I moved this a little too late - we need to run populate_rootfs() before running initcalls because some driver initcalls need to open files for firmware. The populate_rootfs() call is still coming after init_idle(), so it won't knock the scheduler over.

From: Christoph Hellwig <hch@lst.de> This one is a little funny. The SGI trees don't show this issue because dmapi and quota are separate modules so they must be unloaded before xfs_fs_exit can be called at all. So let's move the exitcalls for them in mainline first to simulate that behaviour.

From: Paul Mackerras <paulus@samba.org> This patch fixes a bug in the pmac-zilog driver where if you enable CRTSCTS mode, it won't output data when CTS is asserted. On powermacs, the CTS input is inverted. It also fixes a logic bug in testing for CTS and DCD changes.

They all have 128 bytes of ACPI/TCO IO space pointed to by config space register 0x40, and 64 bytes of GPIO space pointed to by 0x58. Thanks to Jun Nakajima for the full list.

read-write (re)mount is requested, empty $LogFile by overwriting it with 0xff bytes to ensure that Windows cannot cause data corruption by replaying a stale journal after Linux has written to the volume.

and force a read-only mount if not (fs/ntfs/super.c and fs/ntfs/logfile.c). This is a little bit of a crude check in that we only look at the restart areas and not at the actual log records so that there will be a very small number of cases where we think that a volume is dirty when in fact it is clean. This should only affect volumes that have not been shutdown cleanly and did not have any pending, non-check-pointed i/o.

This fixes a (very very small) preempt race window when we invalidate the IO permission bitmap on process exit.

There is a bug where if any process that obtained an IO access permissions via ioperm() does not explicitly "drop" that permissions, the IO permissions don't get properly invalidated on process exit. The cause is that exit_thread() only invalidates the per-thread io_bitmap pointer, but doesn't invalidate the per-TSS io_bitmap pointer as well. As the per-thread pointer is invalidated, __switch_to() doesn't take care of that one either, so the per-TSS pointer stays valid as long as some other process does ioperm(). This fixes the problem - it invalidates the per-TSS io_bitmap pointer and the problem goes away.

When Patrick removed ide_notify_reboot() in 2.5.42, he didn't notice that it meant that IDE no longer had any shutdown() functionality. So we did the right thing on suspend, but not on shutdown. ide_notify_reboot() was only doing STANDBY on shutdown (because FLUSH 'doesn't work' in 2.4 too) but it worked okay and we still should do STANDBY on shutdown because some broken disks flush their caches. Thus just calls bus->suspend() (FLUSH+STANDBY) at shutdown time. We can add some safety delay later - 2.4 doesn't have any.

There is a typo in the PTE freeing code causing us to possibly overflow the batch structure. Obvious fix (look at the closing parentheses).

I've updated the logips2pp driver to detect the MX310 and MX510 mice and also made it more maintainable by putting everything into one table instead of having 4 arrays for them (the MX700 support wasn't added correctly in the last revision).

This makes the idedisk_release function only flush the cache on final release; with the recent 2.6 blocklayer updates release gets called somewhat frequently, and at times where IO is outstanding to the disk. This bug didn't trigger before simply because ide_cacheflush_p() always was a nop.

This enables proper mxcsr register masking: the magic mask "0xffbf" is not necessarily correct for all CPU's, and there is an architected way to discover the proper MXCSR feature bits by examining the fxsave results. Please refer to IA32 Software Developer's Manual, Volume 1, Section 11.6.6 for more details.

ncpfs was forgetting to update iovec's iov_base field whenever partial transmission occured. This was causing data corruption during large (60kB) writes. The code now also passes copy of iovec to the sock_sendmsg, so it does not rely on network stack updating (or not updating) passed iovec in case of success (or failure).

I was going through the code looking for bits and pieces to pull across into the new LSI Logic beta megaraid driver /sys fs code and came across this one. LSI Logic have already fixed this issue for the 2.4 driver, and the new beta driver does not use the /proc filesystem at all, so no problem there. The problem is that resources are not freed upon certain error conditions in the in-kernel megaraid driver, to quote from Lester Hightower (who originally found the issue): "The problem occurs only in the circumstance where one reads one of the /proc/megaraid/hba<X>/diskdrives-ch<N> files where the card <X> does not have channel <N> on it. Most people would likely not notice this leak in normal operation, but due to the way that we monitor our MegaRaid cards in our company (we read these /proc entries every 180s) so we found the leak rather quickly, and unpleasantly (when your kernel eats all your RAM)." Anyway, here is the fix, compiled and tested OK for me.

This replaces some usages of sempahores on the stack with completions. We think we have had at least one bug report that could be caused by the inherent race in the semaphore usage.

There is an bug in bigsmp sub-architecture, due to which it will not enable all the CPUs when the BIOS-APICIDs are not 0 to n-1 (where n is total number of CPUs). Particularly, only 2 CPU comes up on a system that has 4 CPUs with BIOS APICID as (0, 1, 6, 7).=20 The bug is root caused to check_apicid_present(bit) call in smpboot.c, when bigsmp is expecting apicid in place of bit. check_apicid_present(bit) in bigsmp subarchitecture checks the bit with phys_id_present_map (which is actually map representing all apicids and not bit). One solution is to change check_apicid_present(bit) to check_apicid_present(apicid), in smp_boot_cpus(). But, it can affect all the other subarchitectures in various subtle ways. So, here is a simple alternate fix (Thanks to Martin Bligh), which solves the above problem. [ Confirmation from Martin: Looks fine, it's exactly the same fix we use for Summit. Since we're using the other method instead of the bitmap, this check isn't needed, so we can just bypass it. This way also has the great advantage of being isolated to the bigsmp subarch, so it only needs testing there ;-) ]

From: <mikem@beardog.cca.cpqcorp.net> This patch adds support for 2 new controllers. The first is a PCI-Express version of the 6400. The second is actually a SATA controller using the cciss interface.

Based on information provided by "Allen Martin" <AMartin@nvidia.com>: A hang is caused when the CPU generates a very fast CONNECT/HALT cycle sequence. Workaround is to set the SYSTEM_IDLE_TIMEOUT to 80 ns. This allows the state-machine and timer to return to a proper state within 80 ns of the CONNECT and probe appearing together. Since the CPU will not issue another HALT within 80 ns of the initial HALT, the failure condition is avoided.
