From 4ac4c5fad8a320f75cb84543403fb8bae5ad2254 Mon Sep 17 00:00:00 2001 From: Bob Moore Date: Wed, 26 Feb 2014 10:28:32 +0800 Subject: ACPICA: Headers: Deploy #pragma pack (push) and (pop). Use push and pop to both guarantee that the correct alignment is used, and to restore the alignment to whatever it was before the header was included. It is reported that the #pragma pack(push/pop) directives are not supported by the specific GCCs, but this patch still doesn't affect kernel build as there are already #pragma pack([1]) directives used in the old ACPICA headers, which means there shouldn't be GCCs that are currently used to compile the ACPI kernels do not support #pragma pack() directives.
