8eba3651f1 MIPS: PCI: fix pcibios_map_irq section mismatch
Drop  the __init from pcibios_map_irq() to make this section mis-
match go away:

WARNING: vmlinux.o(.text+0x56acd4): Section mismatch in reference from the function pcibios_scanbus() to the function .init.text:pcibios_map_irq()
The function pcibios_scanbus() references
the function __init pcibios_map_irq().
This is often because pcibios_scanbus lacks a __init
annotation or the annotation of pcibios_map_irq is wrong.

Run-Tested only on Alchemy.

c22c804310 MIPS: Fix input modify in __write_64bit_c0_split()
The inline asm in __write_64bit_c0_split() modifies the 64-bit input
operand by shifting the high register left by 32, and constructing the
full 64-bit value in the low register (even on a 32-bit kernel), so if
that value is used again it could cause breakage as GCC would assume the
registers haven't changed when they have.

To quote the GCC extended asm documentation:
> Warning: Do not modify the contents of input-only operands (except for

Avoid modifying the input by using a temporary variable as an output
which is modified instead of the input and not otherwise used. The asm
is always __volatile__ so GCC shouldn't optimise it out. The low
register of the temporary output is written before the high register of
the input is read, so we have two constraint alternatives, one where
both use the same registers (for when the input value isn't subsequently
used), and one with an early clobber on the output in case the low
output uses the same register as the high input. This allows the
resulting assembly to remain mostly unchanged.

A diff of a MIPS32r6 kernel reveals only three differences, two in
relation to write_c0_r10k_diag() in cpu_probe() (register allocation
rearranged slightly but otherwise identical), and one in relation to
write_c0_cvmmemctl2() in kvm_vz_local_flush_guesttlb_all(), but the
octeon CPU is only supported on 64-bit kernels where
__write_64bit_c0_split() isn't used so that shouldn't matter in
practice. So there currently doesn't appear to be anything broken by
this bug.

b537ca6fed powerpc/pseries: Fix parent_dn reference leak in add_dt_node()
A reference to the parent device node is held by add_dt_node() for the
node to be added. If the call to dlpar_configure_connector() fails
add_dt_node() returns ENOENT and that reference is not freed.

Add a call to of_node_put(parent_dn) prior to bailing out after a
failed dlpar_configure_connector() call.

087ff6a5ae powerpc/pseries: Fix "OF: ERROR: Bad of_node_put() on /cpus" during DLPAR
Commit 215ee763f8 ("powerpc: pseries: remove dlpar_attach_node
dependency on full path") reworked dlpar_attach_node() to no longer
look up the parent node "/cpus", but instead to have the parent node
passed by the caller in the function parameter list.

As a result dlpar_attach_node() is no longer responsible for freeing
the reference to the parent node. However, commit 215ee763f8 failed
to remove the of_node_put(parent) call in dlpar_attach_node(), or to
take into account that the reference to the parent in the caller
dlpar_cpu_add() needs to be held until after dlpar_attach_node()
returns.

As a result doing repeated cpu add/remove dlpar operations will
eventually result in the following error:

Fix the issue by removing the of_node_put(parent) call from
dlpar_attach_node(), and ensuring that the reference to the parent
node is properly held and released by the caller dlpar_cpu_add().

58aff0af75 ipc/shm: Fix order of parameters when calling copy_compat_shmid_to_user
Commit 553f770ef7 ("ipc: move compat shmctl to native") moved the
compat IPC syscall handling into ipc/shm.c and refactored the struct
accessors in the process. Unfortunately, the call to
copy_compat_shmid_to_user when handling a compat {IPC,SHM}_STAT command
gets the arguments the wrong way round, passing a kernel stack address
as the user buffer (destination) and the user buffer as the kernel stack
address (source).

This patch fixes the parameter ordering so the buffers are accessed
correctly.

Issue is that if the data crosses a page boundary inside a compound

To fix this, compute the order using the head of the compound page and
adjust the offset to be relative to that head.

Jiri Pirko says:

====================
mlxsw: Multicast flood update

Nogah says:

Currently, there are four erroneous flows in MC flood:
1. When MC is disabled it affects only the flood table for unregistered
   MC packets, but packets that match an entry in the MDB are unaffected.
2. When MC is disabled, MC packets are being sent to all the ports in the
   bridge (like BC and link-local MC packets) regardless of the designated
   flag (BR_MCAST_FLAG).
3. When a port is being deleted from a bridge it might remain in the MDB.
4. When MC is enabled packets are flooded to the mrouter ports only if
   they don't match any entry in the MDB, when they should always be
   flooded to them.

What these problems have in common is the discrepancy between how the
hardware handles MDB and mcast flood, and how the driver does it. Each
of these problems needs fixing either in the MDB code, or in mcast flood
code, and some in both.

Patches 1-6 change the way the MDB is handled in the driver to make the
following changes easier.
Patches 7-8 fix problem number 1 by removing the MDB from the HW when MC
is being disabled and restoring it when it is being enabled.
Patches 9-10 fix problem number 2 by offloading the flood table by the
appropriate flag.
Patch 11 fixes problem number 3 by adding MDB flush to the port removal.
Patches 12-14 fix problem number 4 by adding the mrouter ports to every
MDB entry in the HW to mimic the wanted behaviour.
