A patch from Martin Bligh which cleans up the open-coded uses of mem_map for ia32. Basically it replaces mem_map + pagenr with pfn_to_page(pagenr) in lots of places. Because mem_map[] doesn't work like that with discontigmem. It also fixes a bug in bad_range, that happens to work for contig mem systems, but is incorrect. Tested both with and without discontigmem support.

- All the support macros which assume a linear mem_map[] have been wrapped in !CONFIG_DISCONTIGMEM. pfn_to_page, page_to_pfn, page_to_phys, pmd_page, kern_addr_valid. - Move some initialsation macros into setup.h so they can be used in the i386 discontig.c (INITRD_START, INITRD_SIZE). - Alternate version of the bootmem allocator - add i386 discontig support and numaq support.

- Pull the middle out of one_highpage_init() so that the i386 NUMA patch can call it on a per-page basis. - Move a few lines out of mem_init() into the new set_max_mapnr_init(), which the i386 NUMA code requires.

This restructures setup_arch() for i386 to make it easier to include the i386 numa changes (for CONFIG_DISCONTIGMEM) I've been working on. It also makes setup_arch() easier to read. A version of this patch is the in 2.4 aa tree. This does not depend on the other patches I'm submitting today, but my discontigmem patch does depend on this one. I've tested this patch on the following configurations: UP, SMP, SMP PAE, multiquad, multiquad PAE.

I've had ia32-discontigmem under test for a month, uneventfully. Possibly because I don't have a machine to test it on.... A major part of this work is a general move to convert the low-level memory management to consistently use pageframe numbers. It's a bit schizo at present.. This patch was written by Martin Bligh. A version of this patch is in the 2.4 aa tree. It changes the unsigned longs node_start_paddr and zone_start_paddr to page frame numbers. This is necessary because a PAE address is 36 bits and cannot be represented in an unsigned long. - The per-node physical memory start address node_start_paddr becomes a pfn, node_start_pfn. - The per-zone physical memory start address zone_start_paddr becomes a pfn, zone_start_pfn. - free_area_init_node() takes a pfn rather than a physical address. Patricia has tested this patch on the following configurations: UP, SMP, SMP PAE, multiquad, multiquad PAE, multiquad DISCONTIGMEM, multiquad DISCONTIGMEM PAE.

The rmap locking inlines are causing some header file dependency/ordering problems - move them out of page-flags.h and into their own header file.

OK, Linus, you are right... there are enough instances of this we are not going to find them all (although I suspect Andrew's slab.c fixes will cover most of the cases). Further, I think we can should actually purposely call preempt_schedule() in certain cases after interrupt reenable to check for reschedules... Let's just make it a rule "no preemption if interrupts are off" and enforce that.

This fixes various instances of the interrupt flag variable not being the proper `unsigned long', most notably kernel/softirq.c ...

This is a cleanup of the sigio/sigurg code. Summary: o Removed sk->proc, SIGURG now sent via vfs, credentials checked during delivery. o SIOCSPGRP etc. ioctls use vfs, and work now for SIGIO as well as SIGURG. o Removed socket fcntl code. o Consolidate lsm file_set_fowner() hooks. o Fixed fowner race. o Fixed associated mainline memory leak in fcntl_dirnotify().

This was _bad_. Major floppy corruption, and possibly the reason for other block device corruption for any driver that generated partial results for a block device request.

Defining CONFIG_DEVFS_FS in two different places does not work correctly. Nobody objected on linux-ia64, so I just removed the statements unconditionally enabling devfs on IA64/SNI. Pointed out by Greg Banks.
