Setting DEC to maximum at the start of the timer interrupt is not
necessary and can be avoided for performance when MSR[EE] is not
enabled during the handler as explained in commit 0faf20a1ad16
("powerpc/64s/interrupt: Don't enable MSR[EE] in irq handlers unless
perf is in use"), where this change was first attempted.
The idea is that the timer interrupt runs with MSR[EE]=0, and at the end
of the interrupt DEC is programmed to the next timer interval, so there
is no need to clear the decrementer exception before then.
When the above commit was merged, that was not quite true. The low res
timer subsystem had some cases in the oneshot timer code where if the
tick was to be stopped and no timers active, the clock device would not
get the ->set_state_oneshot_stopped() call, so DEC would not get
reprogrammed, and this would hang taking continual timer interrupts.
So this was reverted in commit d2b9be1f4af5 ("powerpc/time: Always set
decrementer in timer_interrupt()"), which was a partial revert of the
above commit.
Commit 62c1256d5447 ("timers/nohz: Switch to ONESHOT_STOPPED in the
low-res handler when the tick is stopped") was later merged to fix this
missing case in the timer subsystem, so now the behaviour can be
restored.

Currently powerpc early debugging contains lot of platform specific
options, but does not support standard UART / serial 16550 console.
Later legacy_serial.c code supports registering UART as early debug console
from device tree but it is not early during booting, but rather later after
machine description code finishes.
So for real early debugging via UART is current code unsuitable.
Add support for new early debugging option CONFIG_PPC_EARLY_DEBUG_16550
which enable Serial 16550 console on address defined by new option
CONFIG_PPC_EARLY_DEBUG_16550_PHYSADDR and by stride by option
CONFIG_PPC_EARLY_DEBUG_16550_STRIDE.
With this change it is possible to debug powerpc machine descriptor code.
For example this early debugging code can print on serial console also
"No suitable machine description found" error which is done before
legacy_serial.c code.

Since commit e641eb03ab2b0 ("powerpc: Fix up the kdump base cap to
128M") memory for kdump kernel has been reserved at an offset of 128MB.
This held up well for a long time before running into boot failure on
LPARs having a lot of cores. Commit 7c5ed82b800d8 ("powerpc: Set
crashkernel offset to mid of RMA region") fixed this boot failure by
moving the offset to mid of RMA region. This change meant the offset is
either 256MB or 512MB on LPARs as ppc64_rma_size was 512MB or 1024MB
owing to commit 103a8542cb35b ("powerpc/book3s64/ radix: Fix boot
failure with large amount of guest memory").
But ppc64_rma_size can be larger as well with newer f/w. So, limit
crashkernel reservation offset to 512MB to avoid running into boot
failures during kdump kernel boot, due to RTAS or other allocation
restrictions.
Also, while here, use SZ_128M instead of opening coding it.

Implement syscall wrapper as per s390, x86, arm64. When enabled
cause handlers to accept parameters from a stack frame rather than
from user scratch register state. This allows for user registers to be
safely cleared in order to reduce caller influence on speculation
within syscall routine. The wrapper is a macro that emits syscall
handler symbols that call into the target handler, obtaining its
parameters from a struct pt_regs on the stack.
As registers are already saved to the stack prior to calling
system_call_exception, it appears that this function is executed more
efficiently with the new stack-pointer convention than with parameters
passed by registers, avoiding the allocation of a stack frame for this
method. On a 32-bit system, we see >20% performance increases on the
null_syscall microbenchmark, and on a Power 8 the performance gains
amortise the cost of clearing and restoring registers which is
implemented at the end of this series, seeing final result of ~5.6%
performance improvement on null_syscall.
Syscalls are wrapped in this fashion on all platforms except for the
Cell processor as this commit does not provide SPU support. This can be
quickly fixed in a successive patch, but requires spu_sys_callback to
allocate a pt_regs structure to satisfy the wrapped calling convention.

Change system_call_exception arguments to pass a pointer to a stack
frame container caller state, as well as the original r0, which
determines the number of the syscall. This has been observed to yield
improved performance to passing them by registers, circumventing the
need to allocate a stack frame.

Cause syscall handlers to be typed as follows when called indirectly
throughout the kernel. This is to allow for better type checking.
typedef long (*syscall_fn)(unsigned long, unsigned long, unsigned long,
unsigned long, unsigned long, unsigned long);
Since both 32 and 64-bit abis allow for at least the first six
machine-word length parameters to a function to be passed by registers,
even handlers which admit fewer than six parameters may be viewed as
having the above type.
Coercing syscalls to syscall_fn requires a cast to void* to avoid
-Wcast-function-type.
Fixup comparisons in VDSO to avoid pointer-integer comparison. Introduce
explicit cast on systems with SPUs.

Arch-specific implementations of syscall handlers are currently used
over generic implementations for the following reasons:
1. Semantics unique to powerpc
2. Compatibility syscalls require 'argument padding' to comply with
64-bit argument convention in ELF32 abi.
3. Parameter types or order is different in other architectures.
These syscall handlers have been defined prior to this patch series
without invoking the SYSCALL_DEFINE or COMPAT_SYSCALL_DEFINE macros with
custom input and output types. We remove every such direct definition in
favour of the aforementioned macros.
Also update syscalls.tbl in order to refer to the symbol names generated
by each of these macros. Since ppc64_personality can be called by both
64 bit and 32 bit binaries through compatibility, we must generate both
both compat_sys_ and sys_ symbols for this handler.
As an aside:
A number of architectures including arm and powerpc agree on an
alternative argument order and numbering for most of these arch-specific
handlers. A future patch series may allow for asm/unistd.h to signal
through its defines that a generic implementation of these syscall
handlers with the correct calling convention be emitted, through the
__ARCH_WANT_COMPAT_SYS_... convention.

Example usage:
tc filter add dev $PF parent ffff: flower skip_sw \
action mirred egress mirror dev $VFREP
tc filter add dev $VFREP parent ffff: flower skip_sw \
action mirred egress redirect dev $PF
gives a VF unfiltered access to the network out the physical port ($PF
