The 'unplug on queued exceeding unplug threshold' logic only works for file system requests currently, since it's in __make_request(). Move it where it belongs, in elv_add_request(). This way it works for queued block sg requests as well. Signed-Off-By:

This patch provides a conversion routine for 32-bit user space apps that call into a 64-bit kernel on x86_64 architectures. This is required for the HP Array Configuration utility and the HP management agents. Without this patch the apps will not function. The 2 ioctls affected are the cciss pass thru ioctls. Caveat: it spits out 2 warnings during compilation. I've tried everything I can think of to clean them up, but... If anyone has any helpful suggestions I'm all ears.

Due to different structure alignment rules in the ABI between ia32 and ia64, certain members of the dirent structure are not guaranteed to be 8 byte aligned on ia64. This requires a compat wrapper around these 32 bit system calls. Other architectures may or may not have the problem, depending on the alignment rules. This was observed by running /emul/ia32-linux/bin/ls on 2.6.6 which produces kernel mode unaligned faults. Original patch by: Arnd Bergmann <arnd@arndb.de> Signed-off-by:

- "\<" and "\>" can be safely replaced with "<" and ">" - "$var =~ /^string$/" is better written "$var eq 'string'" - $i is better written without the double quotes - it's not safe to use for without "my"ing the iteration variable - "print foreach @array" is better written "print @array" - declare variables - ".*" is useless at the end of a regexp - "$a[@A] = $foo" is a rather obfuscated syntax for "push @A, $foo"... let's not opencoding language basic operators... - ignoring return value from a regexp is very bad: this can results in working on previous value of $1, $2, ...

This file provides ability for caller of register_cpu() to either create a control file, or not. This can be handy if a particular platform decides that certain CPU's are not removable. Hence would like to not create a control file. Signed-off-by:

Suggested by Manfred Spraul. __get_free_pages had a hack to do node interleaving allocation at boot time. This patch sets an interleave process policy using the NUMA API for init and the idle threads instead. Before entering the user space init the policy is reset to default again. Result is the same. Advantage is less code and removing of a check from a fast path. Removes more code than it adds. I verified that the memory distribution after boot is roughly the same. Signed-off-by:

While sweeping the APIC code two points were missed. The first is getting the definition of BAD_APICID available to include/asm-i386/mach-default/mach_apic.h by #including the right header, and the second is UP local APIC without UP IO-APIC linking in get_broadcast_physid(). Signed-off-by:

Marking invalid APIC ID's in phys_cpu_present_map was intended to generate "collisions" between APIC ID's in order to assist the ordinary bounds checking against the broadcast physical APIC ID. However, this is bounds checked everywhere it's necessary, and it's also not even possible to properly bounds-check everywhere. So this patch removes that marking of non-present physical APIC ID's.

The following patch repairs kicking of non-present cpus by making cpu_present_to_apicid() bounds-check its argument. It also corrects the same issue on NUMA-Q by correctly passing the generated artificial APIC ID instead of the raw value discovered in the MP table. A miscellaneous compilefix for CONFIG_ACPI_BOOT is also included for completeness. Signed-off-by:

The following patch appears sound according to an audit to ensure that all of the codepaths where it was introduced were called after the APIC fixmappings were set up. This patch introduces get_physical_broadcast(), which checks the version ID of the local APIC to determine whether it's a serial APIC or xAPIC, and returns the correct physical broadcast ID. It replaces all uses of APIC_BROADCAST_ID and IO_APIC_MAX_ID with this in order to ensure. It also changes the checks during MP table parsing so the APIC ID is checked in tandem with the version number. I'm holding out for some kind of testing to get an idea of whether this covers the cases or introduces regressions, or whatever. Signed-off-by:

The following patch adds support for the 3Com networking core found in the ATI Radeon 9100 IGP southbridge used on boards like Asus P4R800-VM. The main point of this patch is using HAS_MII instead of HAS_NWAY for the definition of the board. All the previous trials since the end of last year used HAS_NWAY which disables the Tx part of the transceiver; using HAS_NWAY was the way all 3Com Cyclone and Tornado chips worked, as they had the transceiver integrated. The ATI solution has an external transceiver and I had to physically see the different chip on the board (the board was provided by ATI) to finally understand that it needs the HAS_MII definition... I'm still waiting for some docs from ATI to clarify if this is the correct way of handling this chip and if there are any differences w.r.t EEPROM handling, but as it appears to work and was also confirmed by other testers, I don't want to keep owners of such boards away from their networks :-) The textual identification was a bit hard to decide; it's called "3c920B-EMB-WNM" in the Windows .INF file that Asus provides for their boards. As this name was already used for PCI ID 9210, I added the paranthesis which specifies where this chip is found. The Scyld driver defines FEATURE_TORNADO to include HAS_NWAY. This board would then probably need to not be defined with FEATURE_TORNADO, but the same as in this patch. I would like to publicly thank Tyson Vickers for both ideas and patience during the last few weeks. He managed to get the driver working by randomly setting driver parameters :-) But then he contacted me and worked with me towards the solution. Signed-off-by:

attached is an update for the sisfb driver to version 1.7.10. This update includes - fixes for pure 64bit and 32/64bit mixed systems (add ioctl conversion; fix variable sizes, etc; REQUIRED for current X.org/XFree86 on 64bit systems, even if pure 64bit), - fixes for 301C video bridge, (scales TV output correctly now) - fixes for 1600x1200 and 1400x1050 LCD panels, - many fixes for 661/741/760 (amongst others, proper LFB support for the 760 and corrections for SiS' new BIOS data layout; would lead to display corruption with old driver) - add support for many modes for LCD which were unsupported previously, - add support for HiVision and YPbPr HDTV - "vga=" statement now honoured properly (sisfb will set the same mode as the kernel did by default) - use LCD native resolution mode if no mode is given - a major clean up of main driver code, - radical removal of duplicate (or nearly duplicate) code, - switched to 2.6 module_param macros, - enhanced communication with the X driver, - added eventual POSTing of SiS300/305 card for non-x86 archs, - added ability to relocate the image on the TV screen using a userland tool, - added Documentation/fb/sisfb.txt (why the heck was this missing?!) - small fix for SiS DRM driver (match 32/64bit fixes mentioned above) (cast the data passed to sis_free as u32) - make driver re-entrant by avoiding static structures and variables. As usual, heavily tested. The mode switching code is even lab-tested by SiS (although 100% written by me). Please apply asap (especially since 64bit systems were not properly supported previously; as mentioned, current X.org/XFree86 needs this update for proper communication with the framebuffer driver on 64bit systems. X crashes on such systems with the old driver). Signed-off-by:

Paul Serice authored
This is my fourth attempt to patch the isofs code. It is similar to the last posting except this one implements the NFS get_parent() method which has always been missing. The original problem I set out to addresses is that the current iso9660 file system cannot reach inodes located beyond the 4GB barrier. This is caused by using the inode number as the byte offset of the inode data. Being 32-bits wide, the inode number is unable to reach inode data that does not reside on the first 4GB of the file system. This causes real problems with "growisofs" http://fy.chalmers.se/~appro/linux/DVD+RW/#isofs4gb and my pet project "shunt" http://www.serice.net/shunt/ This patch switches the isofs code from iget() to iget5_locked() which allows extra data to be passed into isofs_read_inode() so that inode data anywhere on the disk can be reached. The inode number scheme was also changed. Continuing to use the byte offset would have resulted in non-unique inodes in many common situations, but because the inode number no longer plays any role in reading the meta-data off the disk, I was free to set the inode number to some unique characteristic of the file. I have chosen to use the block offset which is also 32-bits wide. Lastly, the pre-patch code uses the default export_operations to handle accessing the file system through NFS. The problem with this is that the default NFS operations assume that iget() works which is no longer the case because of the necessity of switching to iget5_locked(). So, I had to implement the NFS operations too. As a bonus, I went ahead and implemented the NFS get_parent() method which has always been missing. Signed-off-by:
