2005-05-22[PATCH] ppc64: Fix booting on latest G5 modelsBenjamin Herrenschmidt
The latest speedbumped Apple G5 models have a "bug" in the Open Firmware device tree that lacks the proper interrupt routing information for the northbridge i2c controller. Apple's driver silently falls back into a sub-optimal "polled" mode (heh, maybe they didn't even notice the bug because of that :), our driver didn't properly check and crashes :( This patch fixes our driver to not crash, and adds code to the prom_init() OF trampoline code that detects the "bug" and adds the missing information back for this chipset revision. This fixes booting and thermal control on these models. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

2005-04-24[PATCH] broken dependency for I2C_MPCAl Viro
All boards dealt with by I2C_MPC are 32bit. Moreover, driver simply won't build on ppc64 - it uses ppc32-only types all over the place. Dependency fixed - it's PPC32, not PPC. Signed-off-by: Al Viro <viro@parcelfarce.linux.theplanet.co.uk> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2005-04-18[PATCH] I2C: Fix incorrect sysfs file permissions in it87 and via686a driversJean Delvare
The it87 and via686a hardware monitoring drivers each create a sysfs file named "alarms" in R/W mode, while they should really create it in read-only mode. Since we don't provide a store function for these files, write attempts to these files will do something undefined (I guess) and bad (I am sure). My own try resulted in a locked terminal (where I attempted the write) and a 100% CPU load until next reboot. As a side note, wouldn't it make sense to check, when creating sysfs files, that readable files have a non-NULL show method, and writable files have a non-NULL store method? I know drivers are not supposed to do stupid things, but there is already a BUG_ON for several conditions in sysfs_create_file, so maybe we could add two more?

2005-04-18[PATCH] I2C: via686a cleanupsJean Delvare
Here comes a small cleanup patch for the via686a driver. I noticed the following two non-fatal problems: 1* The device parent is explicitely set, but it's not needed because the i2c core will do as the client is registered. 2* snprintf is used where strlcpy would suffice. Fixing them brings the via686a driver in line with what other similar drivers do. Signed-off-by: Jean Delvare <khali@linux-fr.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

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!
