Merge tag 'misc-habanalabs-fixes-2021-01-13' of https://git.kernel.org/pub/scm/linux/kernel/git/ogabbay/linux into char-misc-linus
Oded writes:
This tag contains the following bug fixes:
- Fix the dma address that is passed to dma_mmap_coherent. We passed
an address that includes an offset that is needed by our device and
that caused dma_mmap_coherent to do an errounous mapping.
- Fix the reset process in case failures happen during the reset process.
Without this fix, if the user would have asked to perform reset after
the previous reset failed he would get a kernel panic
- WA to prevent soft lockup BUG during unmap of host memory. In case of
tens of thousands of mappings, the unmapping can take a long time that
exceeds the soft lockup timeout. This WA adds a small sleep every 32K
page unmappings to prevent that.
