x86 EFI stub code where we select
between 32-bit and 64-bit versions of the support routines based on
the value of efi_early->is64. Referencing that field directly is a
bad idea, since it prevents the compiler from inferring that this
field can never be true on a 32-bit build, and can only become false
on a 64-bit build if support for mixed mode is compiled in. This
results in dead code to be retained in the uncompressed part of the
kernel image, which is wasteful.
So switch to the efi_is_64bit() helper, which will resolve to a
constant boolean unless building for 64-bit with mixed mode support.

The UGA draw protocol discovery routine looks for a EFI handle that has
both the UGA draw protocol and the PCI I/O protocol installed. It checks
for the latter by calling handle_protocol() and pass it a PCI I/O
protocol pointer variable by reference, but fails to initialize it to
NULL, which means the non-NULL check later on in the code could produce
false positives, given that the return code of the handle_protocol() call
is ignored entirely. So add the missing initialization.

The two versions of setup_uga##() are mostly identical, with the
exception of the size of EFI_HANDLE. So let's merge the two, and
pull the implementation into the calling function setup_uga().
Note that the 32-bit version was only mixed-mode safe by accident:
it only calls the get_mode() method of the UGA draw protocol, which
happens to be the first member, and so truncating the 64-bit void* at
offset 0 to 32 bits happens to produce the correct value. But let's
not rely on that, and use the proper API instead.

The UEFI spec does not permit runtime services to be called
reentrantly, and so it is up to the OS to provide proper locking
around such calls.
For the native case, this was fixed a long time ago, but for the
mixed mode case, no locking is done whatsoever. Note that the calls
are made with preemption and interrupts disabled, so only SMP
configurations are affected by this issue.
So add a spinlock and grab it when invoking a UEFI runtime service
in mixed mode. We will also need to provide non-blocking versions
of SetVariable() and QueryVariableInfo(), so add those as well.

free_irq() waits until all handlers for this IRQ have completed. As the

Also first free the irq (or stop the worker respectively) such that
mv88e6xxx_g1_irq_thread_work() isn't called any more before the irq

"imply HWMON" was supposed to ensure that the SFP phy code can be built
with HWMON enabled or disabled while at the same time ensuring that
HWMON is not built as module if SFP is built into the kernel.
Unfortunately, that does not work as intended. With "allmodconfig", it
results in several unrelated HWMON drivers to be disabled instead of
being built as module as expected.
Let's use the old "depends on HWMON || HWMON=n" instead. This is slightly
different (it enforces SFP to be built as module if HWMON is built as
module), but it is better than the alternative of using "IS_REACHABLE()"
in the driver since that would disable sensor support if HWMON is built
as module and SFP is built into the kernel.

Pull ARM SoC fixes from Olof Johansson:
- Fix interrupt type on ethernet switch for i.MX-based RDU2
- GPC on i.MX exposed too large a register window which resulted in
userspace being able to crash the machine.

droid4.
