with pointer array\n\nCurrently the syscall_meta structures for the syscall tracepoints are\nplaced in the __syscall_metadata section, and at link time, the linker\nmakes one large array of all these syscall metadata structures. On boot\nup, this array is read (much like the initcall sections) and the syscall\ndata is processed.\n\nThe problem is that there is no guarantee that gcc will place complex\nstructures nicely together in an array format. Two structures in the\nsame file may be placed awkwardly, because gcc has no clue that they\nare suppose to be in an array.\n\nA hack was used previous to force the alignment to 4, to pack the\nstructures together. But this caused alignment issues with other\narchitectures (sparc).\n\nInstead of packing the structures into an array, the structures\u0027 addresses\nare now put into the __syscall_metadata section. As pointers are always the\nnatural alignment, gcc should always pack them tightly together\n(otherwise initcall, extable, etc would also fail).\n\nBy having the pointers to the structures in the section, we can still\niterate the trace_events without causing unnecessary alignment problems\nwith other architectures, or depending on the current behaviour of\ngcc that will likely change in the future just to tick us kernel developers\noff a little more.\n\nThe __syscall_metadata section is also moved into the .init.data section\nas it is now only needed at boot up.\n\nSuggested-by: David Miller \u003cdavem@davemloft.net\u003e\nAcked-by: David S.

Implement an approach proposed by David Miller:\nuse an array of const pointers to refer to the individual structures, and export\nthis pointer array through the linker script rather than the structures per se.\nIt will consume 32 extra bytes per tracepoint (24 for structure padding and 8\nfor the pointers), but are less likely to break due to compiler changes.\n\nHistory:\n\ncommit 7e066fb8 tracepoints: add DECLARE_TRACE() and DEFINE_TRACE()\nadded the aligned(32) type and variable attribute to the tracepoint structures\nto deal with gcc happily aligning statically defined structures on 32-byte\nmultiples.\n\nOne attempt was to use a 8-byte alignment for tracepoint structures by applying\nboth the variable and type attribute to tracepoint structures definitions and\ndeclarations. It worked fine with gcc 4.5.1, but broke with gcc 4.4.4 and 4.4.5.\n\nThe reason is that the \"aligned\" attribute only specify the _minimum_ alignment\nfor a structure, leaving both the compiler and the linker free to align on\nlarger multiples. Because tracepoint.c expects the structures to be placed as an\narray within each section, up-alignment cause NULL-pointer exceptions due to the\nextra unexpected padding.\n\n(this patch applies on top of -tip)\n\nSigned-off-by: Mathieu Desnoyers \u003cmathieu.desnoyers@efficios.com\u003e\nAcked-by: David S.

On boot up, this array is read (much like\nthe initcall sections) and the events are processed.\n\nThe problem is that there is no guarantee that gcc will place complex\nstructures nicely together in an array format. Two structures in the\nsame file may be placed awkwardly, because gcc has no clue that they\nare suppose to be in an array.\n\nA hack was used previous to force the alignment to 4, to pack the\nstructures together. But this caused alignment issues with other\narchitectures (sparc).\n\nInstead of packing the structures into an array, the structures\u0027 addresses\nare now put into the _ftrace_event section. As pointers are always the\nnatural alignment, gcc should always pack them tightly together\n(otherwise initcall, extable, etc would also fail).\n\nBy having the pointers to the structures in the section, we can still\niterate the trace_events without causing unnecessary alignment problems\nwith other architectures, or depending on the current behaviour of\ngcc that will likely change in the future just to tick us kernel developers\noff a little more.\n\nThe _ftrace_event section is also moved into the .init.data section\nas it is now only needed at boot up.\n\nSuggested-by: David Miller \u003cdavem@davemloft.net\u003e\nCc: Mathieu Desnoyers \u003cmathieu.desnoyers@efficios.com\u003e\nAcked-by: David S.
