Just like commit 4022e7af86, this fixes the fact that
IORING_OP_ACCEPT ends up using get_unused_fd_flags(), which checks
current->signal->rlim[] for limits.
Add an extra argument to __sys_accept4_file() that allows us to pass
in the proper nofile limit, and grab it at request prep time.

Dmitry reports that a test case shows that io_uring isn't honoring a
modified rlimit nofile setting. get_unused_fd_flags() checks the task
signal->rlimi[] for the limits. As this isn't easily inheritable,
provide a __get_unused_fd_flags() that takes the value instead. Then we
can grab it when the request is prepared (from the original task), and
pass that in when we do the async part part of the open.

This soc has two phy's for the pcie one of them using just a different
register for settig it up but sharing all the rest of the config. Until
now we was presenting this schema as three different phy's in the device
tree using the 'phy-cells' node property to discriminate an index and
setting up a complete phy for the dual port index. This sometimes worked
properly but reconfiguring the same registers twice presents sometimes
some unstable pcie links and the ports was not properly being detected.
The problems only appears on hard resets and soft resets was properly
working. Instead of having this schema just set two phy's in the device
ree and use the 'phy-cells' property to say if the port has or not a dual
port. Doing this configuration and set up becomes easier, LOC is decreased
and the behaviour also gets deterministic with properly and stable pcie
links in both hard and soft resets.

Adds Qualcomm 28nm Hi-Speed USB PHY driver support. This PHY is usually
paired with Synopsys DWC3 USB controllers on Qualcomm SoCs.
The PHY can come in two flavours femtoPHY or picoPHY. This commit adds
support for the femtoPHY with the possibility of extending to the picoPHY
with additional future commits. Both PHYs are on a 28 nanometer process
node.
[bod: Updated qcom_snps_hsphy_set_mode to match new method signature
Added disjunct on mode > 0
Removed regulator_set_voltage() in favour of setting floor in dts
Removed 'snps' and from driver name
Extended commit log to mention femtoPHY and picoPHY for future
reference.]

Usually the digital and analog phys use the same reference clock,
but some platforms have two separate reference clocks for each of
them, so add another optional clock to support them.
In order to keep the clock names consistent with PHY IP's, change
the da_ref for analog phy and ref clock for digital phy.

This is used to tune J-K voltage by internal R (resistance), the
range is [0, 31], the resistance value is about 6.9K ohm for 0,

The PCIe PHY initialization requires the attached device to be present,
which is primarily achieved by the PCI controller driver. So move the
logic from init/exit to power_on/power_off.

Since this phy is shared by multiple devices including USB and PCIe,
it is necessary to determine which device use this phy.
This patch adds SoC-dependent functions to determine a device using
this phy.
When there is 'socionext,syscon' property in the pcie-phy node,
the driver calls SoC-dependt function instead of checking .has_syscon
in SoC-dependent data. The function configures the system controller
to use phy for PCIe.

Add legacy SoC support that needs to manage gio clock and reset and to skip
setting unimplemented phy parameters. This supports Pro5.
This specifies only 1 port use because Pro5 doesn't set it in the power-on
