To avoid branch merge conflict issue, it is using this load map, and this patch is 3) part. 1) add new style clock in platform 2) add new style clock method in driver 3) remove old tyle clock from platform Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Simon Horman <horms+renesas@verge.net.au>

There is one small piece of platform dependent code in the jz4740-i2s driver. It uses the DMA request type constants which are defined in a platform specific header. We can solve this by moving them from the platform specific header to the I2S driver.

Another key fix is a build fix which would produce output that simply would not decompress correctly in some configuration, due to the existing Makefiles picking up an unfortunate local label and mistaking it for the global symbol _end. Additional fixes include the handling of 64-bit numbers when setting the vdso data page (a latent bug which became manifest when i386 started exporting a vdso with time functions), a fix to the new MSR manipulation accessors which would cause features to not get properly unblocked, a build fix for 32-bit userland, and a few new platform quirks" * 'x86-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86, vdso, time: Cast tv_nsec to u64 for proper shifting in update_vsyscall() x86: Fix typo in MSR_IA32_MISC_ENABLE_LIMIT_CPUID macro x86: Fix typo preventing msr_set/clear_bit from having an effect x86/intel: Add quirk to disable HPET for the Baytrail platform x86/hpet: Make boot_hpet_disable extern x86-64, build: Fix stack protector Makefile breakage with 32-bit userland x86/reboot: Add reboot quirk for Certec BPC600 asmlinkage: Add explicit __visible to drivers/*, lib/*, kernel/* asmlinkage, x86: Add explicit __visible to arch/x86/* asmlinkage: Revert "lto: Make asmlinkage __visible" x86, build: Don't get confused by local symbols x86/efi: earlyprintk=efi,keep fix

Such as early_efi_write is marked as __init, also it will use early_ioremap which is init function as well. To fix this issue, I added early initcall early_efi_map_fb which maps the whole efi fb for later use. OTOH, adding a wrapper function early_efi_map which calls early_ioremap before ioremap is available.

For pgd_ERROR() and pmd_ERROR(), output something similar to x86, giving the address of the pgd/pmd as well as it's value. Also provide the caller, since these macros are invoked from pgd_clear_bad() and pmd_clear_bad() which provides little context as to what high level operation was occuring when the BAD state was detected.

PMD and PTE tables are of size PAGE_SIZE, so none of the sub-PAGE_SIZE bits should be set. We also complement this with a check that the physical address the pud/pmd points to is valid memory. PowerPC was used as a guide while implementating this. Signed-off-by: David S. Miller <davem@davemloft.net>

Calls to gup_huge_pmd() are guarded with a check of pmd_large(), so we just need to add a valid bit check. Signed-off-by: David S. Miller <davem@davemloft.net>

However we weren't handling this properly in the huge PMD paths. First of all, the page table walker in the TSB miss path only checks for _PAGE_PMD_HUGE. So the generic pmdp_invalidate() would clear _PAGE_PRESENT but the TLB miss paths would still load it into the TLB as a valid huge PMD. Fix this by clearing the valid bit in pmdp_invalidate(), and also checking the valid bit in USER_PGTABLE_CHECK_PMD_HUGE using "brgez" since _PAGE_VALID is bit 63 in both the sun4u and sun4v pte layouts.
