* pxafb: convert fb driver to use ioremap() and __raw_{readl, writel}eric miao2008-04-30
| | | | | | | | | | | | | | | | | | This is part of the effort moving peripheral registers outside of pxa-regs.h, and using ioremap() make it possible the same IP can be re-used on different processors with different registers space As a result, the fixed mapping in pxa_map_io() is removed. The regs-lcd.h can actually moved to where closer to pxafb.c but some of its bit definitions are directly used by various platform code, though this is not a good style.

* pxafb: un-nest pxafb_parse_options() to cleanup the coding style issueeric miao2008-04-30
| | | | | | | | | | | | | pxafb_parse_options() has very long lines exceeding far beyond 80 characters, which makes the function looks bad. Un-nest it into smaller functions and use a temporary string for only what has been overridden instead of the whole dev_info() message to reduce the line a bit more.

| * | ext4: Convert list_for_each_rcu() to list_for_each_entry_rcu()Aneesh Kumar K.V2008-04-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The list_for_each_entry_rcu() primitive should be used instead of list_for_each_rcu(), as the former is easier to use and provides better type safety. http://groups.google.com/group/linux.kernel/browse_thread/thread/45749c83451cebeb/0633a65759ce7713?lnk=raot Signed-off-by: Aneesh Kumar K.V <aneesh.kumar@linux.vnet.ibm.com> Signed-off-by: Roel Kluin <12o3l@tiscali.nl> Signed-off-by: Mingming Cao <cmm@us.ibm.com> Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>
| * | ext4: reduce mballoc stack usage with noinline_for_stackEric Sandeen2008-04-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | mballoc.c is a whole lot of static functions, which gcc seems to really like to inline. With the changes below, on x86, I can at least get from: 432 ext4_mb_new_blocks 240 ext4_mb_free_blocks 208 ext4_mb_discard_group_preallocations 188 ext4_mb_seq_groups_show 164 ext4_mb_init_cache 152 ext4_mb_release_inode_pa 136 ext4_mb_seq_history_show ... to 220 ext4_mb_free_blocks 188 ext4_mb_seq_groups_show 176 ext4_mb_regular_allocator 164 ext4_mb_init_cache 156 ext4_mb_new_blocks 152 ext4_mb_release_inode_pa 136 ext4_mb_seq_history_show 124 ext4_mb_release_group_pa ... which still has some big functions in there, but not 432 bytes!
