* EDAC: Check for GHES preference in the chipset-specific EDAC driversJia He2022-10-211-0/+3
| | | | | | | | | | | | | | | | Call ghes_get_devices() to check whether ghes_edac should be used on the platform where it is preferred over the corresponding chipset-specific EDAC driver. Unlike the existing edac_get_owner() check, the ghes_get_devices() check works independent to the module_init ordering.

| | | | | | | | | | | | | | Symbol 'lmc_dfs_ents' is not used outside of thunderx_edac.c, so make it static: drivers/edac/thunderx_edac.c:457:22: warning: symbol 'lmc_dfs_ents' was not declared.

* EDAC, thunderx: Remove VLA usageKees Cook2018-07-091-5/+9
| | | | | | | | | | | | | | In the quest to remove all stack VLA usage from the kernel[1], switch to using a kmalloc-allocated buffer instead of stack space. This should be fine since the existing routine is allocating memory too.
