Hannes Reinecke 69cd39e946 [SCSI] megaraid_mbox: fix Dell CERC firmware problem
Newer Dell CERC firmware (>= 6.62) implement a random deletion handling
compatible with the legacy megaraid driver.  The legacy handling shifted
the target ID by 0x80 only for I/O commands (READ/WRITE/etc), whereas
megaraid_mbox shifts the target ID always if random deletion is supported.
The resulted in megaraid_mbox sending an INQUIRY to the wrong channel, and
not finding any devices, obviously.

So we disable the random deletion support if the offending firmware is
found.

Matthias Kaehlcke 0c2cc43379 [SCSI] megaraid_mbox: use mutex instead of semaphore
The Megaraid Mailbox driver uses a semaphore as mutex.  Use the mutex API
instead of the (binary) semaphore.

Sumant Patro cd96d96f20 [SCSI] megaraid_{mm,mbox}: init fix for kdump
1.      Changes in Initialization to fix kdump failure.
        Send SYNC command on loading.
        This command clears the pending commands in the adapter
        and re-initialize its internal RAID structure.
        Without this change, megaraid driver either panics or fails to
        initialize the adapter during kdump's second kernel boot
        if there are pending commands or interrupts from other devices
        sharing the same IRQ.
2.      Authors email-id domain name changed from lsil.com to lsi.com.
        Also modified the MODULE_AUTHOR to megaraidlinux@lsi.com

Ju, Seokmann fbf6080225 [SCSI] megaraid_{mm,mbox}: 64-bit DMA capability checker
This patch contains
- a fix for 64-bit DMA capability check in megaraid_{mm,mbox} driver.
- includes changes (going back to 32-bit DMA mask if 64-bit DMA mask
failes) suggested by James with previous patch.
- addition of SATA 150-4/6 as commented by Vasily Averin.

With patch, the driver access PCIconfiguration space with dedicated
offset to read a signature. If the signature read, it means that the
controller has capability to handle 64-bit DMA.
Without this patch, the driver used to blindly claim 64-bit DMA
capability.
The issue has been reported by Vasily Averin [vvs@sw.ru].
Thank you Vasily for the reporting.

Ju, Seokmann c005fb4fb2 [SCSI] megaraid_{mm,mbox}: fix a bug in reset handler
When abort failed, the driver gets reset handleer called.  In the reset
handler, driver calls 'scsi_done()' callback for same SCSI command packet
(struct scsi_cmnd) multiple times if there are multiple SCSI command packet
in the pend_list.  More over, if there are entry in the pend_lsit with
IOCTL packet associated, the driver returns it to wrong free_list so that,
in turn, the driver could end up with 'NULL pointer dereference..' during
I/O command building with incorrect resource.

Also, the patch contains several minor/cosmetic changes besides this.

Linus Torvalds 1da177e4c3 Linux-2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
