[PATCH 00/11] platform/x86/amd/hsmp: Per-platform enabled-message bitmaps

[Suma Hegde <suma.hegde@amd.com>]

From: Suma Hegde <Suma.Hegde@amd.com>

This series introduces per-socket read/write enabled-message bitmaps so
the HSMP driver rejects unsupported messages before they reach the SMU.
Prep patches fix sock_ind bounds checking, move proto_ver onto
hsmp_socket, and reorder helpers for the validation path. Later patches
populate the bitmaps statically and via HSMP_GET_ENABLED_HSMP_CMDS
(6th Gen AMD EPYC Server and future platforms), and update sysfs/hwmon
file modes from the bitmaps.

Client platforms skip bitmap init, populate, and validation until
dedicated client tables exist; shared smu_fw_version and
protocol_version sysfs attributes remain visible there.

Patch summary:
  01/11  platform/x86/amd/hsmp: Fix sock_ind bounds check in is_bin_visible
  02/11  platform/x86/amd/hsmp: Move proto_ver to hsmp_socket structure
  03/11  platform/x86/amd/hsmp: Null-check drvdata in hsmp_is_sock_attr_visible()
  04/11  platform/x86/amd/hsmp: Move is_get_msg() before validate_message()
  05/11  platform/x86/amd/hsmp: Use local sock pointer in init_acpi()
  06/11  platform/x86/amd/hsmp: Move the sock_ind bound check before validate_message()
  07/11  platform/x86/amd/hsmp: Add per-platform bitmap to validate HSMP messages
  08/11  platform/x86/amd/hsmp: Populate the bitmaps dynamically on 6th Gen AMD EPYC Server
  09/11  platform/x86/amd/hsmp: Populate the bitmaps dynamically for future platforms
  10/11  platform/x86/amd/hsmp: Relocate to_hsmp_sys_attr() macro
  11/11  platform/x86/amd/hsmp: Update sysfs and hwmon file modes based on platform capabilities
