This reverts commit 697ece78f8.
The implementation of SWAP on powerpc requires page protection
bits to not be one of the least significant PTE bits.
Until the SWAP implementation is changed and this requirement voids,
we have to keep at least _PAGE_RW outside of the 3 last bits.
For now, revert to previous PTE bits order. A further rework
may come later.

Quoth the man page:
```
If the tracee was restarted by PTRACE_SYSCALL or PTRACE_SYSEMU, the
tracee enters syscall-enter-stop just prior to entering any system
call (which will not be executed if the restart was using
PTRACE_SYSEMU, regardless of any change made to registers at this
point or how the tracee is restarted after this stop).
```
The parenthetical comment is currently true on x86 and powerpc,
but not currently true on arm64. arm64 re-checks the _TIF_SYSCALL_EMU
flag after the syscall entry ptrace stop. However, at this point,
it reflects which method was used to re-start the syscall
at the entry stop, rather than the method that was used to reach it.
Fix that by recording the original flag before performing the ptrace
stop, bringing the behavior in line with documentation and x86/powerpc.

With certain kernel configurations, the R_390_JMP_SLOT relocation type
might be generated, which is not expected by the KASLR relocation code,
and the kernel stops with the message "Unknown relocation type".
This was found with a zfcpdump kernel config, where CONFIG_MODULES=n
and CONFIG_VFIO=n. In that case, symbol_get() is used on undefined
__weak symbols in virt/kvm/vfio.c, which results in the generation
of R_390_JMP_SLOT relocation types.
Fix this by handling R_390_JMP_SLOT similar to R_390_GLOB_DAT.

On s390, the layout of normal and large ptes (i.e. pmds/puds) differs.
Therefore, set_huge_pte_at() does a conversion from a normal pte to
the corresponding large pmd/pud. So, when converting an empty pte, this
should result in an empty pmd/pud, which would return true for
pmd/pud_none().
However, after conversion we also mark the pmd/pud as large, and
therefore present. For empty ptes, this will result in an empty pmd/pud
that is also marked as large, and pmd/pud_none() would not return true.
There is currently no issue with this behaviour, as set_huge_pte_at()
does not seem to be called for empty ptes. It would be valid though, so
let's fix this by not marking empty ptes as large in set_huge_pte_at().
This was found by testing a patch from from Anshuman Khandual, which is

we should not do that for non-IO commands, as those request complete

It appears that the side effect that starts the shutdown timer was processed
multiple times, which can happen as multiple paths can trigger it. This of
course leads to the BUG halt in add_timer getting called.
Fix seems pretty straightforward, just check before the timer is added if its
already been started. If it has mod the timer instead to min(current
expiration, new expiration)
Its been tested but not confirmed to fix the problem, as the issue has only
occured in production environments where test kernels are enjoined from being
installed. It appears to be a sane fix to me though. Also, recentely,

The whole ethertype filtering code is implemented in igc_ethtool.c and
mixes logic from ethtool and core parts. This patch refactors it so core
logic is moved to igc_main.c, aligning the ethertype filtering code
organization with the rest of the filtering code from the driver (MAC
address and VLAN priority).
Besides moving code to igc_main.c, this patch also does some minor
improvements to the code. Below are some highlights.
In case all filters are already in use and the user tries to add another
filter, we return -ENOSPC instead of -EINVAL so a more meaningful error
code is provided. This also aligns with the behavior implemented in MAC
address filtering code.
With this code refactoring, 'etype_bitmap' array in struct igc_adapter
and 'etype_reg_index' in struct igc_nfc_filter are not needed anymore
and are removed.
Log messages are added to help debugging the ethertype filtering code.

Christoph Hellwig says:
====================
add a new ->ndo_tunnel_ctl method to avoid a few set_fs calls v2
both the ipv4 and ipv6 code have an ioctl each that can be used to create
a tunnel using code that doesn't live in the core kernel or ipv6 module.
Currently they call ioctls on the tunnel devices to create these, for
which the code needs to override the address limit, which is a "feature"
I plan to get rid of.
Instead this patchset adds a new ->ndo_tunnel_ctl that can be used for
the tunnel configuration using struct ip_tunnel_parm. The method is
either invoked from a helper that does the uaccess and can be wired up
as ndo_do_ioctl method, or directly from the magic IPV4/6 ioctls that
create tunnels with kernel space arguments.

The commit 637bc8bbe6 ("inet: reset tb->fastreuseport when adding a reuseport sk")
added a bind-address cache in tb->fast*. The tb->fast* caches the address
of a sk which has successfully been binded with SO_REUSEPORT ON. The idea
is to avoid the expensive conflict search in inet_csk_bind_conflict().
There is an issue with wildcard matching where sk_reuseport_match() should
have returned false but it is currently returning true. It ends up
hiding bind conflict. For example,
bind("[::1]:443"); /* without SO_REUSEPORT. Succeed. */
bind("[::2]:443"); /* with SO_REUSEPORT. Succeed. */
bind("[::]:443"); /* with SO_REUSEPORT. Still Succeed where it shouldn't */
The last bind("[::]:443") with SO_REUSEPORT on should have failed because
it should have a conflict with the very first bind("[::1]:443") which
has SO_REUSEPORT off. However, the address "[::2]" is cached in
tb->fast* in the second bind. In the last bind, the sk_reuseport_match()
returns true because the binding sk's wildcard addr "[::]" matches with
the "[::2]" cached in tb->fast*.
The correct bind conflict is reported by removing the second
bind such that tb->fast* cache is not involved and forces the
bind("[::]:443") to go through the inet_csk_bind_conflict():
bind("[::1]:443"); /* without SO_REUSEPORT. Succeed. */
bind("[::]:443"); /* with SO_REUSEPORT. -EADDRINUSE */
The expected behavior for sk_reuseport_match() is, it should only allow
the "cached" tb->fast* address to be used as a wildcard match but not
the address of the binding sk. To do that, the current
"bool match_wildcard" arg is split into
"bool match_sk1_wildcard" and "bool match_sk2_wildcard".
This change only affects the sk_reuseport_match() which is only
used by inet_csk (e.g. TCP).
The other use cases are calling inet_rcv_saddr_equal() and
this patch makes it pass the same "match_wildcard" arg twice to
the "ipv[46]_rcv_saddr_equal(..., match_wildcard, match_wildcard)".

b9f4c01f3e ("selftest/bpf: Make bpf_iter selftest compilable against old vmlinux.h")
missed the fact that bpf_iter_test_kern{3,4}.c are not just including
bpf_iter_test_kern_common.h and need similar bpf_iter_meta re-definition
explicitly.

====================
net/iucv: updates 2020-05-19
please apply the following patch series for iucv to netdev's net-next
tree.
s390 dropped its support for power management, this removes the relevant
iucv code. Also, some easy cleanups I found mouldering in an old branch.

Remove a bunch of forward declarations (trivially shifting code around
where needed), and make a few functions static.
