The gcc bug\napparently goes back to gcc-4.5, but slight optimization changes means\nthat it now showed up as a problem in 4.9.0 and 4.9.1.\n\nThe instruction scheduling problem causes gcc to schedule a spill\noperation to before the stack frame has been created, which in turn can\ncorrupt the spilled value if an interrupt comes in. There may be other\neffects of this bug too, but that\u0027s the code generation problem seen in\nMichel\u0027s case.\n\nThis is fixed in current gcc HEAD, but the workaround as suggested by\nMarkus Trippelsdorf is pretty simple: use -fno-var-tracking-assignments\nwhen compiling the kernel, which disables the gcc code that causes the\nproblem.

What this patch did was, among others, check the return value\nof misc_register and exit early if it encountered an error. Original\ncode sloppily didn\u0027t do that.\n\nHowever,\n\n cef12ee52b05 (\"xen/mce: Add mcelog support for Xen platform\")\n\nmade it so that xen\u0027s init routine xen_late_init_mcelog runs first. This\nwas needed for the xen mcelog device which is supposed to be independent\nfrom the baremetal one.\n\nInitially it was reported that misc_register() fails often on xen and\nthat\u0027s why it needed fixing. However, it is *supposed* to fail by\ndesign, when running in dom0 so that the xen mcelog device file gets\nregistered first.\n\nAnd *then* you need the notifier *not* unregistered on the error path so\nthat the timer does get deleted properly in the CPU hotplug notifier.\n\nBtw, this fix is needed also on baremetal in the unlikely event that\nmisc_register(\u0026mce_chrdev_device) fails there too.\n\nI was unsure whether to rush it in now and decided to delay it to 3.17.\nHowever, xen people wanted it promoted as it breaks xen when doing cpu\nhotplug there. So, after a bit of simmering in tip/master for initial\nsmoke testing, let\u0027s move it to 3.16. It fixes a semi-regression which\ngot introduced in 3.16 so no need for stable tagging.\n\ntip/x86/ras contains that exact same commit but we can\u0027t remove it\nthere as it is not the last one.

For debugging via ptrace\nthe syscall entry code stores the complete register context on the\nstack. The badsys handlers only store the ENOSYS error code in the\nptrace register set and do not set %eax like a regular syscall handler\nwould. The old resume_userspace call chain contains code that clobbers\n%eax and it restores %eax from the ptrace registers afterwards. The same\ngoes for the ptrace-enabled call chain. When ptrace is not used, the\nsyscall return value is the passed-in syscall number from the untouched\n%eax register.\n\nUse %eax as the return value register in syscall_badsys and\nsysenter_badsys, like a real syscall handler does, and have the caller\npush the value onto the stack for ptrace access.\n\nSigned-off-by: Sven Wegener \u003csven.wegener@stealer.net\u003e\nLink: http://lkml.kernel.org/r/alpine.LNX.2.11.1407221022380.31021@titan.int.lan.stealer.net\nReviewed-and-tested-by: Andy Lutomirski \u003cluto@amacapital.net\u003e\nCc: \u003cstable@vger.kernel.org\u003e # If 554086d is backported\nSigned-off-by: H.

The second commit had the side effect of triggering a\nBUG_ON during DLPAR, migration and suspend/resume operations as a result of\ndynamically added nodes being uninitialized.\n\nThis patch fixes this by adding of_node_init calls in place of the previously\nremoved kref_init calls.\n\nFixes: 0829f6d1f69e (\"of: device_node kobject lifecycle fixes\")\nCc: stable@vger.kernel.org\nSigned-off-by: Tyrel Datwyler \u003ctyreld@linux.vnet.ibm.com\u003e\nAcked-by: Nathan Fontenot \u003cnfont@linux.vnet.ibm.com\u003e\nAcked-by: Grant Likely \u003cgrant.likely@linaro.org\u003e\nSigned-off-by: Benjamin Herrenschmidt \u003cbenh@kernel.crashing.org\u003e\n" }, { "commit": "dad6f37c2602e4af6c3aecfdb41f2d8bd4668163", "tree": "6dbff4666fddea21b95c4c11cc58de6ec6a83f9d", "parents": [ "e698b9667879b79e479cc985f9d74ecf126e343e" ], "author": { "name": "Aneesh Kumar K.V", "email": "aneesh.kumar@linux.vnet.ibm.com", "time": "Tue Jul 15 20:22:30 2014 +0530" }, "committer": { "name": "Benjamin Herrenschmidt", "email": "benh@kernel.crashing.org", "time": "Tue Jul 22 15:55:55 2014 +1000" }, "message": "powerpc: subpage_protect: Increase the array size to take care of 64TB\n\nWe now support TASK_SIZE of 16TB, hence the array should be 8.\n\nFixes the below crash:\n\nUnable to handle kernel paging request for data at address 0x000100bd\nFaulting instruction address: 0xc00000000004f914\ncpu 0x13: Vector: 300 (Data Access) at [c000000fea75fa90]\n pc: c00000000004f914: .sys_subpage_prot+0x2d4/0x5c0\n lr: c00000000004fb5c: .sys_subpage_prot+0x51c/0x5c0\n sp: c000000fea75fd10\n msr: 9000000000009032\n dar: 100bd\n dsisr: 40000000\n current \u003d 0xc000000fea6ae490\n paca \u003d 0xc00000000fb8ab00 softe: 0 irq_happened: 0x00\n pid \u003d 8237, comm \u003d a.out\nenter ? for help\n[c000000fea75fe30] c00000000000a164 syscall_exit+0x0/0x98\n\nSigned-off-by: Benjamin Herrenschmidt \u003cbenh@kernel.crashing.org\u003e\n" }, { "commit": "e698b9667879b79e479cc985f9d74ecf126e343e", "tree": "6072870769c85d687c774bd8c532ad9fb1a172f8", "parents": [ "bd6ba3518fcb2539d83163a3f486d09411bc535d" ], "author": { "name": "Paul Mackerras", "email": "paulus@samba.org", "time": "Sat Jul 19 17:47:57 2014 +1000" }, "committer": { "name": "Benjamin Herrenschmidt", "email": "benh@kernel.crashing.org", "time": "Tue Jul 22 15:55:51 2014 +1000" }, "message": "powerpc: Fix bugs in emulate_step()\n\nThis fixes some bugs in emulate_step().
