226eb1ef52 Blackfin arch: cleanup arch/blackfin/kernel/traps.c handling code.
- move the CONFIG_KGDB into one block, for easier reading
 - remove printk from printk_address, and pass around buffers. Also
   print out the labels when decoding CPLB errors, so you know exactly
   where the error was.
 - Do not use fixed addresses, becuase people do not know where they come from.
 - Turn the printing level down on the dump, so if you don't want,
   only the signal prints out - just like on other archs. If a kernel/interrupt
   crashes, it should dump everything all the time

2a6f4e4983 ehea: add kexec support
eHEA resources that are allocated via H_CALLs have a unique identifier each.
These identifiers are necessary to free the resources. A reboot notifier
is used to free all eHEA resources before the indentifiers get lost, i.e
before kexec starts a new kernel.

140a748028 e1000e: Re-enable SECRC - crc stripping
This workaround code performed software stripping instead of the
hardware which can do it much faster. None of the e1000e target
hardware has issues with this feature and should work fine. This
gives us some performance back on receive, and removes some
kludging stripping the 4 bytes.

df762464ad e1000e: Fix PBA calculation for jumbo frame packets
Upon inspection the rx FIFO size calculation code was found to have
2 significant flaws: A superfluous minus sign resulting in the
wrong size to be used for jumbo frames on 82573 and ich9, as well
as that this code rewrote the read-only adapter->pba variable
resulting in different values at each run.

Without this patch jumbo's will work but performance will be
awkward since the TX size is not adequate for two whole frames.

47f44e40a3 e1000e: Fix jumbo frame receive code.
Fix allocation and freeing of jumbo frames where several bugs
were recently introduced by cleanups after we forked this code
from e1000. This moves ps_pages to buffer_info where it really
belongs and makes it a dynamically allocated array. The penalty
is not that high since it's allocated outside of the buffer_info
struct anyway.

Without this patch all jumbo frames are completely broken and the
driver panics.

 - stop calling write_lock_irq/write_unlock_irq which can turn modify

 - don't calling mmput when handing exceptions - since this might_sleep,
   which does a rti, and leaves us in kernel space (irq15, rather

69243f9125 x86: Dump filtering supports x86_64 sparsemem
This patch adds the symbol "init_level4_pgt" to the vmcoreinfo data so
that makedumpfile (dump filtering command) supports x86_64 sparsemem 
kernel of linux-2.6.24.

makedumpfile creates a small dumpfile by excluding unnecessary pages for
the analysis. It checks attributes in page structures and distinguishes
necessary pages and unnecessary ones. To check them, makedumpfile gets
the vmcoreinfo data which has the minimum debugging information only for
dump filtering.

For older x86_64 kernel (linux-2.6.23 or before), makedumpfile translates
the virtual address of page structure into physical address by subtracting
PAGE_OFFSET from virtual address, but this translation isn't effective for
linux-2.6.24 sparsemem kernel, because its page structures are in virtual
memmap area. makedumpfile should translate their virtual address by 4-levels
paging and it needs the symbol "init_level4_pgt".

bd53147db8 x86: Fix boot protocol KEEP_SEGMENTS check.
The kernel only ever supports 1 version of the boot protocol
so there is no need to check the boot protocol revision to
see if a feature is supported.

Both x86 and x86_64 support the same boot protocol so we need
to implement the KEEP_SEGMENTS on x86_64 as well.  It isn't
just paravirt bootloaders that could use this functionality.

Secondly, the actual definition has this as a SHARED_ALIGNED, so the
