mptfusion: enable no_write_same for vmware scsi disks
When using a virtual SCSI disk in a VMWare VM if blkdev_issue_zeroout is used
data can be improperly zeroed out using the mptfusion driver. This patch
disables write_same for this driver and the vmware subsystem_vendor which

Resending the patch. Addressed the review comments from Tomas Henzl.
Added comment for to-do work.
Problem statement:
MFI link list in megaraid_sas driver is used from mfi-mpt pass-through commands.
This list can be corrupted due to many possible race conditions in driver and
eventually we may see kernel panic.
One example -
MFI frame is freed from calling process as driver send command via polling method and interrupt
for that command comes after driver free mfi frame (actually even after some other context reuse
the mfi frame). When driver receive MPT frame in ISR, driver will be using the index of MFI and
access that MFI frame and finally in-used MFI frame’s list will be corrupted.
High level description of new solution -
Free MFI and MPT command from same context.
Free both the command either from process (from where mfi-mpt pass-through was called) or from
ISR context. Do not split freeing of MFI and MPT, because it creates the race condition which
will do MFI/MPT list corruption.
Renamed the cmd_pool_lock which is used in instance as well as fusion with below name.
mfi_pool_lock and mpt_pool_lock to add more code readability.

megaraid_sas : Round down max sge supported by controller to power of two
Resending the patch. Addressed the review comments from Tomas Henzl.
Round down the max sge to power of two.
Earlier max sge limit is 70 SGE, which will allow block layer to send 280K IO frame.
It is optimal to provide max IO size aligned to the smallest possible stripe size.
E.a
Consider that we have configured RAID Volumes which does not allow Fast Path across the stripe.
Raid volume with stripe size = 256K, will have peformance hit if we get io frame of size 280K.
Driver will not send IO frame large than stripe size to the Fast Path.
Also, FW will convert 280K frame into 256K + 24K. This is an additional overhead.

Resending the patch. Addressed the review comments from Tomas Henzl.
reserved1 field(part of union) of Raid map struct was not required so it is removed.
Current MegaRAID firmware and hence the driver only supported 64VDs.
E.g: If the user wants to create more than 64VD on a controller,
it is not possible on current firmware/driver.
New feature and requirement to support upto 256VD, firmware/driver/apps need changes.
In addition to that there must be a backward compatibility of the new driver with the
older firmware and vice versa.
RAID map is the interface between Driver and FW to fetch all required
fields(attributes) for each Virtual Drives.
In the earlier design driver was using the FW copy of RAID map where as
in the new design the Driver will keep the RAID map copy of its own; on which
it will operate for any raid map access in fast path.
Local driver raid map copy will provide ease of access through out the code
and provide generic interface for future FW raid map changes.
For the backward compatibility driver will notify FW that it supports 256VD
to the FW in driver capability field.
Based on the controller properly returned by the FW, the Driver will know
whether it supports 256VD or not and will copy the RAID map accordingly.
At any given time, driver will always have old or new Raid map.
So with this changes, driver can also work in host lock less mode. Please
see next patch which enable host lock less mode for megaraid_sas driver.

megaraid_sas : Firmware crash dump feature support
Resending the patch. Addressed the review comments from Tomas Henzl.
Move buff_offset inside spinlock, corrected loop at crash dump buffer free,
reset_devices check is added to disable fw crash dump feature in kdump kernel.
This feature will provide similar interface as kernel crash dump feature.
When megaraid firmware encounter any crash, driver will collect the firmware raw image and
dump it into pre-configured location.
Driver will allocate two different segment of memory.
#1 Non-DMA able large buffer (will be allocated on demand) to capture actual FW crash dump.
#2 DMA buffer (persistence allocation) just to do a arbitrator job.
Firmware will keep writing Crash dump data in chucks of DMA buffer size into #2,
which will be copy back by driver to the host memory as described in #1.
Driver-Firmware interface:
==================
A.) Host driver can allocate maximum 512MB Host memory to store crash dump data.
This memory will be internal to the host and will not be exposed to the Firmware.
Driver may not be able to allocate 512 MB. In that case, driver will do possible memory
(available at run time) allocation to store crash dump data.
Let’s call this buffer as Host Crash Buffer.
Host Crash buffer will not be contigious as a whole, but it will have multiple chunk of contigious memory.
This will be internal to driver and firmware/application are unaware of it.
Partial allocation of Host Crash buffer may have valid information to debug depending upon
what was collected in that buffer and depending on nature of failure.
Complete Crash dump is the best case, but we do want to capture partial buffer just to grab something rather than nothing.
Host Crash buffer will be allocated only when FW Crash dump data is available,
and will be deallocated once application copy Host Crash buffer to the file.
Host Crash buffer size can be anything between 1MB to 512MB. (It will be multiple of 1MBs)
B.) Irrespective of underlying Firmware capability of crash dump support,
driver will allocate DMA buffer at start of the day for each MR controllers.
Let’s call this buffer as “DMA Crash Buffer”.
For this feature, size of DMA crash buffer will be 1MB.
(We will not gain much even if DMA buffer size is increased.)
C.) Driver will now read Controller Info sending existing dcmd “MR_DCMD_CTRL_GET_INFO”.
Driver should extract the information from ctrl info provided by firmware and
figure out if firmware support crash dump feature or not.
Driver will enable crash dump feature only if
“Firmware support Crash dump” +
“Driver was able to create DMA Crash Buffer”.
If either one from above is not set, Crash dump feature should be disable in driver.
Firmware will enable crash dump feature only if “Driver Send DCMD- MR_DCMD_SET_CRASH_BUF_PARA with MR_CRASH_BUF_TURN_ON”
Helper application/script should use sysfs parameter fw_crash_xxx to actually copy data from
host memory to the filesystem.

