      "message": "arch/tile: handle rt_sigreturn() more cleanly\n\nThe current tile rt_sigreturn() syscall pattern uses the common idiom\nof loading up pt_regs with all the saved registers from the time of\nthe signal, then anticipating the fact that we will clobber the ABI\n\"return value\" register (r0) as we return from the syscall by setting\nthe rt_sigreturn return value to whatever random value was in the pt_regs\nfor r0.\n\nHowever, this breaks in our 64-bit kernel when running \"compat\" tasks,\nsince we always sign-extend the \"return value\" register to properly\nhandle returned pointers that are in the upper 2GB of the 32-bit compat\naddress space.  Doing this to the sigreturn path then causes occasional\nrandom corruption of the 64-bit r0 register.\n\nInstead, we stop doing the crazy \"load the return-value register\"\nhack in sigreturn.  We already have some sigreturn-specific assembly\ncode that we use to pass the pt_regs pointer to C code.  We extend that\ncode to also set the link register to point to a spot a few instructions\nafter the usual syscall return address so we don\u0027t clobber the saved r0.\nNow it no longer matters what the rt_sigreturn syscall returns, and the\npt_regs structure can be cleanly and completely reloaded.\n\nSigned-off-by: Chris Metcalf \u003ccmetcalf@tilera.com\u003e\n"

      "message": "asm-generic/stat.h: support 64-bit file time_t for stat()\n\nThe existing asm-generic/stat.h specifies st_mtime, etc., as a 32-value,\nand works well for 32-bit architectures (currently microblaze, score,\nand 32-bit tile).  However, for 64-bit architectures it isn\u0027t sufficient\nto return 32 bits of time_t; this isn\u0027t good insurance against the 2037\nrollover.  (It also makes glibc support less convenient, since we can\u0027t\nuse glibc\u0027s handy STAT_IS_KERNEL_STAT mode.)\n\nThis change extends the two \"timespec\" fields for each of the three atime,\nmtime, and ctime fields from \"int\" to \"long\".  As a result, on 32-bit\nplatforms nothing changes, and 64-bit platforms will now work as expected.\n\nThe only wrinkle is 32-bit userspace under 64-bit kernels taking advantage\nof COMPAT mode.  For these, we leave the \"struct stat64\" definitions with\nthe \"int\" versions of the time_t and nsec fields, so that architectures\ncan implement compat_sys_stat64() and friends with sys_stat64(), etc.,\nand get the expected 32-bit structure layout.  This requires a\nfield-by-field copy in the kernel, implemented by the code guarded\nunder __ARCH_WANT_STAT64.\n\nThis does mean that the shape of the \"struct stat\" and \"struct stat64\"\nstructures is different on a 64-bit kernel, but only one of the two\nstructures should ever be used by any given process: \"struct stat\"\nis meant for 64-bit userspace only, and \"struct stat64\" for 32-bit\nuserspace only.  (On a 32-bit kernel the two structures continue to have\nthe same shape, since \"long\" is 32 bits.)\n\nThe alternative is keeping the two structures the same shape on 64-bit\nkernels, which means a 64-bit time_t in \"struct stat64\" for 32-bit\nprocesses.  This is a little unnatural since 32-bit userspace can\u0027t\ndo anything with 64 bits of time_t information, since time_t is just\n\"long\", not \"int64_t\"; and in any case 32-bit userspace might expect\nto be running under a 32-bit kernel, which can\u0027t provide the high 32\nbits anyway.  In the case of a 32-bit kernel we\u0027d then be extending the\nkernel\u0027s 32-bit time_t to 64 bits, then truncating it back to 32 bits\nagain in userspace, for no particular reason.  And, as mentioned above,\nif we have 64-bit time_t for 32-bit processes we can\u0027t easily use glibc\u0027s\nSTAT_IS_KERNEL_STAT, since glibc\u0027s stat structure requires an embedded\n\"struct timespec\", which is a pair of \"long\" (32-bit) values in a 32-bit\nuserspace.  \"Inventive\" solutions are possible, but are pretty hacky.\n\nSigned-off-by: Chris Metcalf \u003ccmetcalf@tilera.com\u003e\nAcked-by: Arnd Bergmann \u003carnd@arndb.de\u003e\n"

Rather than trying to tease\napart precisely which things changed due to which type of code\nreview, this commit includes various cleanups in the code:\n\n- sparse: Add declarations in headers for globals.\n- sparse: Fix __user annotations.\n- sparse: Using gfp_t consistently instead of int.\n- sparse: removing functions not actually used.\n- checkpatch: Clean up printk() warnings by using pr_info(), etc.;\n  also avoid partial-line printks except in bootup code.\n  - checkpatch: Use exposed structs rather than typedefs.\n  - checkpatch: Change some C99 comments to C89 comments.\n\nIn addition, a couple of minor other changes are rolled in\nto this commit:\n\n- Add support for a \"raise\" instruction to cause SIGFPE, etc., to be raised.\n- Remove some compat code that is unnecessary when we fully eliminate\n  some of the deprecated syscalls from the generic syscall ABI.\n- Update the tile_defconfig to reflect current config contents.\n\nSigned-off-by: Chris Metcalf \u003ccmetcalf@tilera.com\u003e\nAcked-by: Arnd Bergmann \u003carnd@arndb.de\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"
