This makes modpost handle MODULE_DEVICE_TABLE(dmi, xxxx).
I had to change the string pointers in the match table to char arrays,
and picked a size of 79 bytes almost at random -- do we need to make it
bigger than that? I was a bit concerned about the 'bloat' this
introduces into the match tables, but they should all be __initdata so
it shouldn't matter too much.(Actually, modpost does go through the relocations and look at most of
them; it wouldn't be impossible to make it handle string pointers -- but
doesn't seem to be worth the effort, since they're __initdata).Signed-off-by: David Woodhouse

The regexp used to match the start and the end of an initcall
are matching only on [a-zA-Z\_]. This rules out initcalls with
a number in them. This patch is fixing that.Signed-off-by: Arnaud Patard

David Sanders reported some issues with bootgraph.pl's display
of his sytems bootup; this commit fixes these by scaling the graph
not from 0 - end time but from the first initcall to the end time;
the minimum display size etc also now need to scale with this, as does
the axis display.Signed-off-by: Arjan van de Ven
-
When optimizing the kernel boot time, it's very valuable to visualize
what is going on at which time. In addition, with some of the initializing
going asynchronous soon, it's valuable to track/print which worker thread
is executing the initialization.This patch adds a script to turn a dmesg into a SVG graph (that can be
shown with tools such as InkScape, Gimp or Firefox) and a small change
to the initcall code to print the PID of the thread calling the initcall
(so that the script can work out the parallelism).Signed-off-by: Arjan van de Ven

Commit f072181e6403b0fe2e2aa800a005497b748fd284 ("kconfig: drop the
""trying to assign nonexistent symbol" warning") simply dropped the
warnings, but it does a little more than that, it also marks the current
.config as needed saving, so add this back.Signed-off-by: Roman Zippel
Signed-off-by: Linus Torvalds -
Recent changes to oldconfig have mixed up the silentoldconfig handling,
so this fixes that by clearly separating that special mode, e.g.
KCONFIG_NOSILENTUPDATE is only relevant here, the .config is written as
needed.This will also properly close Bug 11230.

In August 2006 I posted a patch generating a minimal SELinux policy. This
week, David P. Quigley posted an updated version of that as a patch against
the kernel. It also had nice logic for auto-installing the policy.Following is David's original patch intro (preserved especially
bc it has stats on the generated policies):se interested in the changes there were only two significant
changes. The first is that the iteration through the list of classes
used NULL as a sentinel value. The problem with this is that the
class_to_string array actually has NULL entries in its table as place
holders for the user space object classes.The second change was that it would seem at some point the initial sids
table was NULL terminated. This is no longer the case so that iteration
has to be done on array length instead of looking for NULL.Some statistics on the policy that it generates:
The policy consists of 523 lines which contain no blank lines. Of those
523 lines 453 of them are class, permission, and initial sid
definitions. These lines are usually little to no concern to the policy
developer since they will not be adding object classes or permissions.
Of the remaining 70 lines there is one type, one role, and one user
statement. The remaining lines are broken into three portions. The first
group are TE allow rules which make up 29 of the remaining lines, the
second is assignment of labels to the initial sids which consist of 27
lines, and file system labeling statements which are the remaining 11.In addition to the policy.conf generated there is a single file_contexts
file containing two lines which labels the entire system with base_t.This policy generates a policy.23 binary that is 7920 bytes.
(then a few versions later...):
The new policy is 587 lines (stripped of blank lines) with 476 of those
lines being the boilerplate that I mentioned last time. The remaining
111 lines have the 3 lines for type, user, and role, 70 lines for the
allow rules (one for each object class including user space object
classes), 27 lines to assign types to the initial sids, and 11 lines for
file system labeling. The policy binary is 9194 bytes.Changelog:
Aug 26: Added Documentation/SELinux.txt
Aug 26: Incorporated a set of comments by Stephen Smalley:
1. auto-setup SELINUXTYPE=dummy
2. don't auto-install if selinux is enabled with
non-dummy policy
3. don't re-compute policy version
4. /sbin/setfiles not /usr/sbin/setfiles
Aug 22: As per JMorris comments, made sure make distclean
cleans up the mdp directory.

created in the same file as the check, making it

Fix handling of nested structs or unions. The regex to strip (eliminate)
nested structs or unions was limited to only 0 or 1 matches. This can
cause an uneven number of left/right braces to be stripped, which causes

The extern flag currently is not included in type dump files

Signed-off-by: Sam Ravnborg -
We are having two kinds of problems with genksyms today: fake checksum
changes without actual ABI changes, and changes which we would rather like
to ignore (such as an additional field at the end of a structure that
modules are not supposed to touch, for example).I have thought about ways to improve genksyms and compute checksums
differently to avoid those problems, but in the end I don't see a
fundamentally better way. So here are some genksyms patches for at least
making the checksums more easily manageable, if we cannot fully fix them.In addition to the bugfixes (the first two patches), this allows genksyms
to track checksum changes and report why a checksum changed (third patch),
and to selectively ignore changes (fourth patch).This patch:
Gcc __attribute__ definitions may occur repeatedly, e.g.,
static int foo __attribute__((__used__))
__attribute__((aligned (16)));The genksyms parser does not understand this, and generates a syntax error.
Fix this case.Signed-off-by: Andreas Gruenbacher

make defconfig generated a lot of output
then noone actually read.
Use conf_set_all_new_symbols() to generate the default
configuration and avoid the chatty output.A typical run now looks like this:
$ make defconfig
*** Default configuration is based on 'i386_defconfig'
arch/x86/configs/i386_defconfig:13:warning: trying to assign nonexistent symbol SEMAPHORE_SLEEPERS

Previously when running "make oldconfig" we saw all the propmt lines
from kconfig and noone actully read this.With this patch the user will only see output if there is new symbols.
This will be seen as "make oldconfig" runs which does not generate any output.A typical run now looks like this:
$ make oldconfig
scripts/kconfig/conf -o arch/x86/Kconfig
$If a new symbol is found then we restart the config process like this:
