perf tools changes for 5.18: 2nd batch

Browse Source 
- Avoid SEGV if core.cpus isn't set in 'perf stat'.
 
 - Stop depending on .git files for building PERF-VERSION-FILE, used in
   'perf --version', fixing some perf tools build scenarios.
 
 - Convert tracepoint.py example to python3.
 
 - Update UAPI header copies from the kernel sources:
 
     socket, mman-common, msr-index, KVM, i915 and cpufeatures.
 
 - Update copy of libbpf's hashmap.c.
 
 - Directly return instead of using local ret variable in
   evlist__create_syswide_maps(), found by coccinelle.

*
* The (page-aligned) allocated size for the object will be returned.
*
* Note that for some devices we have might have further minimum
* page-size restrictions(larger than 4K), like for device local-memory.
* However in general the final size here should always reflect any
* rounding up, if for example using the I915_GEM_CREATE_EXT_MEMORY_REGIONS
* extension to place the object in device local-memory.
*
* DG2 64K min page size implications:
*
* On discrete platforms, starting from DG2, we have to contend with GTT
* page size restrictions when dealing with I915_MEMORY_CLASS_DEVICE
* objects. Specifically the hardware only supports 64K or larger GTT
* page sizes for such memory. The kernel will already ensure that all
* I915_MEMORY_CLASS_DEVICE memory is allocated using 64K or larger page
* sizes underneath.
*
* Note that the returned size here will always reflect any required
* rounding up done by the kernel, i.e 4K will now become 64K on devices
* such as DG2.
*
* Special DG2 GTT address alignment requirement:
*
* The GTT alignment will also need to be at least 2M for such objects.
*
* Note that due to how the hardware implements 64K GTT page support, we
* have some further complications:
*
* 1) The entire PDE (which covers a 2MB virtual address range), must
* contain only 64K PTEs, i.e mixing 4K and 64K PTEs in the same
* PDE is forbidden by the hardware.
*
* 2) We still need to support 4K PTEs for I915_MEMORY_CLASS_SYSTEM
* objects.
*
* To keep things simple for userland, we mandate that any GTT mappings
* must be aligned to and rounded up to 2MB. The kernel will internally
* pad them out to the next 2MB boundary. As this only wastes virtual
* address space and avoids userland having to copy any needlessly
* complicated PDE sharing scheme (coloring) and only affects DG2, this
* is deemed to be a good compromise.
