c0c0a29379 vmalloc: add @align to vm_area_register_early()
Impact: allow larger alignment for early vmalloc area allocation

Some early vmalloc users might want larger alignment, for example, for
custom large page mapping.  Add @align to vm_area_register_early().
While at it, drop docbook comment on non-existent @size.

f0aa661790 vmalloc: implement vm_area_register_early()
Impact: allow multiple early vm areas

There are places where kernel VM area needs to be allocated before
vmalloc is initialized.  This is done by allocating static vm_struct,
initializing several fields and linking it to vmlist and later vmalloc
initialization picking up these from vmlist.  This is currently done
manually and if there's more than one such areas, there's no defined
way to arbitrate who gets which address.

This patch implements vm_area_register_early(), which takes vm_area
struct with flags and size initialized, assigns address to it and puts
it on the vmlist.  This way, multiple early vm areas can determine
which addresses they should use.  The only current user - alpha mm
init - is converted to use it.

1371be0f7c cpumask: Use cpu_*_mask accessors code: alpha
Impact: use new API, fix SMP bug.

Use the new accessors rather than frobbing bits directly.

This also removes the bug introduced in ee0c468b (alpha: compile
fixes) which had Alpha setting bits on an on-stack cpumask, not the
cpu_online_map.

945048ca36 alpha: fix the BUG() macro
The commit "alpha: teach the compiler that BUG doesn't return"
(ed6b9b97f4) moved the asm code into inline
function which takes __FILE__ and __LINE__ as arguments.  This violates
asm constrains there ("i" - an immediate operand with constant value), so
that compile may result in warning or error, depending on compiler
version.

Just adding an infinite loop to the BUG() is sufficient.

5f7dc5d750 alpha: fix RTC on marvel
Unlike other alphas, marvel doesn't have real PC-style CMOS clock hardware
- RTC accesses are emulated via PAL calls.  Unfortunately, for unknown
reason these calls work only on CPU #0.  So current implementation for
arbitrary CPU makes CMOS_READ/WRITE to be executed on CPU #0 via IPI.
However, for obvious reason this doesn't work with standard
get/set_rtc_time() functions, where a bunch of CMOS accesses is done with
disabled interrupts.

Solved by making the IPI calls for entire get/set_rtc_time() functions,
not for individual CMOS accesses.  Which is also a lot more effective
performance-wise.

The patch is largely based on the code from Jay Estabrook.
My changes:
- tweak asm-generic/rtc.h by adding a couple of #defines to
  avoid a massive code duplication in arch/alpha/include/asm/rtc.h;
- sys_marvel.c: fix get/set_rtc_time() return values (Jay's FIXMEs).

NOTE: this fixes *only* LIB_RTC drivers.  Legacy (CONFIG_RTC) driver
wont't work on marvel.  Actually I think that we should just disable
CONFIG_RTC on alpha (maybe in 2.6.30?), like most other arches - AFAIK,
all modern distributions use LIB_RTC anyway.

2f88d151cb alpha: nautilus - fix hang on boot
Recently introduced generic pci_common_swizzle() relies on bus->self
being NULL for the root PCI bus. But on nautilus bus->self points to
the host bridge device, which is necessary as we do a root bus sizing
on this system. As a result, pci_common_swizzle() loops infinitely.
This worked until 2.6.29-rc1 because the alpha-specific swizzle routine
checked for bus->parent == NULL (instead of bus->self).

Fixed by clearing bus->self after bus sizing is done.

70b66cbfd3 alpha: nautilus - fix compile failure with gcc-4.3
init_srm_irq() deals with irq's #16 and above, but size of irq_desc
array on nautilus and some other system types is 16. So gcc-4.3
complains that "array subscript is above array bounds", even though
this function is never called on those systems.

This adds a check for NR_IRQS <= 16, which effectively optimizes
init_srm_irq() code away on problematic platforms.

Thanks to Daniel Drake <dsd@gentoo.org> for detailed analysis
of the problem.

Not much point with gentle transition here: the struct irq_chip's
setaffinity method signature needs to change.

Fortunately, not widely used code, but hits a few architectures.

Note: In irq_select_affinity() I save a temporary in by mangling
irq_desc[irq].affinity directly.  Ingo, does this break anything?

98a79d6a50 cpumask: centralize cpu_online_map and cpu_possible_map
Impact: cleanup

Each SMP arch defines these themselves.  Move them to a central
location.

Twists:
1) Some archs (m32, parisc, s390) set possible_map to all 1, so we add a
   CONFIG_INIT_ALL_POSSIBLE for this rather than break them.

2) mips and sparc32 '#define cpu_possible_map phys_cpu_present_map'.
   Those archs simply have phys_cpu_present_map replaced everywhere.

3) Alpha defined cpu_possible_map to cpu_present_map; this is tricky
   so I just manipulate them both in sync.

4) IA64, cris and m32r have gratuitous 'extern cpumask_t cpu_possible_map'
   declarations.

b6dff3ec5e CRED: Separate task security context from task_struct
Separate the task security context from task_struct.  At this point, the
security data is temporarily embedded in the task_struct with two pointers
pointing to it.

Note that the Alpha arch is altered as it refers to (E)UID and (E)GID in
entry.S via asm-offsets.
