2006-09-27[PATCH] EISA bus MODALIAS attributes supportMichael Tokarev
Add modalias attribute support for the almost forgotten now EISA bus and (at least some) EISA-aware modules. The modalias entry looks like (for an 3c509 NIC): eisa:sTCM5093 and the in-module alias like: eisa:sTCM5093* The patch moves struct eisa_device_id declaration from include/linux/eisa.h to include/linux/mod_devicetable.h (so that the former now #includes the latter), adds proper MODULE_DEVICE_TABLE(eisa, ...) statements for all drivers with EISA IDs I found (some drivers already have that DEVICE_TABLE declared), and adds recognision of __mod_eisa_device_table to scripts/mod/file2alias.c so that proper modules.alias will be generated. There's no support for /lib/modules/$kver/modules.eisamap, as it's not used by any existing tools, and because with in-kernel modalias mechanism those maps are obsolete anyway. The rationale for this patch is: a) to make EISA bus to act as other busses with modalias support, to unify driver loading b) to foget about EISA finally - with this patch, kernel (who still supports EISA) will be the only one who knows how to choose the necessary drivers for this bus ;) [akpm@osdl.org: fix the kbuild bit] Signed-off-by: Michael Tokarev <mjt@tls.msk.ru> Cc: Rusty Russell <rusty@rustcorp.com.au> Cc: Randy Dunlap <rdunlap@xenotime.net> Acked-the-net-bits-by: Jeff Garzik <jeff@garzik.org> Acked-the-tulip-bit-by: Valerie Henson <val_henson@linux.intel.com> Cc: James Bottomley <James.Bottomley@steeleye.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2006-09-27[PATCH] x86 microcode: using request_firmware to pull microcodeShaohua Li
Using request_firmware to pull ucode from userspace, so we don't need the application 'microcode_ctl' to assist. We name each ucode file according to CPU's info as intel-ucode/family-model-stepping. In this way we could split ucode file as small one. This has a lot of advantages such as selectively update and validate microcode for specific models, better manage microcode file, easily write tools for administerators and so on. with the changes, we should put all intel-ucode/xx-xx-xx microcode files into the firmware dir (I had a tool to split previous big data file into small one and later we will release new style data file). The init script should be changed to just loading the driver without unloading Signed-off-by: Shaohua Li <shaohua.li@intel.com> Acked-by: Tigran Aivazian <tigran@veritas.com> Cc: Greg KH <greg@kroah.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2006-09-27[PATCH] inode-diet: Eliminate i_blksize from the inode structureTheodore Ts'o
This eliminates the i_blksize field from struct inode. Filesystems that want to provide a per-inode st_blksize can do so by providing their own getattr routine instead of using the generic_fillattr() function. Note that some filesystems were providing pretty much random (and incorrect) values for i_blksize.

2006-09-27[PATCH] inode_diet: Replace inode.u.generic_ip with inode.i_privateTheodore Ts'o
The following patches reduce the size of the VFS inode structure by 28 bytes on a UP x86. (It would be more on an x86_64 system). This is a 10% reduction in the inode size on a UP kernel that is configured in a production mode (i.e., with no spinlock or other debugging functions enabled; if you want to save memory taken up by in-core inodes, the first thing you should do is disable the debugging options; they are responsible for a huge amount of bloat in the VFS inode structure). This patch: The filesystem or device-specific pointer in the inode is inside a union, which is pretty pointless given that all 30+ users of this field have been using the void pointer. Get rid of the union and rename it to i_private, with a comment to explain who is allowed to use the void pointer. This is just a cleanup, but it allows us to reuse the union 'u' for something something where the union will actually be used.

2006-09-26PCI: Multiprobe sanitizerAlan Cox
There are numerous drivers that can use multithreaded probing but having some kind of global flag as the way to control this makes migration to threaded probing hard and since it enables it everywhere and is almost as likely to cause serious pain as holding a clog dance in a minefield. If we have a pci_driver multithread_probe flag to inherit you can turn it on for one driver at a time. From playing so far however I think we need a different model at the device layer which serializes until the called probe function says "ok you can start another one now". That would need some kind of flag and semaphore plus a helper function. Anyway in the absence of that this is a starting point to usefully play with this stuff Signed-off-by: Alan Cox <alan@redhat.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

2006-09-26PCI-Express AER implemetation: AER core and aerdriverZhang, Yanmin
Patch 3 implements the core part of PCI-Express AER and aerdrv port service driver. When a root port service device is probed, the aerdrv will call request_irq to register irq handler for AER error interrupt. When a device sends an PCI-Express error message to the root port, the root port will trigger an interrupt, by either MSI or IO-APIC, then kernel would run the irq handler. The handler collects root error status register and schedules a work. The work will call the core part to process the error based on its type (Correctable/non-fatal/fatal). As for Correctable errors, the patch chooses to just clear the correctable error status register of the device. As for the non-fatal error, the patch follows generic PCI error handler rules to call the error callback functions of the endpoint's driver. If the device is a bridge, the patch chooses to broadcast the error to downstream devices. As for the fatal error, the patch resets the pci-express link and follows generic PCI error handler rules to call the error callback functions of the endpoint's driver.
