This patch removes the assumption of the bootgraph.pl script that the
timing information reported by PRINTK_TIME will contain at least one
entry with a time of less than 100 seconds.

Not all boards correctly reset the system timer and in many cases the
inital times reported by PRINTK_TIME is high. When this occurs the
bootchart.pl script fails to give any useful output.

This patch sets the $firsttime variable to the largest value expected
by PRINTK_TIME

Done via coccinelle scripts like:

During converting per-cpu ticker to genirq layer some
IRQ initialization code was removed by commit
2cf95304 ("sparc32,leon:
per-cpu ticker use genirq per-cpu handler").

This patch reintroduces the code at the same place it was
removed from. IRQ12 - IRQ14 will crash on LEON SMP without
this patch because it will run the SUN4M IRQ trap handler.

Three new IPIs were introduced by commit
ecbc42b7 ("sparc32, sun4m:
Implemented SMP IPIs support for SUN4M machines"), the
old handler was already prepared for IPIs but handled only
IRQ14 and IRQ13, this patch adds support for the new IPI at
IRQ12.

The IPI trap handler looks at the mask rather than the
pending IRQ/IPI, this bug may have masked the problem
above, introduced by the same commit.

Unconditionally changing the address limit to USER_DS and not restoring
it to its old value in the error path is wrong because it prevents us
using kernel memory on repeated calls to this function.  This, in fact,
breaks the fallback of hard coded paths to the init program from being
ever successful if the first candidate fails to load.

With this patch applied switching to USER_DS is delayed until the point
of no return is reached which makes it possible to have a multi-arch
rootfs with one arch specific init binary for each of the (hard coded)
probed paths.

Since the address limit is already set to USER_DS when start_thread()
will be invoked, this redundancy can be safely removed.

When using 64K pages with a separate cpio rootfs, U-Boot will align
the rootfs on a 4K page boundary. When the memory is reserved, and
subsequent early memblock_alloc is called, it will allocate memory
between the 64K page alignment and reserved memory. When the reserved
memory is subsequently freed, it is done so by pages, causing the
early memblock_alloc requests to be re-used, which in my case, caused
the device-tree to be clobbered.

This patch forces the reserved memory for initrd to be kernel page
aligned, and will move the device tree if it overlaps with the range
extension of initrd. This patch will also consolidate the identical
function free_initrd_mem() from mm/init_32.c, init_64.c to mm/mem.c,
and adds the same range extension when freeing initrd. free_initrd_mem()
is also moved to the __init section.

This tries to make the 'struct inode' accesses denser in the data cache
by moving a commonly accessed field (i_security) closer to other fields
that are accessed often.

It also makes 'i_state' just an 'unsigned int' rather than 'unsigned
long', since we only use a few bits of that field, and moves it next to
the existing 'i_flags' so that we potentially get better structure
layout (although depending on config options, i_flags may already have
packed in the same word as i_lock, so this improves packing only for the
case of spinlock debugging)

Out 'struct inode' is still way too big, and we should probably move
some other fields around too (the acl fields in particular) for better
data cache access density.  Other fields (like the inode hash) are
likely to be entirely irrelevant under most loads.

This is a rather hot function that is called with a potentially NULL
"struct common_audit_data" pointer argument.  And in that case it has to
provide and initialize its own dummy common_audit_data structure.

However, all the _common_ cases already pass it a real audit-data
structure, so that uncommon NULL case not only creates a silly run-time
test, more importantly it causes that function to have a big stack frame
for the dummy variable that isn't even used in the common case!

So get rid of that stupid run-time behavior, and make the (few)
functions that currently call with a NULL pointer just call a new helper
function instead (naturally called inode_has_perm_noapd(), since it has
no adp argument).

This makes the run-time test be a static code generation issue instead,
and allows for a much denser stack since none of the common callers need
the dummy structure.  And a denser stack not only means less stack space
usage, it means better cache behavior.  So we have a win-win-win from
this simplification: less code executed, smaller stack footprint, and
better cache behavior.
