acpi_tb_install_standard_table().
ACPICA commit c70434d4da13e65b6163c79a5aa16b40193631c7
ACPI_MTX_TABLES is acquired and released by the callers of
acpi_tb_install_standard_table() so releasing it in the function itself is
causing the following error in Linux kernel if the table is reloaded:
ACPI Error: Mutex [0x2] is not acquired, cannot release (20141107/utmutex-321)
Call Trace:
[<ffffffff81b0bd48>] dump_stack+0x4f/0x7b

ACPICA commit aacf863cfffd46338e268b7415f7435cae93b451
It is reported that on a physically 64-bit addressed machine, 32-bit kernel
can trigger crashes in accessing the memory regions that are beyond the
32-bit boundary. The region field's start address should still be 32-bit
compliant, but after a calculation (adding some offsets), it may exceed the
32-bit boundary. This case is rare and buggy, but there are real BIOSes
leaked with such issues (see References below).
This patch fixes this gap by always defining IO addresses as 64-bit, and
allows OSPMs to optimize it for a real 32-bit machine to reduce the size of
the internal objects.
Internal acpi_physical_address usages in the structures that can be fixed
by this change include:
1. struct acpi_object_region:
acpi_physical_address address;
2. struct acpi_address_range:
acpi_physical_address start_address;
acpi_physical_address end_address;
3. struct acpi_mem_space_context;
acpi_physical_address address;
4. struct acpi_table_desc
acpi_physical_address address;
See known issues 1 for other usages.
Note that acpi_io_address which is used for ACPI_PROCESSOR may also suffer
from same problem, so this patch changes it accordingly.
For iasl, it will enforce acpi_physical_address as 32-bit to generate
32-bit OSPM compatible tables on 32-bit platforms, we need to define
ACPI_32BIT_PHYSICAL_ADDRESS for it in acenv.h.
Known issues:
1. Cleanup of mapped virtual address
In struct acpi_mem_space_context, acpi_physical_address is used as a virtual
address:
acpi_physical_address mapped_physical_address;
It is better to introduce acpi_virtual_address or use acpi_size instead.
This patch doesn't make such a change. Because this should be done along
with a change to acpi_os_map_memory()/acpi_os_unmap_memory().
There should be no functional problem to leave this unchanged except
that only this structure is enlarged unexpectedly.

ACPICA commit b60612373a4ef63b64a57c124576d7ddb6d8efb6
For physical addresses, since the address may exceed 32-bit address range
after calculation, we should use 0x%8.8X%8.8X instead of ACPI_PRINTF_UINT
and ACPI_FORMAT_UINT64() instead of
ACPI_FORMAT_NATIVE_UINT()/ACPI_FORMAT_TO_UINT().
This patch also removes above replaced macros as there are no users.
This is a preparation to switch acpi_physical_address to 64-bit on 32-bit
kernel builds.

ACPI_PHYSADDR_TO_PTR()/ACPI_PTR_TO_PHYSADDR().
ACPICA commit 154f6d074dd38d6ebc0467ad454454e6c5c9ecdf
There are code pieces converting pointers using "(acpi_physical_address) x"
or "ACPI_CAST_PTR (t, x)" formats, this patch cleans up them.
Known issues:
1. Cleanup of "(ACPI_PHYSICAL_ADDRRESS) x" for a table field
For the conversions around the table fields, it is better to fix it with
alignment also fixed. So this patch doesn't modify such code. There
should be no functional problem by leaving them unchanged.

