From e147133a42cb9df6cbc99503fdf58d0e6388bf2a Mon Sep 17 00:00:00 2001 From: James Morse Date: Tue, 29 Jan 2019 18:48:40 +0000 Subject: ACPI / APEI: Make hest.c manage the estatus memory pool ghes.c has a memory pool it uses for the estatus cache and the estatus queue. The cache is initialised when registering the platform driver. For the queue, an NMI-like notification has to grow/shrink the pool as it is registered and unregistered. This is all pretty noisy when adding new NMI-like notifications, it would be better to replace this with a static pool size based on the number of users. As a precursor, move the call that creates the pool from ghes_init(), into hest.c. Later this will take the number of ghes entries and consolidate the queue allocations. Remove ghes_estatus_pool_exit() as hest.c doesn't have anywhere to put this. The pool is now initialised as part of ACPI's subsys_initcall(): (acpi_init(), acpi_scan_init(), acpi_pci_root_init(), acpi_hest_init()) Before this patch it happened later as a GHES specific device_initcall().
