Linux 2.4.24-pre1

Hi, 

Here goes 2.4.24-pre1... 

The XFS filesystem has been merged.

This release contains mostly architecture specific updates.


Summary of changes from v2.4.23 to v2.4.24-pre1
============================================

<alex.williamson:hp.com>:
  o ia64: make hpzx1 fake pci device safer

<aspicht:arkeia.com>:
  o ac97_plugin_ad1980 fixes

<bjorn.helgaas:hp.com>:
  o ia64: Remove platform_pci_enable_device() machine vector and
  synchronize sba_iommu.c with 2.5. 
  o ia64: Bail out of SBA init function if no IOC found.  Avoids spurious
  (but harmless) "No IOC for PCI Bus 0000:00 in ACPI" messages when booting
  generic kernel on non-ZX1 hardware. 
  o ia64: Clear corrected errors (CMCs and CPEs) in the kernel
  o ia64: The "HP_ZX1" kernel works on sx1000-based machines as well as
  zx1-based ones, so make the descriptions a little more generic. 
  o ia64: add kmap_types.h to make crypto, etc compile.  (This is just a
  dummy file from 2.6 and shouldn't ever be used.) 
  o ia64: fix EFI memory map trimming
  o Cset exclude: kaos@sgi.com[helgaas]|ChangeSet|20031030215302|13517
  o ia64: update default configs

  o Support for delayed allocation.  Used by XFS and backported from 2.6
  o Provide a simple try-lock based dirty page flushing routine
  o Provide an iget variant without unlocking the inode and without the
  read_inode call (iget_locked).  Used by XFS and backported from 2.6. 
  o Export several kernel symbols used by the XFS filesystem
  o Add XFS documentation and incorporate XFS into the kernel build

<pavlin:icir.org>:
  o [RTNETLINK]: Add RTPROT_XORP

<pp:ee.oulu.fi>:
  o 2.4 lacks dummy SET_NETDEV_DEV

<tes:sgi.com>:

Chris Mason:
  o From -aa tree: Fix end_buffer_io_kiobuf() locking

Chuck Lever:
  o Make readahead last page of file

David Hinds:
  o update/bugfix for pcnet_cs driver

David Mosberger:
  o ia64: In <asm-ia64/param.h>, do not include
  <linux/config.h> outside the #ifdef __KERNEL__ bracket.  Doing so
  pollutes the user- level namespace.  Bug report & proposed fix by
  GOTO Masanori. 
  o ia64: Control /proc/bus/mckinley/zx1 via separate SBA_PROC_FS macro and
  turn SBA_PROC_FS off by default (it's too much of a scalability
  bottleneck). 
  o ia64: Mark access_ok() as likely to succeed (as is done in x86 tree)
  o ia64: Fix efi_mem_type() and efi_mem_attributes() to avoid potential
  underflows.  In my case, the underflows occurred with the first memory
  descriptor which got trimmed down to a size of 0. 
  o ia64: Fix a alternate-signal-stack bug which could corrupt RNaT bits
  when bspstore happened to point to an RNaT-slot. 
  o ia64: Fix a bug in sigtramp() which corrupted ar.rnat when unwinding
  across a signal trampoline (in user space).  Reported by Laurent
  Morichetti.

  o [XFS] Use i_size_read/i_size_write semantics from 2.6 kernel to reduce
  2.4/2.6 differences in xfs 
  o [XFS] Use buffer head flag set/clear routines as in 2.6 kernel to
  reduce 2.4/2.6 differences in xfs 
  o [XFS] Remove a nested transaction in xfs_dm_punch_hole
  o [XFS] BH_Sync added in 2.4.22, put an #ifdef in for now so this still
  works on older kernels. 
  o [XFS] Fix a few sysctls - values are all ints, but sysctl table was

Glen Overby:
  o [XFS] A problem was found with the debug code in
  xlog_state_do_callback.  At the end of processing all log buffers that
  can be processed, there is a (debug only) double-check to make sure that
  log buffers with completed I/O don't get marooned when the function
  completes.  The check only needs to go to the first buffer that will
  cause an I/O completion, that has not completed.  The loop doesn't stop a
  WANT_SYNC state buffer is found, but it should. 
  o [XFS] xfs_dir2_node_addname_int had reminants of an old block placement
  algorithm in it.  The old algorithm appeared to look for the first place
  to put a new data block, and thus a new freespace block (this is where
  the 'foundindex' variable came from).  However, new space in a directory
  is always added at the lowest file offset as determined by the extent
  list.  So this stuff is never used.

  o Always make TSC available via get_cycles() when TSC is present

Jozsef Kadlecsik:
  o [NETFILTER]: Use list macros instead of reimplementation

  ip_ct_selective_cleanup() 

