This reverts commit ba168fc3. It changes user-visible sysfs interfaces, and breaks some existing user space applications which apparently rely on the fact that the output does not contain the "0x" prefix.

This value interacts with some registers we don't currently know how to program properly ourselves. The default of 5 that we were using matches what the VBIOS on early DP cards do, but later ones use 6, which would cause nouveau to program an incorrect mode on these chips.

All indications seem to be that the version 0x30 table should be handled the same way as 0x40 (as used on G80), at least for the parts that we currently try use. This commit cleans up the parsing to make it clearer about what we're actually trying to achieve, and unifies the 0x30/0x40 parsing. Signed-off-by: NBen Skeggs <bskeggs@redhat.com>

I don't claim to understand the tty layer, but it seems like hvc_open and hvc_close should be balanced in their kref reference counting. Right now we get a kref every call to hvc_open: if (hp->count++ > 0) { tty_kref_get(tty); <----- here spin_unlock_irqrestore(&hp->lock, flags); hvc_kick(); return 0; } /* else count == 0 */ tty->driver_data = hp; hp->tty = tty_kref_get(tty); <------ or here if hp->count was 0 But hvc_close has: tty_kref_get(tty); if (--hp->count == 0) { ... /* Put the ref obtained in hvc_open() */ tty_kref_put(tty); ... } tty_kref_put(tty); Since the outside kref get/put balance we only do a single kref_put when count reaches 0. The patch below changes things to call tty_kref_put once for every hvc_close call, and with that my machine boots fine.

Commit 148f948b (vfs: Introduce new helpers for syncing after writing to O_SYNC file or IS_SYNC inode) broke the raw driver. We now call through generic_file_aio_write -> generic_write_sync -> vfs_fsync_range. vfs_fsync_range has: if (!fop || !fop->fsync) { ret = -EINVAL; goto out; } But drivers/char/raw.c doesn't set an fsync method. We have two options: fix it or remove the raw driver completely. I'm happy to do either, the fact this has been broken for so long suggests it is rarely used. The patch below adds an fsync method to the raw driver. My knowledge of the block layer is pretty sketchy so this could do with a once over. If we instead decide to remove the raw driver, this patch might still be useful as a backport to 2.6.33 and 2.6.32.

I hit this when we had a bug in IDR for a few days. Basically sysfs would fail to create new inodes since it uses an IDR and therefore class_create would fail.
