Hi Paolo and Radim,
Here's the first round of fixes for KVM/ARM for v4.15. This is a fairly large
set of fixes, partially because we spotted a handful of issues from running the
SMATCH static analysis on the code (thanks to AKASHI Takahiro).
In more details, this pull request fixes:
- A number of issues in the vgic discovered using SMATCH
- A bit one-off calculation in out stage base address mask (32-bit and
64-bit)
- Fixes to single-step debugging instructions that trap for other
reasons such as MMMIO aborts
- Printing unavailable hyp mode as error
- Potential spinlock deadlock in the vgic
- Avoid calling vgic vcpu free more than once
- Broken bit calculation for big endian systems
The following changes since commit 4fbd8d194f06c8a3fd2af1ce560ddb31f7ec8323:
