This patch changes the read I/O to the HPB read I/O.
If the logical address of the read I/O belongs to active sub-region, the
HPB driver modifies the read I/O command to HPB read. It modifies the upiu
command of UFS instead of modifying the existing SCSI command.
In the HPB version 1.0, the maxim
This is a patch for managing L2P map in HPB module.
The HPB divides logical addresses into several regions. A region consists
of several sub-regions. The sub-region is a basic unit where L2P mapping is
managed. The driver loads L2P mapping data of each sub-region. The loaded
sub-region is called a
This is a patch for the HPB module.
The HPB module queries UFS for device information during initialization.

The helpers for parsing the options are often situated just above the
first function using them. As result, these helpers can be found a bit
everywhere in the code, it's messy and doesn't help to reuse these helpers.

Reorganize a little the logic to handle adding the absolute time stamp,
extended and forced time stamps, in such a way to remove a branch or two.
This is just a micro optimization.

Up until now, if an event is interrupted while it is recorded by an
interrupt, and that interrupt records events, the time of those events will
all be the same. This is because events only record the delta of the time

Make a helper function rb_add_timestamp() that moves the adding of the
extended time stamps into its own function. Also, remove the noinline and

make a difference (just let gcc decide).

Linus,
Please pull DT fixes for 5.8. I wouldn't normally update dtc at this
point in the cycle, but I've been waiting on fixes to land upstream for
a while now.

This change adds a new kernel configuration that sets the l1d cache
flush setting at compile time rather than at run time.
