* sysfs: kill unnecessary attribute->ownerTejun Heo2007-07-11
| | | | | | | | | | | | | | | | | | | | | | | | | | sysfs is now completely out of driver/module lifetime game. After deletion, a sysfs node doesn't access anything outside sysfs proper, so there's no reason to hold onto the attribute owners. Note that often the wrong modules were accounted for as owners leading to accessing removed modules. This patch kills now unnecessary attribute->owner. Note that with this change, userland holding a sysfs node does not prevent the backing module from being unloaded. For more info regarding lifetime rule cleanup, please read the following message. http://article.gmane.org/gmane.linux.kernel/510293 (tweaked by Greg to not delete the field just yet, to make it easier to merge things properly.)

| * [MIPS] PNX8550: Cleanup proc code.Robert P. J. Day2007-07-10
| | | | | | | | | | | | | | | | | | Here's a slightly cleaner way of creating the /proc structure for the pnx8850. mostly, it creates a directory with default mode 555, since the one you're creating is mode 444, which is somewhat unusual for a directory under /proc.

| * [MIPS] DECstation: Optimised early printk()Maciej W. Rozycki2007-07-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is an optimised implementation of early printk() for the DECstation. After the recent conversion to a MIPS-specific generic routine using a character-by-character output the performance dropped significantly. This change reverts to the previous speed -- even at 9600 bps of the serial console the difference is visible with a naked eye; I presume for a framebuffer it is even worse (it may depend on exactly which one is used though). Additionally the change includes a fix for a problem that the old implementation had -- the format used would not actually limit the length of the string output. This new implementation uses a local buffer to deal with it -- even with this additional copying it is much faster than the generic function. Plus this driver is registered much earlier than the generic one, allowing one to see critical messages, such as one about an incorrect CPU setting used, that are produced beforehand. :-) Signed-off-by: Maciej W.
