Subject: [PATCH v4 1/3] powerpc/pseries: Update SCM hcall op-codes in hvcall.h
Date: Sat, 29 Jun 2019 21:36:08 +0530 [thread overview]
Message-ID: <20190629160610.23402-2-vaibhav@linux.ibm.com> (raw)
In-Reply-To: <20190629160610.23402-1-vaibhav@linux.ibm.com>
Update the hvcalls.h to include op-codes for new hcalls introduce to
manage SCM memory. Also update existing hcall definitions to reflect
current papr specification for SCM.
The removed hcall op-codes H_SCM_MEM_QUERY, H_SCM_BLOCK_CLEAR were
transient proposals and there support was never implemented by
Power-VM nor they were used anywhere in Linux kernel. Hence we don't
expect anyone to be impacted by this change.
Signed-off-by: Vaibhav Jain <vaibhav@linux.ibm.com>

* Updated the patch description mentioned current status of removed
hcall opcodes. [Mpe]

v2:
* None new patch in this series.