Some HD-A codecs may add their own vendor 'set' verb to the regmap, thru func
snd_hdac_add_vendor_verb(). This patch sets the GET bit (bit 11) when adding
the verb so that its peer vendor 'get' verb is actually added. This can avoid
I/O error when writing the 'set' verb thru remap, since HD-A regmap internally
looks up a writable vendor verb with GET bit set at first.

either have:
- a kernel bug
- some sort of hypervisor misconfiguration
- ENOMEM

For hypervisor errors, EIO is used so there is something reported

git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs
Al Viro says:
====================
netdev-related stuff in vfs.git
There are several commits sitting in vfs.git that probably ought to go in
via net-next.git. First of all, there's merge with vfs.git#iocb - that's
Christoph's aio rework, which has triggered conflicts with the ->sendmsg()
and ->recvmsg() patches a while ago. It's not so much Christoph's stuff
that ought to be in net-next, as (pretty simple) conflict resolution on merge.
The next chunk is switch to {compat_,}import_iovec/import_single_range - new
safer primitives for initializing iov_iter. The primitives themselves come
from vfs/git#iov_iter (and they are used quite a lot in vfs part of queue),
conversion of net/socket.c syscalls belongs in net-next, IMO. Next there's
afs and rxrpc stuff from dhowells. And then there's sanitizing kernel_sendmsg
et.al. + missing inlined helper for "how much data is left in msg->msg_iter" -
this stuff is used in e.g. cifs stuff, but it belongs in net-next.
That pile is pullable from
git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs.git for-davem
I'll post the individual patches in there in followups; could you take a look
and tell if everything in there is OK with you?

Pull regulator updates from Mark Brown:
"Another release, another set of regulator updates. Not much of it is
showing up in the code yet but there's been a lot of discussion going
on about how to enhance the regulator API to work better with modern
SoCs which have a microcontroller sitting between Linux and the
hardware.
I'm hopeful that'll start to come through into mainline for v4.2 but
it's not quite there for v4.1 - what we do have (along with the usual
small updates is) is:
- work from Bjorn Andersson on refactoring the configuration of
regulator loading interfaces to be useful for use with
microcontrollers, the existing interfaces were never actually
useful for anything as-is since nobody was willing to put enough
data into public code.
- a summary tree display in debugfs from Heiko Stübner.
- support for act6000 regulators"

Using a timer wheel for timewait sockets was nice ~15 years ago when
memory was expensive and machines had a single processor.
This does not scale, code is ugly and source of huge latencies
(Typically 30 ms have been seen, cpus spinning on death_lock spinlock.)
We can afford to use an extra 64 bytes per timewait sock and spread
timewait load to all cpus to have better behavior.
Tested:
On following test, /proc/sys/net/ipv4/tcp_tw_recycle is set to 1
on the target (lpaa24)
Before patch :
lpaa23:~# ./super_netperf 200 -H lpaa24 -t TCP_CC -l 60 -- -p0,0
419594
lpaa23:~# ./super_netperf 200 -H lpaa24 -t TCP_CC -l 60 -- -p0,0
437171
While test is running, we can observe 25 or even 33 ms latencies.
lpaa24:~# ping -c 1000 -i 0.02 -qn lpaa23
...
1000 packets transmitted, 1000 received, 0% packet loss, time 20601ms
rtt min/avg/max/mdev = 0.020/0.217/25.771/1.535 ms, pipe 2
lpaa24:~# ping -c 1000 -i 0.02 -qn lpaa23
...
1000 packets transmitted, 1000 received, 0% packet loss, time 20702ms
rtt min/avg/max/mdev = 0.019/0.183/33.761/1.441 ms, pipe 2
After patch :
About 90% increase of throughput :
lpaa23:~# ./super_netperf 200 -H lpaa24 -t TCP_CC -l 60 -- -p0,0
810442
lpaa23:~# ./super_netperf 200 -H lpaa24 -t TCP_CC -l 60 -- -p0,0
800992
And latencies are kept to minimal values during this load, even
if network utilization is 90% higher :
lpaa24:~# ping -c 1000 -i 0.02 -qn lpaa23
...
1000 packets transmitted, 1000 received, 0% packet loss, time 19991ms
rtt min/avg/max/mdev = 0.023/0.064/0.360/0.042 ms
