Hi,
Here are 2 fixes we found while testing the cdns3 driver
on our platform.
The first one fixes a corner case where super-speed in host mode
doesn't work if device was plugged before the cdns3 driver probes.
The second one fixes the case when gadget driver is
limited to full-speed.

This patch restores the correct DMA mask after switching back to device
mode.
The issue occurred because Device part of controller use 32 bits DMA and
Host side use 64 bits DMA. During loading XHCI driver the DMA mask
used by driver is overwritten by XHCI driver so it must be restored
to 32 bits.
Dequeuing implementation in cdns3_gadget_ep_dequeu gets first request from
deferred_req_list and changed TRB associated with it to LINK TRB.
This approach is incorrect because deferred_req_list contains requests
that have not been placed on hardware RING. In this case driver should
just giveback

This series, which depends on the previous two, introduces static_call().
static_call(), is the idea of static_branch() applied to indirect function
calls. Remove a data load (indirection) by modifying the text.
These patches are still based on the work Josh did earlier, but incorporated
Future patches will need to poke a RET instruction, provide the
infrastructure required for this.

This allows the patching to to emit 2 byte JMP/NOP instruction in
addition to the 5 byte JMP/NOP we already did. This allows for more
compact code.
This code is not yet used, as we don't emit shorter code at compile
time yet.

The __ADDRESSABLE() macro uses the __LINE__ macro to create a temporary
symbol which has a unique name. However, if the macro is used multiple
times from within another macro, the line number will always be the
same, resulting in duplicate symbols.

In order to use static_call() to wire up x86_pmu, we need to
initialize earlier; copy some of the tricks from jump_label to enable
this.
Primarily we overload key->next to store a sites pointer when there
are no modules, this avoids having to use kmalloc() to initialize the
sites and allows us to

Static calls are a replacement for global function pointers. They use
code patching to allow direct calls to be used instead of indirect
calls. They give the flexibility of function pointers, but with
improved performance. This is especially important for cases where
From: Josh Poimboeuf
Add the inline static call implementation for x86-64. For each key, a
temporary trampoline is created, named __static_call_tramp_. The
trampoline has an indirect jump to the destination function.
Objtool uses the trampoline naming convention to detect all the call
sites.
GCC can turn our static_call(name)(args...) into a tail call, in which
case we get a JMP.d32 into the trampoline (which then does a further
tail-call).
Teach objtool to recognise and mark these in .static_call_sites and
adjust the code patching to deal with this.
