cpu-sh4a headers take priority over cpu-sh4 ones by virtue of the build
system, there's no need to try and mingle sh4a stuff in cpu-sh4.

With the previous attempt reverted this switches to conditionalizing the
end address. Nominally VMALLOC_END, but extended for P3_ADDR_MAX in the
store queue case.

This reverts commit 20e7c297efeca0861adcca073a0d283da659834b.
With store queues enabled the area above P4SEG has special properties
from the MMU's point of view, which was causing fixmap failure. We'll
have to do something else to satisfy the vmalloc range check.

In doing the evt2irq() + muxed vector conversion for various port types
it became apparent that some of the legacy port types will presently
error out due to the irq requesting logic attempting to acquire the
non-existent BRI IRQ. This adds some sanity checks to the request/free
path to ensure that non-existence of a source in itself is not an error.
This should restore functionality for legacy PORT_SCI ports.

Pull two networking fixes from David S. Miller:
1) Thanks to Willy Tarreau and Eric Dumazet, we've unlocked a bug that's
been present in do_tcp_sendpages() since that function was written in
2002.
When we block to wait for memory we have to unconditionally try and
push out pending TCP data, otherwise we can block for an unreasonably
long amount of time.
2) Fix deadlock in e1000, fixes kernel bugzilla 43132
From Tushar Dave.

Commit 1cc0c998fdf2 ("ACPI: Fix D3hot v D3cold confusion") introduced a
bug in __acpi_bus_set_power() and changed the behavior of
acpi_pci_set_power_state() in such a way that it generally doesn't work
as expected if PCI_D3hot is passed to it as the second argument.
First off, if ACPI_STATE_D3 (equal to ACPI_STATE_D3_COLD) is passed to
__acpi_bus_set_power() and the explicit_set flag is set for the D3cold
state, the function will try to execute AML method called "_PS4", which
doesn't exist.
Fix this by adding a check to ensure that the name of the AML method
to execute for transitions to ACPI_STATE_D3_COLD is correct in
__acpi_bus_set_power(). Also make sure that the explicit_set flag
for ACPI_STATE_D3_COLD will be set if _PS3 is present and modify
acpi_power_transition() to avoid accessing power resources for
ACPI_STATE_D3_COLD, because they don't exist.
Second, if PCI_D3hot is passed to acpi_pci_set_power_state() as the
target state, the function will request a transition to
ACPI_STATE_D3_HOT instead of ACPI_STATE_D3. However,
ACPI_STATE_D3_HOT is now only marked as supported if the _PR3 AML
method is defined for the given device, which is rare. This causes
problems to happen on systems where devices were successfully put
into ACPI D3 by pci_set_power_state(PCI_D3hot) which doesn't work
now. In particular, some unused graphics adapters are not turned
off as a result.
To fix this issue restore the old behavior of
acpi_pci_set_power_state(), which is to request a transition to
ACPI_STATE_D3 (equal to ACPI_STATE_D3_COLD) if either PCI_D3hot or
PCI_D3cold is passed to it as the argument.
This approach is not ideal, because generally power should not
be removed from devices if PCI_D3hot is the target power state,
but since this behavior is relied on, we have no choice but to
restore it at the moment and spend more time on designing a
better solution in the future.

Since recent changes on TCP splicing (starting with commits 2f533844
"tcp: allow splice() to build full TSO packets" and 35f9c09f "tcp:
tcp_sendpages() should call tcp_push() once"), I started seeing
massive stalls when forwarding traffic between two sockets using
splice() when pipe buffers were larger than socket buffers.
Latest changes (net: netdev_alloc_skb() use build_skb()) made the
problem even more apparent.
The reason seems to be that if do_tcp_sendpages() fails on out of memory
condition without being able to send at least one byte, tcp_push() is not
called and the buffers cannot be flushed.
After applying the attached patch, I cannot reproduce the stalls at all
and the data rate it perfectly stable and steady under any condition
which previously caused the problem to be permanent.
The issue seems to have been there since before the kernel migrated to
git, which makes me think that the stalls I occasionally experienced
with tux during stress-tests years ago were probably related to the
same issue.
This issue was first encountered on 3.0.31 and 3.2.17, so please backport
to -stable.

Pull two more target-core updates from Nicholas Bellinger:
"The first patch addresses a SPC-2 reservations RELEASE bug in a
special (iscsi specific) multi-ISID setup case that was allowing the
same initiator to be able to incorrect release it's own reservation on
a different SCSI path with enforce_pr_isid=1 operation. This bug was
caught by Bernhard Kohl.
The second patch is to address a bug with FILEIO backends where the
incorrect number of blocks for READ_CAPACITY was being reported after
an underlying device-mapper block_device size change. This patch uses
now i_size_read() in fd_get_blocks() for FILEIO backends with an
underlying block_device, instead of trying to determine this value at
setup time during fd_create_virtdevice(). (hch CC'ed)
Both are CC'ed to stable."
* '3.4-urgent' of git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending:
target: Fix bug in handling of FILEIO + block_device resize ops
target: Fix SPC-2 RELEASE bug for multi-session iSCSI client setups
|
|
This patch fixes a bug in the handling of FILEIO w/ underlying block_device
resize operations where the original fd_dev->fd_dev_size was incorrectly being
used in fd_get_blocks() for READ_CAPACITY response payloads.
This patch avoids using fd_dev->fd_dev_size for FILEIO devices with
an underlying block_device, and instead changes fd_get_blocks() to
get the sector count directly from i_size_read() as recommended by hch.
