| * [PATCH] ppc64: Fix the lazy icache/dcache code for non-RAM pagesBenjamin Herrenschmidt2005-11-081-0/+3
| | | | | | | | | | | | | | | | | | | | For some stupid reason I can't explain (brown paper bag is at hand), I removed the check pfn_valid() in the code that does the icache/dcache coherency on POWER4 and later. That causes us to eventually try to access non existing struct page when hashing in IO pages.

This seems to be done in other parts of the Kconfig file. Using those as an example, this should keep the MAX_ORDER block size at 16MB.

| | | | | | | | | | | | | | | | | | | | | | | | Even though we can enable and disable xmon at runtime now, there are a few places in the merge tree that call xmon and xmon_printf directly. In the case below we call die() which will call xmon if it is enabled. Also remove an unnecessary include of xmon.h in smp.c.

| | | | | | | | | | | | | | | | | | | | Oprofile was hardwiring the MMCRA sample bit to 1 but on newer cpus (eg POWER5) we want to vary it based on the group being sampled.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On ppc64 we end up with a negative value for the data size in the memory boot message: Memory: 2035560k/2097152k available (5792k kernel code, 89564k reserved, 18014398509481632k data, 870k bss, 352k init) It turns out the section ordering of the linker script is different on ppc32 and ppc64, so just count data as _edata - _sdata which should work on both.

First, in the hash setup code, one of the bits allows the size of the hash table to be reduced by a factor of 8 - which would be better accomplished with a command line option for that purpose. The other was a bunch of bus walking related messages in the iSeries code, which would seem to be insufficient reason to keep the mechanism. This patch removes the last traces of this mechanism.

This seems to be a private affair between switch_mm and activate_mm, using page_table_lock as a per-mm lock, without any relation to its uses elsewhere. That's fine, but comment it as such; and unlock sooner in switch_mm, more like in activate_mm (preemption is disabled here). There is a block of "if (0)"ed code in smp_flush_tlb_pending which would have liked to rely on the page_table_lock, in switch_mm and elsewhere; but its comment explains how dup_mmap's flush_tlb_mm defeated it. And though that could have been changed at any time over the past few years, now the chance vanishes as we push the page_table_lock downwards, and perhaps split it per page table page. Just delete that block of code. Which leaves the mysterious spin_unlock_wait(&oldmm->page_table_lock) in kernel/fork.c copy_mm. Textual analysis (supported by Nick Piggin) suggests that the comment was written by DaveM, and that it relates to the defeated approach in the sparc64 smp_flush_tlb_pending.
