Except for\ns390 and sparc64 all implementations of the sys_ipc are nearly identical.\n\nThere are slight differences in the types of the parameters, where mips\nand powerpc as the only 64-bit architectures with sys_ipc use unsigned\nlong for the \"third\" argument as it gets casted to a pointer later, while\nit traditionally is an \"int\" like most other paramters. frv goes even\nfurther and uses unsigned long for all parameters execept for \"ptr\" which\nis a pointer type everywhere. The change from int to unsigned long for\n\"third\" and back to \"int\" for the others on frv should be fine due to the\nin-register calling conventions for syscalls (we already had a similar\nissue with the generic sys_ptrace), but I\u0027d prefer to have the arch\nmaintainers looks over this in details.\n\nExcept for that h8300, m68k and m68knommu lack an impplementation of the\nsemtimedop sub call which this patch adds, and various architectures have\ngets used - at least on i386 it seems superflous as the compat code on\nx86-64 and ia64 doesn\u0027t even bother to implement it.\n\n[akpm@linux-foundation.org: add sys_ipc to sys_ni.c]\nSigned-off-by: Christoph Hellwig \u003chch@lst.de\u003e\nCc: Ralf Baechle \u003cralf@linux-mips.org\u003e\nCc: Benjamin Herrenschmidt \u003cbenh@kernel.crashing.org\u003e\nCc: Paul Mundt \u003clethal@linux-sh.org\u003e\nCc: Jeff Dike \u003cjdike@addtoit.com\u003e\nCc: Hirokazu Takata \u003ctakata@linux-m32r.org\u003e\nCc: Thomas Gleixner \u003ctglx@linutronix.de\u003e\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nReviewed-by: H.

With pending\ncode like hw-breakpoints support the \u0027counter\u0027 name is less and\nless appropriate.\n\nAll in one, we\u0027ve decided to rename the subsystem to \u0027performance\nevents\u0027 and to propagate this rename through all fields, variables\nand API names. (in an ABI compatible fashion)\n\nThe word \u0027event\u0027 is also a bit shorter than \u0027counter\u0027 - which makes\nit slightly more convenient to write/handle as well.\n\nThanks goes to Stephane Eranian who first observed this misnomer and\nsuggested a rename.\n\nUser-space tooling and ABI compatibility is not affected - this patch\nshould be function-invariant. (Also, defconfigs were not touched to\nkeep the size down.)\n\nThis patch has been generated via the following script:\n\n FILES\u003d$(find * -type f | grep -vE \u0027oprofile|[^K]config\u0027)\n\n sed -i \\\n -e \u0027s/PERF_EVENT_/PERF_RECORD_/g\u0027 \\\n -e \u0027s/PERF_COUNTER/PERF_EVENT/g\u0027 \\\n -e \u0027s/perf_counter/perf_event/g\u0027 \\\n -e \u0027s/nb_counters/nb_events/g\u0027 \\\n -e \u0027s/swcounter/swevent/g\u0027 \\\n -e \u0027s/tpcounter_event/tp_event/g\u0027 \\\n $FILES\n\n for N in $(find . -name perf_counter.[ch]); do\n M\u003d$(echo $N | sed \u0027s/perf_counter/perf_event/g\u0027)\n mv $N $M\n done\n\n FILES\u003d$(find . -name perf_event.*)\n\n sed -i \\\n -e \u0027s/COUNTER_MASK/REG_MASK/g\u0027 \\\n -e \u0027s/COUNTER/EVENT/g\u0027 \\\n -e \u0027s/\\\u003cevent\\\u003e/event_id/g\u0027 \\\n -e \u0027s/counter/event/g\u0027 \\\n -e \u0027s/Counter/Event/g\u0027 \\\n $FILES\n\n... to keep it as correct as possible. This script can also be\nused by anyone who has pending perfcounters patches - it converts\na Linux kernel tree over to the new naming. We tried to time this\nchange to the point in time where the amount of pending patches\nis the smallest: the end of the merge window.\n\nNamespace clashes were fixed up in a preparatory patch - and some\nstylistic fallout will be fixed up in a subsequent patch.\n\n( NOTE: \u0027counters\u0027 are still the proper terminology when we deal\n with hardware registers - and these sed scripts are a bit\n over-eager in renaming them. I\u0027ve undone some of that, but\n in case there\u0027s something left where \u0027counter\u0027 would be\n better than \u0027event\u0027 we can undo that on an individual basis\n instead of touching an otherwise nicely automated patch. )\n\nSuggested-by: Stephane Eranian \u003ceranian@google.com\u003e\nAcked-by: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nAcked-by: Paul Mackerras \u003cpaulus@samba.org\u003e\nReviewed-by: Arjan van de Ven \u003carjan@linux.intel.com\u003e\nCc: Mike Galbraith \u003cefault@gmx.de\u003e\nCc: Arnaldo Carvalho de Melo \u003cacme@redhat.com\u003e\nCc: Frederic Weisbecker \u003cfweisbec@gmail.com\u003e\nCc: Steven Rostedt \u003crostedt@goodmis.org\u003e\nCc: Benjamin Herrenschmidt \u003cbenh@kernel.crashing.org\u003e\nCc: David Howells \u003cdhowells@redhat.com\u003e\nCc: Kyle McMartin \u003ckyle@mcmartin.ca\u003e\nCc: Martin Schwidefsky \u003cschwidefsky@de.ibm.com\u003e\nCc: \"David S.

Why?\nBecause when we have it like this, the 64-bit system calls now don\u0027t use\nthe \"pos_high\" argument at all, and it makes more sense for the native\nsystem call to simply match the user-mode prototype.\n\nThis results in a much more natural calling convention, and allows the\ncompiler to generate much more straightforward code. On x86-64, we now\ngenerate\n\n testq %rcx, %rcx # pos_l\n js .L122 #,\n movq %rcx, -48(%rbp) # pos_l, pos\n\nfrom the C source\n\n loff_t pos \u003d pos_from_hilo(pos_h, pos_l);\n\t...\n if (pos \u003c 0)\n return -EINVAL;\n\nand the \u0027pos_h\u0027 register isn\u0027t even touched.

You can\njust do\n\n\t#define HALF_BITS (sizeof(unsigned long)*4)\n\t__syscall(PWRITEV, fd, iov, count, offset, (offset \u003e\u003e HALF_BITS) \u003e\u003e HALF_BITS);\n\nor something like that. That way the user mode wrapper will also be\nnicely passing in a zero (it won\u0027t actually have to do the shifts, the\ncompiler will understand what is going on) for the last argument.\n\nAnd that is a good idea, even if nobody will necessarily ever care: if\nwe ever do move to a 128-bit lloff_t, this particular system call might\nbe left alone. Of course, that will be the least of our worries if we\nreally ever need to care, so this may not be worth really caring about.\n\n[ Fixed for lost \u0027loff_t\u0027 cast noticed by Andrew Morton ]\n\nAcked-by: Gerd Hoffmann \u003ckraxel@redhat.com\u003e\nCc: H.
