Jan Beulich 7ad1227818 kconfig: fix undesirable side effect of adding "visible" menu attribute
This lead to non-selected, non-user-selectable options to be written
out to .config. This is not only pointless, but also preventing the
user to be prompted should any of those options eventually become
visible (e.g. by de-selecting the *_AUTO options the "visible"
attribute was added for.

Furthermore it is quite logical for the "visible" attribute of a menu
to control the visibility of all contained prompts, which is what the
patch does.

John Reiser e63233f75a ftrace: Have recordmcount honor endianness in fn_ELF_R_INFO
It looks to me like the change which introduced "virtual functions"
forgot about cross-platform endianness.

Thank you to Arnaud for supplying before+after data files do_mounts*.o.

This fixes a MIPS build failure triggered by recordmcount.

Wu Zhangjin 412910cd04 ftrace/MIPS: Add module support for C version of recordmcount
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.

Steven Rostedt 8ef17fa2ef kconfig: Have streamline_config process menuconfigs too
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.

Steven Rostedt 20d1904733 kconfig: Fix streamline_config to read multi line deps in Kconfig files
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.

besides "sys_*".

Andy Whitcroft 01464f30a9 checkpatch: statement/block context analyser should look at sanitised lines
When tracking context to find a block or statement we need to use the
sanitised lines, else perentheses '(' & ')' and braces '{' & '}' can throw
the scanner out.  Also fix up a couple of error outputs which include
those sanitised lines incorrectly.

Perhaps these need to be added to checkpatch.

Rabin Vincent 3bf9a009fc checkpatch: check for incorrect permissions
Throw an error when a source file has been given execute permissions using
the mode change line present in git diffs.  Also alow the filename
matching to use the "diff" line in addition to the "+++" line, since the
mode change lines appear before any "+++" lines.

Andy Whitcroft 9fe287d79b checkpatch: ensure kconfig help checks only apply when we are adding help
When checking the length of the help we need to be sure we are seeing the
whole story before erroring.  Firstly we only want to check when adding
the help in the first place.  Second we need to be sure that we are seeing
the end of the entry, nominally when there is no context below or that
context shows the start of the next entry.
