2006-09-28IB/ipath: Change HT CRC message to indicate how to resolve problemBryan O'Sullivan
The system must be powercycled to clear a HT CRC error; reloading the driver is not enough. Signed-off-by: Bryan O'Sullivan <bryan.osullivan@qlogic.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>

2006-09-28IB/iser: DMA unmap unaligned for RDMA data before touching itErez Zilber
iSER uses the DMA mapping api to map the page holding the SCSI command data to the HCA DMA address space. When the command data is not aligned for RDMA, the data is copied to/from an allocated buffer which in turn is used for executing this command. The pages associated with the command must be unmapped before being touched. Signed-off-by: Erez Zilber <erezz@voltaire.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>
2006-09-28IB/iser: Have iSER data transaction object point to iSER connErez Zilber
iSER uses a data transaction object (struct iser_dto) as part of its IB data descriptors (struct iser_desc) management. It also uses a hierarchy of connection structures pointing to each other. A DTO may exist even after the iscsi_iser connection pointed by it is destroyed (eg one that is bound to a post receive buffer which was flushed by the IB HW). Hence DTOs need point to the lowest connection, which is struct iser_conn. Signed-off-by: Erez Zilber <erezz@voltaire.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>

Another NULL dereference spotted by the Coverity checker (cid #1395): In case we can't alloc the vq_req, we goto bail1, where we call vq_req_free(c2dev, vq_req); which then dereferences vq_req.

2006-09-27[PATCH] de_thread: Use tsk not currentEric W. Biederman
Ingo Oeser pointed out that because current expands to an inline function it is more space efficient and somewhat faster to simply keep a cached copy of current in another variable.

2006-09-27[PATCH] pid: Implement transfer_pid and use it to simplify de_threadEric W. Biederman
In de_thread we move pids from one process to another, a rather ugly case. The function transfer_pid makes it clear what we are doing, and makes the action atomic. This is useful we ever want to atomically traverse the process group and session lists, in a rcu safe manner. Even if the atomic properties this change should be a win as transfer_pid should be less code to execute than executing both attach_pid and detach_pid, and this should make de_thread slightly smaller as only a single function call needs to be emitted. The only downside is that the code might be slower to execute as the odds are against transfer_pid being in cache. Signed-off-by: Eric W.

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: don't check the sizeShaohua Li
IA32 manual says if micorcode update's size is 0, then the size is default size (2048 bytes). But this doesn't suggest all microcode update's size should be above 2048 bytes to me.

2006-09-27[PATCH] x86 microcode: add sysfs and hotplug supportShaohua Li
Add sysfs support. Currently each CPU has three microcode related attributes. One is 'version' which shows current ucode version of CPU. Tools can use the attribute do validation or show CPU ucode status. one is 'reload' which allows manually reloading ucode. Another is 'processor_flags', which exports processor flags, so we can write tools to check if CPU has latest ucode. Also add suspend/resume and CPU hotplug support.

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>
