In the lead up to 2.6.13 I fixed a large number of reboot problems by making the calling conventions consistent. Despite checking and double checking my work it appears I missed an obvious one. The S4 suspend code for PM_DISK_PLATFORM was also calling device_shutdown without setting system_state, and was not calling the appropriate reboot_notifier. This patch fixes the bug by replacing the call of device_suspend with kernel_poweroff_prepare. Various forms of this failure have been fixed and tracked for a while. Thanks for tracking this down go to: Alexey Starikovskiy, Meelis Roos <mroos@linux.ee>, Nigel Cunningham <ncunningham@cyclades.com>, Pierre Ossman <drzeus-list@drzeus.cx> History of this bug is at: http://bugme.osdl.org/show_bug.cgi?id=4320Signed-off-by:

In the lead up to 2.6.13 I fixed a large number of reboot problems by making the calling conventions consistent. Despite checking and double checking my work it appears I missed an obvious one. This first patch simply refactors the reboot routines so all of the preparation for various kinds of reboots are in their own functions. Making it very hard to get the various kinds of reboot out of sync. Signed-off-by:

Wire the MCA/INIT handler stacks into DTR[2] and track them in IA64_KR(CURRENT_STACK). This gives the MCA/INIT handler stacks the same TLB status as normal kernel stacks. Reload the old CURRENT_STACK data on return from OS to SAL. Signed-off-by:

The sd driver now uses scsi_execute_req() for almost everything. scsi_execute_req() converts requests into scatterlists. Fix the HP SCSI disk simulator to understand scatterlists for more commands. Without this patch the current kernel will not boot on the simulator (the disks are always detected as having no sectors, and so cannot be mounted). Signed-off-by:

Addresses some small bugs in the pegasus ethernet-over-USB driver. Specifically, malformed long packets from the adapter could cause a kernel panic; the interrupt interval calculation was inappropriate for high-speed devices; the return code from read_mii_word was tested incorrectly; and failure to unlink outstanding URBs before freeing them could lead to kernel panics when unloading the driver.

Three minor sl811-hcd fixes: - Elminate memory leak on one (rare) disable/shutdown path. - For periodic transfers that don't need to be scheduled, update urb->start_frame to represent the transfer phase correctly. - Report the (single) port as removable, by default. Since no drivers yet use start_frame or that part of the hub descriptor, only that leak is likely to ever matter. Signed-off-by:

I'm using a 2 port USB RS232 dongle to connect to a serial-IR cradle for a bar code reader). Detecting the baudrate of the serial-IR involves keeping DTR low while changing baudrate. This works using normal 16550A serial ports as well as the FTDI driver version 1.4.0 (Linux 2.6.8) but stopped working with the change to "ensure RTS and DTR are raised when changing baudrate" introduced in version 1.4.1 (Linux 2.6.9). The attached patch fixes this, so RTS and DTR is only raised when changing baudrate iff the previous baudrate was B0. Signed-off-by:

This function expects an unsigned 32-bit type as its third argument: static u32 pci_size(u32 base, u32 maxbase, u32 mask) However, given these definitions: #define PCI_BASE_ADDRESS_MEM_MASK (~0x0fUL) #define PCI_ROM_ADDRESS_MASK (~0x7ffUL) these two calls in drivers/pci/probe.c are problematic for architectures for which a UL is not equivalent to a u32: sz = pci_size(l, sz, PCI_BASE_ADDRESS_MEM_MASK); sz = pci_size(l, sz, PCI_ROM_ADDRESS_MASK); Hence the below compile warning when building for ARCH=ppc64: drivers/pci/probe.c: In function `pci_read_bases': /.../probe.c:168: warning: large integer implicitly truncated to unsigned type /.../probe.c:218: warning: large integer implicitly truncated to unsigned type Here is a simple fix.

The class symlinks in sysfs don't properly handle changing device names. To demonstrate, rename your network device from eth0 to eth1. Your pci (or usb, or whatever) device will still have a 'net:eth0' link, except now it points to /sys/class/net/eth1. The attached patch makes sure the class symlink name changes when the class device name changes. It isn't 100% correct, it should be using sysfs_rename_link. Unfortunately, sysfs_rename_link doesn't exist. Signed-off-by:

bus_rescan_devices_helper() does not hold the dev->sem when it checks for !dev->driver(). device_attach() holds the sem, but calls again device_bind_driver() even when dev->driver is set. What happens is that a first device_attach() call (module insertion time) is on the way binding the device to a driver. Another thread calls bus_rescan_devices(). Now when bus_rescan_devices_helper() checks for dev->driver it is still NULL 'cos the the prior device_attach() is not yet finished. But as soon as the first one releases the dev->sem the second device_attach() tries to rebind the already bound device again. device_bind_driver() does this blindly which leads to a corrupt driver->klist_devices list (the device links itself, the head points to the device). Later a call to device_release_driver() sets dev->driver to NULL and breaks the link it has to itself on knode_driver. Rmmoding the driver later calls driver_detach() which leads to an endless loop 'cos the list head in klist_devices still points to the device. And since dev->driver is NULL it's stuck with the same device forever. Boom. And rmmod hangs. Very easy to reproduce with new-style pcmcia and a 16bit card. Just loop modprobe <pcmcia-modules> ;cardctl eject; rmmod <card driver, pcmcia modules>. Easiest fix is to check if the device is already bound to a driver in device_bind_driver(). This avoids the double binding. Signed-off-by:

The header declaring this function wasn't included, so the function declaration was totally bogus wrt. the proto - even if this wasn't going to fail at all. It was so bad that the compile warning I got was "control reaches end of non-void function", i.e. missing return. Actually, this has been there for ages, the consolidation patch just added the warning which was needed to clean it up. Nice. Really. Cc: Allan Graves <allan.graves@gmail.com> Signed-off-by:

Even if with a bit of misunderstanding, Al fixed this in commit 95608261. Well, the symbol was intended to come from userspace (it exists there on normal host), but since some hosts may miss that, using the kernel one is just as fine. However, rename it to be named consistently with the rest. Actually, he missed converting ELFCLASS32 to coming from kernel headers. For consistence, add ELFCLASS64 too.

I am a lamer :-(. Luckily, Luo Xin performed LTP testing and found this failure. Btw, the fact that the patch in which I introduced this was merged shows that: a) I'm really trusted by people b) sometimes they're wrong about point a). c) lack of time for reviewers.

As recently done by Russell King for ARM, commit 4732efbe introduces a generic asm/futex.h copied along most arches, which includes a "-ENOSYS support" to be changed if needed. However, it includes an unused var (taken from the "real" version) which GCC warns about. Remove it from all arches having that file version (i.e. same GIT id). $ git-diff-tree -r HEAD and $ git-ls-tree -r HEAD include/|grep 9feff4ce1424bc390608326240be369eb13aa648 may be more interesting than looking at the patch itself, to make sure I've just copied the arm header to all other archs having the original dummy version of this file.

Follow up to 4732efbe - uml must just reuse as-is the backing architecture support. There is a micro-fixup is needed for the included file, which won't affect i386 behaviour at all. I've not tested compilation on x86_64, only on x86, but the code is almost the same except the culprit test, so everything should be ok on x86_64 too.
