2014-07-28powerpc: Remove misleading DISABLE_INTSMichael Ellerman
DISABLE_INTS has a long and storied history, but for some time now it has not actually disabled interrupts. For the open-coded exception handlers, just stop using it, instead call RECONCILE_IRQ_STATE directly. This has the benefit of removing a level of indirection, and making it clear that r10 & r11 are used at that point. For the addition case we still need a macro, so rename it to clarify what it actually does.

2014-07-28powerpc: Update comments in irqflags.hMichael Ellerman
The comment on TRACE_ENABLE_INTS is incorrect, and appears to have always been incorrect since the code was merged. It probably came from an original out-of-tree patch. Replace it with something that's correct. Also propagate the message to RECONCILE_IRQ_STATE(), because it's potentially subtle.

2014-07-28powerpc: Move bad_stack() below the fwnmi_data_areaMichael Ellerman
At the moment the allmodconfig build is failing because we run out of space between altivec_assist() at 0x5700 and the fwnmi_data_area at 0x7000. Fixing it permanently will take some more work, but a quick fix is to move bad_stack() below the fwnmi_data_area. That gives us just enough room with everything enabled. bad_stack() is called from the common exception handlers, but it's a non-conditional branch, so we have plenty of scope to move it further way.

2014-07-28powerpc: Remove CLASSIC_PPCMichael Ellerman
We have a strange #define in cputable.h called CLASSIC_PPC. Although it is defined for 32 & 64bit, it's only used for 32bit and it's basically a duplicate of CONFIG_PPC_BOOK3S_32, so let's use the latter.

2014-07-28powerpc: Remove CONFIG_POWER4Michael Ellerman
Although the name CONFIG_POWER4 suggests that it controls support for power4 cpus, this symbol is actually misnamed. It is a historical wart from the powermac code, which used to support building a 32-bit kernel for power4. CONFIG_POWER4 was used in that context to guard code that was 64-bit only. In the powermac code we can just use CONFIG_PPC64 instead, and in other places it is a synonym for CONFIG_PPC_BOOK3S_64.

2014-07-28powerpc: Remove CONFIG_POWER3Michael Ellerman

2014-07-28powerpc: Remove STAB codeMichael Ellerman
Old cpus didn't have a Segment Lookaside Buffer (SLB), instead they had a Segment Table (STAB). Now that we've dropped support for those cpus, we can remove the STAB support entirely.

2014-07-28powerpc: Drop support for pre-POWER4 cpusMichael Ellerman
We inadvertently broke power3 support back in 3.4 with commit f5339277eb8d "powerpc: Remove FW_FEATURE ISERIES from arch code". No one noticed until at least 3.9. By then we'd also broken it with the optimised memcpy, copy_to/from_user and clear_user routines. We don't want to add any more complexity to those just to support ancient cpus, so it seems like it's a good time to drop support for power3 and earlier.

2014-07-28powerpc: Use standard macros for sys_sigpending() & sys_old_getrlimit()Michael Ellerman
Currently we have sys_sigpending and sys_old_getrlimit defined to use COMPAT_SYS() in systbl.h, but then both are #defined to sys_ni_syscall in systbl.S. This seems to have been done when ppc and ppc64 were merged, in commit 9994a33 "Introduce entry_{32,64}.S, misc_{32,64}.S, systbl.S". AFAICS there's no longer (or never was) any need for this, we can just use SYSX() for both and remove the #defines to sys_ni_syscall. The expansion before was: #define COMPAT_SYS(func) .llong .sys_##func,.compat_sys_##func #define sys_old_getrlimit sys_ni_syscall COMPAT_SYS(old_getrlimit) => .llong .sys_old_getrlimit,.compat_sys_old_getrlimit => .llong .sys_ni_syscall,.compat_sys_old_getrlimit After is: #define SYSX(f, f3264, f32) .llong .f,.f3264 SYSX(sys_ni_syscall, compat_sys_old_getrlimit, sys_old_getrlimit) => .llong .sys_ni_syscall,.compat_sys_old_getrlimit ie. they are equivalent. Finally both COMPAT_SYS() and SYSX() evaluate to sys_ni_syscall in the Cell SPU code.

2014-07-28powerpc: Fix endianness of flash_block_list in rtas_flashThomas Falcon
The function rtas_flash_firmware passes the address of a data structure, flash_block_list, when making the update-flash-64-and-reboot rtas call. While the endianness of the address is handled correctly, the endianness of the data is not. This patch ensures that the data in flash_block_list is big endian when passed to rtas on little endian hosts.
