      "message": "arch/tile: extend syscall ABI to set r1 on return as well.\n\nUntil now, the tile architecture ABI for syscall return has just been\nthat r0 holds the return value, and an error is only signalled like it is\nfor kernel code, with a negative small number.\n\nHowever, this means that in multiple places in userspace we end up writing\nthe same three-cycle idiom that tests for a small negative number for\nerror.  It seems cleaner to instead move that code into the kernel, and\nset r1 to hold zero on success or errno on failure; previously, r1 was\njust zeroed on return from the kernel (to avoid leaking kernel state).\nThis way a single conditional branch after the syscall is sufficient\nto test for the failure case.  The number of cycles taken is the same,\nbut the error-checking code is in just one place, so total code size is\nsmaller, and random userspace syscall code is easier to understand.\n\nSigned-off-by: Chris Metcalf \u003ccmetcalf@tilera.com\u003e\n"

      "message": "arch/tile: Add driver to enable access to the user dynamic network.\n\nThis network (the \"UDN\") connects all the cpus on the chip in a\nwormhole-routed dynamic network.  Subrectangles of the chip can\nbe allocated by a \"create\" ioctl on /dev/hardwall, and then to access the\nUDN in that rectangle, tasks must perform an \"activate\" ioctl on that\nsame file object after affinitizing themselves to a single cpu in\nthe region.  Sending a wormhole-routed message that tries to leave\nthat subrectangle causes all activated tasks to receive a SIGILL\n(just as they would if they tried to access the UDN without first\nactivating themselves to a hardwall rectangle).\n\nThe original submission of this code to LKML had the driver\ninstantiated under /proc/tile/hardwall.  Now we just use a character\ndevice for this, conventionally /dev/hardwall.  Some futures planning\nfor the TILE-Gx chip suggests that we may want to have other types of\ndevices that share the general model of \"bind a task to a cpu, then\n\u0027activate\u0027 a file descriptor on a pseudo-device that gives access to\nsome hardware resource\".  As such, we are using a device rather\nthan, for example, a syscall, to set up and activate this code.\n\nAs part of this change, the compat_ptr() declaration was fixed and used\nto pass the compat_ioctl argument to the normal ioctl.  So far we limit\ncompat code to 2GB, so the difference between zero-extend and sign-extend\n(the latter being correct, eventually) had been overlooked.\n\nSigned-off-by: Chris Metcalf \u003ccmetcalf@tilera.com\u003e\nAcked-by: Arnd Bergmann \u003carnd@arndb.de\u003e\n"
