When a task which has used the FPU at some point in its past takes a
signal the kernel would previously always require the task to take
ownership of the FPU whilst setting up or restoring from the sigcontext.
That means that if the task has not used the FPU within this timeslice
then the kernel would enable the FPU, restore the task's FP context into
FPU registers and then save them into the sigcontext. This seems
inefficient, and if the signal handler doesn't use FP then enabling the
FPU & the extra memory accesses are entirely wasted work.
This patch modifies the sigcontext setup & restore code to copy directly
between the tasks saved FP context & the sigcontext for any tasks which
have used FP in the past but are not currently the FPU owner (ie. have
not used FP in this timeslice).

These functions aren't directly related to the FPU emulator at all, they
simply copy between a thread's saved context & a sigcontext. Thus move
them to the appropriate signal files & rename them accordingly. This
makes it clearer that the functions don't require the FPU emulator in
any way.

This patch replaces the fpureg_t typedef with a "union fpureg" enabling
easier access to 32 & 64 bit values. This allows the access macros used
in cp1emu.c to be simplified somewhat. It will also make it easier to
expand the width of the FP registers as will be done in a future
patch in order to support the 128 bit registers introduced with MSA.

When userland uses syscall() to perform an indirect system call
the actually system call that needs to be checked by the filter
is on the first argument. The kernel code needs to handle this case
by looking at the original syscall number in v0 and if it's
NR_syscall, then it needs to examine the first argument to
identify the real system call that will be executed.
Similarly, we need to 'virtually' shift the syscall() arguments
so the syscall_get_arguments() function can fetch the correct
arguments for the indirect system call.

the leading underscores from the existing function.
This also makes use of the 'task' argument to determine the type

Commit f55afb0969cc "MIPS: Clean up MIPS MT and CMP configuration
options." introduced a dependency upon MIPS_MT_SMP (ie. SMVP) for the
MIPS_CMP (ie. CMP framework support) Kconfig option. It did not specify
why, and that dependency is bogus. It is perfectly valid to have a
multi-core system with the YAMON bootloader but without MT support -
an example of this would be any multi-core proAptiv bitstream running on
a Malta. Forcing MT support to be enabled in a kernel for such a system
is incorrect. I suspect that the dependency was actually meant to
reflect the fact that YAMON will only bind 1 TC per VPE on an MT system,
and only describe those 1:1 TC:VPE pairs as CPUs through the AMON
interface. Thus an SMTC kernel makes little sense on a system using
MIPS_CMP, and the Kconfig dependencies should reflect that rather than
introducing the bogus SMVP dependency.

net: mvneta: fix usage as a module
The following set of two patches fix the usage of the mvneta driver
when built as a module, and used in RGMII configurations. It is
somewhat similar to a previous fix that was made by Arnaud Patard, but
which was limited to SGMII configurations.
====================

The mvneta driver currently uses of_iomap(), which has two drawbacks:
it doesn't request the resource, and it isn't devm-style so some error
handling is needed.
This commit switches to use devm_ioremap_resource() instead, which
automatically requests the resource (so the I/O registers region shows
up properly in /proc/iomem), and also is devm-style, which allows to
get rid of some error handling to unmap the I/O registers region.

Commit 5445eaf309 ('mvneta: Try to fix mvneta when compiled as
module') fixed the mvneta driver to make it work properly when loaded
as a module in SGMII configuration, which was tested successful by the
author on the Armada XP OpenBlocks AX3, which uses SGMII.
However, it turns out that the Armada XP GP, which uses RGMII, is
affected by a similar problem: its SERDES configuration is lost when
mvneta is loaded as a module, because this configuration is set by the
bootloader, and then lost because the clock is gated by the clock
framework until the mvneta driver is loaded again and the clock is
re-enabled.
However, it turns out that for the RGMII case, setting the SERDES
configuration is not sufficient: the PCS enable bit in the
MVNETA_GMAC_CTRL_2 register must also be set, like in the SGMII
configuration.
Therefore, this commit reworks the SGMII/RGMII initialization: the
only difference between the two now is a different SERDES
configuration, all the rest is identical.
In detail, to achieve this, the commit:
* Renames MVNETA_SGMII_SERDES_CFG to MVNETA_SERDES_CFG because it is
not specific to SGMII, but also used on RGMII configurations.
* Adds a MVNETA_RGMII_SERDES_PROTO definition, that must be used as
the MVNETA_SERDES_CFG value in RGMII configurations.
* Removes the mvneta_gmac_rgmii_set() and mvneta_port_sgmii_config()
functions, and instead directly do the SGMII/RGMII configuration in
mvneta_port_up(), from where those functions where called. It is
worth mentioning that mvneta_gmac_rgmii_set() had an 'enable'
parameter that was always passed as '1', so it was pretty useless.
* Reworks the mvneta_port_up() function to set the MVNETA_SERDES_CFG
register to the appropriate value depending on the RGMII vs. SGMII
configuration. It also unconditionally set the PCS_ENABLE bit (was
already done for SGMII, but is now also needed for RGMII), and sets
the PORT_RGMII bit (which was already done for both SGMII and
RGMII).
This commit was successfully tested with mvneta compiled as a module,
on both the OpenBlocks AX3 (SGMII configuration) and the Armada XP GP
(RGMII configuration).

The cypress PS/2 trackpad models supported by the cypress_ps2 driver
emulate BTN_RIGHT events in firmware based on the finger position, as part
of this no motion events are sent when the finger is in the button area.
The INPUT_PROP_BUTTONPAD property is there to indicate to userspace that
BTN_RIGHT events should be emulated in userspace, which is not necessary
in this case.
When INPUT_PROP_BUTTONPAD is advertised userspace will wait for a motion
event before propagating the button event higher up the stack, as it needs
current abs x + y data for its BTN_RIGHT emulation. Since in the
cypress_ps2 pads don't report motion events in the button area, this means
that clicks in the button area end up being ignored, so
INPUT_PROP_BUTTONPAD actually causes problems for these touchpads, and
removing it fixes:

Since the early days TX stops if there isn't enough free pending slots to
consume a maximum sized (slot-wise) packet. Probably the reason for that is to
avoid the case when we don't have enough free pending slot in the ring to finish
the packet. But if we make sure that the pending ring has the same size as the
shared ring, that shouldn't really happen. The frontend can only post packets
which fit the to the free space of the shared ring. If it doesn't, the frontend
has to stop, as it can only increase the req_prod when the whole packet fits
onto the ring.
This patch avoid using this checking, makes sure the 2 ring has the same size,
and remove a checking from the callback. As now we don't stop the NAPI instance
on this condition, we don't have to wake it up if we free pending slots up.
