2022-03-01ata: ahci: Rename CONFIG_SATA_LPM_MOBILE_POLICY configuration itemMario Limonciello
`CONFIG_SATA_LPM_MOBILE_POLICY` reflects a configuration to apply only to mobile chipsets. As some desktop boards may want to use this policy by default as well, rename the configuration item to `SATA_LPM_POLICY`.

2022-03-01ata: ahci: Rename `AHCI_HFLAG_IS_MOBILE`Mario Limonciello
`AHCI_HFLAG_IS_MOBILE` designates that a chipset should be using the default link power management policy from a kernel configuration item. As desktop chipsets may also be interested in this default policy configuration, rename the flag to `AHCI_HFLAG_USE_LPM_POLICY` to more accurately reflect that a chipset doesn't have to be mobile to adopt it.

2022-03-01ata: ahci: Rename board_ahci_mobileMario Limonciello
This board definition was originally created for mobile devices to designate default link power managmeent policy to influence runtime power consumption. As this is interesting for more than just mobile designs, rename the board to `board_ahci_low_power` to make it clear it is about default policy.

2022-02-20ata: libata-sff: refactor ata_sff_altstatus()Sergey Shtylyov
The driver's calls to ata_sff_altstatus() are mostly surrounded by some clumsy checks. Refactor ata_sff_altstatus() to include the repetitive checks and return a 'bool' result indicating if the alternate status register exists or not. While at it, further update the 'kernel-doc' comment -- the alternate status register has never been a part of the taskfile, despite what Jeff and co. think! :-) In ata_sff_lost_interrupt(), wrap the ata_sff_altstatus() call in a WARN_ON_ONCE() check to issue a warning if the device control register does not exist.

They include: - revert the fifo use for the 8250 console mode. It caused too many regressions and problems, and had a bug in it as well. This is being reworked and should show up in a later -rc1 release, but it's not ready for 5.17 - rpmsg tty race fix - restore the cyclades.h uapi header file. Turns out a compiler test suite used it for some unknown reason. Bring it back just for the parts that are used by the builder test so they continue to build. No functionality is restored as no one actually has this hardware anymore, nor is it really tested. - stm32 driver fixes - n_gsm flow control fixes - pl011 driver fix - rs485 initialization fix All of these have been in linux-next this week with no reported problems" * tag 'tty-5.17-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty: kbuild: remove include/linux/cyclades.h from header file check serial: core: Initialize rs485 RTS polarity already on probe serial: pl011: Fix incorrect rs485 RTS polarity on set_mctrl serial: stm32: fix software flow control transfer serial: stm32: prevent TDR register overwrite when sending x_char tty: n_gsm: fix SW flow control encoding/handling serial: 8250: of: Fix mapped region size when using reg-offset property tty: rpmsg: Fix race condition releasing tty port tty: Partially revert the removal of the Cyclades public API tty: Add support for Brainboxes UC cards.

2022-01-28dm: properly fix redundant bio-based IO accountingblock-5.17-2022-01-28Mike Snitzer
Record the start_time for a bio but defer the starting block core's IO accounting until after IO is submitted using bio_start_io_acct_time(). This approach avoids the need to mess around with any of the individual IO stats in response to a bio_split() that follows bio submission.

2022-01-28dm: revert partial fix for redundant bio-based IO accountingMike Snitzer
Reverts a1e1cb72d9649 ("dm: fix redundant IO accounting for bios that need splitting") because it was too narrow in scope (only addressed redundant 'sectors[]' accounting and not ios, nsecs[], etc).
