The device limit of 128 tape drives was established in 2003 as a
significant increase from the 8 tape drives allowed previously.
We're seeing customer sites that between a large number of drives
and multipath are discovering more than 128 devices and running
into problems.
Now that we're not stuck having to store a pointer in array
and aren't limited by kmalloc failing on higher order allocs we can
lift the limit to fill the entire minor range based on the number
of modes.
Based on the current code, that's 2^17 devices.

Pull the MCA deletion branch from Paul Gortmaker:
"It was good that we could support MCA machines back in the day, but
realistically, nobody is using them anymore. They were mostly limited
to 386-sx 16MHz CPU and some 486 class machines and never more than
64MB of RAM. Even the enthusiast hobbyist community seems to have
dried up close to ten years ago, based on what you can find searching
various websites dedicated to the relatively short lived hardware.
So lets remove the support relating to CONFIG_MCA. There is no point
carrying this forward, wasting cycles doing routine maintenance on it;
wasting allyesconfig build time on validating it, wasting I/O on git
grep'ping over it, and so on."
Let's see if anybody screams. It generally has compiled, and James
Bottomley pointed out that there was a MCA extension from NCR that
allowed for up to 4GB of memory and PPro-class machines. So in *theory*
there may be users out there.
But even James (technically listed as a maintainer) doesn't actually
have a system, and while Alan Cox claims to have a machine in his cellar
that he offered to anybody who wants to take it off his hands, he didn't
argue for keeping MCA support either.
So we could bring it back. But somebody had better speak up and talk
about how they have actually been using said MCA hardware with modern
kernels for us to do that. And David already took the patch to delete
all the networking driver code (commit a5e371f61ad3: "drivers/net:
delete all code/drivers depending on CONFIG_MCA").
* 'delete-mca' of git://git.kernel.org/pub/scm/linux/kernel/git/paulg/linux:
MCA: delete all remaining traces of microchannel bus support.
scsi: delete the MCA specific drivers and driver code
serial: delete the MCA specific 8250 support.
arm: remove ability to select CONFIG_MCA
The support for CONFIG_MCA is being removed, since the 20
year old hardware simply isn't capable of meeting today's
software demands on CPU and memory resources.
This commit removes the MCA specific SCSI drivers, and the
MCA specific portions of code in dual role ISA/MCA drivers.
Also, the MCA specific SCSI documentation is removed.

The st tape driver recently added the MTWEOFI ioctl, which writes
a tape filemark (EOF), like the MTWEOF ioctl, except that MTWEOFI
returns immediately. This makes certain applications, like backup
software, run much more quickly on buffered tape drives.
Since legacy applications do not know about this new MTWEOFI ioctl,
this patch adds a new ioctl option that tells the st driver to return
immediately when writing an EOF (i.e. a filemark). This new flag
is much like the existing flag that tells the st driver to perform
writes (and certain other IOs) immediately, but this new flag only
applies to writing EOFs.
This new feature is controlled via the MTSETDRVBUFFER ioctl, using
the newly-defined MT_ST_NOWAIT_EOF flag.
Use of this new feature is displayed via the sysfs tape "options"
attribute.
The st documentation was updated to mention this new flag, as well
as the problems that can occur from using it.

This patch adds support for Universal Flash Storage(UFS)
host controllers. The UFS host controller driver
includes host controller initialization method.
The Initialization process involves following steps:
- Initiate UFS Host Controller initialization process by writing
to Host controller enable register
- Configure UFS Host controller registers with host memory space
datastructure offsets.
- Unipro link startup procedure
- Check for connected device
- Configure UFS host controller to process requests
- Enable required interrupts
- Configure interrupt aggregation

and actually reset the controller. For kdump to work properly it
is necessary that the reset_devices parameter be honored. This

designate a non-resettable controller as the dump device.
