2008-02-14moduleparam: fix alpha, ia64 and ppc64 compile failuresIvan Kokshaysky1-1/+11
On alpha, ia64 and ppc64 only relocations to local data can go into read-only sections. The vast majority of module parameters use the global generic param_set_*/param_get_* functions, so the 'const' attribute for struct kernel_param is not only useless, but it also causes compile failures due to 'section type conflict' in those rare cases where param_set/get are local functions.

2006-12-07[PATCH] Compile-time check re world-writeable module paramsAlexey Dobriyan1-0/+3
One of the mistakes a module_param() user can make is to supply default value of module parameter as the last argument. module_param() accepts permissions instead. If default value is, say, 3 (-------wx), parameter becomes world-writeable. So far, the only remedy was to apply grep(1) and read drivers submitted to -mm. BTDT. With this patch applied, compiler will finally do some job. *) bounds checking on permissions *) world-writeable bit checking on permissions *) compile breakage if checks trigger First version of this check (only "& 2" part) directly caught 4 out of 7 places during my last grep.

2006-01-06kbuild: un-stringnify KBUILD_MODNAMESam Ravnborg1-1/+1
Now when kbuild passes KBUILD_MODNAME with "" do not __stringify it when used. Remove __stringnify for all users. This also fixes the output of: $ ls -l /sys/module/ drwxr-xr-x 4 root root 0 2006-01-05 14:24 pcmcia drwxr-xr-x 4 root root 0 2006-01-05 14:24 pcmcia_core drwxr-xr-x 3 root root 0 2006-01-05 14:24 "processor" drwxr-xr-x 3 root root 0 2006-01-05 14:24 "psmouse" The quoting of the module names will be gone again. Thanks to GregKH + Kay Sievers for reproting this. Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
2005-04-17Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds1-0/+182
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
