From: Shiju Jose <shiju.jose@huawei.com>

1. Support cpu fault isolation for the corrected and recoverable errors.
2. Add features and improvements to the HiSilicon vendor specific code.
3. Bug fix for a memory out-of-bounds issue.

Change History:
v1 -> v2
1. Use standard length PATH_MAX for path name space allocation
   to replace the macro MAX_PATH_LEN in the cpu fault isolation
   implementation.

Shengwei Luo (2):
  rasdaemon: Support cpu fault isolation for corrected errors
  rasdaemon: Support cpu fault isolation for recoverable errors

Shiju Jose (8):
  rasdaemon: Modify recording Hisilicon common error data
  rasdaemon: ras-mc-ctl: Modify error statistics for HiSilicon
    KunPeng9xx common errors
  rasdaemon: ras-mc-ctl: Reformat error info of the HiSilicon Kunpeng920
  rasdaemon: ras-mc-ctl: Add printing usage if necessary parameters are
    not passed for the vendor-error options
  rasdaemon: ras-mc-ctl: Add support to display the HiSilicon vendor
    errors for a specified module
  rasdaemon: ras-mc-ctl: Relocate reading and display Kunpeng920 errors
    to under Kunpeng9xx
  rasdaemon: ras-mc-ctl: Updated HiSilicon platform name
  rasdaemon: Fix for a memory out-of-bounds issue and optimized code to
    remove duplicate function.

When the corrected errors exceed the set limit in cycle, try to
offline the related cpu core.

When the recoverable errors in cpu core occurred, try to offline
the related cpu core.

From: Shiju Jose <shiju.jose@huawei.com>

The error statistics for the Hisilicon common
error need to do based on module, error severity etc.

Modify recording Hisilicon common error data as separate fields
in the sql db table instead of the combined single field.