megaraid_sas : Update threshold based reply post host index register
Resending the patch. Addressed the review comments from Tomas Henzl.
Current driver updates reply post host index to let firmware know that replies are processed,
while returning from ISR function, only if there is no oustanding replies in reply queue.
Driver will free the request frame immediately from ISR but reply post host index is not yet updated.
It means freed request can be used by submission path and there may be a tight loop in request/reply
path. In such condition, firmware may crash when it tries to post reply and there is no free
reply post descriptor.
Eventually two things needs to be change to avoid this issue.
Increase reply queue depth (double than request queue) to accommodate worst case scenario.
Update reply post host index to firmware once it reach to some pre-defined threshold value.
This change will make sure that firmware will always have some buffer of reply descriptor and
will never find empty reply descriptor in completion path.

mpt3sas: Added Reply Descriptor Post Queue (RDPQ) Array support
Up to now, Driver allocates a single contiguous block of memory
pool for all reply queues and passes down a single address in the
ReplyDescriptorPostQueueAddress field of the IOC Init Request
Message to the firmware.
When firmware receives this address, it will program each of the
Reply Descriptor Post Queue registers, as each reply queue has its
own register. Thus the firmware, starting from a base address it
determines the starting address of the subsequent reply queues
through some simple arithmetic calculations.
The size of this contiguous block of memory pool is directly proportional
to number of MSI-X vectors and the HBA queue depth. For example higher
MSIX vectors requires larger contiguous block of memory pool.
But some of the OS kernels are unable to allocate this larger
contiguous block of memory pool.
So, the proposal is to allocate memory independently for each
Reply Queue and pass down all of the addresses to the firmware.
Then the firmware will just take each address and program the value
into the correct register.
When HBAs with older firmware(i.e. without RDPQ capability) is used
with this new driver then the max_msix_vectors value would be set
to 8 by default.
Change set in v1:
1. Declared the _base_get_ioc_facts() functions at the beginning of the mpt3sas_base.c file

2. Initially set the consistent DMA mask to 32 bit and then change it to 64 bit mask
after allocating RDPQ pools by calling the function _base_change_consistent_dma_mask.
This is to ensure that all the upper 32 bits of RDPQ entries's base address to be same.
3. Reduced the redundancy between the RDPQ and non-RDPQ support in these following functions
a. _base_release_memory_pools()
b. _base_allocate_memory_pools()
c. _base_send_ioc_init()

qla2xxx: Prevent removal and board_disable race
Introduce mutual exclusion between the qla2xxx_remove_one PCI driver
callback and qla2x00_disable_board_on_pci_error, which is scheduled as
board_disable work by qla2x00_check_reg{32,16}_for_disconnect:
* Leave the driver-specific data attached to the underlying PCI device
intact in qla2x00_disable_board_on_pci_error, so that qla2x00_remove_one
has enough breadcrumbs to determine that any board_disable work has been
completed.
* In qla2xxx_remove_one, set a bit to prevent any subsequent
board_disable work from scheduling, then cancel and wait until pending
work has completed.
* Reuse the PCI device enable count check in qla2x00_remove_one to
determine if board_disable has occured. The original purpose of this
check was unnecessary since the driver remove function wasn't called
when the probe fails.
