This patch allows the user to modify the TPC PLL clock relaxation value
on-the-fly in order to reduce power consumption.
To enable this, the patch removes the protection from the specific
register that controls this behavior.

Hard-reset of our device should never fail, due to dangers of permanent

This patch refactors the code that is responsible to set the DMA mask for
the device.
Upon each change of the dma mask, the driver will save the new value that
was set. This is needed in order to make sure we don't try to increase the
mask a second time, in case we failed in the first time. This is
especially relevant for Power machines, as that may cause a change in
configuration of the TVT which will break the device.
Goya will first try to set the device's dma mask to 39 bits, so that the
memory that is allocated on the host machine for communication with the
device's cpu will be in a bus address which is lower then 39 bits. Later,
Goya will try to increase that mask to 48 bits, but only if setting the
mask to 39 bits was successful.

This patch adds shadow mapping to the MMU module. The shadow mapping
allows traversing the page table in host memory rather reading each PTE
from the device memory.
It brings better performance and avoids reading from invalid device
address upon PCI errors.
Only at the end of map/unmap flow, writings to the device are performed in
order to sync the H/W page tables with the shadow ones.

At the start of some IOCTLs we check if the device is disabled or in reset.
If it is, we return -EBUSY and print a message to kernel log.
Because these IOCTLs can be called at very high frequency, use ratelimit
to avoid spamming the kernel log. Also use the same type of message -
dev_warn - in all the relevant IOCTLs.

If userspace doesn't end the input with a newline (which can easily
happen if the write happens from a C program that does write(fd,
iface, strlen(iface))), we may end up including garbage from a
previous, longer value in the device_name. For example
# cat device_name
# printf 'eth12' > device_name
# cat device_name
eth12
# printf 'eth3' > device_name
# cat device_name
eth32
I highly doubt anybody is relying on this behaviour, so switch to
simply copying the bytes (we've already checked that size is <
IFNAMSIZ) and unconditionally zero-terminate it; of course, we also
still have to strip a trailing newline.
This is also preparation for future patches.

remained undiscovered for quite some time.
- Fix wrong warning messages that the IOMMU core code prints

domain types (like Intel VT-d).

Here are some binder, habanalabs, and vboxguest driver fixes for
5.1-rc3.
The Binder fixes resolve some reported issues found by testing, first by
the selinux developers, and then earlier today by syzbot.
The habanalabs fixes are all minor, resolving a number of tiny things.
The vboxguest patches are a bit larger. They resolve the fact that
virtual box decided to change their api in their latest release in a way
that broke the existing kernel code, despite saying that they were never
going to do that. So this is a bit of a "new feature", but is good to
get merged so that 5.1 will work with the latest release. The changes
are not large and of course virtual box "swears" they will not break
this again, but no one is holding their breath here.
All of these have been in linux-next for a while with no reported

The important fixes at this time are a couple fixes in ALSA core:
a fix for PCM is about the OOB access in PCM OSS plugins that has
been for long time, but hasn't hit so often until now just because
we allocated a large buffer via vmalloc(), and surfaced more often
after switching to kvmalloc(). Another fix is for a long-standing
PCM problem wrt racy PM resume. Others are trivial nospec coverage
and usual HD-audio quirks.
