The address passed to io_remap_pfn_range() in hpet_mmap() does not need to be converted using __pa(): it is already a physical address. This bug was found and the patch suggested by Clay Harris. I introduced this particular bug when making io_remap_pfn_range changes a few months ago. In fact mmap()ing /dev/hpet has *never* previously worked: before my changes __pa() was being executed on an ioremap()ed virtual address, which is also invalid. Signed-off-by:

It is essential that index_of() be inlined. But alpha undoes the gcc inlining hackery and index_of() ends up out-of-line. So fiddle with things to make that function inline again. Cc: Richard Henderson <rth@twiddle.net> Signed-off-by:

Current -git tree doesn't build when enabling oprofile on a non-bookE CPU (like on a PowerMac for example). While there is no performance counter support for these CPUs implemented yet, it's still nice to be able to use the timer based sampling, and that got broken. Signed-off-by:

If error occurs while in v9fs_get_sb after it calles sget, the dentry object of the root and its inode may be freed twice -- once while handling the error in v9fs_get_sb, and second time when v9fs_get_sb calles deactivate_super (which in turn calls v9fs_kill_super) The patch removes the unnecessary code that frees the root dentry and its inode.

v9fs_vfs_readlink allocates space for the link using __getname and errorneously uses strlen on the newly allocated buffer to check if the buffer passed by the user is bigger than the one returned by __getname. The patch replaces the strlen usage to PATH_MAX, which is the actual size of the buffers returned by __getname. Signed-off-by:

When a new session is created it uses a template object of the specified transport type to instantiate its own copy. The code for the making a copy of the template object was lost, and the object itself is attached to the v9fs session. This leads to many sessions using the same transport instead of having their own copy. The patch puts back the code that makes a copy of the template object. Signed-off-by:

buf_check_size function checks if the conv buffer has enough space for the performed operation, but it doesn't return the result back to the calling function, only logs an error in the log. The report-back-error functionality was lost when buf_check_size was converted from macro to inline function. The return in the macro used to exit from the functions that include it, after the conversion it just exits from the inline function itself. The patch makes buf_check_size to return flag and all functions that use it check if they should perform the operation, or exit. Signed-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. 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:

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:
