x86_64 allmodconfig gives me

{standard input}: Assembler messages:
{standard input}:300: Error: suffix or operands invalid for `mov'

due to

movl %rax,%eax # tmp70

in olpc_xo1_do_sleep().


Also, this checkpatch warning

WARNING: struct platform_suspend_ops should normally be const
#502: FILE: arch/x86/platform/olpc/xo1.c:106:
+static struct platform_suspend_ops xo1_suspend_ops = {

seems valid.


Also, something in today's linux-next has mucked up the x86 Kconfig:

drivers/platform/x86/Kconfig:422:error: recursive dependency detected!
drivers/platform/x86/Kconfig:422: symbol EEEPC_WMI depends on ACPI_WMI
drivers/platform/x86/Kconfig:438: symbol ACPI_WMI is selected by ACER_WMI
drivers/platform/x86/Kconfig:18: symbol ACER_WMI depends on LEDS_CLASS
