2009-01-09ACPI : Use RSDT instead of XSDT by adding boot option of "acpi=rsdt"Zhao Yakui
On some boxes there exist both RSDT and XSDT table. But unfortunately sometimes there exists the following error when XSDT table is used: a. 32/64X address mismatch b. The 32/64X FACS address mismatch In such case the boot option of "acpi=rsdt" is provided so that RSDT is tried instead of XSDT table when the system can't work well. http://bugzilla.kernel.org/show_bug.cgi?id=8246 Signed-off-by: Zhao Yakui <yakui.zhao@intel.com> cc:Thomas Renninger <trenn@suse.de> Signed-off-by: Len Brown <len.brown@intel.com>
2009-01-09ACPI: Avoid array address overflow when _CST MWAIT hint bits are setZhao Yakui
The Cx Register address obtained from the _CST object is used as the MWAIT hints if the register type is FFixedHW. And it is used to check whether the Cx type is supported or not. On some boxes the following Cx state package is obtained from _CST object: >{ ResourceTemplate () { Register (FFixedHW, 0x01, // Bit Width 0x02, // Bit Offset 0x0000000000889759, // Address 0x03, // Access Size ) }, 0x03, 0xF5, 0x015E } In such case we should use the bit[7:4] of Cx address to check whether the Cx type is supported or not. mask the MWAIT hint to avoid array address overflow Signed-off-by: Zhao Yakui <yakui.zhao@intel.com> Acked-by:Venki Pallipadi <venkatesh.pallipadi@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>

2009-01-09[XFS] use scalable vmap APINick Piggin
Implement XFS's large buffer support with the new vmap APIs. See the vmap rewrite (db64fe02) for some numbers. The biggest improvement that comes from using the new APIs is avoiding the global KVA allocation lock on every call.

2009-01-09[XFS] remove old vmap cacheNick Piggin
XFS's vmap batching simply defers a number (up to 64) of vunmaps, and keeps track of them in a list. To purge the batch, it just goes through the list and calls vunamp on each one. This is pretty poor: a global TLB flush is generally still performed on each vunmap, with the most expensive parts of the operation being the broadcast IPIs and locking involved in the SMP callouts, and the locking involved in the vmap management -- none of these are avoided by just batching up the calls. I'm actually surprised it ever made much difference. (Now that the lazy vmap allocator is upstream, this description is not quite right, but the vunmap batching still doesn't seem to do much) Rip all this logic out of XFS completely. I will improve vmap performance and scalability directly in subsequent patch.

2009-01-09fujitsu-laptop: Simplify SBLL/SBL2 backlight handlingTony Vroon
GBLS and GBLL only differ in the clearing of the GHKS flag, so there is no need to have two backlight level readouts. Also, per Peter Gruber, the need for the BLNF check has disappeared. As a result, cleanups can be made in the code. This has been tested on the both the S6410 and the S6420 platforms and causes no functionality regressions, on the console without X or within X. One module parameter to disable the hotkeys is dropped, as we only ever took one codepath anyway.

2009-01-09fujitsu-laptop: Add BL power, LED control and radio state informationTony Vroon
The FUNC interface in the Fujitsu-Siemens DSDT was unused until now. It exposes state information that is now reported in additional platform files (whether the radios are killed by the hardware switch or operational, whether the machine is docked and whether the lid is open). Support for the backlight class is now extended with the ability to power the backlight on & off. Optional support for the LED class allows the keyboard headlamps found on the U810 netbook and the Fujitsu logo illumination on the P8010 notebook to be turned on & off. This was fed through checkpatch.pl and tested on the S6420, P8010 & U810 platforms.

2009-01-09[XFS] make xfs_ino_t an unsigned long longChristoph Hellwig
Currently xfs_ino_t is defined as a u64 which can either be an unsigned long long or on some 64 bit platforms and unsigned long. Just making it and unsigned long long mean's it's still always 64 bits wide, but we don't need to resort to cases to print it. Fixes a warning regression on 64 bit powerpc in current git.

2009-01-09[XFS] truncate readdir offsets to signed 32 bit valuesChristoph Hellwig
John Stanley reported EOVERFLOW errors in readdir from his self-build glibc. I traced this down to glibc enabling d_off overflow checks in one of the about five million different getdents implementations. In 2.6.28 Dave Woodhouse moved our readdir double buffering required for NFS4 readdirplus into nfsd and at that point we lost the capping of the directory offsets to 32 bit signed values. Johns glibc used getdents64 to even implement readdir for normal 32 bit offset dirents, and failed with EOVERFLOW only if this happens on the first dirent in a getdents call. I managed to come up with a testcase that uses raw getdents and does the EOVERFLOW check manually. We always hit it with our last entry due to the special end of directory marker. The patch below is a dumb version of just putting back the masking, to make sure we have the same behavior as in 2.6.27 and earlier. I will work on a better and cleaner fix for 2.6.30.

2009-01-09[XFS] pass XFS_IGET_BULKSTAT to xfs_iget for handle operationsChristoph Hellwig
NFS clients or users of the handle ioctls can pass us arbitrary inode numbers through the exportfs interface. Make sure we use the XFS_IGET_BULKSTAT so that these don't cause shutdowns due to the corruption checks. Also translate the EINVAL we get back for invalid inode clusters into an ESTALE which is more appropinquate, and remove the useless check for a NULL inode on a successfull xfs_iget return.

2009-01-09md: don't retry recovery of raid1 that fails due to error on source drive.NeilBrown
If a raid1 has only one working drive and it has a sector which gives an error on read, then an attempt to recover onto a spare will fail, but as the single remaining drive is not removed from the array, the recovery will be immediately re-attempted, resulting in an infinite recovery loop. So detect this situation and don't retry recovery once an error on the lone remaining drive is detected. Allow recovery to be retried once every time a spare is added in case the problem wasn't actually a media error. Signed-off-by: NeilBrown <neilb@suse.de>
