| * [ARM] Fix freeing of page tables for ARM in free_pgd_slowUwe Kleine-König2008-03-01
| | | | | | | | | | | | | | | | | | | | | | | | Since 2f569af (CONFIG_HIGHPTE vs. sub-page page tables.) pte_free() calls pte_lock_deinit() and dec_zone_page_state(). So free_pgd_slow must not call the latter two when calling the first.

| * | | [POWERPC] Convert the cell IOMMU fixed mapping to 16M IOMMU pagesMichael Ellerman2008-03-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The only tricky part is we need to adjust the PTE insertion loop to cater for holes in the page table. The PTEs for each segment start on a 4K boundary, so with 16M pages we have 16 PTEs per segment and then a gap to the next 4K page boundary. It might be possible to allocate the PTEs for each segment separately, saving the memory currently filling the gaps. However we'd need to check that's OK with the hardware, and that it actually saves memory. Signed-off-by: Michael Ellerman <michael@ellerman.id.au> Signed-off-by: Arnd Bergmann <arnd@arndb.de>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Make some preliminary changes to cell_iommu_alloc_ptab() to allow it to take the page size as a parameter rather than assuming IOMMU_PAGE_SIZE.

| * | | [POWERPC] Cell IOMMU: n_pte_pages is in 4K page units, not IOMMU_PAGE_SIZEMichael Ellerman2008-03-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We use n_pte_pages to calculate the stride through the page tables, but we also use it to set the NPPT value in the segment table entry. That is defined as the number of 4K pages per segment, so we should calculate it as such regardless of the IOMMU page size.

| * | | [POWERPC] Split setup of IOMMU stab and ptab, allocate dynamic/fixed ptabs ↵Michael Ellerman2008-03-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | separately Currently the cell IOMMU code allocates the entire IOMMU page table in a contiguous chunk. This is nice and tidy, but for machines with larger amounts of RAM the page table allocation can fail due to it simply being too large. So split the segment table and page table setup routine, and arrange to have the dynamic and fixed page tables allocated separately.

This takes into account the SPIDER_DMA_OFFSET which sets the top bit of every DMA address. However it doesn't cater for the IOMMU window starting at a non-zero address, as the base of the window is not incorporated into pte_offset at all. As it turns out tbl->it_offset already contains the value we need, it takes into account the base of the window and also pte_offset. So use it instead!

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | avoid over-eager large page splitup. When the target area needs to be split or is split already (ioremap) then the current code enforces the split of large mappings in the alias regions even if we could avoid it. Use a separate variable processed in the cpa_data structure to carry the number of pages which have been processed instead of reusing the numpages variable. This keeps numpages intact and gives the alias code a chance to keep large mappings intact. Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Signed-off-by: Ingo Molnar <mingo@elte.hu>

This was addressed in commit 03994f01e8b72b3d01fd3d09d1cc7c9f421a727c by using [:alnum:] in place of [a-zA-Z0-9]. But that solution too is locale-dependent and may not always match the identifiers it needs to. The better fix is just to run sed et al with a fixed locale setting in all builds.

Otherwise, the TIF_DEBUG flag must be unset. Currently, the child inherits TIF_DEBUG from the parent before copy_thread is called, so TIF_DEBUG may be already be set before we determine whether the child is supposed to inherit debugging capabilities from the parent or not. This means that ocd_enable() won't increment the refcount, because TIF_DEBUG is already set, and that TIF_DEBUG will be set for processes that aren't being debugged. This leads to a refcounting asymmetry, which may show up as ------------[ cut here ]------------ Badness at arch/avr32/kernel/ocd.c:73 PC is at ocd_disable+0x34/0x60 LR is at put_lock_stats+0xa/0x20 as reported by David Brownell.
