But, it\u0027s not defined in linux/mmzone.h but defined in\n/arch/???/include/mmzone.h which is included only under\nCONFIG_NEED_MULTIPLE_NODES\u003dy.\n\nThen, we see\n  mm/page_cgroup.c: In function \u0027page_cgroup_init\u0027:\n  mm/page_cgroup.c:308: error: implicit declaration of function \u0027node_start_pfn\u0027\n  mm/page_cgroup.c:309: error: implicit declaration of function \u0027node_end_pfn\u0027\n\nSo, fixiing page_cgroup.c is an idea...\n\nBut node_start_pfn()/node_end_pfn() is a very generic macro and\nshould be implemented in the same manner for all archs.\n(m32r has different implementation...)\n\nThis patch removes definitions of node_start/end_pfn() in each archs\nand defines a unified one in linux/mmzone.h.

      "message": "arch/tile: more /proc and /sys file support\n\nThis change introduces a few of the less controversial /proc and\n/proc/sys interfaces for tile, along with sysfs attributes for\nvarious things that were originally proposed as /proc/tile files.\nIt also adjusts the \"hardwall\" proc API.\n\nArnd Bergmann reviewed the initial arch/tile submission, which\nincluded a complete set of all the /proc/tile and /proc/sys/tile\nknobs that we had added in a somewhat ad hoc way during initial\ndevelopment, and provided feedback on where most of them should go.\n\nOne knob turned out to be similar enough to the existing\n/proc/sys/debug/exception-trace that it was re-implemented to use\nthat model instead.\n\nAnother knob was /proc/tile/grid, which reported the \"grid\" dimensions\nof a tile chip (e.g. 8x8 processors \u003d 64-core chip).  Arnd suggested\nlooking at sysfs for that, so this change moves that information\nto a pair of sysfs attributes (chip_width and chip_height) in the\n/sys/devices/system/cpu directory.  We also put the \"chip_serial\"\nand \"chip_revision\" information from our old /proc/tile/board file\nas attributes in /sys/devices/system/cpu.\n\nOther information collected via hypervisor APIs is now placed in\n/sys/hypervisor.  We create a /sys/hypervisor/type file (holding the\nconstant string \"tilera\") to be parallel with the Xen use of\n/sys/hypervisor/type holding \"xen\".  We create three top-level files,\n\"version\" (the hypervisor\u0027s own version), \"config_version\" (the\nversion of the configuration file), and \"hvconfig\" (the contents of\nthe configuration file).  The remaining information from our old\n/proc/tile/board and /proc/tile/switch files becomes an attribute\ngroup appearing under /sys/hypervisor/board/.\n\nFinally, after some feedback from Arnd Bergmann for the previous\nversion of this patch, the /proc/tile/hardwall file is split up into\ntwo conceptual parts.  First, a directory /proc/tile/hardwall/ which\ncontains one file per active hardwall, each file named after the\nhardwall\u0027s ID and holding a cpulist that says which cpus are enclosed by\nthe hardwall.  Second, a /proc/PID file \"hardwall\" that is either\nempty (for non-hardwall-using processes) or contains the hardwall ID.\n\nFinally, this change pushes the /proc/sys/tile/unaligned_fixup/\ndirectory, with knobs controlling the kernel code for handling the\nfixup of unaligned exceptions.\n\nReviewed-by: Arnd Bergmann \u003carnd@arndb.de\u003e\nSigned-off-by: Chris Metcalf \u003ccmetcalf@tilera.com\u003e\n"

      "message": "percpu: Always align percpu output section to PAGE_SIZE\n\nPercpu allocator honors alignment request upto PAGE_SIZE and both the\npercpu addresses in the percpu address space and the translated kernel\naddresses should be aligned accordingly.  The calculation of the\nformer depends on the alignment of percpu output section in the kernel\nimage.\n\nThe linker script macros PERCPU_VADDR() and PERCPU() are used to\ndefine this output section and the latter takes @align parameter.\nSeveral architectures are using @align smaller than PAGE_SIZE breaking\npercpu memory alignment.\n\nThis patch removes @align parameter from PERCPU(), renames it to\nPERCPU_SECTION() and makes it always align to PAGE_SIZE.  While at it,\nadd PCPU_SETUP_BUG_ON() checks such that alignment problems are\nreliably detected and remove percpu alignment comment recently added\nin workqueue.c as the condition would trigger BUG way before reaching\nthere.\n\nFor um, this patch raises the alignment of percpu area.  As the area\nis in .init, there shouldn\u0027t be any noticeable difference.\n\nThis problem was discovered by David Howells while debugging boot\nfailure on mn10300.\n\nSigned-off-by: Tejun Heo \u003ctj@kernel.org\u003e\nAcked-by: Mike Frysinger \u003cvapier@gentoo.org\u003e\nCc: uclinux-dist-devel@blackfin.uclinux.org\nCc: David Howells \u003cdhowells@redhat.com\u003e\nCc: Jeff Dike \u003cjdike@addtoit.com\u003e\nCc: user-mode-linux-devel@lists.sourceforge.net\n"

