Currently we lazily-initialize a module's ftrace PLT at runtime when we
install the first ftrace call. To do so we have to apply a number of
sanity checks, transiently mark the module text as RW, and perform an
IPI as part of handling Neoverse-N1 erratum #1542419.
We only expect the ftrace

Hi,
This series is a reworked version of Torsten's v8 FTRACE_WITH_REGS
series [1]. I've tried to rework the existing code in preparatory
patches so that the patchable-function-entry bits slot in with fewer
surprises. This version is based on v5.4-rc3, and can be found in my
arm64/ftrace-with-regs
When using patchable-function-entry, the compiler will record the
callsites into a section named "__patchable_function_entries" rather
than "__mcount_loc". Let's abstract this difference behind a new
FTRACE_CALLSITE_SECTION, so that architectures don't have to handle this
explicitly (e.g. with
Now that we no longer refer to mod->arch.ftrace_trampolines in the body
of ftrace_make_call(), we can use IS_ENABLED() rather than ifdeffery,
and make the code easier to follow. Likewise in ftrace_make_nop().
Let's do so.

When we load a module, we have to perform some special work for a couple
of named sections. To do this, we iterate over all of the module's
sections, and perform work for each section we recognize.

Architectures may need to perform special initialization of ftrace
callsites, and today they do so by special-casing ftrace_make_nop() when
the expected branch address is MCOUNT_ADDR. In some cases (e.g. for
patchable-function-entry), we don't have an mcount-like symbol and don't
want a synthetic
For FTRACE_WITH_REGS, we're going to want to generate a MOV (register)

It turns out that the wcn3990 can float the gpio lines during bootup, etc
which will result in the uart core thinking there is incoming data. This
results in the bluetooth stack getting garbage. By applying a bias to
match what wcn3990 would drive, the issue is corrected.

dpm_sysfs_remove() and device_pm_remove() are already called by
device_del() on device removal so there is no need to call
device_init_wakeup(dev, false) from the driver and it allows to remove the
.remove callback.

When setting the time in the future with the uie timer enabled,
rtc_timer_do_work will loop for a while because the expiration of the uie
timer was way before the current RTC time and a new timer will be enqueued
until the current rtc time is reached.
If the uie timer is enabled, disable it
Never enable update interrupts when the time set on the rtc is invalid.
In that case, also avoid enabling the emulation because it will fail for
the same reason.
