ACPI/IORT: Check node revision for PMCG resources ACPI/IORT: Fix PMCG node single ID mapping handling ACPI: APD: Check for NULL pointer after calling devm_ioremap() devres_alloc()可能申请不到，加上空指针判断，是否devm_ioremap->devres_alloc()返回失败，需要合入 ACPI: NFIT: Use fallback node id when numa info in NFIT table is incorrect ACPI: custom_method: fix a possible memory leak ACPI: custom_method: fix potential use-after-free issue ACPI: configfs: add missing check after configfs_register_default_group() ACPICA: Fix exception code class checks 判断时要先与AE_CODE_MASK相与再判断，之前判断有问题 ACPICA: Do not increment operation_region reference counts for field units 服务器上发现如果同一个operation_region上声明了很多field_units会导致引用计数溢出，因为声明一个就会把opeartion region的引用计数加1 ，补丁修复了这个问题 通过在这种情况下不加1 ，需要合入 acpi/nfit: improve bounds checking for 'func' 如果用户态传入的值太大可能会导致越界访问，4.18 4.19前置补丁都合了，需要合入 ACPICA: Disassembler: create buffer fields in ACPI_PARSE_LOAD_PASS1 acpica 的bug，需要合入