      "message": "arch/tile: fix deadlock bugs in rwlock implementation\n\nThe first issue fixed in this patch is that pending rwlock write locks\ncould lock out new readers; this could cause a deadlock if a read lock was\nheld on cpu 1, a write lock was then attempted on cpu 2 and was pending,\nand cpu 1 was interrupted and attempted to re-acquire a read lock.\nThe write lock code was modified to not lock out new readers.\n\nThe second issue fixed is that there was a narrow race window where a tns\ninstruction had been issued (setting the lock value to \"1\") and the store\ninstruction to reset the lock value correctly had not yet been issued.\nIn this case, if an interrupt occurred and the same cpu then tried to\nmanipulate the lock, it would find the lock value set to \"1\" and spin\nforever, assuming some other cpu was partway through updating it.  The fix\nis to enforce an interrupt critical section around the tns/store pair.\n\nIn addition, this change now arranges to always validate that after\na readlock we have not wrapped around the count of readers, which\nis only eight bits.\n\nSince these changes make the rwlock \"fast path\" code heavier weight,\nI decided to move all the rwlock code all out of line, leaving only the\nconventional spinlock code with fastpath inlines.  Since the read_lock\nand read_trylock implementations ended up very similar, I just expressed\nread_lock in terms of read_trylock.\n\nAs part of this change I also eliminate support for the now-obsolete\ntns_atomic mode.\n\nSigned-off-by: Chris Metcalf \u003ccmetcalf@tilera.com\u003e\n"

The set_pte_order()\nfunction was eliminated since the \"order\" argument wasn\u0027t being used.\n\nOne bug uncovered was in the PCI DMA code, which wasn\u0027t properly\nflushing the specified range.  This was benign with 64KB pages,\nbut with 4KB pages we were getting some larger flushes wrong.\n\nThe per-cpu memory reservation code also needed updating to\nconform with the newer percpu stuff; before it always chose 64KB,\nand that was always correct, but with 4KB granularity we now have\nto pay closer attention and reserve the amount of memory that will\nbe requested when the percpu code starts allocating.\n\nSigned-off-by: Chris Metcalf \u003ccmetcalf@tilera.com\u003e\n"

(Now they\u0027re blocked while we\u0027re executing the\ndowncall routine itself, but not while we\u0027re executing any subsequent\nsoftirq routines.)  The hypervisor is doing a very small amount of\nwork it no longer needs to do (masking INTCTRL_1 on entry to the client\ninterrupt routine), but doing so means that older versions of Tile Linux\nwill continue to work with a current hypervisor, so that seems reasonable.\n\nSigned-off-by: Chris Metcalf \u003ccmetcalf@tilera.com\u003e\n"

      "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"

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"

      "message": "arch/tile: correct double syscall restart for nested signals\n\nThis change is modelled on similar fixes for other architectures.\nThe pt_regs \"faultnum\" member is set to the trap (fault) number that\ncaused us to enter the kernel, and is INT_SWINT_1 for the syscall software\ninterrupt.  We already supported a pseudo value, INT_SWINT_1_SIGRETURN,\nthat we used for the rt_sigreturn syscall; it avoided the case where\none signal was handled, then we \"tail-called\" to another handler.\n\nThis change avoids the similar case where we start to call one handler,\nthen are preempted into another handler when we start trying to run\nthe first handler.  We clear -\u003efaultnum after calling handle_signal(),\nand to be paranoid also in the case where there was no signal to deliver.\n\nSigned-off-by: Chris Metcalf \u003ccmetcalf@tilera.com\u003e\n"
