* [PATCH] ppc32: board-specific part of fs_enet updateVitaly Bordug2006-08-19
| | | | | | | | | | | | | 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.

| * [POWERPC] Fix irq radix tree remapping typoBenjamin Herrenschmidt2006-08-17
| | | | | | | | | | | | | | | | | | | | The code for using the radix tree for reverse mapping of interrupts has a typo that causes it to create incorrect mappings if the software and hardware numbers happen to be different. This would, among others, cause the IDE interrupt to fail on js20's. This fixes it. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Paul Mackerras <paulus@samba.org>
| * [POWERPC] kprobes: Fix possible system crash during out-of-line single-steppingAnanth N Mavinakayanahalli2006-08-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - 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.

| * [POWERPC] Make secondary CPUs call into kdump on reset exceptionDavid Wilder2006-08-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

On his suggestion, this patch changes the message to simply "Fatal exception". A suitable oops message should already have been displayed.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

The potentially large MAX_ORDER on ia64 (due to hugetlbfs) requires that the end of vmem_map be aligned to MAX_ORDER_NR_PAGES. This was boot tested for: FLATMEM, FLATMEM+VIRTUAL_MEM_MAP, DISCONTIGMEM+VIRTUAL_MEM_MAP and SPARSEMEM. Signed-off-by: Bob Picco <bob.picco@hp.com> Signed-off-by: Tony Luck <tony.luck@intel.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I think ia64_switch_mode_phys and ia64_switch_mode_virt does not need to alloc an empty frame.

| * | [IA64] Do not assume output registers be reservered.Zou Nan hai2006-08-02

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.

| * | [IA64] Format /proc/pal/*/version_info correctlyMatthew Wilcox2006-07-31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | /proc/pal/*/version_info is a bit confusing. HP firmware, at least, reports 07.31 instead of 0.7.31. Also, the comment is out of place; it's an internal detail about the implementation of ia64_pal_version. Since the 2.2 revision of the SDM still states that PAL_VERSION can be called in virtual mode, correct the comment to be more accurate.

In the case where no HW IOMMU is present in the machine and we end up using nommu, leaving force_iommu set to 1 causes dma_alloc_coherent to do the wrong thing. Therefore, if we end up using nommu, make sure force_iommu is 0.
