This patch fix for sata IO circular lock dependency. When we call task_done
for SATA IO, we have got pm8001_ha->lock ,and in sas_ata_task_done, it will
get (dev->sata_dev.ap->lock. then cause circular lock dependency .So we
should drop pm8001_ha->lock when we call task_done for SATA task.

Due to typo error driver was failing TMF Abort Task request when
ctask->sc != NULL. Fixed code to fail TMF ABORT Task request only when
ctask->sc == NULL. Clear age component (19 most significant bits) of
reference ITT carried in iSCSI TMF PDU. Age component is internal to
initiator side and only lower bits of ITT as defined by ISCSI_ITT_MASK
is is sent on wire. Retrieve LUN directly from the ref_sc and update
SQ wqe as per chip HSI (Host Software Interface) specification

This issue was discovered during 10G iscsi testing
Default value of 'sq_size' module parameter is '0' which means driver
should use predefined SQ queue size when setting up iscsi connection.
roundup_pow_of_two(0) results in '1' and forces driver to setup
connections with send queue size of '1' and results in lower
performance as well

After commits c82f63e411f1b58427c103bd95af2863b1c96dd1 (PCI: check saved
state before restore) and 4b77b0a2ba27d64f58f16d8d4d48d8319dda36ff (PCI:
Clear saved_state after the state has been restored) PCI drivers are
prevented from restoring the device standard configuration registers
twice in a row. These changes introduced a regression on ipr EEH
recovery.
The ipr device driver saves the PCI state only during the device probe
and restores it on ipr_reset_restore_cfg_space() during IOA resets. This
behavior is causing the EEH recovery to fail after the second error
detected, since the registers are not being restored.
One possible solution would be saving the registers after restoring
them. The problem with this approach is that while recovering from an
EEH error if pci_save_state() results in an EEH error, the adapter/slot
will be reset, and end up back in ipr_reset_restore_cfg_space(), but it
won't have a valid saved state to restore, so pci_restore_state() will
fail.
The following patch introduces a workaround for this problem, hacking
around the PCI API by setting pdev->state_saved = true before we do the
restore. It fixes the EEH regression and prevents that we hit another
EEH error during EEH recovery.

Powerpc 44x uses 36 bit real address while the real address defined in
MPT Fusion driver is of type 32 bit. This causes ioremap to fail and
driver fails to initialize. This fix changes the data types
representing the real address from unsigned long 32-bit types to
resource_size_t which is 64-bit. The driver has been tested, the disks
get discovered correctly and can do IO.

So, it appears that qla2xxx dpc thread is moving forward before the
scsi host has been completely added.
This patch moves the setting of the init_done (and online) flag to
after the call to scsi_add_host() to hold off the dpc thread.
Found via large lun count testing using 2.6.31.

So libosd has decided to sacrifice some code simplicity for the sake of
a clean API. One of these things is the possibility for users to call
osd_end_request, in any condition at any state. This opens up some
problems with calling blk_put_request when out-side of the completion
callback but calling __blk_put_request when detecting a from-completion
state.
The current hack was working just fine until exofs decided to operate on
all devices in parallel and wait for the sum of the requests, before
deallocating all osd-requests at once. There are two new possible cases
1. All request in a group are deallocated as part of the last request's
async-done, request_queue is locked.
2. All request in a group where executed asynchronously, but
de-allocation was delayed to after the async-done, in the context of
another thread. Async execution but request_queue is not locked.
The solution I chose was to separate the deallocation of the osd_request
which has the information users need, from the deallocation of the
internal(2) requests which impose the locking problem. The internal
block-requests are freed unconditionally inside the async-done-callback,
when we know the queue is always locked. If at osd_end_request time we
still have a bock-request, then we know it did not come from within an
async-done-callback and we can call the regular blk_put_request.
The internal requests were used for carrying error information after
execution. This information is now copied to osd_request members for
later analysis by user code.
The external API and behaviour was unchanged, except now it really
supports what was previously advertised.

On the large servers, I/O port resource may not be assigned to all
the PCI devices since it is limited (to 64KB on Intel Architecture[1])
and it may also be fragmented (I/O base register of PCI-to-PCI bridge
will usually be aligned to a 4KB boundary[2]).
If no I/O port resource is assigned to devices, those devices do not
work.
[1] Some machines support 64KB I/O port space per PCI segment.
[2] Some P2P bridges support optional 1KB aligned I/O base.
Therefore, I made a patch for MegaRAID SAS driver to make PCI legacy
I/O port free. I have also tested the patch and it had no problem.
The way to make PCI legacy I/O port free is the same as Fusion-MPT
driver's and it has been merged into 2.6.30.4.
This has already been fixed in e1000 and lpfc.
As a result of the above, the driver can handle its device even when
there are a huge number of PCI devices being used on the system and no
I/O port region assigned to the device.

