arm, cris, mips, sparc, powerpc, um, xtensa: fix build with bash 4.0

2009-10-22T22:11:51+00:00

commit 51b563fc93c8cb5bff1d67a0a71c374e4a4ea049 upstream.

Albin Tonnerre  reported:

    Bash 4 filters out variables which contain a dot in them.
    This happends to be the case of CPPFLAGS_vmlinux.lds.
    This is rather unfortunate, as it now causes
    build failures when using SHELL=/bin/bash to compile,
    or when bash happens to be used by make (eg when it's /bin/sh)

Remove the common definition of CPPFLAGS_vmlinux.lds by
pushing relevant stuff to either Makefile.build or the
arch specific kernel/Makefile where we build the linker script.

This is also nice cleanup as we move the information out where
it is used.

Notes for the different architectures touched:

arm - we use an already exported symbol
cris - we use a config symbol aleady available
       [Not build tested]
mips - the jiffies complexity has moved to vmlinux.lds.S where we need it.
       Added a few variables to CPPFLAGS - they are only used by
       the linker script.
       [Not build tested]
powerpc - removed assignment that is not needed
          [not build tested]
sparc - simplified it using $(BITS)
um - introduced a few new exported variables to deal with this
xtensa - added options to CPP invocation
         [not build tested]

Remove multiple KERN_ prefixes from printk formats

2009-07-08T17:30:03+00:00

Commit 5fd29d6ccbc98884569d6f3105aeca70858b3e0f ("printk: clean up
handling of log-levels and newlines") changed printk semantics.  printk
lines with multiple KERN_ prefixes are no longer emitted as
before the patch.

 is now included in the output on each additional use.

Remove all uses of multiple KERN_s in formats.

Move FAULT_FLAG_xyz into handle_mm_fault() callers

2009-06-21T20:08:22+00:00

This allows the callers to now pass down the full set of FAULT_FLAG_xyz
flags to handle_mm_fault().  All callers have been (mechanically)
converted to the new calling convention, there's almost certainly room
for architectures to clean up their code and then add FAULT_FLAG_RETRY
when that support is added.

um: remove obsolete hw_interrupt_type

2009-06-17T02:47:47+00:00

The defines and typedefs (hw_interrupt_type, no_irq_type, irq_desc_t) have
been kept around for migration reasons.  After more than two years it's
time to remove them finally.

This patch cleans up one of the remaining users.  When all such patches
hit mainline we can remove the defines and typedefs finally.

Impact: cleanup

Convert the last remaining users to struct irq_chip and remove the
define.

mm: consolidate init_mm definition

2009-06-17T02:47:28+00:00

* create mm/init-mm.c, move init_mm there
* remove INIT_MM, initialize init_mm with C99 initializer
* unexport init_mm on all arches:

  init_mm is already unexported on x86.

  One strange place is some OMAP driver (drivers/video/omap/) which
  won't build modular, but it's already wants get_vm_area() export.
  Somebody should look there.

clocksource: pass clocksource to read() callback

2009-04-21T20:41:47+00:00

Pass clocksource pointer to the read() callback for clocksources.  This
allows us to share the callback between multiple instances.

uml: don't use a too long string literal

2009-04-01T15:59:16+00:00

uml uses a concatenated string literal to store the contents of .config,
but .config file content is varaible, it can be very long.

Use an array of string literals instead.
