Commit 3adeb2566b9b ("MIPS: Loongson: Improve LEFI firmware interface")
made the number of UARTs dynamic if LEFI_FIRMWARE_INTERFACE is configured.
Unfortunately, it did not initialize the number of UARTs if
LEFI_FIRMWARE_INTERFACE is not configured. As a result, the Fulong2e
system has no console.

linux/io.h is needed because the driver uses:
readl_relaxed
writel_relaxed
writeq_relaxed

When a platform driver doesn't provide a .remove callback the function
platform_drv_remove isn't called and so the call to dev_pm_domain_attach
called at probe time isn't paired by dev_pm_domain_detach at remove
time.

This actually slipped through my review. IMHO madc should be

By copying BPF related operation to uprobe processing path, this patch
allow users attach BPF programs to uprobes like what they are already
doing on kprobes.
After this patch, users are allowed to use PERF_EVENT_IOC_SET_BPF on a
uprobe perf event. Which make it possible to

This adds the basic infrastructure to keep track of cycle counts per
basic block for annotate. We allocate an array similar to the normal
accounting, and then account branch cycles there.
We handle two cases:
cycles per basic block with start and cycles per branch (these are

Call the earlier added cycle histogram infrastructure from the perf

It is cumbersome to manually calculate the total time spent in a given

Instead, we now do this directly inside perf trace.

Later patches need to cheaply check that the branch mode is in ANY. Add
a new function to check all event attrs and add a flag to the report
state, which is then initialized.

Now that we can process branch data in annotate it makes sense to

for this is already in shared code with report. But we need to add:

Currently the value of a PMU config term is silently truncated if it is
too big. This is an impediment to validating the value for other
criteria later on i.e. the user provides an invalid value that gets
truncated to a valid one.
