      [PATCH] IDE cleanups (2.5; similar to ones done for other drivers) · 99db2bb5
      Alexander Viro authored
      	OK, before the next bunch of gendisk merges, here comes a couple
      of 2.5 IDE cleanups.
      
      	a) exclusion between rereading partition tables and open() is done
      in fs/block_dev.c these days, so homegrown one in ide.c is redundant - that
      code _never_ blocks now.  Removed, just as it had been done with counterparts
      in other drivers.
      
      	b) blk_ioctl() calls are done in blkdev_ioctl() now; driver doesn't
      need to handle them.  Again, removed as it had been done in all other drivers.

      Fix IO-APIC edge IRQ handling. IRQ_INPROGRESS was cleared spuriously · e42e97d6
      Linus Torvalds authored
      if a new edge happened while we were still processing the previous
      one.
      
      Then, if a _third_ edge came in, it would actually cause a reentrant
      irq handler invocation, because the original INPROGRESS bit was now
      lost.
      
      This was actually seen on IDE in PIO mode.

      [PATCH] fix create_elf_tables on PPC · 6860f192
      Paul Mackerras authored
      create_elf_tables in fs/binfmt_elf.c now sets up the list of aux table
      entries in a buffer on the kernel stack before copying it to the user
      stack.
      
      Unfortunately, while the buffer is big enough for most architectures, it
      isn't big enough on PPC, which uses 5 extra aux table entries (put on
      with ARCH_DLINFO).  The following patch increases the buffer to be big
      enough for PPC.  (Note that each aux table entry uses two elements of
      the elf_info array.)

      [PATCH] list_t removal · 97460db9
      Rusty Russell authored
      This removes list_t, which is a gratuitous typedef for a "struct
      list_head".  Unless there is good reason, the kernel doesn't usually
      typedef, as typedefs cannot be predeclared unlike structs.

      [PATCH] Important per-cpu fix. · bd0f8cb9
      Rusty Russell authored
      Frankly, I'm amazed the kernel worked for long without this.
      
      Every linker script thinks the section is called .data.percpu.
      Without this patch, every CPU ends up sharing the same "per-cpu"
      variable.
      
      This might explain the wierd per-cpu problem reports from Andrew and
      Dave, and also that nagging feeling that I'm an idiot...

      [PATCH] daemonize() calls reparent_to_init cleanup · 1350c3f2
      Rusty Russell authored
       This makes daemonize() call reparent_to_init() itself, as long
      suggested for 2.5, and fixes the callers so they don't call it again.
      Also fixes callers which set current->tty to NULL themselves (also
      no longer neccessary).

      [PATCH] Fix RELOC_HIDE miscompilation · efec05b7
      Andi Kleen authored
      RELOC_HIDE got miscompiled on gcc3.1/x86-64 in the access to softirq.c's per
      cpu variables.  This fixes the problem.
      
      Clearly to hide the relocation the addition needs to be done after the
      value obfuscation, not before.
      
      I don't know if it triggers on other architectures (x86-64 is especially
      stressf here because it has negative kernel addresses), but seems like the
      right thing to do.

      [PATCH] try more sd.c MODE SENSE modes · e91004e8
      Andries E. Brouwer authored
      In sd.c we call MODE SENSE (6) in order to find out whether the
      device is write protected. The info we need is in byte 2, the
      header of the MODE SENSE answer, but in the request we have to
      specify (i) what page(s) we want, and (ii) how many bytes we want.
      
      Long ago we asked for 12 bytes from page 1 (Daniel Roche, 1.3.35).
      Matthew Dharm made this 8 bytes from page 3F (all pages), patch-2.4.0-test8.
      In patch-2.4.10 the 8 was increased to 255.
      
      I found on the one hand devices that only react to page 0
      (the vendor page), and return an error for page 3F.
      And on the other hand devices that are unable to handle requests
      for more bytes than they actually have.
      
      So, it seems that the cautious way to ask for MODE SENSE data is
      to first ask for the header only, see how much is available,
      and then ask for everything.
      
      The patch below first separates out the MODE SENSE call,
      and then tries it three times: on all pages (3F), only the first
      four bytes; on the vendor page (0), only the first four bytes;
      on all pages (3F), 255 bytes.
      
      This should be at least as robust as our current code.
      I tried it on 8 SCSI devices (of which 2 fail under 2.5.33)
      and found no problems.

      [PATCH] use page_to_pfn() instead of mem_map[] · 27254059
      Andrew Morton authored
      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.

      [PATCH] discontigmem support for ia32 NUMA · 0d0bdc8e
      Andrew Morton authored
       - 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.

      [PATCH] reorganise setup_arch() for ia32 discontigmem · b9ba3a05
      Andrew Morton authored
      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.

      [PATCH] convert node/zone_start_paddr to pfns · 2589a05f
      Andrew Morton authored
      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.

      [PATCH] bad: schedule() with irqs disabled! · 1314cad1
      Robert Love authored
      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.

      [PATCH] sigio/sigurg cleanup for 2.5.32 · 1add9f7a
      James Morris authored
      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().
