Currently the physical randomization's lower boundary is the original

Controllers use data strobe line to latch data from devices

Currently sdhci-arasan 5.1 can support enhanced strobe function,

The old implementation was overcomplicated and slightly bugged in some
corner cases.
Consider following state of BSS-es (limited to 6 for simplification):
drvr->iflist[0]: { bsscfgidx:0, ndev->name:wlan1, }
drvr->iflist[1]: (null)
drvr->iflist[2]: { bsscfgidx:2, ndev->name:wlan1-1, }

We don't need to split freepages with holding the zone lock. It will cause
more contention on zone lock so not desirable.

Page owner will be changed to store more deep stacktrace

Currently, we store each page's allocation stacktrace on corresponding
page_ext structure and it requires a lot of memory. This causes the problem
that memory tight system doesn't work well if page_owner is enabled.
Moreover, even with this large memory consumption, we cannot ge

This patch is motivated from Hugh and Vlastimil's concern [1].
There are two ways to get freepage from the allocator. One is using

split_page() calls set_page_owner() to set up page_owner to each pages.
But, it has a drawback that head page and the others have different

numa_init(of_numa_init) may returned error because of numa configuration
error. So "No NUMA configuration found" is inaccurate. In fact, specific
configuration error information can be immediately printed by the
testing branch. So "No NUMA..." only needs to be printed when numa_off.

Because we don't known how many memory blocks maybe contained, so we try

In the series [0] I included a patch which attempted to avoid redundant driver
calls in the schedutil governor by mapping the raw required CPU frequencies to
driver frequencies. This vastly increases the likelihood of detecting a
redundant cpufreq driver call, i.e. one which will end up attempting

frequency to a driver-supported frequency without actually setting it.

The slow-path frequency transition path is relatively expensive as it
requires waking up a thread to do work. Should support be added for
