2007-05-21Detach sched.h from mm.hAlexey Dobriyan1-1/+2
First thing mm.h does is including sched.h solely for can_do_mlock() inline function which has "current" dereference inside. By dealing with can_do_mlock() mm.h can be detached from sched.h which is good. See below, why. This patch a) removes unconditional inclusion of sched.h from mm.h b) makes can_do_mlock() normal function in mm/mlock.c c) exports can_do_mlock() to not break compilation d) adds sched.h inclusions back to files that were getting it indirectly. e) adds less bloated headers to some files (asm/signal.h, jiffies.h) that were getting them indirectly Net result is: a) mm.h users would get less code to open, read, preprocess, parse, ... if they don't need sched.h b) sched.h stops being dependency for significant number of files: on x86_64 allmodconfig touching sched.h results in recompile of 4083 files, after patch it's only 3744 (-8.3%).

2007-05-05[ARM] mm 10: allow memory type to be specified with ioremapRussell King2-9/+9
__ioremap() took a set of page table flags (specifically the cacheable and bufferable bits) to control the mapping type. However, with the advent of ARMv6, this is far too limited. Replace the page table flags with a memory type index, so that the desired attributes can be selected from the mem_type table. Finally, to prevent silent miscompilation due to the differing arguments, rename the __ioremap() and __ioremap_pfn() functions. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

The iop348 processor integrates an Xscale (XSC3 512KB L2 Cache) core with a Serial Attached SCSI (SAS) controller, multi-ported DDR2 memory controller, 3 Application Direct Memory Access (DMA) controllers, a 133Mhz PCI-X interface, a x8 PCI-Express interface, and other peripherals to form a system-on-a-chip RAID subsystem engine. The iop342 processor replaces the SAS controller with a second Xscale core for dual core embedded applications. The iop341 processor is the single core version of iop342. This patch supports the two Intel customer reference platforms iq81340mc for external storage and iq81340sc for direct attach (HBA) development.
