PCI: fix offset check for sysfs mmapped files
I just loaded 2.6.37-rc2 on my machines, and I noticed that X no longer starts.
Running an strace of the X server shows that it's doing this:
open("/sys/bus/pci/devices/0000:07:00.0/resource0", O_RDWR) = 10
mmap(NULL,
16777216, PROT_READ|PROT_WRITE, MAP_SHARED, 10, 0) = -1 EINVAL (Invalid argument)
This code seems to be asking for a shared read/write mapping of 16MB worth of
BAR0 starting at file offset 0, and letting the kernel assign a starting
address. Unfortunately, this -EINVAL causes X not to start. Looking into
dmesg, there's a complaint like so:
process "Xorg" tried to map 0x01000000 bytes at page 0x00000000 on 0000:07:00.0 BAR 0 (start 0x
96000000, size 0x
1000000)
...with the following code in pci_mmap_fits:
pci_start = (mmap_api == PCI_MMAP_SYSFS) ?
pci_resource_start(pdev, resno) >> PAGE_SHIFT : 0;
if (start >= pci_start && start < pci_start + size &&
start + nr <= pci_start + size)
It looks like the logic here is set up such that when the mmap call comes via
sysfs, the check in pci_mmap_fits wants vma->vm_pgoff to be between the
resource's start and end address, and the end of the vma to be no farther than
the end. However, the sysfs PCI resource files always start at offset zero,
which means that this test always fails for programs that mmap the sysfs files.
Given the comment in the original commit
3b519e4ea618b6943a82931630872907f9ac2c2b, I _think_ the old procfs files
require that the file offset be equal to the resource's base address when
mmapping.
I think what we want here is for pci_start to be 0 when mmap_api ==
PCI_MMAP_PROCFS. The following patch makes that change, after which the Matrox
and Mach64 X drivers work again.

The addition of CONFIG_SECURITY_DMESG_RESTRICT resulted in a build

The patch here fixes this by moving the capabilities checks out of the

Fix gcc 4.5.1 miscompiling drivers/char/i8k.c (again)
The fix in commit
6b4e81db2552 ("i8k: Tell gcc that *regs gets
clobbered") to work around the gcc miscompiling i8k.c to add "+m
(*regs)" caused register pressure problems and a build failure.
Changing the 'asm' statement to 'asm volatile' instead should prevent
that and works around the gcc bug as well, so we can remove the "+m".
[ Background on the gcc bug: a memory clobber fails to mark the function
the asm resides in as non-pure (aka "__attribute__((const))"), so if
the function does nothing else that triggers the non-pure logic, gcc
will think that that function has no side effects at all. As a result,
callers will be mis-compiled.
Adding the "+m" made gcc see that it's not a pure function, and so
does "asm volatile". The problem was never really the need to mark
"*regs" as changed, since the memory clobber did that part - the
problem was just a bug in the gcc "pure" function analysis - Linus ]

GFS2: Fix inode deallocation race
This area of the code has always been a bit delicate due to the
subtleties of lock ordering. The problem is that for "normal"
alloc/dealloc, we always grab the inode locks first and the rgrp lock
later.
In order to ensure no races in looking up the unlinked, but still
allocated inodes, we need to hold the rgrp lock when we do the lookup,
which means that we can't take the inode glock.
The solution is to borrow the technique already used by NFS to solve
what is essentially the same problem (given an inode number, look up
the inode carefully, checking that it really is in the expected
state).
We cannot do that directly from the allocation code (lock ordering
again) so we give the job to the pre-existing delete workqueue and
carry on with the allocation as normal.
If we find there is no space, we do a journal flush (required anyway
if space from a deallocation is to be released) which should block
against the pending deallocations, so we should always get the space
back.

ipv6: addrconf: don't remove address state on ifdown if the address is being kept
Currently, addrconf_ifdown does not delete statically configured IPv6
addresses when the interface is brought down. The intent is that when
the interface comes back up the address will be usable again. However,
this doesn't actually work, because the system stops listening on the
corresponding solicited-node multicast address, so the address cannot
respond to neighbor solicitations and thus receive traffic. Also, the
code notifies the rest of the system that the address is being deleted
(e.g, RTM_DELADDR), even though it is not. Fix it so that none of this
state is updated if the address is being kept on the interface.
Tested: Added a statically configured IPv6 address to an interface,
started ping, brought link down, brought link up again. When link came
up ping kept on going and "ip -6 maddr" showed that the host was still
subscribed to there

cause the checksum to be not computed correctly, even though the
hardware is capable of looking inside vlan tags. Instead,
look inside the header if necessary to determine the correct
protocol type.
To some extent this fixes a regression from 2.6.36 because it
was previously not possible to disable vlan offloading and this
error case was not exposed.

The reason appears to be ucc_geth_stop meets adjust_link as the
PHY reports PHY changes. I belive adjust_link hangs somewhere,
holding the PHY lock, because ucc_geth_stop disabled the
controller HW.
Fix is to stop the PHY before disabling the controller.

PCI: fix pci_bus_alloc_resource() hang, prefer positive decode
When a PCI bus has two resources with the same start/end, e.g.,
pci_bus 0000:04: resource 2 [mem 0xd0000000-0xd7ffffff pref]
pci_bus 0000:04: resource 7 [mem 0xd0000000-0xd7ffffff]
the previous pci_bus_find_resource_prev() implementation would alternate
between them forever:
pci_bus_find_resource_prev(... [mem 0xd0000000-0xd7ffffff pref])
returns [mem 0xd0000000-0xd7ffffff]
pci_bus_find_resource_prev(... [mem 0xd0000000-0xd7ffffff])
returns [mem 0xd0000000-0xd7ffffff pref]
pci_bus_find_resource_prev(... [mem 0xd0000000-0xd7ffffff pref])
returns [mem 0xd0000000-0xd7ffffff]
...
This happened because there was no ordering between two resources with the
same start and end. A resource that had the same start and end as the
cursor, but was not itself the cursor, was considered to be before the
cursor.
This patch fixes the hang by making a fixed ordering between any two
resources.
In addition, it tries to allocate from positively decoded regions before
using any subtractively decoded resources. This means we will use a
positive decode region before a subtractive decode one, even if it means
using a smaller address.

backlight: add low threshold to pwm backlight
The intensity of the backlight can be varied from a range of
max_brightness to zero. Though most, if not all the pwm based backlight
devices start flickering at lower brightness value. And also for each
device there exists a brightness value below which the backlight appears
to be turned off though the value is not equal to zero.
If the range of brightness for a device is from zero to max_brightness. A
graph is plotted for brightness Vs intensity for the pwm based backlight
device has to be a linear graph.
intensity
| /
| /
| /
|/
---------
0 max_brightness
But pratically on measuring the above we note that the intensity of
backlight goes to zero(OFF) when the value in not zero almost nearing to
zero(some x%). so the graph looks like
intensity
| /
| /
| /
| |
------------
0 x max_brightness
In order to overcome this drawback knowing this x% i.e nothing but the low
threshold beyond which the backlight is off and will have no effect, the
brightness value is being offset by the low threshold value(retaining the
linearity of the graph). Now the graph becomes
intensity
| /
| /
| /
| /
-------------
0 max_brightness
With this for each and every digit increment in the brightness from zero
there is a change in the intensity of backlight. Devices having this
behaviour can set the low threshold brightness(lth_brightness) and pass
the same as platform data else can have it as zero.
