035e9f4716 scsi: sbitmap: Silence a debug kernel warning triggered by sbitmap_put()
All sbitmap code uses implied preemption protection to update
sb->alloc_hint except sbitmap_put(). Using implied preemption protection is
safe since the value of sb->alloc_hint only affects performance of sbitmap
allocations but not their correctness. Change this_cpu_ptr() in
sbitmap_put() into raw_cpu_ptr() to suppress the following kernel warning
that appears with preemption debugging enabled (CONFIG_DEBUG_PREEMPT):

There are similar code implementations for WB configuration in
ufshcd_wb_{ctrl, toggle_flush_during_h8, toggle_flush}. Extract the common
parts to create a new helper with a flag parameter to reduce code
duplication.

Meanwhile, rename ufshcd_wb_ctrl() to ufshcd_wb_toggle() for better
readability. And remove unnecessary log messages from ufshcd_wb_config()
since relevant toggle function will emit messages. Also change
ufshcd_wb_toggle_flush{__during_h8} to void type accordingly.

Update the driver to use a function for referencing the UFS version.  This
replaces the UFSHCI_VERSION_xy macros, and supports comparisons where they
did not.

3d9c3dcc58 scsi: storvsc: Enable scatterlist entry lengths > 4Kbytes
storvsc currently sets .dma_boundary to limit scatterlist entries to 4
Kbytes, which is less efficient with huge pages that offer large chunks of
contiguous physical memory. Improve the algorithm for creating the Hyper-V
guest physical address PFN array so that scatterlist entries with lengths >
4Kbytes are handled.  As a result, remove the .dma_boundary setting.

The improved algorithm also adds support for scatterlist entries with
offsets >= 4Kbytes, which is supported by many other SCSI low-level
drivers.  And it retains support for architectures where possibly PAGE_SIZE
!= HV_HYP_PAGE_SIZE (such as ARM64).

471ee95ccc scsi: target: tcmu: Adjust parameter in call to tcmu_blocks_release()
In commit f7c89771d07d ("scsi: target: tcmu: Replace radix_tree with
XArray") the meaning of last parameter of tcmu_blocks_release() was
changed.  So in the callers we should subtract 1 from the previous
parameter.

Unfortunately that change got lost at one of the two places where
tcmu_blocks_release() is called. That does not lead to any problems, but we
should adjust it anyway.
