From 742632d237ce180439ab4af31e9891df0df81233 Mon Sep 17 00:00:00 2001 From: Yazen Ghannam Date: Fri, 4 May 2018 07:59:49 +0200 Subject: efi: Fix IA32/X64 Processor Error Record definition Based on UEFI 2.7 Table 255. Processor Error Record, the "Local APIC_ID" field is 8 bytes but Linux defines this field as 1 byte. Fix this in the struct cper_sec_proc_ia definition.

Do the section decoding in a new "cper-x86.c" file and add this to the Makefile depending on a new "UEFI_CPER_X86" config option. Print the Local APIC ID and CPUID info from the Processor Error Record. The "Processor Error Info" and "Processor Context" fields will be decoded in following patches. Based on UEFI 2.7 Table 252.
