Commits bcf8c7e7703bb2bbde66bec26a81fed4be9cd1d4 and
4bf7753b8ab7c704ca864b1653367ea9cfe68a25 introduced compilation errors
("error: 'NR_IRQS_LEGACY' undeclared (first use in this function)") because
they remove the asm/irq.h inclusion while the init_time function needs it
for the NR_IRQS_LEGACY definition.
In the other hand, the point of these commits is to remove board file
support, and init_time is only needed when booting non-DT boards, we can
thus safely remove init_time functions.

Merge "at91: cleanup for 3.19 #1" from Nicolas Ferre:
"The pull-request that was sent late for 3.18. It was removing the old
!MMU at91x40 and 2 board files plus the whole code in at91sam9g45 &

particular ones, the EK were the only one to use this code. We can use
these boards with DT right now."
First batch of cleanup/SoC for 3.19:
- removal of old at91x40 !MMU ARM7TDMI support which was kind of rusty
- removal of board-sam9m10g45ek.c and board-sam9rlek.c from mach-at91
and the code related to these board C files + defconfigs. Use DT for them
now!

Pull "dts, kbuild: Implement support for dtb vendor subdirs" from
Robert Richter:
dts, kbuild: Implement support for dtb vendor subdirs
For arm64 we want to put dts files into vendor's subdirectories from
the beginning. This patch set implements this. As this is a generic
kbuild implementation, vendor subdirs will be also available for
arch/arm and other architectures. The subdirectory tree is also
reflected in the install path.
A new makefile variable dts-dirs is introduced to point to dts
subdirs. This variable is used by kbuild for building and installation
of dtb files.
A dts Makefile looks now as follows:
----
dtb-$(CONFIG_...) += some_file_1.dtb
dtb-$(CONFIG_...) += some_file_2.dtb
dts-dirs += dir_vendor_a
dts-dirs += dir_vendor_b
always := $(dtb-y)
subdir-y := $(dts-dirs)
clean-files := *.dtb
----
This patches also introduces the dtbs_install make target for
arm64. Install rules are moved to Makefile.dtbinst using the same
style and calling convention like for modinst and fwinst.

As there is currently no-one to take care of this old !MMU target and as its
support in recent kernels is a bit rotten, remove this at91x40 support and the
board file associated with it (at91eb01).
There are modern ARM !MMU in Mainline now so this target is not interesting for
building tests anymore. It would be better to start from these modern ARM !MMU
platforms to reintroduce at91x40 support if needed.

In order to access the shadow VMCS, we need to load it. At this point,
vmx->loaded_vmcs->vmcs and the actually loaded one start to differ. If
we now get preempted by Linux, vmx_vcpu_put and, on return, the
vmx_vcpu_load will work against the wrong vmcs. That can cause
copy_shadow_to_vmcs12 to corrupt the vmcs12 state.
Fix the issue by disabling preemption during the copy operation.
copy_vmcs12_to_shadow is safe from this issue as it is executed by
vmx_vcpu_run when preemption is already disabled before vmentry.
This bug is exposed by running Jailhouse within KVM on CPUs with
shadow VMCS support. Jailhouse never expects an interrupt pending
vmexit, but the bug can cause it if, after copy_shadow_to_vmcs12
is preempted, the active VMCS happens to have the virtual interrupt
pending flag set in the CPU-based execution controls.

Commit d1442d85cc30 ("KVM: x86: Handle errors when RIP is set during far
jumps") introduced a bug that caused the fix to be incomplete. Due to
incorrect evaluation, far jump to segment with L bit cleared (i.e., 32-bit
segment) and RIP with any of the high bits set (i.e, RIP[63:32] != 0) set may
not trigger #GP. As we know, this imposes a security problem.
In addition, the condition for two warnings was incorrect.

Rusty noticed a Really Bad Bug (tm) in my NT fix. The entry code
reads out of bounds, causing the NT fix to be unreliable. But, and
this is much, much worse, if your stack is somehow just below the
top of the direct map (or a hole), you read out of bounds and crash.
Excerpt from the crash:
[ 1.129513] RSP: 0018:ffff88001da4bf88 EFLAGS: 00010296
2b:* f7 84 24 90 00 00 00 testl $0x4000,0x90(%rsp)
That read is deterministically above the top of the stack. I
thought I even single-stepped through this code when I wrote it to
check the offset, but I clearly screwed it up.

