Guests worked normally in shadow paging mode (ept=0) on my test machine.
Please check if the first two patches reflect what you meant correctly.
Takuya Yoshikawa (3):
[1] KVM: x86: MMU: Move parent_pte handling from kvm_mmu_get_page() to
link_shadow_page()
[2] KVM: x86: MMU: Use for_each_rma
Every time kvm_mmu_get_page() is called with a non-NULL parent_pte
argument, link_shadow_page() follows that to set the parent entry so
that the new mapping will point to the returned page table.
Moving parent_pte handling there allows to clean up the code because
parent_pte is passed to kvm_mmu_g

As kvm_mmu_get_page() was changed so that every parent pointer would not
get into the sp->parent_ptes chain before the entry pointed to by it was
set properly, we can use the for_each_rmap_spte macro instead of
pte_list_walk().

As of 3c3b177a9369 ("reservation: add suppport for read-only access
using rcu") linux/reservation.h uses lockdep macros:
+#define reservation_object_held(obj) lockdep_is_held(&(obj)->lock.base)
This results in build errors when lockdep is disabled as lockdep_is_held()
is only available when lockd

This patch adds the bus noes using VDD_INT for Exynos4x12 SoC.
Exynos4x12 has the following AXI buses to translate data between
DRAM and sub-blocks.
Following list specifies the detailed relation between DRAM and sub-blocks:
- ACLK100 clock for PERIL/PERIR/MFC(PCLK)
- ACLK160 clock for CAM/TV/LCD
This patch-set includes the two features as following. The generic exynos bus
frequency driver is able to support almost Exynos SoCs for bus frequency
scaling. And the new passive governor is able to make the dependency on
between devices for frequency/voltage scaling. I had posted the patch-set[1]
This patch modifies the following sysfs entry of DEVFREQ framework
because the devfreq device using passive governor don't need the same
information of the devfreq device using rest governor.
- polling_interval: passive gov don't use the sampling rate.
- available_governors : passive gov don't
This patch adds the bus noes using VDD_MIF for Exynos4x12 SoC.

THis patch adds the bus device tree nodes for both MIF (Memory) and INT
(Internal) block to enable the bus frequency.
The DMC bus is parent device in MIF block using VDD_MIF and the LEFTBUS
bus is parent device in INT block using VDD_INT.
