Wait for OMAP3430 clocks to enable before returning from clk_enable()

GPTIMER modules can take 200 to 300 microseconds to become available after

won't wait for them before returning from clk_enable(). If the system
attempts to access a GPTIMER register too quickly after the clk_enable(),
the system will halt with something similar to the following in the

fix hugepages leak due to pagetable page sharing
The shared page table code for hugetlb memory on x86 and x86_64
is causing a leak. When a user of hugepages exits using this code
the system leaks some of the hugepages.
-------------------------------------------------------
Part of /proc/meminfo just before database startup:
HugePages_Total: 5500
HugePages_Free: 5500
HugePages_Rsvd: 0
Hugepagesize: 2048 kB
Just before shutdown:
HugePages_Total: 5500
HugePages_Free: 4475
HugePages_Rsvd: 0
Hugepagesize: 2048 kB
The problem occurs durring a fork, in copy_hugetlb_page_range(). It
locates the dst_pte using huge_pte_alloc(). Since huge_pte_alloc() calls
huge_pmd_share() it will share the pmd page if can, yet the main loop in
copy_hugetlb_page_range() does a get_page() on every hugepage. This is a
violation of the shared hugepmd pagetable protocol and creates additional
referenced to the hugepages causing a leak when the unmap of the VMA
occurs. We can skip the entire replication of the ptes when the hugepage
pagetables are shared. The attached patch skips copying the ptes and the
get_page() calls if the hugetlbpage pagetable is shared.
