Binfmt_flat: Add minimum support for the Blackfin relocations

2007-10-03T15:41:43+00:00

Add minimum support for the Blackfin relocations, since we don't have
enough space in each reloc.  The idea is to store a value with one
relocation so that subsequent ones can access it.

Actually, this patch is required for Blackfin.  Currently if BINFMT_FLAT is
enabled, git-tree kernel will fail to compile.

remove unused TIF_NOTIFY_RESUME flag

2007-07-31T22:39:38+00:00

Remove unused TIF_NOTIFY_RESUME flag for all processor architectures.  The
flag was not used excecpt on IA-64 where the patch replaces it with
TIF_PERFMON_WORK.

take declarations of enable_irq() et.al. to linux/interrupt.h

2007-07-22T18:44:00+00:00

Now that the last inlined instances are gone, all that is left to do
is turning disable_irq_nosync on arm26 and m68k from defines to aliases
and we are all set - we can make these externs in linux/interrupt.h
uncoditional and kill remaining instances in asm/irq.h

arch: personality independent stack top

2007-07-19T17:04:45+00:00

New arch macro STACK_TOP_MAX it gives the larges valid stack address for the
architecture in question.

It differs from STACK_TOP in that it will not distinguish between
personalities but will always return the largest possible address.

This is used to create the initial stack on execve, which we will move down to
the proper location once the binfmt code has figured out where that is.

fbdev: detect primary display device

2007-07-17T17:23:11+00:00

Add function helper, fb_is_primary_device().  Given struct fb_info, it will
return a nonzero value if the device is the primary display.

Currently, only the i386 is supported where the function checks for the
IORESOURCE_ROM_SHADOW flag.

Add __GFP_MOVABLE for callers to flag allocations from high memory that may be migrated

2007-07-17T17:22:59+00:00

It is often known at allocation time whether a page may be migrated or not.
This patch adds a flag called __GFP_MOVABLE and a new mask called
GFP_HIGH_MOVABLE.  Allocations using the __GFP_MOVABLE can be either migrated
using the page migration mechanism or reclaimed by syncing with backing
storage and discarding.

An API function very similar to alloc_zeroed_user_highpage() is added for
__GFP_MOVABLE allocations called alloc_zeroed_user_highpage_movable().  The
flags used by alloc_zeroed_user_highpage() are not changed because it would
change the semantics of an existing API.  After this patch is applied there
are no in-kernel users of alloc_zeroed_user_highpage() so it probably should
be marked deprecated if this patch is merged.

Note that this patch includes a minor cleanup to the use of __GFP_ZERO in
shmem.c to keep all flag modifications to inode->mapping in the
shmem_dir_alloc() helper function.  This clean-up suggestion is courtesy of
Hugh Dickens.

Additional credit goes to Christoph Lameter and Linus Torvalds for shaping the
concept.  Credit to Hugh Dickens for catching issues with shmem swap vector
and ramfs allocations.

dma-mapping: prevent dma dependent code from linking on !HAS_DMA archs

2007-07-16T16:05:45+00:00

Continuing the work started in 411f0f3edc141a582190d3605cadd1d993abb6df ...

This enables code with a dma path, that compiles away, to build without
requiring additional code factoring.  It also prevents code that calls
dma_alloc_coherent and dma_free_coherent from linking whereas previously
the code would hit a BUG() at run time.  Finally, it allows archs that set
!HAS_DMA to delete their asm/dma-mapping.h file.
