config USB_MDC800
tristate "USB Mustek MDC800 Digital Camera support"
---help---
Say Y here if you want to connect this type of still camera to
your computer's USB port. This driver can be used with gphoto 0.4.3
and higher (look at ).
To use it create a device node with "mknod /dev/mustek c 180 32" and
configure it in your software.
To compile this driver as a module, choose M here: the
module will be called mdc800.
config USB_MICROTEK
tristate "Microtek X6USB scanner support"
depends on SCSI
help
Say Y here if you want support for the Microtek X6USB and
possibly the Phantom 336CX, Phantom C6 and ScanMaker V6U(S)L.
Support for anything but the X6 is experimental.
Please report failures and successes.
The scanner will appear as a scsi generic device to the rest
of the system. Scsi support is required.
This driver can be compiled as a module, called microtek.

x86/microcode/intel: Drop stashed AP patch pointer optimization
This was meant to save us the scanning of the microcode containter in
the initrd since the first AP had already done that but it can also hurt
us:
Imagine a single hyperthreaded CPU (Intel(R) Atom(TM) CPU N270, for
example) which updates the microcode on the BSP but since the microcode
engine is shared between the two threads, the update on CPU1 doesn't
happen because it has already happened on CPU0 and we don't find a newer
microcode revision on CPU1.
Which doesn't set the intel_ucode_patch pointer and at initrd
jettisoning time we don't save the microcode patch for later
application.
Now, when we suspend to RAM, the loaded microcode gets cleared so we
need to reload but there's no patch saved in the cache.
Removing the optimization fixes this issue and all is fine and dandy.
