tile: work around bug in the generic sys_llseek

2013-03-14T18:26:25+00:00

commit 5a114b98661e3aaa0ac085eb931584dce3b0ef9b upstream.

sys_llseek should specify the high and low 32-bit seek values as "unsigned
int" but instead it specifies "unsigned long".  Since compat syscall
arguments are always sign-extended on tile, this means that a seek value
of 0xffffffff will be incorrectly interpreted as a value of -1ULL.

To avoid the risk of breaking binary compatibility on architectures
that already use sys_llseek this way, we follow the same path as MIPS
and provide a wrapper override.

tile: tag some code with #ifdef CONFIG_COMPAT

2013-02-08T18:20:43+00:00

This allows us to disable COMPAT mode without a link error.

tile: fix memcpy_*io functions for allnoconfig

2013-02-08T18:20:40+00:00

On tilepro without CONFIG_PCI, we can't provide inlines of these
functions, as we don't have readl/writel.

In addition, fix memset_io() signature to take a volatile void *.

tile: export a handful of symbols appropriately

2013-02-08T18:20:36+00:00

This was shown up by running with "allmodconfig".  I used
EXPORT_SYMBOL() to match existing conventions in files that
were already exporting symbols, or that were exported that way
by other architectures, and otherwise EXPORT_SYMBOL_GPL().

tile: avoid defining INT_MASK macro in

2013-02-04T17:53:15+00:00

Unfortunately, this name conflicts with a different use of
the name in various places through the tree, so don't provide
it for the kernel.  We preserve it for userspace to avoid
breaking any userspace code that relies on this definition.

This fixes a number of compile errors for various drivers that
are enabled by "allyesconfig".

tile: provide "screen_info" when enabling VT

2013-02-04T17:53:14+00:00

This avoids a link-time failure when building allyesconfig.

tile: include kernel/Kconfig.freezer in tile Kconfig

2013-02-01T16:56:53+00:00

Suggested by Tejun Heo  to fix "allyesconfig"
compile failure.

ARCH: drivers remove __dev* attributes.

2013-01-03T23:57:13+00:00

This fixes up all of the smaller arches that had __dev* markings for
their platform-specific drivers.

CONFIG_HOTPLUG is going away as an option.  As a result, the __dev*
markings need to be removed.

This change removes the use of __devinit, __devexit_p, __devinitdata,
__devinitconst, and __devexit from these drivers.

Based on patches originally written by Bill Pemberton, but redone by me
in order to handle some of the coding style issues better, by hand.

Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/signal

2012-12-21T02:05:28+00:00

Pull signal handling cleanups from Al Viro:
 "sigaltstack infrastructure + conversion for x86, alpha and um,
  COMPAT_SYSCALL_DEFINE infrastructure.

  Note that there are several conflicts between "unify
  SS_ONSTACK/SS_DISABLE definitions" and UAPI patches in mainline;
  resolution is trivial - just remove definitions of SS_ONSTACK and
  SS_DISABLED from arch/*/uapi/asm/signal.h; they are all identical and
  include/uapi/linux/signal.h contains the unified variant."

Fixed up conflicts as per Al.

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/signal:
  alpha: switch to generic sigaltstack
  new helpers: __save_altstack/__compat_save_altstack, switch x86 and um to those
  generic compat_sys_sigaltstack()
  introduce generic sys_sigaltstack(), switch x86 and um to it
  new helper: compat_user_stack_pointer()
  new helper: restore_altstack()
  unify SS_ONSTACK/SS_DISABLE definitions
  new helper: current_user_stack_pointer()
  missing user_stack_pointer() instances
  Bury the conditionals from kernel_thread/kernel_execve series
  COMPAT_SYSCALL_DEFINE: infrastructure
