      [PATCH] Create kallsyms_lookup_size_offset() · ffc50891
      Franck Bui-Huu authored 
      Some uses of kallsyms_lookup() do not need to find out the name of a symbol
and its module's name it belongs.  This is specially true in arch specific
code, which needs to unwind the stack to show the back trace during oops
(mips is an example).  In this specific case, we just need to retreive the
function's size and the offset of the active intruction inside it.

Adds a new entry "kallsyms_lookup_size_offset()" This new entry does
exactly the same as kallsyms_lookup() but does not require any buffers to
store any names.

It returns 0 if it fails otherwise 1.

      [PATCH] FRV: Permit large kmalloc allocations [try #2] · 339b0c08
      David Howells authored 
      Permit kmalloc() to make allocations of up to 32MB if so configured.  This
may be useful under NOMMU conditions where vmalloc() can't do this.

      [PATCH] VFS: Make filldir_t and struct kstat deal in 64-bit inode numbers · afefdbb2
      David Howells authored 
      These patches make the kernel pass 64-bit inode numbers internally when
communicating to userspace, even on a 32-bit system.  They are required
because some filesystems have intrinsic 64-bit inode numbers: NFS3+ and XFS
for example.  The 64-bit inode numbers are then propagated to userspace
automatically where the arch supports it.

Problems have been seen with userspace (eg: ld.so) using the 64-bit inode
number returned by stat64() or getdents64() to differentiate files, and
failing because the 64-bit inode number space was compressed to 32-bits, and
so overlaps occur.

This patch:

Make filldir_t take a 64-bit inode number and struct kstat carry a 64-bit
inode number so that 64-bit inode numbers can be passed back to userspace.

The stat functions then returns the full 64-bit inode number where
available and where possible.  If it is not possible to represent the inode
number supplied by the filesystem in the field provided by userspace, then
error EOVERFLOW will be issued.

Similarly, the getdents/readdir functions now pass the full 64-bit inode
number to userspace where possible, returning EOVERFLOW instead when a
directory entry is encountered that can't be properly represented.

Note that this means that some inodes will not be stat'able on a 32-bit
system with old libraries where they were before - but it does mean that
there will be no ambiguity over what a 32-bit inode number refers to.

Note similarly that directory scans may be cut short with an error on a
32-bit system with old libraries where the scan would work before for the
same reasons.

It is judged unlikely that this situation will occur because modern glibc
uses 64-bit capable versions of stat and getdents class functions
exclusively, and that older systems are unlikely to encounter
unrepresentable inode numbers anyway.

      [PATCH] hp100: fix conditional compilation mess · 7525d4bf
      Jeff Garzik authored 
      The previous hp100 changeset attempted to kill warnings, but was only
tested on !CONFIG_ISA platforms.  The correct conditional compilation
setup involves tested CONFIG_ISA rather than just MODULE.

Fixes link on CONFIG_ISA platforms (i386) in current -git.

      [PATCH] revert "insert IOAPIC(s) and Local APIC into resource map" · 0e4a523f
      Andrew Morton authored 
      Commit 54dbc0c9 is causing various
people's machines to fail to map PCI resources.

Revert it in preparation for addressing the show-APICs-in-/proc/iomem
requirement in a different manner.
