      !85 [OLK-5.10] x86/cpufeatures: Add Zhaoxin feature bits · ef16aa34
      由 openeuler-ci-bot 提交于 
      Merge Pull Request from: @leoliu-oc 
 
The patch is to add Zhaoxin feature bits on Zhaoxin CPUs.

### Issue
[#I5NYQF](https://gitee.com/openeuler/kernel/issues/I5NYQF)

### Test
Build and boot kernel with this patch. Check various features in `lscpu` or `/proc/cpuinfo`.
```shell
# cat /proc/cpuinfo | grep flags
# or
# lscpu | grep flags
# you will see new Zhaoxin feature flags
# for example, rng2/rng2_en/phe2/phe2_en/...
# +#define X86_FEATURE_RNG2		(5*32+22) /* 2nd generation of RNG present */
# +#define X86_FEATURE_RNG2_EN    (5*32+23) /* 2nd generation of RNG enabled */
# +#define X86_FEATURE_PHE2		(5*32+25) /* SHA384 and SHA 512 present */
# +#define X86_FEATURE_PHE2_EN    (5*32+26) /* SHA384 and SHA 512 enabled */

[Description]​
https://gitee.com/openeuler/intel-kernel/issues/I5V3SJ

An HBM memory channel is divided into two pseudo channels. Each
pseudo channel has its own retry_rd_err_log registers. Retrieve and
print retry_rd_err_log registers of the HBM pseudo channel if the
memory error is from HBM.

      !210 x86/tsc: use topology_max_packages() in tsc watchdog check · 425c0a7b

[Description]​
Temporary fix for #I5U037

Occasionally TSC clocksource is wrongly judged as unstable watchdog like 'jiffies', HPET on some platforms like Skylake 4S. 

For normal cases, we can use nr_online_nodes <= 4 as a quick workaround for this issue. However, there are many cases that 'nr_online_nodes' could have issue. Intel is still working on a formal fix, the patch in this PR is a more general fix but still have open under discussion.

Generally, there are some corner cases, but we can use this for a temporary fix to this issue. In next step, we need to update this fix after upstream merging the final solution.
