arch/tile: avoid build warnings from duplicate ELF_R_xxx #defines

2012-10-23T14:22:48+00:00

These are now provided in , so clean up warnings
by not re-defining them in module.c.

Pull tile arch update from Chris Metcalf:
 "The bulk of this change is the tile uapi disintegration.  There is
  also a one-line change in here to enable interrupts in
  do_work_pending() to avoid a WARN_ON in _local_bh_enable_ip()."

vfs: define struct filename and have getname() return it

2012-10-13T00:14:55+00:00

getname() is intended to copy pathname strings from userspace into a
kernel buffer. The result is just a string in kernel space. It would
however be quite helpful to be able to attach some ancillary info to
the string.

For instance, we could attach some audit-related info to reduce the
amount of audit-related processing needed. When auditing is enabled,
we could also call getname() on the string more than once and not
need to recopy it from userspace.

This patchset converts the getname()/putname() interfaces to return
a struct instead of a string. For now, the struct just tracks the
string in kernel space and the original userland pointer for it.

Later, we'll add other information to the struct as it becomes
convenient.

arch/tile: enable interrupts in do_work_pending()

2012-10-12T19:38:54+00:00

All the called functions expect interrupts to be enabled, and
now one of them has started to warn about it, so make it correct.

compat: move compat_siginfo_t definition to asm/compat.h

2012-10-05T18:05:16+00:00

This is a preparatory patch for the introduction of NT_SIGINFO elf note.

Make the location of compat_siginfo_t uniform across eight architectures
which have it.  Now it can be pulled in by including asm/compat.h or
linux/compat.h.

Most of the copies are verbatim.  compat_uid[32]_t had to be replaced by
__compat_uid[32]_t.  compat_uptr_t had to be moved up before
compat_siginfo_t in asm/compat.h on a several architectures (tile already
had it moved up).  compat_sigval_t had to be relocated from linux/compat.h
to asm/compat.h.

PCI: Provide a default pcibios_update_irq()

2012-09-18T23:28:21+00:00

Most architectures implement this in exactly the same way. Instead of
having each architecture duplicate this function, provide a single
implementation in the core and make it a weak symbol so that it can be
overridden on architectures where it is required.

PCI: Discard __init annotations for pci_fixup_irqs() and related functions

2012-09-18T23:22:25+00:00

Remove the __init annotations in order to keep pci_fixup_irqs() around
after init (e.g. for hotplug). This requires the same change for the
implementation of pcibios_update_irq() on all architectures. While at
it, all __devinit annotations are removed as well, since they will be
useless now that HOTPLUG is always on.
