Hello Rafael, Viresh,

This series contains three fixes for the amd-pstate driver for 6.11.
Could you please include it in your tree?

These patches are based on linux-pm/master with the top commit
7c626ce4bae1 ("Linux 6.11-rc3").

There are three patches,

1. To fix an uninitialized variable in amd_pstate_cpu_boost_update()
   from Dan Carpenter:
   https://lore.kernel.org/lkml/7ff53543-6c04-48a0-8d99-7dc010b93b3a@stanley.mountain/

2. Use topology_logical_package_id() instead of
   topology_logical_die_id() definition of the later function has
   changed on some AMD processors since the inclusion of the CPUID
   0x80000026 parser:
   https://lore.kernel.org/lkml/20240801124509.3650-1-Dhananjay.Ugwekar@amd.com/

3. Remove a warning for the absence fo X86_FEATURE_CPPC on Zen1 and
   Zen2 since they don't have the feature defined. This fixes the
   regression reported by David Wang:
   https://lore.kernel.org/lkml/20240730140111.4491-1-00107082@163.com/

Thanks and Regards
gautham.

Thanks for handling these.  I'm back now, I'm digging through my inbox.
Assuming Rafael didn't already pull these I'll batch these into my 
amd-pstate branch for the robots to bang on and then send a PR after I 
go through everything else that happened.

Thank you Mario. I will be sending an updated version to Patch 3
"Remove warning for X86_FEATURE_CPPC on Zen1 and Zen2" to incorporate
feedback from Xiaojian.

Please merge the Patches 1 and 2 from this series.
