The Xtensa architecture places literal pools in sections separate
from the instructions. The corresponsing text sections, therefore,
reference the .literal section, and we have to suppress those
warnings.The naming convention defines the name for a literal
section as .SECTION.literal, unless .SECTION is .text. In that case
the name is only .literal. Using strncmp() instead of strcmp()
to compare the from-section with .SECTION.init.refok in pattern 0
should not cause any regressions for other architectures.We also need to suppress warnings for two informational
sections (.xt.lit and .xt.prop) used by the Xtensa architecture.Signed-off-by: Chris Zankel

In the whitelist function of modpost now use the same
check to identify init_section as in other places of modpost.
This has the effect that we now recognize sections named
.init.text.19 as init sections and we no longer warn
when we see these.At the same time make surrounding code readable by dropping
use of temporary flags.Signed-off-by: Sam Ravnborg

I noticed, when running scripts/ver_linux on both a Gentoo system
and a Slackware system, that the line printing the C library
version looked a little odd. So I fixed it up to be in line with
all the rest.Old output:
Linux C Library > libc.2.5

(build as vmlinux.o) during first pass so skip the checks

Modify modpost (file2alias.c) to add acpi*:XYZ0001: alias in modules.alias
like:
grep acpi /lib/modules/2.6.22-rc4-default/modules.alias
alias acpi*:SNY5001:* sony_laptop
alias acpi*:SNY6001:* sony_laptop
for e.g. the sony_laptop module.
This module matches against all ACPI devices with a HID or CID of SNY5001
or SNY6001Export an uevent and modalias sysfs file containing the string:
[MODALIAS=]acpi:PNP0C0C:
additional CIDs are concatenated at the end.Signed-off-by: Thomas Renninger

I recently ran Lindent over the AdvanSys driver and it moved the
comments on #else and #endif lines way over to the right:#else /* ADVANSYS_DEBUG */
This doesn't match what I expect from kernel style, but it is
documented. We just need another flag to indent to make this look like:#else /* ADVANSYS_DEBUG */

KSYM_NAME_LEN is peculiar in that it does not include the space for the
trailing '\0', forcing all users to use KSYM_NAME_LEN + 1 when allocating
buffer. This is nonsense and error-prone. Moreover, when the caller
forgets that it's very likely to subtly bite back by corrupting the stack
because the last position of the buffer is always cleared to zero.This patch increments KSYM_NAME_LEN by one and updates code accordingly.
* off-by-one bug in asm-powerpc/kprobes.h::kprobe_lookup_name() macro
is fixed.* Where MODULE_NAME_LEN and KSYM_NAME_LEN were used together,
MODULE_NAME_LEN was treated as if it didn't include space for the
trailing '\0'. Fix it.Signed-off-by: Tejun Heo

The only in-kernel user of "memmem" is scripts/kallsyms.c and it only
uses it to find tokens that are 2 bytes in size. It is trivial to
replace it with a simple function that finds 2-byte tokens.This should help users from systems that don't have the memmem GNU
extension available.Signed-off-by: Paulo Marques

Normally generated values (Kconfig entries without a prompt) are cleared as
they are regenerated anyway and so they appear as new should they become
visible and defaults work as expected (once a value is set defaults aren't
used anymore).The detection whether a value is generated or not is only based on its
visibility status, which can quickly change for a lot of symbols by just
removing a single line from .config or adding a dependency to Kconfig as you
noticed.The patch now suppresses this logic when .config and Kconfig aren't in sync
and .config needs to be updated, so that you can remove now a random value
from .config and oldconfig won't reask for many other values.Signed-off-by: Roman Zippel

The sed expression used at the moment in scripts/Makefile.headersinst
relies on the (handy) GNU extension where you can escape ERE's in an
otherwise BRE without using the GNU -r option. The following patch
replaces this "\+" usage with a functionally equivalent POSIX BRE compliant
"\{1,\}". Tested with `make headers_install` against blackfin/x86_64/i386
targets.Stupid whiny OS X users and their crappy sed ;)

gcc puts data into .data.rel or .data.rel.* on some architectures (e.g.

Previously we did do the check on the .o files used to link
vmlinux but that failed to find questionable references across
the .o files.
Create a dedicated vmlinux.o file used only for section mismatch checks
that uses the defualt linker script so section does not get renamed.The vmlinux.o may later be used as part of the the final link of vmlinux
but for now it is used fo section mismatch only.
For a defconfig build this is instant but for an allyesconfig this
add two minutes to a full build (that anyways takes ~2 hours).Signed-off-by: Sam Ravnborg

Massimo Maiurana reported that
update-po-config was broken:
1) spelling errors in Makefile so arch/um failed
2) UTF-8 was not supportedThe following patch address the above problems.
kxgettext now append the output to the .pot file
generated by xgettext - so we have a header.
In all places UFT-8 is specifed so we now flawlessly
support UTF-8.
The Kconfig files had an empty string in a few cases -
these are now supressed in kxgettext.With this the translators can now pick up where they left
and get it all translated.
There are ~11000 strings to be translated...Signed-off-by: Sam Ravnborg
