All architecturally defined bits in the FPU implementation register
are read only & unchanging. It contains some implementation-defined
bits but the architecture manual states "This bits are explicitly not
intended to be used for mode control functions" which seems to provide
justification for viewing the register as a whole as unchanging. This
being the case we can simply re-use the value we read at boot rather
than having to re-read it later, and avoid the complexity which that
read entails.

The sead3-mtd.o is built for obj-y -- and hence this code is always
present. It will never be modular, so using module_init as an alias
for __initcall can be somewhat misleading.
Fix this up now, so that we can relocate module_init from
init.h into module.h in the future. If we don't do this, we'd
have to add module.h to obviously non-modular code, and that
would be a worse thing.
Note that direct use of __initcall is discouraged, vs. one
of the priority categorized subgroups. As __initcall gets
mapped onto device_initcall, our use of device_initcall
directly in this change means that the runtime impact is
zero -- it will remain at level 6 in initcall ordering.
We also fix a missing semicolon, which this change uncovers.

Loongson-1 is a 32-bit MIPS CPU and Loongson-2/3 are 64-bit MIPS CPUs,
and both Loongson-2/3 has the same PRID IMP filed (0x6300). As a
result, renaming PRID_IMP_LOONGSON1 and PRID_IMP_LOONGSON2 to
PRID_IMP_LOONGSON_32 and PRID_IMP_LOONGSON_64 will make more sense.

The original MIPS hibernate code flushes cache and TLB entries in
swsusp_arch_resume(). But they are removed in Commit 44eeab67416711
(MIPS: Hibernation: Remove SMP TLB and cacheflushing code.). A cross-
CPU flush is surely unnecessary because all but the local CPU have
already been disabled. But a local flush (at least the TLB flush) is
needed. When we do hibernation on Loongson-3 with an E1000E NIC, it is
very easy to produce a kernel panic (kernel page fault, or unaligned
access). The root cause is E1000E driver use vzalloc_node() to allocate
pages, the stale TLB entries of the booting kernel will be misused by
the resumed target kernel.

The UART register names are identical to the ones in uapi/linux/serial_reg.h,

This patch adds a jited flag into sk_filter struct in order to indicate
whether a filter is currently jited or not. The size of sk_filter is
not being expanded as the 32 bit 'len' member allows upper bits to be
reused since a filter can currently only grow as large as BPF_MAXINSNS.
Therefore, there's enough room also for other in future needed flags to
reuse 'len' field if necessary. The jited flag also allows for having
alternative interpreter functions running as currently, we can only
detect jit compiled filters by testing fp->bpf_func to not equal the
address of sk_run_filter().

Currently we save the host PMU configuration, counter values, etc.,
when entering a guest, and restore it on return from the guest.
(We have to do this because the guest has control of the PMU while
it is executing.) However, we missed saving/restoring the SIAR and
SDAR registers, as well as the registers which are new on POWER8,
namely SIER and MMCR2.
This adds code to save the values of these registers when entering
the guest and restore them on exit. This also works around the bug
in POWER8 where setting PMAE with a counter already negative doesn't
generate an interrupt.

Commit c7699822bc21 ("KVM: PPC: Book3S HV: Make physical thread 0 do
the MMU switching") reordered the guest entry/exit code so that most
of the guest register save/restore code happened in guest MMU context.
A side effect of that is that the timebase still contains the guest
timebase value at the point where we compute and use vcpu->arch.dec_expires,
and therefore that is now a guest timebase value rather than a host
timebase value. That in turn means that the timeouts computed in
kvmppc_set_timer() are wrong if the timebase offset for the guest is
non-zero. The consequence of that is things such as "sleep 1" in a
guest after migration may sleep for much longer than they should.
This fixes the problem by converting between guest and host timebase
values as necessary, by adding or subtracting the timebase offset.
This also fixes an incorrect comment.

With HV KVM, some high-frequency hypercalls such as H_ENTER are handled
in real mode, and need to access the memslots array for the guest.
Accessing the memslots array is safe, because we hold the SRCU read
lock for the whole time that a guest vcpu is running. However, the
checks that kvm_memslots() does when lockdep is enabled are potentially
unsafe in real mode, when only the linear mapping is available.
Furthermore, kvm_memslots() can be called from a secondary CPU thread,
which is an offline CPU from the point of view of the host kernel,
and is not running the task which holds the SRCU read lock.
To avoid false positives in the checks in kvm_memslots(), and to avoid
possible side effects from doing the checks in real mode, this replaces
kvm_memslots() with kvm_memslots_raw() in all the places that execute
in real mode. kvm_memslots_raw() is a new function that is like
kvm_memslots() but uses rcu_dereference_raw_notrace() instead of
kvm_dereference_check().

The in-kernel emulation of RTAS functions needs to read the argument
buffer from guest memory in order to find out what function is being
requested. The guest supplies the guest physical address of the buffer,
and on a real system the code that reads that buffer would run in guest
real mode. In guest real mode, the processor ignores the top 4 bits
of the address specified in load and store instructions. In order to
emulate that behaviour correctly, we need to mask off those bits
before calling kvm_read_guest() or kvm_write_guest(). This adds that
masking.

It also adds emulation of the TM state changes when delivering IRQs

transactional when an IRQ occurs, the TM state is changed to
suspended, otherwise it's left unchanged.

On x86 uniprocessor systems topology_physical_package_id() returns -1

The previous NR_CPUS=2 default is not an optimal default for current
Malta setups where it is common to have more than 2 CPUs available. It
makes sense to increase this to a number which covers all common setups
currently in use, such that all of those cores are usable. 8 seems to
fit that description.
If the user has less than 8 CPUs & they wish to have a more optimal

The au1xxx-ide driver isn't any faster than pata_platform since it
spends a lot of time busy waiting for DMA to finish; faster PIO/DMA
modes only work on the db1200 with a certain cpu speed, UDMA is broken,
and finally the old IDE layer is on death row, so time to switch to
the newer ATA layer.
