Rather than u32_swap and u64_swap working on 4- and 8-byte objects
directly, let them handle any multiple of 4 or 8 bytes. This speeds
up most users of sort() by avoiding fallback to the byte copy loop.
Despite what commit ca96ab859ab4 ("lib/sort: Add 64 bit swap function")
claims, very few
Rather than a fixed-size array of pending sorted runs, use the ->prev

some ugly overflow handling, and reduces the code size.

CONFIG_RETPOLINE has severely degraded indirect function call
performance, so it's worth putting some effort into reducing
the number of times cmp() is called.
This patch avoids badly unbalanced merges on unlucky input sizes.
It slightly increases the code size, but saves an average of 0.2*n
This uses fewer comparisons than the previous code (61% as
many for large random inputs), but produces identical results;
it actually performs the exact same series of swap operations.
Standard heapsort, when sifting down, performs two comparisons
per level: One to find the greater child, and a
Similar to what's being done in the net code, this takes advantage of
the fact that most invocations use only a few common swap functions, and
replaces indirect calls to them with (highly predictable) conditional

swap function,
Because CONFIG_RETPOLINE has made indirect calls much more expensive,
I thought I'd try to reduce the number made by the library sort
functions.
The first three patches apply to lib/sort.c.

Both I2C and SPI needs to be taken out of reset before being used. Earlier,
we relied on the bootloader to do the job but a more cleaner approach would
be to handle the reset in kernel. Hence, add the reset properties to
the nodes to let the corresponding drivers take the peripherals out of
reset.
For the AMBA Primecell devices having the reset lines wired, it is
necessary to take them out of reset before reading the pid and cid values.
Earlier we were dependent on the bootloader to do this but a more cleaner
approach would be to do it in the kernel itself. Hence, this commit
deasserts the

Hello,
This small patchset adds the reset functionality to the I2C and SPI
peripherals on HI6220 SoC from HiSilicon. Those peripherals needs to be
taken out of reset before being used. But earlier we were depending on the
bootloader to do the job but as suggested by Daniel Thompson, a more
ping.

On chromebooks, power_manager daemon normally shuts down(S5) the device
when the battery charge falls below 4% threshold. ChromeOS EC then
normally spends an hour in S5 before hibernating. If the battery charge
falls below critical threshold in the mean time, EC does a battery cutoff
instead of

rxrpc_get_client_conn() adds a new call to the front of the waiting_calls
queue if the connection it's going to use already exists. This is bad as
it allows calls to get starved out.
Fix this by adding to the tail instead.
Also change the other enqueue point in the same function to put it on

Introduce a printdate function to eliminate the repetitive use of
