My fix for a recursive Kconfig dependency caused another issue where the
ACPI specific options end up in the top-level menu in 'menuconfig'. This
was an unintended side-effect of having a silent option between
'menuconfig ACPI' and 'if ACPI'.
Moving the ARCH_SUPPORTS_ACPI symbol ahead of the ACPI menu solves that
problem and restores the previous presentation.

I have encountered an interrupt storm during the eMMC chip probing (and

the SDHI DMA interrupts enabled while the Linux driver didn't use those.
Masking those interrupts in renesas_sdhi_internal_dmac_request_dma() gets

tcp_bbr: PROBE_RTT minor bug fixes
This series includes two minor bug fixes for the TCP BBR PROBE_RTT
mechanism, and one preparatory patch:
(1) A preparatory patch to reorganize the PROBE_RTT logic by refactoring
(into its own function) the code to exit PROBE_RTT, since the next
patch will be using that code in a new context.
(2) Fix: When BBR restarts from idle and if BBR is in PROBE_RTT mode,
BBR should check if it's time to exit PROBE_RTT. If yes, then BBR
should exit PROBE_RTT mode and restore the cwnd to its full value.
(3) Fix: Apply the PROBE_RTT cwnd cap even if the count of fully-ACKed
packets is 0.
====================
Signed-off-by: David S. Miller <davem@davemloft.net>
This commit fixes a corner case where TCP BBR would enter PROBE_RTT
mode but not reduce its cwnd. If a TCP receiver ACKed less than one
full segment, the number of delivered/acked packets was 0, so that
bbr_set_cwnd() would short-circuit and exit early, without cutting
cwnd to the value we want for PROBE_RTT.
The fix is to instead make sure that even when 0 full packets are
ACKed, we do apply all the appropriate caps, including the cap that
applies in PROBE_RTT mode.

tcp uses per-cpu (and per namespace) sockets (net->ipv4.tcp_sk) internally
to send some control packets.
1) RST packets, through tcp_v4_send_reset()
2) ACK packets in SYN-RECV and TIME-WAIT state, through tcp_v4_send_ack()
These packets assert IP_DF, and also use the hashed IP ident generator
to provide an IPv4 ID number.
Geoff Alexander reported this could be used to build off-path attacks.
These packets should not be fragmented, since their size is smaller than
IPV4_MIN_MTU. Only some tunneled paths could eventually have to fragment,
regardless of inner IPID.
We really can use zero IPID, to address the flaw, and as a bonus,
avoid a couple of atomic operations in ip_idents_reserve()

The TC filter flow mapping override completely skipped the call to
cake_hash(); however that meant that the internal state was not being
updated, which ultimately leads to deadlocks in some configurations. Fix
that by passing the overridden flow ID into cake_hash() instead so it can
react appropriately.
In addition, the major number of the class ID can now be set to override
the host mapping in host isolation mode. If both host and flow are
overridden (or if the respective modes are disabled), flow dissection and
hashing will be skipped entirely; otherwise, the hashing will be kept for
the portions that are not set by the filter.

The generic one is defined as

The arch specific one is open coded checking that _PAGE_USER and
_PAGE_WRITE (_PAGE_RW) flags are set, but lacking to check that
_PAGE_RO and _PAGE_PRIVILEGED are unset, leading to a useless test
on targets like the 8xx which defines _PAGE_RW and _PAGE_USER as 0.

Commit cafa0010cd ("Raise the minimum required gcc version to 4.6")
recently exposed a brittle part of the build for supporting non-gcc
compilers.
Both Clang and ICC define __GNUC__, __GNUC_MINOR__, and
__GNUC_PATCHLEVEL__ for quick compatibility with code bases that haven't
added compiler specific checks for __clang__ or __INTEL_COMPILER.
This is brittle, as they happened to get compatibility by posing as a
certain version of GCC. This broke when upgrading the minimal version
of GCC required to build the kernel, to a version above what ICC and
Clang claim to be.
Rather than always including compiler-gcc.h then undefining or
redefining macros in compiler-intel.h or compiler-clang.h, let's
separate out the compiler specific macro definitions into mutually
exclusive headers, do more proper compiler detection, and keep shared
definitions in compiler_types.h.

I've had trouble when operating a multi-homed Linux NFS server with
Kerberos using NFSv4.0. Lately, I've seen my clients reporting
this (and then hanging):
May 9 11:43:26 manet kernel: NFS: NFSv4 callback contains invalid cred
The client-side commit f11b2a1cfb ("nfs4: copy acceptor name from
context to nfs_client") appears to be related, but I suspect this
problem has been going on for some time before that.
RFC 7530 Section 3.3.3 says:
> For Kerberos V5, nfs/hostname would be a server principal in the
> Kerberos Key Distribution Center database. This is the same
> principal the client acquired a GSS-API context for when it issued
> the SETCLIENTID operation ...
In other words, an NFSv4.0 client expects that the server will use
the same GSS principal for callback that the client used to
establish its lease. For example, if the client used the service
principal "nfs@server.domain" to establish its lease, the server
is required to use "nfs@server.domain" when performing NFSv4.0
callback operations.
The Linux NFS server currently does not. It uses a common service
principal for all callback connections. Sometimes this works as
expected, and other times -- for example, when the server is
accessible via multiple hostnames -- it won't work at all.
This patch scrapes the target name from the client credential,
and uses that for the NFSv4.0 callback credential. That should
be correct much more often.

NFSv4.0 callback needs to know the GSS target name the client used
when it established its lease. That information is available from
the GSS context created by gssproxy. Make it available in each
svc_cred.
Note this will also give us access to the real target service
principal name (which is typically "nfs", but spec does not require
that).

A multi-homed NFS server may have more than one "nfs" key in its
keytab. Enable the kernel to pick the key it wants as a machine
credential when establishing a GSS context.
This is useful for GSS-protected NFSv4.0 callbacks, which are
required by RFC 7530 S3.3.3 to use the same principal as the service
principal the client used when establishing its lease.
A complementary modification to rpc.gssd is required to fully enable
this feature.

This has been broken for an embarassingly long time (since v4.4).
Just needs a couple of __init tags on functions to make the sections
match up.

We need to do this inside the loop as well, or we can allow new
IO to supersede previous IO.

We need the memory barrier before checking the list head,
use the appropriate helper for this. The matching queue
side memory barrier is provided by set_current_state().

Pull more parisc updates from Helge Deller:
- fix boot failure of 64-bit kernel. It got broken by the unwind
optimization commit in merge window.
- fix 64-bit userspace support (static 64-bit applications only, e.g.
we don't yet have 64-bit userspace support in glibc).
- consolidate unwind initialization code.
- add machine model description to stack trace.

The writeback thread would exit with a lock held when the cache device
is detached via sysfs interface, fix it by releasing the held lock
before exiting the while-loop.

SWDEV-146499: hang during multi vulkan process testing
cause:
the second frame's PREAMBLE_IB have clear-state
and LOAD actions, those actions ruin the pipeline
that is still doing process in the previous frame's
work-load IB.
fix:
need insert pipeline sync if have context switch for
SRIOV (because only SRIOV will report PREEMPTION flag
to UMD)
