* | x86 microcode: revert some work_on_cpuHugh Dickins2009-04-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Revert part of af5c820a3169e81af869c113e18ec7588836cd50 ("x86: cpumask: use work_on_cpu in arch/x86/kernel/microcode_core.c") That change is causing only one Intel CPU's microcode to be updated e.g. microcode: CPU3 updated from revision 0x9 to 0x17, date = 2005-04-22 where before it announced that also for CPU0 and CPU1 and CPU2. We cannot use work_on_cpu() in the CONFIG_MICROCODE_OLD_INTERFACE code, because Intel's request_microcode_user() involves a copy_from_user() from /sbin/microcode_ctl, which therefore needs to be on that CPU at the time.

This confuses the kernel and it ends up crashing on an xsetbv instruction. At boot time, try to set cr4.OSXSAVE, and mask XSAVE out of cpuid it we can't. This will produce a spurious error from Xen, but allows us to support XSAVE if/when Xen does. This also factors out the cpuid mask decisions to boot time.

The other one is accessible through GPIO pin 1. Sadly, this pin is being multiplexed with UART0 input, so enabling it as interrupt source (as implied by the gpio-keys driver) is not possible unless UART0 has been turned off. The later one though is a rather bad idea as the Routerboard is an embedded device with only a single serial port, so it's almost always used as serial console device. This patch adds a driver based on INPUT_POLLDEV, which disables the UART and reconfigures GPIO pin 1 temporarily while reading the button state. This procedure works fine and has been tested as part of another, unpublished driver for this device. Signed-off-by: Phil Sutter <n0-1@freewrt.org> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
