* tty: Ldisc revampAlan Cox2008-07-20
| | | | | | | | | | | | Move the line disciplines towards a conventional ->ops arrangement. For the moment the actual 'tty_ldisc' struct in the tty is kept as part of the tty struct but this can then be changed if it turns out that when it all settles down we want to refcount ldiscs separately to the tty. Pull the ldisc code out of /proc and put it with our ldisc code. Signed-off-by: Alan Cox <alan@redhat.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

* Subject: [PATCH 1/2] serial: Add flush_buffer() operation to uart_opsHaavard Skinnemoen2008-07-20
| | | | | | | | | | | | | | | | | Serial drivers using DMA (like the atmel_serial driver) tend to get very confused when the xmit buffer is flushed and nobody told them. They also tend to spew a lot of garbage since the DMA engine keeps running after the buffer is flushed and possibly refilled with unrelated data. This patch adds a new flush_buffer operation to the uart_ops struct, along with a call to it from uart_flush_buffer() right after the xmit buffer has been cleared. The driver can implement this in order to syncronize its internal DMA state with the xmit buffer when the buffer is flushed.

| * configfs: Allow ->make_item() and ->make_group() to return detailed errors.Joel Becker2008-07-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The configfs operations ->make_item() and ->make_group() currently return a new item/group. A return of NULL signifies an error. Because of this, -ENOMEM is the only return code bubbled up the stack. Multiple folks have requested the ability to return specific error codes when these operations fail. This patch adds that ability by changing the ->make_item/group() ops to return an int. Also updated are the in-kernel users of configfs. Signed-off-by: Joel Becker <joel.becker@oracle.com>

However, it is installed at (2) before initializing controller specific slot data structure at (4). Because of this, pciehp driver cannot handle the following cases properly. - If devices that shares IRQ with pciehp raise interrupts between (2) and (4). - If hotplug events (e.g. MRL open) happen between (3) and (4). We already have a workaround for this problem ("pciehp: fix NULL dereference in interrupt handler: dbd79aed1aea2bece0bf43cc2ff3b2f9baf48a08). But we still need fundamental fix.

I converted pr_debug() to dev_dbg(). Both use KERN_DEBUG and are enabled only when DEBUG is defined. I converted printk(KERN_DEBUG) to dev_printk(KERN_DEBUG), not to dev_dbg(), because dev_dbg() is only enabled when DEBUG is defined. I converted DBG(KERN_INFO) (only in setup-bus.c) to dev_info(). The DBG() name makes it sound like debug, but it's been enabled forever, so dev_info() preserves the previous behavior. I tried to make the resource assignment formats more consistent, e.g., "BAR %d: got res [%#llx-%#llx] bus [%#llx-%#llx] flags %#lx\n" instead of sometimes using "start-end" and sometimes using "size@start". I'm not attached to one or the other; I'd just like them consistent. Signed-off-by: Bjorn Helgaas <bjorn.helgaas@hp.com> Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org>

Provide a workaround for these systems allowing them to pass 'acpi_sleep=old_ordering' in the kernel command line so that it will use the pre-ACPI 2.0 ("old") suspend code ordering. Unfortunately, this requires us to add a platform hook to the resuming of devices for recovering the platform in case one of the device drivers' .suspend() routines returns error code. Namely, ACPI 1.0 specifies that _PTS should be called before suspending devices, but _WAK still should be called before resuming them in order to undo the changes made by _PTS. However, if there is an error during suspending devices, they are automatically resumed without returning control to the PM core, so the _WAK has to be called from within device_resume() in that cases. The patch also reorders and refactors the ACPI suspend/hibernation code to avoid duplication as far as reasonably possible. Signed-off-by: Rafael J.
