The PAPR says that the property for specifying the number of SLBs should
be called "slb-size". We currently only look for "ibm,slb-size" because
this is what firmware actually presents.This patch makes us look for the "slb-size" property as well and in
preference to the "ibm,slb-size". This should future proof us if
firmware changes to match PAPR.Signed-off-by: Michael Neuling

powerpc: is_hugepage_only_range() must account for both 4kB and 64kB slices
The subpage_prot syscall fails on second and subsequent calls for a given
region, because is_hugepage_only_range() is mis-identifying the 4 kB
slices when the process has a 64 kB page size.Signed-off-by: Dave Kleikamp

We just fix up the reference parameters as the others are dealt with by
arithmetic promotion rules and don't cause warnings.This removes warnings like this:

FSL U-Boots use /soc8315@e0000000 node to search and fixup serial
nodes' clock-frequency properties. Though in upstream kernels we use
new naming convention -- for IMMR address space dts files specify
/immr@e0000000 nodes.This makes FSL U-Boots fail to fixup the clock frequencies, and that
leads to serial ports misbehaviour. We can workaround the issue by
filling the clock frequency values manually.p.s. For the same reason FSL U-Boots fail to fixup MAC addresses for
ethernet nodes, so users should either change the .dts file locally
or set MAC address via `ifconfig hw ether' command.Signed-off-by: Anton Vorontsov

The PowerMac kernel occasionally fails to bring up the secondary CPUs on
SMP, the trigger factor seem to be fairly random and related to location
of code and data.This appears to be due to the initial loading of the TOC value by the
secondary processor which now happens before we clear HID4:RM_CI (Real
Mode Cache Invalidate). This bit should really be cleared before we do
any load or store other than fetching code.This fix works based on the assumption that all SMP 64-bit PowerMacs use
variants of the 970, which fortunately is true, by explicitely clearing
that bit, adding an slbia for good measure as RM_CI mode is known to
create bogus ERAT entries.I also removed some spurrious debug output that was left enabled by
mistake while at it.Signed-off-by: Benjamin Herrenschmidt

Convert arch/powerpc/ over to long long based u64:
-#ifdef __powerpc64__
-# include
-#else
-# include
-#endif
+#includeThis will avoid reoccuring spurious warnings in core kernel code that
comes when people test on their own hardware. (i.e. x86 in ~98% of the
cases) This is what x86 uses and it generally helps keep 64-bit code
32-bit clean too.[Adjusted to not impact user mode (from paulus) - sfr]

Enforce that the crash kernel region never overlaps the current kernel,
as it will be written directly on kexec load.Also, default to the previous KDUMP_KERNELBASE if the start is 0.
Other architectures (x86, ia64) state that specifying the start address
0 (or omitting it) will result in the kernel allocating it. Before the
relocatable patch in 2.6.28, powerpc would adjust any other start value
to the hardcoded KDUMP_KERNELBASE of 32M.Signed-off-by: Milton Miller

Support for the FPGA based watchdog timer on GE Fanuc's SBC610.
This patch enables one of the watchdog timers found on the SBC610. There are
two identical watchdog timers at different offsets in the above mentioned
boards, however the current driver is only capable of supporting one of them.The watchdog timers are also capable of generating interrupts at a
user-configurable threshold, though support for this operation is currently
not supported by the driver.Signed-off-by: Martyn Welch

This patch adds the SPU event based profiling funcitonality for the
IBM Cell processor. Previously, the CELL OProfile kernel code supported
PPU event, PPU cycle profiling and SPU cycle profiling. The addition of
SPU event profiling allows the users to identify where in their SPU code
various SPU evnets are occuring. This should help users further identify
issues with their code. Note, SPU profiling has some limitations due to HW
constraints. Only one event at a time can be used for profiling and SPU event
profiling must be time sliced across all of the SPUs in a node.The patch adds a new arch specific file to the OProfile file system. The
file has bit 0 set to indicate that the kernel supports SPU event profiling.
The user tool must check this file/bit to make sure the kernel supports
SPU event profiling before trying to do SPU event profiling. The user tool
check is part of the user tool patch for SPU event profiling.Signed-off-by: Carl Love
