commit 4ce78a838c (can: c_can: Speed up rx_poll function) hyped a
performance improvement by reducing the access to the interrupt
pending register from a dual 16 bit to a single 16 bit access. Wow!
Thereby it crippled the driver to cast the 16 msg objects in stone,
which is completly braindead as
The function is broken in several ways:
- The function does not wait for the init to complete.
That can take quite some microseconds.
- No protection against being called for two chips at the same
time. SMP is such a new thing, right?
Clear the start and the init done bit
First of all, I'm really grumpy as hell.
This is the worst driver I looked at in the last 10 years. And that's
an achievement.
The driver is full of serious bugs:
- Two HW init routines are not spec compliant.
- Completely defective message buffer handling in several ways
That
According to the documentation the CPU must wait for CONTROL_INIT to
be cleared before writing to the baudrate registers.

This reverts commit 56dd669a138c, which makes the GART visible in
/proc/iomem. This fixes a regression: e501b3d87f00 ("agp: Support 64-bit

hi,
this patchset moves thread's map_groups to be dynamically
allocated and shared within process threads.
The main benefit would be to be able to look up memory
map from any thread that belongs to the process.
This implements one of the solution ideas for issue
described by Don in following

The TP_printk() should never dereference any pointers, because the ring
buffer can be read at some unknown time in the future. If a device no
longer exists, it can cause a kernel oops. This also makes this
event useless when saving the ring buffer in userspaces tools such as

Add keyscan support for stih416.
It is disabled by default given that it is not enabled on all boards.

Changes in v2:
- use standard format for matrix keymap
- suppress __exit mark for keyscan_remove()
- Call to keyscan_stop() shoudl go into keyscan_close() implementation
- use of SIMPLE_DEV_PM_OPS()
- rename compatibility name into "st,sti-keyscan"
- suppress platform data management
- omit vendor
This patch adds ST Keyscan driver to use the keypad hw a subset
of ST boards provide. Specific board setup will be put in the
given dt.

We will reuse it to process a nonzero IRR that is passed to KVM_SET_IRQCHIP.

Commonize the handling of masking, which was absent for kvm_ioapic_set_irq.
Setting remote_irr does not need a separate function either, and merging
the two functions avoids confusion.

I have applied the platform removal patch with the Ack
from Kevin and Sekhar. Please apply these other patches
through the input/mfd/spi trees.
Arnd Bergmann (3):
spi: remove obsolete spi-ti-ssp driver
mfd: remove obsolete ti-ssp driver
input: remove obsolete tnetv107x drivers
The tnetv107x platform is getting removed, so the touchscreen
and keypad drivers for this platform will no longer be needed
either.

Unlike the old qemu-kvm, which really never did that, with new QEMU
it is for some reason somewhat likely to migrate a VM with a nonzero
IRR in the ioapic. In the case of ISA edge-triggered interrupts,
this represents an interrupt that has not left the IOAPIC, which would
be okay but it is not
This ensures that IRR bits are set in the KVM_GET_IRQCHIP result only if
the interrupt is still sitting in the IOAPIC. After the next patches, it
avoids spurious reinjection of the interrupt when KVM_SET_IRQCHIP is
called.

After the previous patches, an interrupt whose bit is set in the IRR
register will never be in the LAPIC's IRR and has never been injected
on the migration source. So inject it on the destination.
This fixes migration of Windows guests without HPET (they use the RTC
to trigger the scheduler