With legacy booting, the platform init code was taking care of
the configuring of GPIOs. With device tree based booting, things
may or may not work depending what bootloader has configured or
if the legacy platform code gets called.
Let's add support for the pwrdn and reset GPIOs to the smc91x
driver to fix the issues of smc91x not working properly when
booted in device tree mode.
And let's change n900 to use these settings as some versions
of the bootloader do not configure things properly causing
errors.

Since CONFIG_HIGHMEM got enabled on ARMv5 Kirkwood, we have noticed a
very significant drop in networking performance. The test were
conducted on an OpenBlocks A7 board. Without this patch, the outgoing
performance measured with iperf are:
- highmem OFF, TSO OFF 544 Mbit/s
- highmem OFF, TSO ON 942 Mbit/s
- highmem ON, TSO OFF 306 Mbit/s
- highmem ON, TSO ON 246 Mbit/s
On this Kirkwood platform, the L2 cache is a Feroceon cache, and with
this cache, all the range operations have to be done on virtual
addresses and not physical addresses. Therefore, whenever
CONFIG_HIGHMEM is enabled, the cache maintenance operations call
kmap_atomic_pfn() and kunmap_atomic().
However, kmap_atomic_pfn() does not implement the same fast path for
non-highmem pages as the one implemented in kmap_atomic(), and this is
one of the reason for the performance drop. While this patch does not
fully restore the performances, it clearly improves them a lot:
without patch with patch
- highmem ON, TSO OFF 306 Mbit/s 387 Mbit/s
- highmem ON, TSO ON 246 Mbit/s 434 Mbit/s
We're still far from the !CONFIG_HIGHMEM performances, but it does
improve a bit the situation.
Thanks a lot to Ezequiel Garcia and Gregory Clement for all the
testing work around this topic.

Russell King suggested [1]:
"I'd ask for one change. Please make all these messages start with
"L2C-310 OF" not "PL310 OF:". The device is described in ARM
documentation as a L2C-310 not PL310. (Also note the : is dropped
too - most of the other messages don't have the : either.)
The:
"PL310 OF: cache setting yield illegal associativity
PL310 OF: -1073346556 calculated, only 8 and 16 legal"
message could also be changed to something like:
"L2C-310 OF cache associativity %d invalid, only 8 or 16 permittedn"

Emulation of code that is 14 bytes to the segment limit or closer
(e.g. RIP = 0xFFFFFFF2 after reset) is broken because we try to read as
many as 15 bytes from the beginning of the instruction, and __linearize
fails when the passed (address, size) pair reaches out of the segment.
To fix this, let __linearize return the maximum accessible size (clamped
to 2^32-1) for usage in __do_insn_fetch_bytes, and avoid the limit check
by passing zero for the desired size.
For expand-down segments, __linearize is performing a redundant check.
(u32)(addr.ea + size - 1) <= lim can only happen if addr.ea is close
to 4GB; in this case, addr.ea + size - 1 will also fail the check against
the upper bound of the segment (which is provided by the D/B bit).
After eliminating the redundant check, it is simple to compute
the *max_size for expand-down segments too.
Now that the limit check is done in __do_insn_fetch_bytes, we want
to inject a general protection fault there if size < op_size (like
__linearize would have done), instead of just aborting.
This fixes booting Tiano Core from emulated flash with EPT disabled.

The error code for #GP and #SS is zero when the segment is used to
access an operand or an instruction. It is only non-zero when
a segment register is being loaded; for limit checks this means
cases such as:
* for #GP, when RIP is beyond the limit on a far call (before the first
instruction is executed). We do not implement this check, but it
would be in em_jmp_far/em_call_far.
* for #SS, if the new stack overflows during an inter-privilege-level
call to a non-conforming code segment. We do not implement stack
switching at all.
So use an error code of zero.
