30afcb4bd2 return pfn from direct_access, for XIP
Alter the block device ->direct_access() API to work with the new
get_xip_mem() API (that requires both kaddr and pfn are returned).

Some architectures will not do the right thing in their virt_to_page() for use
by XIP (to translate from the kernel virtual address returned by
direct_access(), to a user mappable pfn in XIP's page fault handler.

However, we can't switch it to just return the pfn and not the kaddr, because
we have no good way to get a kva from a pfn, and XIP requires the kva for its
read(2) and write(2) handlers.  So we have to return both.

0e88460da6 mm: introduce node_zonelist() for accessing the zonelist for a GFP mask
Introduce a node_zonelist() helper function.  It is used to lookup the
appropriate zonelist given a node and a GFP mask.  The patch on its own is a
cleanup but it helps clarify parts of the two-zonelist-per-node patchset.  If
necessary, it can be merged with the next patch in this set without problems.

c116bc2ae5 rtc: add the support for alarm time relative to current time in sysfs
In current kernel if we want to set the alarm time, the absolute time the
seconds relative to 1970-01-01 00:00:00) should be written into
/sys/class/rtc/rtc0/wakealarm.  It is not convenient.

It is more reasonable to add the support for the alarm time relative to
current RTC time.(the unit is second)

For example:
If the RTC is required to generate alarm after 2 minutes, the following
will be OK.
	echo +120 > /sys/class/rtc/rtc0/wakealarm
or      echo +0x78 > /sys/class/rtc/rtc0/wakealarm

e2bfe3424b rtc: rtc-rs5c372: fix up NULL name in transfer error path
rs5c_get_regs() currently uses rs5c->rtc->name for its debug printk when
i2c_transfer() fails, though it is used several times before the rtc dev
has been registered. The earliest we can get at the symbolic name is via
the i2c client's struct device, which can be handled by moving the first
rs5c_get_regs() until after the client pointer is assigned.

c750090085 rtc: avoid legacy drivers with generic framework
Kconfig tweaks to help reduce RTC configuration bugs, by avoiding
legacy RTC drivers when the generic RTC framework is enabled:

 - If rtc-cmos is selected, disable the legacy rtc driver;

 - When using generic RTC on x86, enable rtc-cmos by default;

 - In the old "chardev RTC" section of Kconfig, add a comment
   warning people off these (seven) legacy RTC drivers when
   the generic framework is in use.

People can still use the legacy drivers if they want (or need) to.

This doesn't fix the broken dependencies for the legacy "CMOS" RTC driver.
Ideally it would be a full list of platforms where it works, not a partial
list of ones where it won't.  Or better yet, it would depend on a
"HAVE_CMOS_RTC" flag defined by various platforms ...  surely there's a
Kconfig style guideline lurking there.

These are the statistics on a virtual adapter (subchannel) level.

bda232531f [SCSI] scsi_transport_fc: fc_user_scan correction
Way back when, when the fc_user_scan routine was created, it kept some
of its original logic that walked the rport list and kicked off a scan.
Unfortunately, it didn't keep any of the locking around the rport list,
nor did it consider the synchronous nature of the scan invoked. The result,
there are some scan requests where the rport list changes, thus a subsequent
scan is called on a bogus rport structure and the system NMI's.

1377d8dd7e [SCSI] FlashPoint: fix off-by-one errors
This patch fixes off-by-one errors in error checks (the variables are
used as array indexes for arrays with MAX_SCSI_TAR resp. MAX_LUN
elements) spotted by the Coverity checker.

2b48aed182 [SCSI] aic7xxx: Update type check in aicasm grammar
The function type_check() in aicasm grammar code was
never used properly due to a bug.
This patch fixes it up and ensures it's only called if appropriate.

In addition the unused 16bit instruction are disabled, but left in
the code for reference.

542bd1377a [SCSI] fix SLUB WARN_ON
We're getting a WARN_ON from SLUB indicating that we're trying to free
caches with in-use objects.  The root cause is a new dependency in the
command/sense free on unchecked_isa_dma.  The WARN_ON is caused by
drivers which change this in their setup after the command/sense cache
is allocated.

The fix is to move the allocation of this cache into scsi_add_host()
so things like gdth have an opportunity to modify it between alloc and
add (but *not* after).

The true fix would be to move unchecked_isa_dma into the template and
out of the host, so it because a truly read only variable.

077e3bdb9e ide-tape: remove tape->merge_stage
Get rid of the pipeline merge stage but retain the chrdev req caching
functionality by using a merge buffer tape->merge_bh which is flushed in chunks
of several blocks at a time. Also, remove last references to pipelining, e.g.
typedef idetape_stage_s.
