Add PIIX4 APCI quirk for the 440MX chipset too
This is confirmed to fix a hang due to PCI resource conflicts with
setting up the Cardbus bridge on old laptops with the 440MX chipsets.
Original report by Alessio Sangalli, lspci debugging help by Pekka
Enberg, and trial patch suggested by Daniel Ritz:
"From the docs available i would _guess_ this thing is really similar
to the 82443BX/
82371AB combination. at least the SMBus base address
register is hidden at the very same place (32bit at 0x90 in function
3 of the "south" brigde)"
The dang thing is largely undocumented, but the patch was corroborated
by Asit Mallick:
"I am trying to find the register information. 440MX is an integration of
440BX north-bridge without AGP and PIIX4E (
82371EB). PIIX4 quirk
should cover the ACPI and SMBus related I/O registers."

[PATCH] x86_64: Bring x86-64 ia32 emul in sync with i386 on READ_IMPLIES_EXEC enabling
Currently ia32 binaries behave differently with respect to enabling
READ_IMPLIES_EXEC. On i386 a binary with the exec_stack flag set is
executed with READ_IMPLIES_EXEC enabled as well. The same binary
executes without READ_IMPLIES_EXEC on x86-64.
This causes binaries that work on i386 to fail on x86-64 which goes
somewhat against the whole 32 bit emulation idea.
It has been argued that READ_IMPLIES_EXEC should not be enabled at all
for binaries that have the exec_stack flag. Which is probably a valid
point. However until this is clarified I think x86-64 should behave the
same for ia32 binaries as i386.

tainting-condition. The goal is to not get weird lockdep traces that don't
make sense or are otherwise undebuggable, to not waste time.
Lockdep assumes that the previous state it knows about is valid to operate,
which is why lockdep turns itself off after the first violation it reports,
after that point it can no longer make that assumption.
A kernel oops means that the integrity of the kernel compromised; in
addition anything lockdep would report is of lesser importance than the
oops.
All the tainting conditions are of similar integrity-violating nature and

[PATCH] make valid_mmap_phys_addr_range() take a pfn
Newer ARMs have a 40 bit physical address space, but mapping physical
memory above 4G needs a special page table format which we (currently?) do
not use for userspace mappings, so what happens instead is that mapping an
address >= 4G will happily discard the upper bits and wrap.
There is a valid_mmap_phys_addr_range() arch hook where we could check for
>= 4G addresses and deny the mapping, but this hook takes an unsigned long
address:
static inline int valid_mmap_phys_addr_range(unsigned long addr, size_t size);
And drivers/char/mem.c:mmap_mem() calls it like this:
static int mmap_mem(struct file * file, struct vm_area_struct * vma)
{
size_t size = vma->vm_end - vma->vm_start;
if (!valid_mmap_phys_addr_range(vma->vm_pgoff << PAGE_SHIFT, size))
So that's not much help either.
This patch makes the hook take a pfn instead of a phys address.

[PATCH] Fix and enable EDAC sysfs operation
When EDAC was first introduced into the kernel it had a sysfs interface,
but due to some problems it was disabled in 2.6.16 and remained disabled in
2.6.17.
With feedback, several of the control and attribute files of that interface
had some good constructive feedback. PCI Blacklist/Whitelist was a major
set which has design issues and it has been removed in this patch. Instead
of storing PCI broken parity status in EDAC, it has been moved to the
pci_dev structure itself by a previous PCI patch. A future patch will
enable that feature in EDAC by utilizing the pci_dev info.
The sysfs is now enabled in this patch, with a minimal set of control and
attribute files for examining EDAC state and for enabling/disabling the
memory and PCI operations.
The Documentation for EDAC has also been updated to reflect the new state
of EDAC operation.

[PATCH] FDPIC: Adjust the ELF-FDPIC driver to conform more to the CodingStyle
Adjust the ELF-FDPIC binfmt driver to conform much more to the CodingStyle,
silly though it may be.
Further changes:
(*) Drop the casts to long for addresses in kdebug() statements (they're
unsigned long already).
(*) Use extra variables to avoid expressions longer than 80 chars by splitting
the statement into multiple statements and letting the compiler optimise
them back together.
(*) Eliminate duplicate call of ksize() when working out how much space was
actually allocated for the stack.
(*) Discard the commented-out load_shlib prototype and op pointer as this will
not be supported in ELF-FDPIC for the foreseeable future.

