2010-11-01kconfig: sym_expand_string_value: allow for string termination when reallocingAndy Whitcroft1-1/+1
When expanding a parameterised string we may run out of space, this triggers a realloc. When computing the new allocation size we do not allow for the terminating '\0'. Allow for this when calculating the new length. Signed-off-by: Andy Whitcroft <apw@canonical.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2010-10-29ftrace/MIPS: Add module support for C version of recordmcountWu Zhangjin2-4/+57
Since MIPS modules' address space differs from the core kernel space, to access the _mcount in the core kernel, the kernel functions in modules must use long call (-mlong-calls): load the _mcount address into one register and jump to the address stored by the register: c: 3c030000 lui v1,0x0 <--------> b label c: R_MIPS_HI16 _mcount c: R_MIPS_NONE *ABS* c: R_MIPS_NONE *ABS* 10: 64630000 daddiu v1,v1,0 10: R_MIPS_LO16 _mcount 10: R_MIPS_NONE *ABS* 10: R_MIPS_NONE *ABS* 14: 03e0082d move at,ra 18: 0060f809 jalr v1 label: In the old Perl version of recordmcount, we only need to record the position of the 1st R_MIPS_HI16 type of _mcount, and later, in ftrace_make_nop(), replace the instruction in this position by a "b label" and in ftrace_make_call(), replace it back. But, the default C version of recordmcount records all of the _mcount symbols, so, we must filter the 2nd _mcount like the Perl version of recordmcount does. The C version of recordmcount copes with the symbols before they are linked, So It doesn't know the type of the symbols and therefore can not filter the symbols as the Perl version of recordmcount does. But as we can see above, the 2nd _mcount symbols of the long call alawys follows the 1st _mcount symbol of the same long call, which means the offset from the 1st to the 2nd is fixed, it is 0x10-0xc = 4 here, 4 is the length of the 1st load instruciton, for MIPS has fixed length of instructions, this offset is always 4. And as we know, the _mcount is inserted into the entry of every kernel function, the offset between the other _mcount's is expected to be always bigger than 4. So, to filter the 2ns _mcount symbol of the long call, we can simply check the offset between two _mcount symbols, If it is 4, then, filter the 2nd _mcount symbol. To avoid touching too much code, an 'empty' function fn_is_fake_mcount() is added for all of the archs, and the specific archs can override it via chaning the function pointer: is_fake_mcount in do_file() with the e_machine. e.g. This patch adds MIPS_is_fake_mcount() to override the default fn_is_fake_mcount() pointed by is_fake_mcount. This fn_is_fake_mcount() checks if the _mcount symbol is fake, e.g. the 2nd _mcount symbol of the long call is fake, for there are 2 _mcount symbols mapped to one real mcount call, so, one of them is fake and must be filtered. This fn_is_fake_mcount() is called in sift_rel_mcount() after finding the _mcount symbols and before adding the _mcount symbol into mrelp, so, it can prevent the fake mcount symbol going into the last __mcount_loc table.

2010-10-29kconfig: Have streamline_config process menuconfigs tooSteven Rostedt1-2/+2
Some menuconfigs in the Kconfig files have prompts and dependencies. Currently, streamline_config misses these, and this can cause streamline_config to keep modules enabled that should not be, and even worse, not enable those that should. This patch makes streamline_config process menuconfigs just like it would process a config. Reported-by: member graysky <graysky@archlinux.us> Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
2010-10-29kconfig: Fix streamline_config to read multi line deps in Kconfig filesSteven Rostedt1-1/+18
I noticed that some Kconfig files have multi line dependencies that continue with a backslash. Those dependencies on the next line will be missed by streamline_config. For example: config CS89x0 tristate "CS89x0 support" depends on NET_ETHERNET && (ISA || EISA || MACH_IXDP2351 \ || ARCH_IXDP2X01 || MACH_MX31ADS) The "|| ARCH_IXDP2X01 || MACH_MX31ADS)" will not be processed. This patch adds code to handle this case. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>

The following incantation is triggering categorisation of its colon (:) as a binary form, which it is not: return foo ? (s8)bar : baz; Handle casts differently from types in the categoriser, allowing us to better track (s8)bar as a value and not a declaration.

2010-10-26checkpatch: ensure we do not collapse bracketed sections into constantsAndy Whitcroft1-3/+4
When determining if a return () sequence is a function style bracketing we simplify the expression one bracket at a time replacing each with a constant. However this can trigger a false merge with expressions as below: return (foo)0; Prevent this false merging.

2010-10-26checkpatch: fix regressions in "fix handling of leading spaces"Andy Whitcroft1-3/+6
The patch "checkpatch: fix handling of leading spaces" added checks for leading spaces on lines, but this introduces regressions. Firstly it does not correctly detect when we are in a comment. Secondly it does not allow for preprocessor command spacing. Finally it does not allow for label indentation which is required to be less than one tab.