Keith Owens:
  o ia64: fix offsets.h generation bootstrap problem
  o ia64: mca_asm.h documentation fixes
  o ia64: Trivial fixes for correct field type in formats.  prfunc_t does
  not include attribute format so gcc does not pick these up
  automatically. 
  o ia64: salinfo.c cleanup and race removal
  o ia64: print header from INIT records
  o ia64: fix comment typo (sal.h)
  o ia64: Clean up kernel salinfo state checking

  and/or the prom to decode the oem data sections of SAL records. 
  o ia64: Update PAL_MC_ERROR_INFO structures for SDM 2.1
  o ia64: sync salinfo.c with 2.6 (suser -> capable, use standard macros)

Kochi Takayoshi:
  o ia64: initialize bootmem later, since acpi_table_init() doesn't need it
  o ia64: don't access per-CPU data of off-line CPUs

Krishna Kumar:
  o [IPV6]: Fix ref count bug in MLDv2, test idec->dead instead of IFF_UP

Linus Torvalds:

  during applying the default ACL (eg. from ENOSPC) 
  o [XFS] Fix a compiler warning, sync_fs returns a value
  o [XFS] Fix a race condition in async pagebuf IO completion, by moving
  blk queue manipulation down into pagebuf.  Fix some busted comments in
  page_buf.h, use a more descriptive name for __pagebuf_iorequest 
  o [XFS] Use the rounded down size value for all growfs calculations, else
  the last AG can be updated incorrectly 
  o [XFS] Fix a harmless typo - we were using a pagebuf flag not a bmap
  flag here; fortunately they have the same value (2) 
  o [XFS] Tweak last dabuf fix, suggested by Steve, no longer uses
  bitfields but uchars instead 
  o [XFS] Fix a case where we could issue an unwritten extent buffer for IO
  without it being locked - an instant BUG trigger in the block layer 
  o [XFS] Alternate, cleaner fix for the ENOSPC/ACL lookup problem
  o [XFS] Automatically set logbsize for larger stripe units
  o [XFS] Add inode64 mount option; fix case where growfs can push 32 bit
  inodes into 64 bit space accidentally - both changes originally from IRIX 
  o [XFS] Fix races between O_DIRECT and fcntl with F_SETFL flag on the XFS
  IO path 
  o [XFS] DMAPI changes required by direct IO/fcntl setfl interaction races
  o [XFS] Separate the big filesystems macro out into separate big inums
  and blknos macros.  Also fix the check for too-large filesystems in the
  process 
  o [XFS] Undo last mod, checked in against wrong bug number with wrong
  change message 
  o [XFS] Separate the big filesystems macro out into separate big inums
  and blknos macros; fix the check for too-large filesystems in the process 
  o [XFS] Implement several additional inode flags - immutable,
  append-only, etc; contributed by Ethan Benson 
  o [XFS] Some tweaks to the additional inode flags, suggested by Ethan
  o [XFS] Accidentally switched some debug code off, reenable it
  o [XFS] Allow syncing the types header up more easily with userspace
  o [XFS] Make debug code _exactly_ how it used to be to save on tree merging
  o [XFS] Change writepage code so that we mark a page uptodate if all of
  its buffers are uptodate, and we are not doing a partial page write 
  o [XFS] Remove xfs_attr_fetch.c - the one routine was a copy of another,
  so instead of fixing a bug in two places I merged the two routines 
  o [XFS] Use the same name for a function here as in the 2.5/2.6 tree
  o [XFS] Use xfs_dev_t size rather than dev_t size in xfs_attr_fork
  initialization 
  o [XFS] Rename _inode_init_once to __inode_init_once to follow the kernel
  naming convention a bit more closely 
  o [XFS] Fix a broken interaction between a buffered read into an
  unwritten extent and a direct write 
  o [XFS] Clean up inode revalidation code slightly
  o [XFS] Fix up pointers in diagnostics, print using %p not %x for 64 bit
  platforms

  XFS tracing option for the other XFS trace code to use too (once fixed) 
  o [XFS] Fix compiler warning after change to xfs_ioctl interface
  o [XFS] Use an xfs_ino_t to hold the result of inode extraction from a
  handle, not a possibly 32-bit number 
  o [XFS] final round of code cleanup, now using 3-clause-bsd in these headers
  o [XFS] Fix inode btree lookup code precision problem with large
  allocation groups 
  o [XFS] Add some IO path tracing, move inval_cached_pages to a better
  home to help 
  o [XFS] Fix ktrace code - dont build unilaterally, and do earlier init
  for pagebuf use 
  o [XFS] Fix log tracing code so it is independent of DEBUG like other traces
  o [XFS] Add back xfsidbg tracing code, remove ktrace<->debug dependency
  o [XFS] Fix build fallout from reordering xfsidbg headers for tracing fixes
  o [XFS] Rename the vnode tracing macro to be consistent with the other
  trace code 
  o [XFS] Enable tracing in the quota code if requested
  o [XFS] Fix exports for tracing symbol access in idbg code
  o [XFS] When tracing extended attribute calls, only access the buffer
  when it exists

