The page allocation failure messages include a line that looks like
page allocation failure. order:1, mode:0x4020
The mode is easy to translate but irritating for the lazy and a bit error
prone. This patch adds a very simple helper script gfp-translate for the
mode: portion of the page allocation failure messages. An example usage
looks like
mel@machina:~/linux-2.6 $ scripts/gfp-translate 0x4020
Source: /home/mel/linux-2.6
Parsing: 0x4020
#define __GFP_HIGH (0x20) /* Should access emergency pools? */
#define __GFP_COMP (0x4000) /* Add compound page metadata */
The script is not a work of art but it has come in handy for me a few
times so I thought I would share.

A new architecture should only define a minimal set of system
calls while still providing the full functionality. This version
of unistd.h has gone through intensive review to make sure that
by default it only enables syscalls that do not already have
a more featureful replacement.
It is modeled after the x86-64 version of unistd.h, which unifies
the syscall number definition and the actual system call table
in a single file, in order to keep them synchronized much more
easily.
This first version still keeps legacy system call definitions
around, guarded by various #ifdefs, and with numbers larger
than 1024. The idea behind this is to make it easier for
new architectures to transition from a full list to the reduced
set. In particular, the new microblaze architecture that should
migrate to using the generic ABI headers can at least use an
existing uClibc source tree without major rewrites during the
conversion.

When we had code like this in a header unifdef failed to
deduct that the expression was always false - and we had code exported
that was not intended for userspace.
#if defined(__KERNEL__) && !defined(__ASSEMBLY__)
int a;
#endif
This commit implment support in unidef which allows it to work out if
an #if expression always evaluates true or false for symbols which
are being undefined/always defined.
The patch is slightly more complicated than I'd hoped because unifdef
needs to see lines fully evaluated - doing otherwise causes it to
mark the line as "dirty" and copy it over no matter what.

Correct the regular expression in scripts/headers_check.pl to include '_'
as a valid character in the class; otherwise, the check will report a
"leaked" symbol of CONFIG_A_B_C as merely CONFIG_A.
This patch will make no difference whatsoever in the current kernel tree
as the call to the perl routine that does that check is currently
commented out:
&check_include();
&check_asm_types();
&check_sizetypes();
&check_prototypes();
# Dropped for now. Too much noise &check_config();
However, I noticed that problem when I was building the yum downloadable
kernel source rpm for fedora 11 (beta), which *does* run that check, and
that's where the problem became obvious.

The Debian packaging scripts created by the deb-pkg target do not pass
on the standard Debian maintainer script parameters to hook scripts,
which means that those scripts cannot tell whether they are being called
during e.g. install vs. upgrade, or removal vs. purge of the package.
As there are several variantions in how hook scripts are called from
kernel packages, we pass the parameters in the environment variable
DEB_MAINT_PARAMS rather than as extra arguments.

The warning appeared with the improved version of the
check of the flags in the sections.
That check already ignored sections named ".comment" - but SUSE store
additional info in the comment section and has named it in a SUSE
specific way. Therefore modpost failed to ignore the section.
The fix is to extend the pattern so we ignore all sections
that start with the name ".comment.".
