The PowerPC Book-E watchdog driver (booke_wdt.c) defines a default timeout
value in the code based on whether it's a Freescale Book-E part of not.
Instead of having hard-coded values in the driver, make it a Kconfig
option.
As newer chips gets faster, the current default values become less
appropriate, since the timeout sometimes occurs before the kernel finishes
booting. Making the value a Kconfig option allows BSPs to configure a new
value without requiring the wdt_period command-line parameter to be set.

On Freescale parts typically have TLB array for large mappings that we can
bolt the linear mapping into. We utilize the code that already exists
on PPC32 on the 64-bit side to setup the linear mapping to be cover by
bolted TLB entries. We utilize a quarter of the variable size TLB array
for this purpose.
Additionally, we limit the amount of memory to what we can cover via
bolted entries so we don't get secondary faults in the TLB miss
handlers. We should fix this limitation in the future.

Update setup_page_sizes() to support for a MMU v1.0 FSL style MMU
implementation. In such a processor, we don't have TLB0PS or EPTCFG
registers (and access to these registers may cause exceptions). We need
to parse the older format of TLBnCFG for page size support. Additionaly,
assume since we are an FSL implementation that we have 2 TLB arrays and
the second array contains the variable size pages.

* Supports only one contiguous SRAM window
* Drivers can do the following in Kconfig to use these APIs
"select FSL_85XX_CACHE_SRAM if MPC85xx"
* Required SRAM size and the offset where SRAM should be mapped must be
provided at kernel command line as :

On an arch 2.06 hypervisor, a pending perfmon interrupt will be delivered
to the hypervisor at any point the guest is running, regardless of
MSR[EE]. In order to reflect this interrupt, the hypervisor has to mask
the interrupt in PMGC0 -- and set MSRP[PMMP] to intercept futher guest
accesses to the PMRs to detect when to unmask (and prevent the guest from
unmasking early, or seeing inconsistent state).
This has the side effect of ignoring any changes the guest makes to
MSR[PMM], so wait until after the interrupt is clear, and thus the
hypervisor should have cleared MSRP[PMMP], before setting MSR[PMM]. The
counters wil not actually run until PMGC0[FAC] is cleared in
pmc_start_ctrs(), so this will not reduce the effectiveness of PMM.

