# # USB Class driver configuration # comment "USB Device Class drivers" config USB_ACM tristate "USB Modem (CDC ACM) support" depends on TTY ---help--- This driver supports USB modems and ISDN adapters which support the Communication Device Class Abstract Control Model interface. Please read for details. If your modem only reports "Cls=ff(vend.)" in the descriptors in /proc/bus/usb/devices, then your modem will not work with this driver. To compile this driver as a module, choose M here: the module will be called cdc-acm. config USB_PRINTER tristate "USB Printer support" help Say Y here if you want to connect a USB printer to your computer's USB port.

powerpc/mm: Fix spurrious segfaults on radix with autonuma
When autonuma (Automatic NUMA balancing) marks a PTE inaccessible it clears all the protection bits but leave the PTE valid. With the Radix MMU, an attempt at executing from such a PTE will take a fault with bit 35 of SRR1 set "SRR1_ISI_N_OR_G". It is thus incorrect to treat all such faults as errors. We should pass them to handle_mm_fault() for autonuma to deal with. The case of pages that are really not executable is handled by the existing test for VM_EXEC further down. That leaves us with catching the kernel attempts at executing user pages. We can catch that earlier, even before we do find_vma. It is never valid on powerpc for the kernel to take an exec fault to begin with. So fold that test with the existing test for the kernel faulting on kernel addresses to bail out early.
