In case of a Secure-Storage-Access exception the effective aka virtual
address which caused the exception is contained within the TEID.
do_secure_storage_access() incorrectly uses phys_to_folio() instead of
virt_to_folio() to translate the virtual address to the corresponding
folio.
Fix this by using virt_to_folio() instead of phys_to_folio().

Remove the SCLP_OFB Kconfig option and enable the guarded code
unconditionally. This guards only a few lines of code, so the impact is
very low while at the same time this reduces the large number of Kconfig

debug_input_flush_fn() always copies one byte from the userspace buffer
with copy_from_user() regardless of the supplied write length. A
zero-length write therefore reads one byte beyond the caller's buffer.
If the stale byte happens to be '-' or a digit the debug log is
silently flushed. With an unmapped buffer the call returns -EFAULT.
Reject zero-length writes before copying from userspace.

debug_get_user_string() duplicates the userspace buffer with
memdup_user_nul() and then unconditionally looks at buffer[user_len - 1]
to strip a trailing newline.
A zero-length write reaches this helper unchanged, so the newline trim
reads before the start of the allocated buffer.
Reject empty writes before accessing the last input byte.

virt: coco: change tsm_class to a const struct
On Raspberry Pi 3B, the VEC clock is used by the VideoCore firmware
display driver, which remains active until the vc4 driver loads and
sends NOTIFY_DISPLAY_DONE. If this clock is disabled during boot, a bus
lockup happens and the firmware becomes unresponsive, causing a complete
system lockup.
Mark the VEC clock with CLK_IGNORE_UNUSED so it survives the unused
clock disablement and remains available until the vc4 driver takes over
display management.

The fixdep hostprog may be built multiple times during a single build.
Once during the configuration phase and later during the regular phase.
As only the regular build phase respects CONFIG_WERROR / W=e, the
compiler flags might change between the phases, leading to rebuilds.
Example, the rebuilds will happen twice on each invocation of the build:
$ make allyesconfig prepare
make[1]: Entering directory '/tmp/deleteme'
HOSTCC scripts/basic/fixdep
#
# No change to .config
#
HOSTCC scripts/basic/fixdep
DESCEND objtool
INSTALL libsubcmd_headers
make[1]: Leaving directory '/tmp/deleteme'
Fix the compilation flags used for scripts/basic/ before
scripts/Makefile.warn is evaluated to stop CONFIG_WERROR / W=e
influencing the fixdep build to avoid the spurious rebuilds.

The driver currently supports generating BCLK. There are systems which
require generation of MCLK instead. Register new MCLK clock and handle
clock-cells = <1> to differentiate between BCLK and MCLK. In case of a
legacy system with clock-cells = <0>, the driver behaves as before, i.e.
always returns BCLK.
Note that it is not possible re-use the current SAI audio driver to
generate MCLK and correctly enable and disable the MCLK.
If SAI (audio driver) is used to control the MCLK enablement, then MCLK
clock is not always enabled, and it is not necessarily enabled when the
codec may need the clock to be enabled. There is also no way for the
codec node to specify phandle to clock provider in DT, because the SAI
(audio driver) is not clock provider.
If SAI (clock driver) is used to control the MCLK enablement, then MCLK
clock is enabled when the codec needs the clock enabled, because the
codec is the clock consumer and the SAI (clock driver) is the clock
provider, and the codec driver can request the clock to be enabled when
needed. There is also the usual phandle to clock provider in DT, because
the SAI (clock driver) is clock provider.

clk_core_populate_parent_map() currently prefers the parent names over
the parent data and hws, so this isn't a problem at the moment. If that
ordering ever changed in the future, then this could lead to some
unexpected crashes. Let's just go ahead and make sure that the struct

Commit e2c318225ac1 ("kbuild: deb-pkg: add
pkg.linux-upstream.nokernelheaders build profile") changed how
install-extmod-build gets called, making it always rebuild the host
programs below scripts/ if HOSTCC wasn't specified with its full triplet
on the make command line. That is, apparently, needed to fix up commit
f1d87664b82a ("kbuild: cross-compile linux-headers package when
possible") for cross-compiles. However, in the much more common case of
non-cross-compile builds this will lead to unnecessary rebuilding of
host tools including gcc plugins. This, in turn, will lead to a full
kernel rebuild on the next 'make bindeb-pkg' which is unfortunate.
Avoid that by only triggering the rebuild of host tools for actual
cross-compile builds.

