KVM: Fix fs/gs reload oops with invalid ldt

kvm reloads the host's fs and gs blindly, however the underlying segment
descriptors may be invalid due to the user modifying the ldt after loading
them.

Fix by using the safe accessors (loadsegment() and load_gs_index()) instead
of home grown unsafe versions.

[ARM] tegra: Set bit 22 in the PL310 AuxCtrl

Duplicate Catalin Marinas' <catalin.marinas@arm.com> ARM change
6395/1 for VExpress to tegra

Clearing bit 22 in the PL310 Auxiliary Control register (shared
attribute override enable) has the side effect of transforming Normal
Shared Non-cacheable reads into Cacheable no-allocate reads.

Coherent DMA buffers in Linux always have a Cacheable alias via the
kernel linear mapping and the processor can speculatively load cache
lines into the PL310 controller. With bit 22 cleared, Non-cacheable
reads would unexpectedly hit such cache lines leading to buffer
corruption.

13 years ago[ARM/tegra] dma: add transfer count query. Checking interrupt pending status.
Jay Cheng [Sat, 16 Oct 2010 03:55:02 +0000 (23:55 -0400)]
[ARM/tegra] dma: add transfer count query. Checking interrupt pending status.
 Stopping Dma after last req transfer.

add an API to return the completed transfer count of a pending, active
or finished DMA request

originally fixed by Gary King <gking@nvidia.com>

It is observed that the dma interrupt has the lower priority then
its client interupt priority. When client's isr calls dma get transfer,
the dma status has not been upated as dma isr have not been served yet.
So before reading the status, explicitly checking the interrupt status and
handling accordingly.

The another issue which is observed is that if dma has transferred the data
of amount = requested -4 and if it moves to invalid requestor before stopping
then status got reset and tarnsfered bytes becomes 0. This seems the apb dma
hw behavior. Following is the suggestion to overcome this issue:
- Disable global enable bit.
- Read status.
- Stop dma.
- Enable global status bit.

Added this workaround and it worked fine.

originally fixed by Laxman Dewangan <ldewangan@nvidia.com>

In continous mode, dma should stop after last transfer completed and
if there is no more req pending.
If there is pending req then it should check whether it has updated
in hw for next transfer or not and if it has not started then stop dma
and start new req immediatley.
