Parse the ACPI MRRM table and save the max_mem_region value. Provide a function for resctrl to collect that value.

However, this prevents RAS records coming in between the evged driver initialization and the HED driver initialization from being handled. If the number of such RAS records is above the APEI HEST error source number, the HEST resources may be exhausted, and that may affect subsequent RAS error reporting. To fix this issue, change the initcall level of HED to subsys_initcall and prevent the driver from being built as a module by changing ACPI_HED in Kconfig from "tristate" to "bool".

The laptop driver cannot work without EC, so also update the dependency of LOONGSON_LAPTOP to let it depend on APCI_EC.

Make this a user-visible configuration option that is default enabled on x86 but otherwise disabled, and that can never be enabled unless CONFIG_HAS_IOPORT is also available. The empty stubs in internal.h help ignore the EC code in configurations that don't support it. In order to see those stubs, the sbshc code also has to include this header and drop duplicate declarations. All the direct callers of ec_read/ec_write already had an x86 dependency and now also need to depend on APCI_EC.

Most of the operations involve iterating over elements of the table and filtering them. Simplify the process by implementing range of getters. While the acpi_nhlt_endpoint_mic_count() stands out a bit, it is a critical component for any AudioDSP driver to know how many digital microphones it is dealing with.

Moreover, the recipe for preparing a customized version of a given control method has changed at one point due to ACPICA changes, which has not been reflected in its documentation, so whoever used it before has had to adapt and it had gone unnoticed for a long time. This interface was a bad idea to start with and its implementation is fragile at the design level. It's been always conceptually questionable, problematic from the security standpoint and implemented poorly. Patches fixing its most apparent functional issues (for example, [2]) don't actually address much of the above. Granted, at the time it was introduced, there was no alternative, but there is the AML debugger in the kernel now and there is the configfs interface allowing custom ACPI tables to be loaded. The former can be used for extensive AML debugging and the latter can be use for testing new AML. [3] Accordingly, drop custom_method along with its (outdated anyway) documentation.