Commit 795cda8338ea ("rtc: interface: Fix long-standing race when setting
alarm") exposed an issue where the rtc-abx80x driver does not clear the
alarm feature bit, but instead relies on the set_alarm operation to return
invalid.
For example, when a RTC_UIE_ON ioctl is handled, it should abort at the
feature validation. Instead, it proceeds to the rtc_timer_enqueue(),
which used to return an error from the set_alarm call. However,
following the race condition handling, which likely should not be
discarding predecing errors, a success condition is returned to the
ioctl() caller. This results in (for example):
hwclock: select() to /dev/rtc0 to wait for clock tick timed out
Notwithstanding the validity of the race condition handling, if an interrupt
wasn't specified, or could not be attached, the driver should clear the
alarm feature bit.

On current firmware versions, RPI_FIRMWARE_SET_CLOCK_STATE doesn't
actually power off the clock. To achieve meaningful power savings, the
clock rate must be set to the minimum before disabling. This might be
fixed in future firmware releases.
Rather than pushing rate management to clock consumers, handle it
directly in the clock framework's prepare/unprepare callbacks. In
unprepare, set the rate to the minimum before disabling the clock.
In prepare, for clocks marked with `maximize` (currently v3d),
restore the rate to the maximum after enabling.

Gates (Multiple Gate clks that share an enable bit), standard Muxes,
Dividers and Gates. All clocks are implemented using custom clk ops and

debug_input_flush_fn() always copies one byte from the userspace buffer
with copy_from_user() regardless of the supplied write length. A
zero-length write therefore reads one byte beyond the caller's buffer.
If the stale byte happens to be '-' or a digit the debug log is
silently flushed. With an unmapped buffer the call returns -EFAULT.
Reject zero-length writes before copying from userspace.

debug_get_user_string() duplicates the userspace buffer with
memdup_user_nul() and then unconditionally looks at buffer[user_len - 1]
to strip a trailing newline.
A zero-length write reaches this helper unchanged, so the newline trim
reads before the start of the allocated buffer.
Reject empty writes before accessing the last input byte.

virt: coco: change tsm_class to a const struct
On Raspberry Pi 3B, the VEC clock is used by the VideoCore firmware
display driver, which remains active until the vc4 driver loads and
sends NOTIFY_DISPLAY_DONE. If this clock is disabled during boot, a bus
lockup happens and the firmware becomes unresponsive, causing a complete
system lockup.
Mark the VEC clock with CLK_IGNORE_UNUSED so it survives the unused
clock disablement and remains available until the vc4 driver takes over
display management.

The fixdep hostprog may be built multiple times during a single build.
Once during the configuration phase and later during the regular phase.
As only the regular build phase respects CONFIG_WERROR / W=e, the
compiler flags might change between the phases, leading to rebuilds.
Example, the rebuilds will happen twice on each invocation of the build:
$ make allyesconfig prepare
make[1]: Entering directory '/tmp/deleteme'
HOSTCC scripts/basic/fixdep
#
# No change to .config
#
HOSTCC scripts/basic/fixdep
DESCEND objtool
INSTALL libsubcmd_headers
make[1]: Leaving directory '/tmp/deleteme'
Fix the compilation flags used for scripts/basic/ before
scripts/Makefile.warn is evaluated to stop CONFIG_WERROR / W=e
influencing the fixdep build to avoid the spurious rebuilds.

