The fix lets new and old hypervisors and Linuxes interoperate more smoothly, so I've tagged it for stable@kernel.org so that older Linuxes will be able to boot under the newer hypervisor." * 'stable' of git://git.kernel.org/pub/scm/linux/kernel/git/cmetcalf/linux-tile: usb: tilegx: fix memleak when create hcd fail arch/tile: remove inline marking of EXPORT_SYMBOL functions rtc: rtc-tile: add missing platform_device_unregister() when module exit tile: support new Tilera hypervisor 2013-05-02T20:20:31Z Chris Metcalf 2013-05-02T19:29:04Z urn:sha1:c539914dcd9a68c63305e055b14115a6a19578a8 The Tilera hypervisor shipped in releases up through MDE 4.1 launches the client operating system (i.e. Linux) at privilege level 1 (PL1). Starting with MDE 4.2, as part of the work to enable KVM, the Tilera hypervisor launches Linux at PL2 instead. This commit makes the KERNEL_PL option default to 2 for tilegx, while still saying at 1 for tilepro, which doesn't have an updated hypervisor. It also explains how and when you might want to choose another value. In addition, we change a small buglet in the on-chip Ethernet driver, where we were failing to use the KERNEL_PL constant in an API call. To make the transition cleaner, this change also provides the updated hv_init() API for the new hypervisor that supports announcing Linux's compiled-in PL, so the hypervisor can generate a suitable error in the case of a mismatched hypervisor and Linux binary.

Arnd Bergman noted that the help text was slightly misleading and should be fixed to state that enabling this option isn't a problem when using pre 4.4 gcc. To simplify the rewording, consolidate the text into lib/Kconfig.debug and modify it there to be more explicit about when you should say N to this config. Also, make the text a bit more generic by stating that this option enables compile time checks so we can cover architectures which emit warnings vs. ones which emit errors. The details of how an architecture decided to implement the checks isn't as important as the concept of compile time checking of copy_from_user() calls. While we're doing this, remove all the copy_from_user_overflow() code that's duplicated many times and place it into lib/ so that any architecture supporting this option can get the function for free.