There exists a four line chunk of code, which when configured for
64 bit address space, can incorrectly set certain page flags during
the TLB creation. It turns out that this is code which isn't used,
but might still serve a purpose. Since it isn't obvious why it exists
or why it causes problems, the below description covers both in detail.
For powerpc bootstrap, the physical memory (at most 768M), is mapped
into the kernel space via the following path:
MMU_init()
|
+ adjust_total_lowmem()
|
+ map_mem_in_cams()
|
+ settlbcam(i, virt, phys, cam_sz, PAGE_KERNEL_X, 0);
On settlbcam(), the kernel will create TLB entries according to the flag,
PAGE_KERNEL_X.
settlbcam()
{
...
TLBCAM[index].MAS1 = MAS1_VALID
| MAS1_IPROT | MAS1_TSIZE(tsize) | MAS1_TID(pid);
^
These entries cannot be invalidated by the
kernel since MAS1_IPROT is set on TLB property.
...
if (flags & _PAGE_USER) {
TLBCAM[index].MAS3 |= MAS3_UX | MAS3_UR;
TLBCAM[index].MAS3 |= ((flags & _PAGE_RW) ? MAS3_UW : 0);
}
For classic BookE (flags & _PAGE_USER) is 'zero' so it's fine.
But on boards like the the Freescale P4080, we want to support 36-bit
physical address on it. So the following options may be set:
CONFIG_FSL_BOOKE=y
CONFIG_PTE_64BIT=y
CONFIG_PHYS_64BIT=y
As a result, boards like the P4080 will introduce PTE format as Book3E.
As per the file: arch/powerpc/include/asm/pgtable-ppc32.h
* #elif defined(CONFIG_FSL_BOOKE) && defined(CONFIG_PTE_64BIT)
* #include <asm/pte-book3e.h>
So PAGE_KERNEL_X is __pgprot(_PAGE_BASE | _PAGE_KERNEL_RWX) and the
book3E version of _PAGE_KERNEL_RWX is defined with:
(_PAGE_BAP_SW | _PAGE_BAP_SR | _PAGE_DIRTY | _PAGE_BAP_SX)
Note the _PAGE_BAP_SR, which is also defined in the book3E _PAGE_USER:
#define _PAGE_USER (_PAGE_BAP_UR | _PAGE_BAP_SR) /* Can be read */
So the possibility exists to wrongly assign the user MAS3_U<RWX> bits
to kernel (PAGE_KERNEL_X) address space via the following code fragment:
if (flags & _PAGE_USER) {
TLBCAM[index].MAS3 |= MAS3_UX | MAS3_UR;
TLBCAM[index].MAS3 |= ((flags & _PAGE_RW) ? MAS3_UW : 0);
}
Here is a dump of the TLB info from Simics with the above code present:
------
L2 TLB1
GT SSS UUU V I
Row Logical Physical SS TLPID TID WIMGE XWR XWR F P V
----- ----------------- ------------------- -- ----- ----- ----- --- --- - - -
0 c0000000-cfffffff 000000000-00fffffff 00 0 0 M XWR XWR 0 1 1
1 d0000000-dfffffff 010000000-01fffffff 00 0 0 M XWR XWR 0 1 1
2 e0000000-efffffff 020000000-02fffffff 00 0 0 M XWR XWR 0 1 1
Actually this conditional code was used for two legacy functions:
1: support KGDB to set break point.
KGDB already dropped this; now uses its core write to set break point.
2: io_block_mapping() to create TLB in segmentation size (not PAGE_SIZE)
for device IO space.
This use case is also removed from the latest PowerPC kernel.
However, there may still be a use case for it in the future, like
large user pages, so we can't remove it entirely. As an alternative,
we match on all bits of _PAGE_USER instead of just any bits, so the
case where just _PAGE_BAP_SR is set can't sneak through.
With this done, the TLB appears without U having XWR as below:
-------
L2 TLB1
GT SSS UUU V I
Row Logical Physical SS TLPID TID WIMGE XWR XWR F P V
----- ----------------- ------------------- -- ----- ----- ----- --- --- - - -
0 c0000000-cfffffff 000000000-00fffffff 00 0 0 M XWR 0 1 1
1 d0000000-dfffffff 010000000-01fffffff 00 0 0 M XWR 0 1 1
2 e0000000-efffffff 020000000-02fffffff 00 0 0 M XWR 0 1 1

Xen requires that all pages containing pagetable entries to be mapped
read-only. If pages used for the initial pagetable are already mapped
then we can change the mapping to RO. However, if they are initially
unmapped, we need to make sure that when they are later mapped, they
are also mapped RO.
We do this by knowing that the kernel pagetable memory is pre-allocated
in the range e820_table_start - e820_table_end, so any pfn within this
range should be mapped read-only. However, the pagetable setup code
early_ioremaps the pages to write their entries, so we must make sure
that mappings created in the early_ioremap fixmap area are mapped RW.
(Those mappings are removed before the pages are presented to Xen
as pagetable pages.)

Commit 0793448 "DMAENGINE: generic channel status v2" changed the interface for
how dma channel progress is retrieved. It inadvertently exported an internal
helper function ioat_tx_status() instead of ioat_dma_tx_status(). The latter
polls the hardware to get the latest completion state, while the helper just
evaluates the current state without touching hardware. The effect is that we
end up waiting for completion timeouts or descriptor allocation errors before
the completion state is updated.

- Removes setsockopts for PNPIPE_CREATE and PNPIPE_DESTROY
- Adds setsockopt for setting the Pipe handle value
- Implements connect socket call
- Updates the Pipe controller logic
User-space should now follow below sequence with Pipe controller:-
-socket

-setsockopt for PNPIPE_PIPE_HANDLE
-connect
-setsockopt for PNPIPE_ENCAP_IP
-setsockopt for PNPIPE_ENABLE

Currently we set all skbs with CHECKSUM_UNNECESSARY, even
those whose protocol we don't know. This patch just
add the CHECKSUM_COMPLETE tag for non TCP/UDP packets.

As of commit 43a9aa64a2f4330a9cb59aaf5c5636566bce067c "NFSD:
Fill in WCC data for REMOVE, RMDIR, MKNOD, and MKDIR", we sometimes call
fh_unlock on a filehandle that isn't fully initialized.
We should fix up the callers, but as a quick fix it is also sufficient
just to remove this assertion.
