Following the guidelines it takes 3 seconds to perform an FLR
reset. Let's give it a bit more slack because this time can
change depending on the platform and on the firmware

The whole point of the previous fixes has been to change the CCS
hardware configuration to generate only one stream available to
the compute users. We did this by changing the info.engine_mask
that is set during device probe, reset during the detection of
the fused engines, and finally reset again

Based on a test case developed by Lionel Landwerlin, this exercises
creation of partial mmaps using both direct methods of a partial mmap()
(where the mmap() only covers a portion of the object) and
munmap() to do the same.

I thought I had cleaned up the 'gem/' directory in the past, but

the problem is that we cannot apply the workaround without
reserving one page from the GTT total size and we need to apply
the workaround.

# v5.4+
this tag list is a bit confusing. Let's keep all Cc's together

No need to resend also because I retriggered another round of

engines. Wa_14019159160 recommends disabling it across all

Userspace, though, needs to know the full address range.

In anticipation of the upcoming commit that will operate with
only one CCS stream, when more than one CCS slice is present,
create a new for_each_available_engine() that excludes CCS
engines beyond the forst. Begin using it in the hangcheck
selftest.
