mips: select legacy gpiolib interfaces where used

2026-06-15T10:32:43+00:00

A few old machines have not been converted away from the old-style gpiolib interfaces. Make these select the new CONFIG_GPIOLIB_LEGACY symbol so the code still works where it is needed but can be left out otherwise. This is the list of all gpio_request() calls in mips: arch/mips/alchemy/devboards/db1000.c: gpio_request(19, "sd0_cd"); arch/mips/alchemy/devboards/db1000.c: gpio_request(20, "sd1_cd"); arch/mips/alchemy/devboards/db1200.c: gpio_request(215, "otg-vbus"); arch/mips/bcm47xx/workarounds.c: err = gpio_request_one(usb_power, GPIOF_OUT_INIT_HIGH, "usb_power"); arch/mips/bcm63xx/boards/board_bcm963xx.c: gpio_request_one(board.ephy_reset_gpio, arch/mips/txx9/rbtx4927/setup.c: gpio_request(15, "sio-dtr"); Most of these should be easy enough to change to modern gpio descriptors or remove if they are no longer in use.

MIPS: VDSO: Fold MIPS_CLOCK_VSYSCALL into MIPS_GENERIC_GETTIMEOFDAY

2026-06-09T15:02:10+00:00

This configuration option exists so "that we don't provide the symbol when there's no possibility of there being a usable clocksource". However it only covers __vdso_gettimeofday() and none of the other vDSO functions which should be affected by the same circumstances.slightly slightly. Remove MIPS_CLOCK_VSYSCALL and fold its usecase into MIPS_GENERIC_GETTIMEOFDAY, which works correctly.

MIPS: VDSO: Gate microMIPS restriction on GCC version

As explained in the comment, the problematic GOT references are only emitted by old versions of GCC. Limit the restriction to those compilers.

MIPS: VDSO: Fold MIPS_DISABLE_VDSO into MIPS_GENERIC_GETTIMEOFDAY

2026-06-09T15:02:10+00:00

The currently used MIPS_DISABLE_VDSO will disable only the userspace bits of the time-related vDSO. The kernel part is still pointlessly built and running. Remove MIPS_DISABLE_VDSO and fold its usecase into MIPS_GENERIC_GETTIMEOFDAY, which works correctly.

MIPS: VDSO: Only map the data pages when the vDSO is used

A future change will make it possible to disable the time-related vDSO. In that case there is no point in calling into the datastore.

arch: select HAVE_ARCH_BITREVERSE conditionally on BITREVERSE

2026-05-28T15:39:16+00:00

Architectures may have bit reversal instructions, but if the API not needed, the corresponding option should not be selected because it may lead to generating the unneeded code. Signed-off-by: Yury Norov
