We need to ensure the enabled=0 write happens before we
start disabling the actual counters, so that a pcm_amd_enable()
will not enable one underneath us.
I think the race is impossible anyway, we always balance the
ops within any one context and perform enable() with IRQs disabled.

PCI still doesn't work on sh7785lcr 29bit 256M map mode.
On SH7785, PCI -> SHwy address translation is not base+offset but
somewhat like base|offset (See HW Manual (rej09b0261) Fig. 13.11).
So, you can't export CS2,3,4,5 by 256M at CS2 (results CS0,1,2,3
exported, I guess). There are two candidates.
a) 128M@CS2 + 128M@CS4
b) 512M@CS0
Attached patch is B. It maps 512M Byte at 0 independently of memory
size. It results CS0 to CS6 and perhaps some more being accessible
from PCI.
Tested on
7785lcr 29bit 128M map
7785lcr 29bit 256M map
(NOT tested on 32bit)

There were a number of issues with the DSP context save/restore code,
mostly left-over relics from when it was introduced on SH3-DSP with
little follow-up testing, resulting in things like task_pt_dspregs()
referencing incorrect state on the stack.
This follows the MIPS convention of tracking the DSP state in the
thread_struct and handling the state save/restore in switch_to() and
finish_arch_switch() respectively. The regset interface is also updated,
which allows us to finally be rid of task_pt_dspregs() and the special
cased task_pt_regs().

All logical processors with APIC ID values of 255 and greater will have their
APIC reported through Processor X2APIC structure (type-9 entry type) and all
logical processors with APIC ID less than 255 will have their APIC reported
through legacy Processor Local APIC (type-0 entry type) only. This is the
same case even for NMI structure reporting.
The Processor X2APIC Affinity structure provides the association between the
X2APIC ID of a logical processor and the proximity domain to which the logical
processor belongs.
For OSPM, Procssor IDs outside the 0-254 range are to be declared as Device()
objects in the ACPI namespace.

pci mmap code was doing memtype reserve for a while now. Recently we
added memtype tracking in remap_pfn_range, and pci code indirectly calls
remap_pfn_range. So, we don't need seperate tracking in pci code
anymore. Which means a patch that removes ~50 lines of code :-).
Also, recently we found out that the pci tracking is not working as we expect
it to work in some cases. Specifically, userlevel X mmap of pci, with some
recent version of X, is having a problem with vm_page_prot getting reset.
The pci tracking uses vm_page_prot to pass on the protection type from parent
to child during fork.
a) Parent does a pci mmap
b) We look at PAT and get either UC_MINUS or WC mapping for parent
c) Store that mapping type in vma vm_page_prot for future use
d) This thread does a fork
e) Fork results in mmap_ops ->open for the child process
f) We get the vm_page_prot from vma and reserve that type for the child process
But, between c) and e) above, the vma vm_page_prot is getting reset to zero.
This results in PAT reserve failing at the time of fork as in here.
http://marc.info/?l=linux-kernel&m=123858163103240&w=2
This cleanup makes the above problem go away as we do not depend on
vm_page_prot in our PAT code anymore.

The __restore_processor_state() fn restores %gs on resume from S3. As
such, it cannot be protected by the stack-protector guard since %gs will
not be correct on function entry.
There are only a few other fns in this file and it should not negatively
impact kernel security that they will also have the stack-protector
guard removed (and so it's not worth moving them to another file).
Without this change, S3 resume on a kernel built with
CONFIG_CC_STACKPROTECTOR_ALL=y will fail.

Impact: code size reduction (possibly critical)
The x86 boot and decompression code has no use of the branch profiling
constructs, so disable them. This would bloat the setup code by as
much as 14K, eating up a fairly large chunk of the 32K area we are
guaranteed to have.

Impact: unification of pci-dma macros and pci_32.h removal
This patch unifies the definition of the pci_unmap_addr*, pci_unmap_len*
and DECLARE_PCI_UNMAP* macros. This makes sense because the pci_unmap
functions are no longer no-ops anymore when the kernel runs with
CONFIG_DMA_API_DEBUG. Without an iommu or DMA_API_DEBUG it is a no-op on 32 bit
because the dma mapping path returns a physical address and therefore the
dma-api implementation has no internal state which needs to be destroyed with
an unmap call.
This unification also simplifies the port of x86_64 iommu drivers to 32 bit x86
and let us get rid of pci_32.h.

We only add the platform or variant directory to core-y if it
contains a Makefile. Consequently, we can remove the Makefiles
for the dc232b and fsf processor variants.

platform_get/set_rtc_time() is not implemented by any of the supported
xtensa platforms. Remove the facility completely.
The initial seconds for xtime come from read_persistent_clock() which
returns just 0 in the generic implementation. Platforms that sport a
persistent clock can implement this function.
This is needed to implement the ccount as a clock source.

Current xtensa implementation of sched_clock() is the same as the
generic one. Just remove it, the weak symbol in kernel/sched_clock.c
will be used instead.

The linker script should not assume a fix offset in memory for the
kernel, this is platform-specific, so let the platform set it.
