2006-08-19[PATCH] ppc32: board-specific part of fs_enet updateVitaly Bordug
This contains board-specific portion to respect driver changes (for 8272ads , 885ads and 866ads). Altered platform_data structures as well as initial setup routines relevant to fs_enet. Changes to the mpc8560ads ppc/ code are also introduced, but mainly as reference, since the entire board support is going to appear in arch/powerpc.

2006-08-17[POWERPC] kprobes: Fix possible system crash during out-of-line single-steppingAnanth N Mavinakayanahalli
- On archs that have no-exec support, we vmalloc() a executable scratch area of PAGE_SIZE and divide it up into an array of slots of maximum instruction size for that arch - On a kprobe registration, the original instruction is copied to the first available free slot, so if multiple kprobes are registered, chances are, they get contiguous slots - On POWER4, due to not having coherent icaches, we could hit a situation where a probe that is registered on one processor, is hit immediately on another. This second processor could have fetched the stream of text from the out-of-line single-stepping area *before* the probe registration completed, possibly due to an earlier (and a different) kprobe hit and hence would see stale data at the slot. Executing such an arbitrary instruction lead to a problem as reported in LTC bugzilla 23555. The correct solution is to call flush_icache_range() as soon as the instruction is copied for out-of-line single-stepping, so the correct instruction is seen on all processors. Thanks to Will Schmidt who tracked this down.

2006-08-17[POWERPC] Make secondary CPUs call into kdump on reset exceptionDavid Wilder
In the case of a system hang, the user will invoke soft-reset to initiate the kdump boot. If xmon is enabled, the CPU(s) enter into the xmon debugger. Unfortunately, the secondary CPU(s) will return to the hung state when they exit from the debugger (returned from die() -> system_reset_exception()). This causes a problem in kdump since the hung CPU(s) will not respond to the IPI sent from kdump. This patch fixes the issue by calling crash_kexec_secondary() directly from system_reset_exception() without returning to the previous state. These secondary CPUs wait 5ms until the kdump boot is started by the primary CPU. In the case we exited from the debugger to "recover" (command 'x' in xmon) the primary and the secondary CPUs will all return from die() -> system_reset_exception() ->crash_kexec_secondary() wait 5ms, then return to the previous state. A kdump boot is not started in this case. Signed-off-by: Haren Myneni <haren@us.ibm.com> Signed-off-by: David Wilder <dwilder@us.ibm.com> Signed-off-by: Paul Mackerras <paulus@samba.org>

Previously the message was "Fatal exception: panic_on_oops", as introduced in a recent patch whith removed a somewhat dangerous call to ssleep() in the panic_on_oops path. However, Paul Mackerras suggested that this was somewhat confusing, leadind people to believe that it was panic_on_oops that was the root cause of the fatal exception.

2006-08-02[IA64] Do not assume output registers be reservered.Zou Nan hai
We found an issue in pal.S. According to the software runtime SPEC, The caller's output registers do not need to be preserved for caller. The callee may reuse input registers for any other purpose within the procedure. in ia64_pal_call_phys_stacked, input registers are copied to output registers before call into ia64_switch_mode_phys, then used to call into PAL. This assumes output registers are preserved in ia64_switch_mode_phys, which may not be true. In this particular case, ia64_switch_mode_phys alloc a null frame , and mask off psr.i. If an interrupt comes at this small window, or an MCA comes inside the procedure, output registers maybe changed, then the pal call may got some staled input registers. This patch moves the copies from input to output after ia64_switch_mode_phys to follow the software runtime convention. It also removed some unused labels in ia64_pal_call_phys_stacked.

There is no need to worry about local APIC. There is need to worry about I/O APIC, because I/O APIC is replacing good old 8259. According to Nehemiah datasheet VIA is using 3-wire bus to connect local APIC to I/O APIC. "[...] When IA32_APIC_BASE[11] is set to 0, processor APICs based on the 3-wire APIC bus cannot be generally re-enabled until a system hardware reset. The 3-wire bus looses track of arbitration that would be necessary for complete re-enabling. Certain (local) APIC functionality can be enabled. [...]" So we must set disable bit for each interrupt in I/O APIC registers. Same situation as for PIC - we must poke registers direcly. How to do this? I don't know. So at the moment it is better to fail. Signed-off-by: Rafa³ Bilski <rafalbilski@interia.pl> Signed-off-by: Dave Jones <davej@redhat.com>
2006-07-31[CPUFREQ] Longhaul - Hook into ACPI C states.Rafa³ Bilski
Minimal change necessary for hardware support. Changes in longhaul.c: - most important - now C3 state is causing transition, - code responsible for clearing "bus master" bit removed, - protect bcr2 transition in the same way as longhaul.

2006-07-31[PATCH] powermac: More powermac backlight fixesMichael Hanselmann
This patch fixes several problems: - The legacy backlight value might be set at interrupt time. Introduced a worker to prevent it from directly calling the backlight code. - via-pmu allows the backlight to be grabbed, in which case we need to prevent other kernel code from changing the brightness. - Don't send PMU requests in via-pmu-backlight when the machine is about to sleep or waking up. - More Kconfig fixes.
