Earlier patches select HAVE_SCHED_CLOCK for omaps. To have working sched_clock also for MPU timer, we need to implement it in a way where the right one gets selected during the runtime. Signed-off-by: NTony Lindgren <tony@atomide.com>

For omap15xx and 730 we need to use the MPU timer as the 32K timer is not available. For omap16xx we want to use the 32K timer because of PM. Fix this by allowing to build in both timers. Signed-off-by: NTony Lindgren <tony@atomide.com>

Commit 56a6a19d ("omap2plus: prm: Trvial build break fix for undefined reference to 'omap2_prm_read_mod_reg'") generates a lot of warnings on boot since clockdomain functions that manipulate wake-up dependencies are not implemented yet on OMAP4 for 2.6.38. This patch bypasses the OMAP2/3 functions on OMAP4, which in turn avoids the warnings when the functions would attempt to call the underlying OMAP2/3 PRCM functions. A one-line warning is still logged from the clockdomain code that the OMAP4 wake-up dependency code is not yet implemented. A clockdomain wake-up and sleep dependency implementation for OMAP4 from Rajendra should be possible to merge during the 2.6.39 merge window: http://www.mail-archive.com/linux-omap@vger.kernel.org/msg41748.html http://www.mail-archive.com/linux-omap@vger.kernel.org/msg42222.htmlReported-by: NRussell King <rmk+kernel@arm.linux.org.uk> Cc: Rajendra Nayak <rnayak@ti.com> Cc: Benoît Cousson <b-cousson@ti.com> Cc: Santosh Shilimkar <santosh.shilimkar@ti.com> Acked-by: NSantosh Shilimkar <santosh.shilimkar@ti.com> Signed-off-by: NPaul Walmsley <paul@pwsan.com>

When DEBUG_LL is not set, we don't want __error_a re-entering __lookup_machine_type - we want it to go to the error function. This used to be the case before we reorganized the layout for hotplug cpu, as we used to fall through to __error. With the changed layout, we need an explicit branch here instead.

Do not use memory bank info to request the "system ram" resources as they do not track holes created by memblock_remove inside machine's reserve callback. If the removed memory is passed as platform_device's ioresource, then drivers that call request_mem_region would fail due to a conflict with the incorrectly configured system ram resource. Instead, iterate through the regions of memblock.memory and add those as "System RAM" resources.

pte alloc routines must wait for split_huge_page if the pmd is not present and not null (i.e. pmd_trans_splitting). The additional branches are optimized away at compile time by pmd_trans_splitting if the config option is off. However we must pass the vma down in order to know the anon_vma lock to wait for.

Four architectures (arm, mips, sparc, x86) use __vmalloc_area() for module_init(). Much of the code is duplicated and can be generalized in a globally accessible function, __vmalloc_node_range(). __vmalloc_node() now calls into __vmalloc_node_range() with a range of [VMALLOC_START, VMALLOC_END) for functionally equivalent behavior. Each architecture may then use __vmalloc_node_range() directly to remove the duplication of code.
