* [IA64] min_low_pfn and max_low_pfn calculation fixZou Nan hai2007-03-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We have seen bad_pte_print when testing crashdump on an SN machine in recent 2.6.20 kernel. There are tons of bad pte print (pfn < max_low_pfn) reports when the crash kernel boots up, all those reported bad pages are inside initmem range; That is because if the crash kernel code and data happens to be at the beginning of the 1st node. build_node_maps in discontig.c will bypass reserved regions with filter_rsvd_memory. Since min_low_pfn is calculated in build_node_map, so in this case, min_low_pfn will be greater than kernel code and data. Because pages inside initmem are freed and reused later, we saw pfn_valid check fail on those pages. I think this theoretically happen on a normal kernel. When I check min_low_pfn and max_low_pfn calculation in contig.c and discontig.c. I found more issues than this. 1. min_low_pfn and max_low_pfn calculation is inconsistent between contig.c and discontig.c, min_low_pfn is calculated as the first page number of boot memmap in contig.c (Why? Though this may work at the most of the time, I don't think it is the right logic). It is calculated as the lowest physical memory page number bypass reserved regions in discontig.c. max_low_pfn is calculated include reserved regions in contig.c. It is calculated exclude reserved regions in discontig.c. 2. If kernel code and data region is happen to be at the begin or the end of physical memory, when min_low_pfn and max_low_pfn calculation is bypassed kernel code and data, pages in initmem will report bad. 3. initrd is also in reserved regions, if it is at the begin or at the end of physical memory, kernel will refuse to reuse the memory. Because the virt_addr_valid check in free_initrd_mem. So it is better to fix and clean up those issues. Calculate min_low_pfn and max_low_pfn in a consistent way.

| * [IA64] Proper handling of TLB errors from duplicate itr.d dropinsRuss Anderson2007-03-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Jack Steiner noticed that duplicate TLB DTC entries do not cause a linux panic. See discussion: http://www.gelato.unsw.edu.au/archives/linux-ia64/0307/6108.html The current TLB recovery code is recovering from the duplicate itr.d dropins, masking the underlying problem. This change modifies the MCA recovery code to look for the TLB check signature of the duplicate TLB entry and panic in that case.

As such, the tables may have to change at kernel boot time. By default, prior to kernel boot, the PROM builds an empty DSDT (header only) and no SSDTs. If an ACPI capable kernel boots, the kernel will notify the PROM, at platform setup time, and the PROM will build full DSDT and SSDT tables. With the latest changes to acpi_table_init(), the table lengths are saved, and when our PROM changes them, the changes are not seen, and the kernel will crash on boot. Because of issues with kexec support, we are not able to create the tables prior to acpi_table_init(). As a result, we are making a second call to acpi_table_init() to process the rebuilt DSDT and SSDTs. Signed-off-by: John Keller <jpk@sgi.com> Signed-off-by: Len Brown <len.brown@intel.com>

A process calling arch_prctl to set %fs would lose it on the next context switch. It also turns out that you can switch to a process which is in the process of exiting and which has lost its mm. In this case, it's worse than useless to try to call arch_prctl on the host process.

| * | | [IA64] Pick highest possible saved_max_pfn for crash_dumpTony Luck2007-03-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Berhhard Walle noted that on his HP rx8640 he ended up with saved_max_pfn smaller than the highest address of system ram in /proc/iomem and proposed a patch to base the address on the unrounded and unfiltered EFI memory map address. Simon Horman and Magnus Damm suggested that the whole test be moved earlier in the function. This is the combination of both of these patches. Signed-off-by: Tony Luck <tony.luck@intel.com>

| |/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes boot failure because irq_desc->mask() is NULL. - Added mask/unmask functions to ia64's irq desc function table. - rename hw_interrupt_type to irq_chip. hw_interrupt_type is old name. - Tony: Added same change to arch/ia64/sn/kernel/irq.c as pointed out by Eric Biederman ... mask/unmask functions there can be no-op.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | flush_icache_page() can be called from atomic context, so we can't use kmap(). Use page_address() instead. Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We should OR in a bitmask, not a bit offset, into ti->flags. This might fix some strange behaviour when single stepping. Also, use set_ti_thread_flag() to manipulate the flags to avoid surprises in the future.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Terminate the frame pointer walk if (a) the address is outside the task's kernel stack or (b) if the frame pointer isn't monotonically increasing. Without this fix, show_trace() may enter an infinite loop, walking through random data anywhere in memory. Since any address within the kernel stack is guaranteed to be valid, we may eliminate the __get_user() calls as well. Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>