[PATCH] NOMMU: Fix execution off of ramfs with mmap()
Fix execution through the FDPIC binfmt of programs stored on ramfs by
preventing the ramfs mmap() returning successfully on a private mapping of
a ramfs file. This causes NOMMU mmap to make a copy of the mapped portion
of the file and map that instead.
This could be improved by granting direct mapping access to read-only
private mappings for which the data is stored on a contiguous run of pages.
However, this is only likely to be the case if the file was extended with
truncate before being written.
ramfs is left to map the file directly for shared mappings so that SYSV IPC
and POSIX shared memory both still work.

[PATCH] mmap zero-length hugetlb file with PROT_NONE to protect a hugetlb virtual area
Sometimes, applications need below call to be successful although
"/mnt/hugepages/file1" doesn't exist.
fd = open("/mnt/hugepages/file1", O_CREAT|O_RDWR, 0755);
*addr = mmap(NULL, 0x1024*1024*256, PROT_NONE, 0, fd, 0);
As for regular pages (or files), above call does work, but as for huge
pages, above call would fail because hugetlbfs_file_mmap would fail if
(!(vma->vm_flags & VM_WRITE) && len > inode->i_size).
This capability on huge page is useful on ia64 when the process wants to
protect one area on region 4, so other threads couldn't read/write this
area. A famous JVM (Java Virtual Machine) implementation on IA64 needs the
capability.

We all failed to notice that Franck's recent update to usb-storage allowed

Although timeouts in usb-storage are relatively uncommon, they do occur.
Without this patch the code in 2.6.18-rc1 will fault within an interrupt

[PATCH] pci: initialize struct pci_dev.error_state
The pci channel state is currently uninitialized, thus there are two ways
of indicating that "everything's OK": 0 and 1. This is a bit of a burden.
If a devce driver wants to check if the pci channel is in a working or a
disconnected state, the driver writer must perform checks similar to
if((pdev->error_state != 0) &&
(pdev->error_state != pci_channel_io_normal)) {
whatever();
}
which is rather akward. The first check is needed because stuct pci_dev is
inited to all-zeros. The scond is needed because the error recovery will
set the state to pci_channel_io_normal (which is not zero).
This patch fixes this awkwardness.

[PATCH] powerpc: fix trigger handling in the new irq code
This patch slightly reworks the new irq code to fix a small design error. I
removed the passing of the trigger to the map() calls entirely, it was not a
good idea to have one call do two different things. It also fixes a couple of
corner cases.
Mapping a linux virtual irq to a physical irq now does only that. Setting the
trigger is a different action which has a different call.
The main changes are:
- I no longer call host->ops->map() for an already mapped irq, I just return
the virtual number that was already mapped. It was called before to give an
opportunity to change the trigger, but that was causing issues as that could
happen while the interrupt was in use by a device, and because of the
trigger change, map would potentially muck around with things in a racy way.
That was causing much burden on a given's controller implementation of
map() to get it right. This is much simpler now. map() is only called on
the initial mapping of an irq, meaning that you know that this irq is _not_
being used. You can initialize the hardware if you want (though you don't
have to).
- Controllers that can handle different type of triggers (level/edge/etc...)
now implement the standard irq_chip->set_type() call as defined by the
generic code. That means that you can use the standard set_irq_type() to
configure an irq line manually if you wish or (though I don't like that
interface), pass explicit trigger flags to request_irq() as defined by the
generic kernel interfaces. Also, using those interfaces guarantees that
your controller set_type callback is called with the descriptor lock held,
thus providing locking against activity on the same interrupt (including
mask/unmask/etc...) automatically. A result is that, for example, MPIC's
own map() implementation calls irq_set_type(NONE) to configure the hardware
to the default triggers.
- To allow the above, the irq_map array entry for the new mapped interrupt
is now set before map() callback is called for the controller.
- The irq_create_of_mapping() (also used by irq_of_parse_and_map()) function
for mapping interrupts from the device-tree now also call the separate
set_irq_type(), and only does so if there is a change in the trigger type.
- While I was at it, I changed pci_read_irq_line() (which is the helper I
would expect most archs to use in their pcibios_fixup() to get the PCI
interrupt routing from the device tree) to also handle a fallback when the
DT mapping fails consisting of reading the PCI_INTERRUPT_PIN to know wether
the device has an interrupt at all, and the the PCI_INTERRUPT_LINE to get an
interrupt number from the device. That number is then mapped using the
default controller, and the trigger is set to level low. That default
behaviour works for several platforms that don't have a proper interrupt
tree like Pegasos. If it doesn't work for your platform, then either
provide a proper interrupt tree from the firmware so that fallback isn't
needed, or don't call pci_read_irq_line()
- Add back a bit that got dropped by my main rework patch for properly
clearing pending IPIs on pSeries when using a kexec