The driver currently supports generating BCLK. There are systems which
require generation of MCLK instead. Register new MCLK clock and handle
clock-cells = <1> to differentiate between BCLK and MCLK. In case of a
legacy system with clock-cells = <0>, the driver behaves as before, i.e.
always returns BCLK.
Note that it is not possible re-use the current SAI audio driver to
generate MCLK and correctly enable and disable the MCLK.
If SAI (audio driver) is used to control the MCLK enablement, then MCLK
clock is not always enabled, and it is not necessarily enabled when the
codec may need the clock to be enabled. There is also no way for the
codec node to specify phandle to clock provider in DT, because the SAI
(audio driver) is not clock provider.
If SAI (clock driver) is used to control the MCLK enablement, then MCLK
clock is enabled when the codec needs the clock enabled, because the
codec is the clock consumer and the SAI (clock driver) is the clock
provider, and the codec driver can request the clock to be enabled when
needed. There is also the usual phandle to clock provider in DT, because
the SAI (clock driver) is clock provider.

clk_core_populate_parent_map() currently prefers the parent names over
the parent data and hws, so this isn't a problem at the moment. If that
ordering ever changed in the future, then this could lead to some
unexpected crashes. Let's just go ahead and make sure that the struct

Commit e2c318225ac1 ("kbuild: deb-pkg: add
pkg.linux-upstream.nokernelheaders build profile") changed how
install-extmod-build gets called, making it always rebuild the host
programs below scripts/ if HOSTCC wasn't specified with its full triplet
on the make command line. That is, apparently, needed to fix up commit
f1d87664b82a ("kbuild: cross-compile linux-headers package when
possible") for cross-compiles. However, in the much more common case of
non-cross-compile builds this will lead to unnecessary rebuilding of
host tools including gcc plugins. This, in turn, will lead to a full
kernel rebuild on the next 'make bindeb-pkg' which is unfortunate.
Avoid that by only triggering the rebuild of host tools for actual
cross-compile builds.

Commit 795cda8338ea ("rtc: interface: Fix long-standing race when setting
alarm") exposed an issue where the rtc-abx80x driver does not clear the
alarm feature bit, but instead relies on the set_alarm operation to return
invalid.
For example, when a RTC_UIE_ON ioctl is handled, it should abort at the
feature validation. Instead, it proceeds to the rtc_timer_enqueue(),
which used to return an error from the set_alarm call. However,
following the race condition handling, which likely should not be
discarding predecing errors, a success condition is returned to the
ioctl() caller. This results in (for example):
hwclock: select() to /dev/rtc0 to wait for clock tick timed out
Notwithstanding the validity of the race condition handling, if an interrupt
wasn't specified, or could not be attached, the driver should clear the
alarm feature bit.

On current firmware versions, RPI_FIRMWARE_SET_CLOCK_STATE doesn't
actually power off the clock. To achieve meaningful power savings, the
clock rate must be set to the minimum before disabling. This might be
fixed in future firmware releases.
Rather than pushing rate management to clock consumers, handle it
directly in the clock framework's prepare/unprepare callbacks. In
unprepare, set the rate to the minimum before disabling the clock.
In prepare, for clocks marked with `maximize` (currently v3d),
restore the rate to the maximum after enabling.

EcoNet EN751221 clock/reset driver is significantly similar to the
EN7523 / EN7581, however the EN751221 does not have a neat batch of clock
divider registers so there are fewer known clocks, and the frequency of
each clock is derived differently. This clock driver will probably work
correctly on EN751627, EN7528, and EN7580.

Add driver for clock controller in Tenstorrent Atlantis SoC. This version
of the driver covers clocks from RCPU subsystem.
5 types of clocks generated by this controller: PLLs (PLLs
with bypass functionality and an additional Gate clk at output), Shared
Gates (Multiple Gate clks that share an enable bit), standard Muxes,
Dividers and Gates. All clocks are implemented using custom clk ops and
use the regmap interface associated with the syscon. All clocks are derived
from a 24 Mhz oscillator.
The reset controller is also setup as an auxiliary device of the clock
