For kernel mappings PAGE_PROTNONE is not necessarily set for a non present
mapping, but the inversion logic explicitely checks for !PRESENT and
PROT_NONE.
Remove the PROT_NONE check and make the inversion unconditional for all not
present mappings.

FSI Updates for 4.19

Pull one final rockchip update from Heiko Stuebner:
pclk_rkpwm_pmu as critical clock, due to it supplying the pwm
used to drive the logic supply of the rk3399 core.

Otherwise cronus putmem fails istep and BML fails to upload skiboot
To do that, we still use our one-page command buffer for small commands
for speed, and for anything bigger, with a limit of 1MB plus a page,
we vmalloc a temporary buffer.
The limit was chosen because Cronus will break up any data transfer
into 1M chunks (the extra page is for the command header).

Notice that in this particular case, I replaced the code comments with
a proper "fall through" annotation, which is what GCC is expecting

When building the VDSO with clang it appears to invoke ld without
specifying endianness, even though clang itself was provided with a -EB
or -EL flag. This results in the build failing due to a mismatch between
the objects that are the input to ld, and the output it is attempting to
create:
VDSO arch/mips/vdso/vdso.so.dbg.raw
mips-linux-ld: arch/mips/vdso/elf.o: compiled for a big endian system
and target is little endian
mips-linux-ld: arch/mips/vdso/elf.o: endianness incompatible with that
of the selected emulation
mips-linux-ld: failed to merge target specific data of file
arch/mips/vdso/elf.o
...
Work around this problem by explicitly specifying the link endianness
using -Wl,-EB or -Wl,-EL when -EB or -EL are part of KBUILD_CFLAGS. This
resolves the build failure when using clang, and doesn't have any
negative effect on gcc.

When building using clang, always specify -EB or -EL in order to ensure
we target the desired endianness.
Since clang cross compiles using a single compiler build with multiple
targets, our -dumpmachine tests which don't specify clang's --target
argument check output based upon the build machine rather than the
machine our build will target. This means our detection of whether to
specify -EB fails miserably & we never do. Providing the endianness flag
unconditionally for clang resolves this issue & simplifies the clang
path somewhat.

gre_multipath test was using egress vlan_id matching on flows, for the
purpose of collecting next-hops statistics, later to be compared
against configured weights.
As matching on vlan_id on egress direction is not supported on all HW
devices, change the match criteria to use destination IP.

llc_sap_put() decreases the refcnt before deleting sap
from the global list. Therefore, there is a chance
llc_sap_find() could find a sap with zero refcnt
in this global list.
Close this race condition by checking if refcnt is zero
or not in llc_sap_find(), if it is zero then it is being
removed so we can just treat it as gone.

Arun Parameswaran says:
====================
Add Broadcom Omega SoC internal switch and phy
The patchset is based on David Miller's "net-next" repo.
The patches add support for the Broadcom Omega SoC's internal ethernet
switch and the internal gphy.
The internal ethernet switch in the Omega is a b53 srab based switch.
The support for the switch is added to the b53 driver in the dsa
framework.
The gphy support is added to the bcm7xxx driver.
