Hi Michal:
We need a API to tell TTM module the system totally has how many swap cache.
Then TTM module can use it to restrict how many the swap cache it can use to

For Now we set the threshold of swap size TTM used as 1/2 * total size and
leave the rest for others use.
Both IRQCHIP_SKIP_SET_WAKE and .irq_set_wake() is

Add a lock to vop to avoid disabling the crtc while waiting for a line
flag while enabling psr. If we disable in the middle of waiting for the
line flag, we'll end up timing out or worse.

The PB520 and PB540 have a flawed early-revision 68LC040 processor* which

When mapping external DMA-bufs through the PRIME mmap call, we might be
given an offset which has to be respected. However for the internal DRM
GEM mmap path, we have to ignore the fake mmap offset used to identify
the buffer only. Curre

The prime fd to handle ioctl was not used with rockchip before. Support

Hi, Rafael
Could you please help to review this patch? This is a small change to
add ACPI_SIG_IORT to table_sigs[].
Loading IORT table from initrd is very useful to debug SMMU node/device
probe, MSI allocation, stream id translation and verifying IORT table
from firmware. So, I add this.
Thanks

Quoting Linus:
I do think that it would be a good idea to very expressly document
the fact that it's not that the user access itself is unsafe. I do
agree that things like "get_user()" want to be protected, but not
because of any direct bugs or problems with get_user() and friends,
Eduardo,
This is why it would be good to have a CPUID bit that says: "apply SkyLake RSB
stuffing." That's preferable to "trust FMS" for VMware.
If Intel defines such a feature flag, sets it on SkyLake, and Linux uses it...
that would be very helpful for VMware.
I won't speak for GCE and AWS.
In preparation for converting some __uaccess_begin() instances to
__uacess_begin_nospec(), make sure all 'from user' uaccess paths are
using the _begin(), _end() helpers rather than open-coded stac() and
clac().
There are no functional changes in this patch.
