• 6672f76a5   kdump/kexec: calculate note size at compile time ... Browse Code »

  Currently the size of the per-cpu region reserved to save crash notes is
  set by the per-architecture value MAX_NOTE_BYTES. Which in turn is
  currently set to 1024 on all supported architectures.

  While testing ia64 I recently discovered that this value is in fact too
  small. The particular setup I was using actually needs 1172 bytes. This
  lead to very tedious failure mode where the tail of one elf note would
  overwrite the head of another if they ended up being alocated sequentially
  by kmalloc, which was often the case.

  It seems to me that a far better approach is to caclculate the size that
  the area needs to be. This patch does just that.

  If a simpler stop-gap patch for ia64 to be squeezed into 2.6.21(.X) is
  needed then this should be as easy as making MAX_NOTE_BYTES larger in
  arch/asm-ia64/kexec.h. Perhaps 2048 would be a good choice. However, I
  think that the approach in this patch is a much more robust idea.

• 297632544   [IA64] kexec: declare ia64_mca_pal_base in mca.h rather than kexec.h ... Browse Code »

  * Kexec adds some code to arch/ia64/kernel/smp.c which needs ia64_mca_pal_base,
  so the kexec patch (actually the kdump patch) declares this
  per-cpu variable in include/asm-ia64/kexec.h.

  * ia64_mca_pal_base is defined in arch/ia64/kernel/mca.c, so it
  seems to me that it would make a lot more sense to declare it in
  include/asm-ia64/mca.h.

• c5a69d57e   Storage class should be before const qualifier ... Browse Code »

  The C99 specification states in section 6.11.5:

  The placement of a storage-class specifier other than at the
  beginning of the declaration specifiers in a declaration is an
  obsolescent feature.
