103be64c26 target/mips: Add CP0 PWCtl register
Add PWCtl register (CP0 Register 5, Select 6).

The PWCtl register configures hardware page table walking for TLB
refills.

This register is required for the hardware page walker feature. It
exists only if Config3 PW bit is set to 1. It contains following
fields:

PWEn     (31)   - Hardware Page Table walker enable
PWDirExt (30)   - If 1, 4-th level implemented (MIPS64 only)
XK       (28)   - If 1, walker handles xkseg (MIPS64 only)
XS       (27)   - If 1, walker handles xsseg (MIPS64 only)
XU       (26)   - If 1, walker handles xuseg (MIPS64 only)
DPH      (7)    - Dual Page format of Huge Page support
HugePg   (6)    - Huge Page PTE supported in Directory levels
PSn      (5..0) - Bit position of PTEvld in Huge Page PTE

f0a997c6b9 elf: Fix comments to EF_MIPS_MACH_xxx constants
Regarding R5900 CPU, some sources indicate that the Emotion Engine
ISA/ASE was designed by Toshiba and licensed to Sony. Others sources
claim it was a joint effort. It therefore makes sense to refer to
the CPU as "Toshiba/Sony R5900".

Also, remove and "'s" in the line for some other CPU, for the sake
of consistency.

such old versions of GCC anymore, but since Clang 3.4 is still

5f538f7532 target/hppa: Raise exception 26 on emulated hardware
On PCXS chips (PA7000, pa 1.1a), trap #18 is raised on memory faults,
while all later chips (>= PA7100) generate either trap #26, #27 or #28
(depending on the fault type).

Since the current qemu emulation emulates a B160L machine (with a
PA7300LC PCX-L2 chip, we should raise trap #26 (EXCP_DMAR) instead
of #18 (EXCP_DMP) on access faults by the Linux kernel to page zero.

With the patch we now get the correct output (I tested against real
hardware):
 Kernel Fault: Code=26 (Data memory access rights trap)
instead of:
 Kernel Fault: Code=18 (Data memory protection/unaligned access trap)

2ef297af07 coccinelle: new inplace-byteswaps.cocci to remove inplace-byteswapping calls
Add a new Coccinelle script which replaces uses of the inplace
byteswapping functions *_to_cpus() and cpu_to_*s() with their
not-in-place equivalents. This is useful for where the swapping
is done on members of a packed struct -- taking the address
of the member to pass it to an inplace function is undefined
behaviour in C.

ab44c7b71f target/arm: Initialize ARMMMUFaultInfo in v7m_stack_read/write
The get_phys_addr() functions take a pointer to an ARMMMUFaultInfo
struct, which they fill in only if a fault occurs. This means that
the caller must always zero-initialize the struct before passing
it in. We forgot to do this in v7m_stack_read() and v7m_stack_write().
Correct the error.
