2008-05-30clean up atags exporting codeUwe Kleine-König
This gets rid of two static variables (one of them being __initdata) and a static function. Signed-off-by: Uwe Kleine-König <Uwe.Kleine-Koenig@digi.com> Acked-by: Uli Luckas <u.luckas@road.de>
2008-05-30There is no need to have BOOT_PARAMS_SIZE known outside of atags.cUwe Kleine-König
atags.c was the only user of KEXEC_BOOT_PARAMS_SIZE and kexec.h was only included to get that definition. Signed-off-by: Uwe Kleine-König <Uwe.Kleine-Koenig@digi.com> Acked-by: Uli Luckas <u.luckas@road.de>
2008-04-29proc: remove proc_root from driversAlexey Dobriyan
Remove proc_root export. Creation and removal works well if parent PDE is supplied as NULL -- it worked always that way. So, one useless export removed and consistency added, some drivers created PDEs with &proc_root as parent but removed them as NULL and so on.

2008-02-04[ARM] 4736/1: Export atags to userspace and allow kexec to use customised atagsRichard Purdie
Currently, the atags used by kexec are fixed to the ones originally used to boot the kernel. This is less than ideal as changing the commandline, initrd and other options would be a useful feature. This patch exports the atags used for the current kernel to userspace through an "atags" file in procfs. The presence of the file is controlled by its own Kconfig option and cleans up several ifdef blocks into a separate file. The tags for the new kernel are assumed to be at a fixed location before the kernel image itself. The location of the tags used to boot the original kernel is unimportant and no longer saved.
