This reverts commit cf450136bfde77c7f95065c91bffded4aa7fa731.
It breaks reboot on at least one Thinkpad T43, as reported by Jörg Otte:
"On reboot it shuts down as normal.
The last lines displayed are:
>Unmounting temporary filesystems.. [OK]
>Deactivating swap... [OK]
>Unmounting local filesystems... [OK]
>Will now restart
> Restarting system
Then I hear it accessing the cd-drive, but then it's being stuck."
Jörg bisected the regression to this commit.
That commit fixes another machine (see
https://bugzilla.kernel.org/show_bug.cgi?id=11533
for details) that has a BIOS bug and doesn't support ACPI reset.
However, at least one of those other reporters no longer even has the
machine in question, and had a different workaround to begin with.
Besides, it clearly was a buggy BIOS. Let's not break the correct case
to fix that case.

Commit 24aa07882b ("memblock, x86: Replace memblock_x86_reserve/
free_range() with generic ones") replaced x86 specific memblock
operations with the generic ones; unfortunately, it lost zero length
operation handling in the process making the kernel panic if somebody
tries to reserve zero length area.
There isn't much to be gained by being cranky to zero length operations
and panicking is almost the worst response. Drop the BUG_ON() in
memblock_reserve() and update memblock_add_region/isolate_range() so
that all zero length operations are handled as noops.

When loading symbols from DSO we check multiple paths of DSO binary
until we succeed to load symbols ('.symtab' section). Once symbols are
read we try to load also plt symbols.
During the reading of plt symbols, the dso file is reopened from
location given by dso->long_name. This could be wrong in case we want
process buildid binaries.
The change is to make the plt symbols being read from the DSO path, that
normal symbols were read from.

This loop on EBCISR register was designed to clear IRQ sources before enabling
a DMA channel. This register is clear-on-read so a race condition can appear if
another channel is already active and has just finished its transfer.
Removing this read on EBCISR is fixing the issue as there is no case where an IRQ
could be pending: we already make sure that this register is drained at probe()
time and during resume.

In the recent update of the cifs_iovec_write code to use async writes,
the handling of the file position was broken. That patch added a local
"offset" variable to handle the offset, and then only updated the
original "*poffset" before exiting.
Unfortunately, it copied off the original offset from the beginning,
instead of doing so after generic_write_checks had been called. Fix
this by moving the initialization of "offset" after that in the
function.

the csr clock is not passed from the framework and the Ethernet
device driver is failing when it can work w/o any issues and

step. I have just tested it on ST STiH415 SoC (ARM).

Recently the dma parameters that can be passed from the platform
have been moved from the plat_stmmacenet_data to the stmmac_dma_cfg.
In case of this new structure is not well allocated the driver can
fails. This is an example how this field is managed in ST platforms
static struct stmmac_dma_cfg gmac_dma_setting = {
.pbl = 32,
};
static struct plat_stmmacenet_data stih415_ethernet_platform_data[] = {
{
.dma_cfg = &gmac_dma_setting,
.has_gmac = 1,
[snip]
This patch so verifies that the dma_cfg passed from the platform.
In case of it is NULL there is no reason that the driver has to fail
and some default values can be passed. These are ok for all the
Synopsys chips and could impact on performances, only.

While debugging a latency with someone on IRC (mirage335) on #linux-rt (OFTC),
we discovered that the stacktrace output of the latency tracers
(preemptirqsoff) was empty.
This bug was caused by the creation of the dynamic length stack trace
again (like commit 12b5da3 "tracing: Fix ent_size in trace output" was).
This bug is caused by the latency tracers requiring the next event
to determine the time between the current event and the next. But by
grabbing the next event, the iter->ent_size is set to the next event
instead of the current one. As the stacktrace event is the last event,
this makes the ent_size zero and causes nothing to be printed for
the stack trace. The dynamic stacktrace uses the ent_size to determine
how much of the stack can be printed. The ent_size of zero means
no stack.
The simple fix is to save the iter->ent_size before finding the next event.
Note, mirage335 asked to remain anonymous from LKML and git, so I will
not add the Reported-by and Tested-by tags, even though he did report
the issue and tested the fix.

Revises routines that deal with connections between two ports on
the same node to ensure the connection is not impacted if the node's
network address is changed in mid-operation. The routines now treat
the default node address of <0.0.0> as an alias for "this node" in
the following situations:
1) Incoming messages destined to a connected port now handle the alias
properly when validating that the message was sent by the expected
peer port, ensuring that the message will be accepted regardless of
whether it specifies the node's old network address or it's current one.
2) The code which completes connection establishment now handles the
alias properly when determining if the peer port is on the same node
as the connected port.
An added benefit of addressing issue 1) is that some peer port
validation code has been relocated to TIPC's socket subsystem, which
means that validation is no longer done twice when a message is
sent to a non-socket port (such as TIPC's configuration service or
network topology service).

Prior to commit 23dd4cce387124ec3ea06ca30d17854ae4d9b772
"tipc: Combine port structure with tipc_port structure"
there was a need for the two sets of helper functions. But
now they are just duplicates. Remove the globally visible
ones, and mark the remaining ones as inline.
