KVM sometimes flushes host TLB entries, reading each one to check if it
corresponds to a guest KSeg0 address. In the absence of EntryHi.EHInv
bits to invalidate the whole entry, the entries will be set to unique
virtual addresses in KSeg0 (which is not TLB mapped), spaced 2*PAGE_SIZE
apart.
The TLB read however will clobber the CP0_PageMask register with
whatever page size that TLB entry had, and that same page size will be
written back into the TLB entry along with the unique address.
This would cause breakage when transparent huge pages are enabled on
64-bit host kernels, since huge page entries will overlap other nearby
entries when separated by only 2*PAGE_SIZE, causing a machine check
exception.
Fix this by restoring the old CP0_PageMask value (which should be set to
the normal page size) after reading the TLB entry if we're going to go
ahead and invalidate it.

kvm_mips_trans_replace() passes a pointer to KVM_GUEST_KSEGX(). This
breaks on 64-bit builds due to the cast of that 64-bit pointer to a
different sized 32-bit int. Cast the pointer argument to an unsigned

Update the KVM entry point to write CP0_EBase as a 64-bit register when
it is 64-bits wide, and to set the WG (write gate) bit if it exists in
order to write bits 63:30 (or 31:30 on MIPS32).
Prior to MIPS64r6 it was UNDEFINED to perform a 64-bit read or write of
a 32-bit COP0 register. Since this is dynamically generated code,
generate the right type of access depending on whether the kernel is
64-bit and cpu_has_ebase_wg.

Update the KVM entry code to set the CP0_Entry.KX bit on 64-bit kernels.
This is important to allow the entry code, running in kernel mode, to
access the full 64-bit address space right up to the point of entering
the guest, and immediately after exiting the guest, so it can safely
restore & save the guest context from 64-bit segments.

The MIPS KVM entry code (originally kvm_locore.S, later locore.S, and
now entry.c) has never quite been right when built for 64-bit, using
32-bit instructions when 64-bit instructions were needed for handling
64-bit registers and pointers. Fix several cases of this now.
The changes roughly fall into the following categories.
- COP0 scratch registers contain guest register values and the VCPU
pointer, and are themselves full width. Similarly CP0_EPC and
CP0_BadVAddr registers are full width (even though technically we
don't support 64-bit guest address spaces with trap & emulate KVM).
Use MFC0/MTC0 for accessing them.
- Handling of stack pointers and the VCPU pointer must match the pointer
size of the kernel ABI (always o32 or n64), so use ADDIU.
- The CPU number in thread_info, and the guest_{user,kernel}_asid arrays
in kvm_vcpu_arch are all 32 bit integers, so use lw (instead of LW) to
load them.

There are several unportable uses of CKSEG0ADDR() in MIPS KVM, which
implicitly assume that a host physical address will be in the low 512MB
of the physical address space (accessible in KSeg0). These assumptions
don't hold for highmem or on 64-bit kernels.
When interpreting the guest physical address when reading or overwriting
a trapping instruction, use kmap_atomic() to get a usable virtual
address to access guest memory, which is portable to 64-bit and highmem
kernels.

Calculate the PFN of the commpage using virt_to_phys() instead of
CPHYSADDR(). This is more portable as kzalloc() may allocate from XKPhys
instead of KSeg0 on 64-bit kernels, which CPHYSADDR() doesn't handle.
This is sufficient for highmem kernels too since kzalloc() will allocate
from lowmem in KSeg0.

The KSEGX() macro is defined to 32-bit sign extend the address argument
and logically AND the result with 0xe0000000, with the final result
usually compared against one of the CKSEG macros. However the literal
0xe0000000 is unsigned as the high bit is set, and is therefore
zero-extended on 64-bit kernels, resulting in the sign extension bits of
the argument being masked to zero. This results in the odd situation
where:
KSEGX(CKSEG) != CKSEG
(0xffffffff80000000 & 0x00000000e0000000) != 0xffffffff80000000)
Fix this by 32-bit sign extending the 0xe0000000 literal using
_ACAST32_.
This will help some MIPS KVM code handling 32-bit guest addresses to
work on 64-bit host kernels, but will also affect KSEGX in
dec_kn01_be_backend() on a 64-bit DECstation kernel, and the SiByte DMA
page ops KSEGX check in clear_page() and copy_page() on 64-bit SB1
kernels, neither of which appear to be designed with 64-bit segments in
mind anyway.

Kexec needs to know the addresses of all VMCSs that are active on
each CPU, so that it can flush them from the VMCS caches. It is
safe to record superfluous addresses that are not associated with
an active VMCS, but it is not safe to omit an address associated
with an active VMCS.
After a call to vmcs_load, the VMCS that was loaded is active on
the CPU. The VMCS should be added to the CPU's list of active
VMCSs before it is loaded.

KVM maintains L1's current VMCS in guest memory, at the guest physical
page identified by the argument to VMPTRLD. This makes hairy
time-of-check to time-of-use bugs possible,as VCPUs can be writing
the the VMCS page in memory while KVM is emulating VMLAUNCH and
VMRESUME.
The spec documents that writing to the VMCS page while it is loaded is
"undefined". Therefore it is reasonable to load the entire VMCS into
an internal cache during VMPTRLD and ignore writes to the VMCS page
-- the guest should be using VMREAD and VMWRITE to access the current
VMCS.
To adhere to the spec, KVM should flush the current VMCS during VMPTRLD,
and the target VMCS during VMCLEAR (as given by the operand to VMCLEAR).
Since this implementation of VMCS caching only maintains the the current
VMCS, VMCLEAR will only do a flush if the operand to VMCLEAR is the
current VMCS pointer.
KVM will also flush during VMXOFF, which is not mandated by the spec,
but also not in conflict with the spec.

When there is no AC power, NIC may not work after changing mac address.
Please refer to following link.
http://www.spinics.net/lists/netdev/msg356572.html
This issue is caused by runtime power management. When there is no AC
power, if we put NIC down (ifconfig down), the driver will be in runtime
suspend state and hardware will be put into D3 state. During this time,
driver cannot access hardware regisers. So if you set new mac address
during this time, it will not be set to hardware. After resume, NIC will
keep using the old mac address and the network will not work normally.
In this patch I add detecting runtime pm status when setting mac address.
If driver is in runtime suspend state, it will skip setting mac address, keep
the new mac address, and set the new mac address during runtime resume.

Not to call rtl8169_update_counters() to dump tally counter when driver

NIC will be put into D3 state during runtime suspend state. When set or
get hardware wol setting, driver will write or read hardware registers.
If we set or get hardware wol setting in runtime suspend state, because
NIC will in D3 state, the hardware registers read by driver will return all
0xff. That will let driver thinking register flag is not toggled and
then prints the warning message "rtl_counters_cond == 1 (loop: 1000,
delay: 10)" to kernel log.
For fixing this issue, add checking driver's pm runtime status in
rtl8169_get_wol() and rtl8169_set_wol().

Using set_bit() to set a bit in an integer is not a good idea, since
the function expects an unsigned long as argument, which can be 64 bit
wide. Coverity reports this problem as
>>> CID 1364488: Memory - illegal accesses (INCOMPATIBLE_CAST)
>>> Pointer "&ret" points to an object whose effective type is "int"
>>> (32 bits, signed) but is dereferenced as a wider "unsigned
+long" (64 bits, unsigned). This may lead to memory corruption.
245 set_bit(1, (unsigned long *)&ret);
Just use BIT instead.

AT_BASE_PLATFORM which s390 doesn't use, but lets define it now and add
