We weren't using the recommended sequence for putting the CPU into nap mode. When I changed the idle loop, for some reason 7447A cpus started hanging when we put them into nap mode. Changing to the recommended sequence fixes that. The complexity here is that the recommended sequence is a loop that keeps putting the cpu back into nap mode. Clearly we need some way to break out of the loop when an interrupt (external interrupt, decrementer, performance monitor) occurs. Here we use a bit in the thread_info struct to indicate that we need this, and the exception entry code notices this and arranges for the exception to return to the value in the link register, thus breaking out of the loop. We use a new `local_flags' field in the thread_info which we can alter without needing to use an atomic update sequence. The PPC970 has the same recommended sequence, so we do the same thing there too. This also fixes a bug in the kernel stack overflow handling code on 32-bit, since it was causing a value that we needed in a register to get trashed. Signed-off-by: NPaul Mackerras <paulus@samba.org>

Somehow in the midst of dotting i's and crossing t's during the merge up to rc1 we wound up keeping __put_task_struct_cb when it should have been killed as it no longer has any users.

The naming of the constant defined for PCI ID 1022:7450 does not seem to match the information at http://pciids.sourceforge.net/: http://pci-ids.ucw.cz/iii/?i=1022 There 1022:7450 is listed as "AMD-8131 PCI-X Bridge" while 1022:7451 is listed as "AMD-8131 PCI-X IOAPIC". Yet, the current definition for 0x7450 is PCI_DEVICE_ID_AMD_8131_APIC. It seems to me like that name should map to 0x7451, while a name like PCI_DEVICE_ID_AMD_8131_BRIDGE should map to 0x7450.

[BLOCK] delay all uevents until partition table is scanned Here we delay the annoucement of all block device events until the disk's partition table is scanned and all partition devices are already created and sysfs is populated. We have a bunch of old bugs for removable storage handling where we probe successfully for a filesystem on the raw disk, but at the same time the kernel recognizes a partition table and creates partition devices. Currently there is no sane way to tell if partitions will show up or not at the time the disk device is announced to userspace. With the delayed events we can simply skip any probe for a filesystem on the raw disk when we find already present partitions.

It works like this: Open the file Read all the contents. Call poll requesting POLLERR or POLLPRI (so select/exceptfds works) When poll returns, close the file and go to top of loop. or lseek to start of file and go back to the 'read'. Events are signaled by an object manager calling sysfs_notify(kobj, dir, attr); If the dir is non-NULL, it is used to find a subdirectory which contains the attribute (presumably created by sysfs_create_group). This has a cost of one int per attribute, one wait_queuehead per kobject, one int per open file. The name "sysfs_notify" may be confused with the inotify functionality. Maybe it would be nice to support inotify for sysfs attributes as well? This patch also uses sysfs_notify to allow /sys/block/md*/md/sync_action to be pollable Signed-off-by: NNeil Brown <neilb@suse.de> Signed-off-by: NGreg Kroah-Hartman <gregkh@suse.de>

As previously reported via Michael Reed, the FC transport took a hit in 2.6.15 (perhaps a little earlier) when we solved a recursion error. There are 2 deadlocks occurring: - With scan and the delete items sharing the same workq, flushing the workq for the delete code was getting it stalled behind a very long running scan code path. - There's a deadlock where scsi_remove_target() has to sit behind scsi_scan_target() due to contention over the scan_lock(). This patch resolves the 1st deadlock and significantly reduces the odds of the second. So far, we have only replicated the 2nd deadlock on a highly-parallel SMP system. More on the 2nd deadlock in a following email. This patch reworks the transport to: - Only use the scsi host workq for scanning - Use 2 other workq's internally. One for deletions, the other for scheduled deletions. Originally, we tried this with a single workq, but the occassional flushes of the scheduled queues was hitting the second deadlock with a slightly higher frequency. In the future, we'll look at the LLDD's and the transport to see if we can get rid of this extra overhead. - When moving to the other workq's we tightened up some object states and some lock handling. - Properly syncs adds/deletes - minor code cleanups - directly reference fc_host_attrs, rather than through attribute macros - flush the right workq on delayed work cancel failures. Large kudos to Michael Reed who has been working this issue for the last month. Signed-off-by: NJames Bottomley <James.Bottomley@SteelEye.com>

Original From: Ingo Flaschberger <if@xip.at> To support the RA4100 array from Compaq. This patch now correctly handles SCSI_UNKNOWN types with regard to BLIST_REPORTLUNS2 (allow it) and cdb[1] LUN inclusion (don't). It also allows a BLIST_MAX_512 flag to restrict the maximum transfer length to 512 blocks (apparently this is an RA4100 problem). Signed-off-by: NJames Bottomley <James.Bottomley@SteelEye.com>

We currently have two implementations of this obsolete ioctl, one in the block layer and one in the scsi code. Both of them have drawbacks. This patch kills the scsi layer version after updating the block version with the missing bits: - argument checking - use scatterlist I/O - set number of retries based on the submitted command This is the last user of non-S/G I/O except for the gdth driver, so getting this in ASAP and through the scsi tree would be nie to kill the non-S/G I/O path. Jens, what do you think about adding a check for non-S/G I/O in the midlayer? Thanks to Or Gerlitz for testing this patch.

Basically an in-kernel implementation of tee, which uses splice and the pipe buffers as an intelligent way to pass data around by reference. Where the user space tee consumes the input and produces a stdout and file output, this syscall merely duplicates the data inside a pipe to another pipe. No data is copied, the output just grabs a reference to the input pipe data. Signed-off-by: NJens Axboe <axboe@suse.de>

The driver has 2 methods for setting the color map, using the protected mode interface provided by the video BIOS and directly writing to the VGA registers. The former is not supported in x86_64 and the latter is enabled only in i386. Fix by enabling the latter method in x86_64 only if supported by the BIOS.

Every caller of svc_take_page ignores its return value and assumes it succeeded. So just WARN() instead of returning an ignored error. This would have saved some time debugging a recent nfsd4 problem. If there are still failure cases here, then the result is probably that we overwrite an earlier part of the reply while xdr-encoding. While the corrupted reply is a nasty bug, it would be worse to panic here and create the possibility of a remote DOS; hence WARN() instead of BUG(). Signed-off-by: NJ.

An UML user reported (against 2.6.13.3/UML) he got kernel Oopses when trying to rmmod (on a kernel with module unloading enabled) a module compiled with module unloading disabled. As crashing is a very correct thing to do in that case, a solution is altering the vermagic string to include this too. Possibly, however, the code should not crash in this case, even if the module didn't support unloading - it should simply abort the module removal. In this case, fixing that bug would be a better solution. I've not investigated though. (akpm: a bit marginal - root screwed up and shot himself in the foot).
