Hi Len,
After merging the acpi tree, today's linux-next build (x86_64
allmodconfig) failed like this:
drivers/acpi/debugfs.c: In function 'cm_write':
drivers/acpi/debugfs.c:36: error: implicit declaration of function 'copy_from_user'
Caused by commit c0b82d427637c7598af5d7926187a7781c03bce8 ("ACPI:
introduce drivers/acpi/debugfs.c"), interacting with something that
stopped linux/uaccess.h from being implicitly included. See Rule 1 in
Documentation/SubmitChecklist.
I have added the following patch for today:
From: Stephen Rothwell <sfr@xxxxxxxxxxxxxxxx>
Date: Fri, 13 Aug 2010 10:52:30 +1000
Subject: [PATCH] acpi: using copy_from_user needs linux/uaccess.h
fixes this build error:
drivers/acpi/debugfs.c: In function 'cm_write':
drivers/acpi/debugfs.c:36: error: implicit declaration of function 'copy_from_user'
