* [PARISC] Fix show_stack() when we can't kmallocMatthew Wilcox2007-02-17
| | | | | | | | | | | | | show_stack() was calling kzalloc() to allocate a struct pt_regs. This meant that *really* early stack dumps would cause a null pointer dereference. x86_64 allocates its pt_regs on the stack, so do the same. Kyle actually committed this exact patch to CVS on Wed Jul 26 14:32:39 2006 UTC, and never moved it across to git. Bad Kyle.

* [PARISC] Remove sched.h from uaccess.h on pariscMatthew Wilcox2007-02-17
| | | | | | | | | Al Viro did this for x86-64 and reduced the number of dependencies on sched.h significantly. We had a couple of files which were relying on uaccess.h pulling in sched.h, so they need explicit dependencies added.

| * [PATCH] PA-RISC: Fix bogus warnings from modpostMatthew Wilcox2007-02-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | parisc and parisc64 seem to name sections a little differently from other targets. parisc64 gives spurious warnings like: WARNING: drivers/net/dummy.o - Section mismatch: reference to .init.text:dummy_setup from .data.rel.ro between '.LC1' (at offset 0x0) and '.LC6' and parisc gives spurious warnings like: WARNING: drivers/net/dummy.o - Section mismatch: reference to .init.text:dummy_setup from .rodata.cst4 between '.LC1' (at offset 0x0) and '.LC6' Given the other comments in modpost.c, it seems that the best solution is to move rodata down to the 'match at start of name' section and add .data.rel.ro to the 'match entire name' section.

| * | [SCSI] sd: udev accessing an uninitialized scsi_disk field results in a crashNagendra Singh Tomar2007-02-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | sd_probe() calls class_device_add() even before initializing the sdkp->device variable. class_device_add() eventually results in the user mode udev program to be called. udev program can read the the allow_restart attribute of the newly created scsi device. This is resulting in a crash as the show function for allow_restart (i.e sd_show_allow_restart) returns the attribute value by reading the sdkp->device->allow_restart variable. As the sdkp->device is not initialized before calling the user mode hotplug helper, this results in a crash. The patch below solves it by calling class_device_add() only after the necessary fields in the scsi_disk structure are initialized properly.

According to the SCSI standards, the sense code is NO SENSE or RECOVERED ERROR in case writing filemark(s) succeeds. If it fails (partly or completely) the sense code is VOLUME OVERFLOW. The patch below is tested to fix the case when one filemark is successfully written after the EOM early warning. It should also fix the case at real EOM but this has not been tested.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The included patch fixes the following issues: 1. qla3xxx/qla4xxx co-existence issue which can result in a lockup when qla3xxx driver is unloaded, or when ifdown; ifup is performed on one of the interfaces correponding to qla3xxx. This is because qla4xxx HBA supports one ethernet and iscsi interfaces per port. Both iscsi and ethernet interfaces share the same state machine. The problem has to do with synchronizing access to the state machine in the event of a reset 2. mutex_lock() is sometimes not followed by mutex_unlock() prior to invoking a msleep() in qla4xxx_mailbox_command() Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
