      [IA64] Ensure cpu0 can access per-cpu variables in early boot code · 10617bbe
      由 Tony Luck 提交于 
      ia64 handles per-cpu variables a litle differently from other architectures
in that it maps the physical memory allocated for each cpu at a constant
virtual address (0xffffffffffff0000). This mapping is not enabled until
the architecture specific cpu_init() function is run, which causes problems
since some generic code is run before this point. In particular when
CONFIG_PRINTK_TIME is enabled, the boot cpu will trap on the access to
per-cpu memory at the first printk() call so the boot will fail without
the kernel printing anything to the console.

Fix this by allocating percpu memory for cpu0 in the kernel data section
and doing all initialization to enable percpu access in head.S before
calling any generic code.

Other cpus must take care not to access per-cpu variables too early, but
their code path from start_secondary() to cpu_init() is all in arch/ia64

      x86: Restore proper vector locking during cpu hotplug · d388e5fd
      由 Eric W. Biederman 提交于 
      Having cpu_online_map change during assign_irq_vector can result
in some really nasty and weird things happening.  The one that
bit me last time was accessing non existent per cpu memory for non
existent cpus.

This locking was removed in a sloppy x86_64 and x86_32 merge patch.

Guys can we please try and avoid subtly breaking x86 when we are
merging files together?

      powerpc: Do not ignore arch/powerpc/include · 0afd2ac9
      由 Junio C Hamano 提交于 
      Back when .gitignore file was added to arch/powerpc/ in 06f2138e ([POWERPC]
Add files build to .gitignore, 2006-11-26), there indeed was nothing
tracked in the ignored hierarchy and ignoring everything made sense.  But
we have very many tracked files there these days, and having a higher
level .gitignore that ignores everything is asking for future troubles..

This should have been part of b8b572e1 (powerpc: Move include files to
arch/powerpc/include/asm, 2008-08-01).

      powerpc/mm: Fix attribute confusion with htab_bolt_mapping() · bc033b63
      由 Benjamin Herrenschmidt 提交于 
      The function htab_bolt_mapping() is used to create permanent
mappings in the MMU hash table, for example, in order to create
the linear mapping of vmemmap.  It's also used by early boot
ioremap (before mem_init_done).

However, the way ioremap uses it is incorrect as it passes it the
protection flags in the "linux PTE" form while htab_bolt_mapping()
expects them in the hash table format.  This is made more confusing by
the fact that some of those flags are actually in the same position in
both cases.

This fixes it all by making htab_bolt_mapping() take normal linux
protection flags instead, and use a little helper to convert them to
htab flags. Callers can now use the usual PAGE_* definitions safely.

      powerpc/pci: Don't keep ISA memory hole resources in the tree · 8db13a0e
      由 Benjamin Herrenschmidt 提交于 
      When we have an ISA memory hole (ie, a PCI window that allows us to
generate PCI memory cycles at low PCI address) mixed with other
resources using a different CPU <=> PCI mapping, we must not keep
the ISA hole in the bridge resource list.

If we do, things might start trying to allocate device resources
in there and will get the PCI addresses wrong.

This fixes it by arranging to remove the ISA memory hole resource in
this case.  This fixes various cases of PCMCIA breakage on PowerBooks
using the MPC106 "grackle" bridge.

      powerpc: Zero fill the return values of rtas argument buffer · b79998fc
      由 Nathan Fontenot 提交于 
      The kernel copy of the rtas args struct contains the return
value(s) for the specified rtas call.  These are copied back
to user space with the assumption that every value has been
set by the rtas call, which turns out to be not always true.
Thus userspace can see random values and think the call failed
when in fact it succeeded, but for some reason didn't set one
of the return values.

This fixes the problem by zeroing out the return value fields
of the rtas args struct before processing the rtas call.