  locking fix; this would manifest itself as a second unlock_page call on
  an already unlocked page 
  o [XFS] Fix a deadlock while writing when low on free space
  o [XFS] Remove some spurious 2.4/2.6 differences in support code
  o [XFS] Fix sign on a pagebuf error variable, backport from 2.6 tree
  o [XFS] Fix an infinite writepage loop under a combination of low free
  space, and racing write/unlink calls to the same file 
  o [XFS] Enable pagebuf lock tracking via debug
  o [XFS] Backport a couple of debugging changes from the 2.6 code base
  o [XFS] Backport minor 2.6 changes to the iomap interface to keep code
  more in sync 
  o [XFS] Backport an unmerged bug fix from the 2.6 code base - if
  probe_unmapped_page fails while walking down the unmapped page list, do
  not attempt to probe the last page as well just return 
  o [XFS] Backport an unmerged bug fix from the 2.6 code base - only submit
  a convert_page page for IO if startio is set 
  o [XFS] Backport some trivial changes from the 2.6 code base - page
  uptodate flag macro name changes 
  o [XFS] Move Linux-version specific code out of xfs_iomap.c so that it
  can become part of the XFS core code 
  o [XFS] Seperate the NFS reference cache code out from xfs_rw.c to
  simplify management of different kernel versions

  o [XFS] Fix build fallout from refcache reorganisation
  o [XFS] Move the stack trace wrapper into a kernel-version-specific location
  o [XFS] Switch from using dev_t to xfs_buftarg_t for representing the
  devices underneath XFS 
  o [XFS] Merge find_next_zero_bit casting fixes back from 2.6 code
  o [XFS] Use iomap abstraction consistently
  o [XFS] Abstract sendfile operation out, supporting multiple kernels more
  easily 
  o [XFS] Use xfs_statfs type to statfs operation, to support multiple
  kernels more easily

  o [XFS] Abstract out the current_time interface use from quota to support
  multiple kernel versions 
  o [XFS] Fix some incorrect debug code after buftarg changes
  o [XFS] Use a kmem shaking interface for 2.4 which is much more like the
  2.6 one 
  o [XFS] Convert to revised kmem shake interface
  o [XFS] Update the way we hook into the generic direct IO code so we
  share more code.  This means we no longer need to dup remove_suid within
  xfs_write_clear_setuid 
  o [XFS] Add the noikeep mount option, make ikeep the default for now
  o [XFS] Use vnode timespec modifiers for atime/mtime/ctime, keeps last
  code hunk in sync

Stephen Lord:
  o [XFS] do not put 0x in front of a decimal number, its confusing
  o [XFS] fix up xfs_lowbit's use of ffs
  o [XFS] fix build for gcc 3.2
  o [XFS] Make xfs_ichgtime call mark_inode_dirty_sync instead of
  mark_inode_dirty makes the just the inode look dirty, and not the inode
  and the data. 
  o [XFS] remove an impossible code path from mkdir and link paths, spotted
  by Al Viro. 
  o [XFS] Switch pagebuf hashing to be based on the block_device address
  rather than the dev_t. Should give better distribution. 
  o [XFS] remove dead function xfs_trans_iput
  o [XFS] Close some holes in the metadata flush logic used during unmount,
  make sure we have no pending I/O completion calls for metadata, and that
  we only keep hold of metadata buffers for I/O completion if we want
  to. Still not perfect, but better than it was. 
  o [XFS] When calculating the number of pages to probe for an unwritten
  extent, use the size of the extent, not the page count of the pagebuf
  which is initialized to zero. 
  o [XFS] Rework how xfs and the linux generic I/O code interoperate again
  to deal with deadlock issues between the i_sem and i_alloc_sem and the
  xfs IO lock. 
  o [XFS] move unwritten extent conversion for O_DIRECT into the write
  thread and out of the I/O completion threads. This scales better. 
  o [XFS] Code cleanup
  o [XFS] small cleanup
  o [XFS] fix the previous change which compiled by fluke, the conditional
  use of the i_alloc_sem was wrong. No actual change in the generated code
  for 2.4.22, there will be for older kernels though. 
  o [XFS] fix up error unlock paths in xfs_write
  o [XFS] Implement deletion of inode clusters in XFS
  o [XFS] cleanup uio use some more
  o [XFS] remove FINVIS from xfs, instead use a seperate file ops vector
  for files which are opened for invisible I/O.