Based on patch originally by Jeff Mahoney <jeffm@suse.com>
enclosure_status is expected to be a NULL terminated array of strings
but isn't actually NULL terminated. When writing an invalid value to
/sys/class/enclosure/.../.../status, it goes off the end of the array
and Oopses.
Fix by making the assumption true and adding NULL at the end.

dio transfer always resets mdata->page_order to zero. It breaks
high-order pages previously allocated for non-dio transfer.
This patches adds reserved_page_order to st_buffer structure to save
page order for non-dio transfer.
http://bugzilla.kernel.org/show_bug.cgi?id=14563
When enlarge_buffer() allocates 524288 from 0, st uses six-order page
allocation. So mdata->page_order is 6 and frp_seg is 2.
After that, if st uses dio, sgl_map_user_pages() sets
mdata->page_order to 0 for st_do_scsi(). After that, when we call
normalize_buffer(), it frees only free frp_seg * PAGE_SIZE (2 * 4096)
though we should free frp_seg * PAGE_SIZE << 6 (2 * 4096 << 6). So we
see buffer_size is set to 516096 (524288 - 8192).

PMC-Sierra mgmt application uses SMI-S model. According to SMI-S, the
object model exposed by the SMI-S provider should show an StoragePool
which contains member disks of a RAID Virtual disk and StorageVolume
based on the StoragePool. But according to SMI-S, there is a possibility
where StoragePool is created but StorageVolume is not yet created. To
satisfy this scenario, we are trying a hidden RAID Virtual disk. The
hidden RAID virtual disk will not be exposed to OS. Once a StorageVolume
is created for this RAID virtual disk it is exposed.

The Octeon MGMT Ethernet ports are present in some members of the
Octeon SOC family (cn52XX and cn56XX have them).
The mdio bus connected to the MGMT PHYs is shared with the main
octeon-ethernet driver, we force it to be loaded first by calling
octeon_mdiobus_force_mod_depencency. The platform devices for the
MGMT Ethernet ports are added in
arch/mips/cavium-octeon/octeon-platform.c, and the register
definitions for the ports live in arch/mips/include/asm/octeon/ along
with their ilk.
Although it currently is the only driver in drivers/net/octeon, the
directory was created looking forward to the day that octeon-ethernet
will move there from its current home in drivers/staging.

The Octeon SOC has two types of Ethernet ports, each type with its own
driver. However, the PHYs for all the ports are controlled by a
common MDIO bus. Because the mdio driver is not associated with a
particular driver, but is instead a system level resource, we create s
stand-alone driver for it.
As for the driver, we put the register definitions in
arch/mips/include/asm/octeon where most of the other Octeon register
definitions live. This is a platform driver with the platform device
for "mdio-octeon" being registered in the platform startup code.

Each SPI controller has exactly one CS line and as such doesn't
provide for multi-cs. We implement a workaround to support
multi-cs by _not_ configuring the mux'ed CS pin for each SPI
controller. The CS mechanism is assumed to be fully machine
specific - the driver doesn't even assume some GPIO pin is used
to control the CS.
The driver selects between DMA and POLLING mode depending upon
the xfer size - DMA mode for xfers bigger than FIFO size, POLLING
mode otherwise.
The driver has been designed to be capable of running SoCs since
s3c64xx and till date, for that reason some of the register fields
have been passed via, SoC specific, platform data.

If len > BUFFER_LEN and !xfer->rx_buf we end up calculating the tx buffer
address as
*tx_dma = xfer->tx_dma + xfer->len - BUFFER_SIZE;
which is constant; i.e. we just send the last BUFFER_SIZE data over again
until we've reached the right number of bytes.
This patch gets around this by using the /requested/ length when
calculating addresses.
Note there's no way len != *plen when we calculate the rx buffer address
but conceptually we should be using *plen and I don't want someone to come
through later, see the calculations for rx and tx are different and "clean
up" back to what we had.

Add pseudo-DMA by FIQ to the S3C24XX SPI driver. This allows the driver
to get DMA-like performance where there are either no free DMA channels or
when doing transfers that required both TX and RX data paths.
Since this patch requires the addition of an assembly file to hold the FIQ
code, we rename the module (instead of adding a rename of the .c file to
this patch). We expect most users are loading this via udev and thus
there should be no change to the userland configuration.
