Global variable declarations must match the definitions in section attributes
as the compiler is at liberty to vary the method it uses to access a variable,
depending on the section it is in.When building the FRV arch, I now see:
drivers/built-in.o: In function `pci_apply_final_quirks':
drivers/pci/quirks.c:2606: relocation truncated to fit: R_FRV_GPREL12 against symbol `pci_dfl_cache_line_size' defined in .devinit.data section in drivers/built-in.o
drivers/pci/quirks.c:2623: relocation truncated to fit: R_FRV_GPREL12 against symbol `pci_dfl_cache_line_size' defined in .devinit.data section in drivers/built-in.o
drivers/pci/quirks.c:2630: relocation truncated to fit: R_FRV_GPREL12 against symbol `pci_dfl_cache_line_size' defined in .devinit.data section in drivers/built-in.obecause the declaration of pci_dfl_cache_line_size in linux/pci.h does not
match the definition in drivers/pci/pci.c.Signed-off-by: David Howells

In recent months, two different network projects erroneously
strayed down the rw_lock path. Update the Documentation
based upon comments by Eric Dumazet and Paul E. McKenney in
those threads.Further updates await somebody else with more expertise.
Changes:
- Merged with extensive content by Stephen Hemminger.
- Fix one of the comments by Linus Torvalds.Signed-off-by: William.Allen.Simpson@gmail.com

Microblaze version 7.20.d is the first MB version which can be run
on MMU linux. Please do not used previous version because they contain
HW bug.
Based on WB support was necessary to redesign whole cache design.
Microblaze versions from 7.20.a don't need to disable IRQ and cache
before working with them that's why there are special structures for it.Signed-off-by: Michal Simek

We need to continue with next microblaze PVR version that's why
I have to remove that ancient version. These version strings not match
any versions. From Microblaze v5.00.a is possible to use this style.
I believe that none use ancients versions. If yes they will be just
labeled as unknown version.Signed-off-by: Michal Simek

This was intended to allow manual override of CPU settings copied automatically
to Kconfig.auto, however it's problematic for several reasons, but mostly:* If the defconfig doesn't have ALLOW_EDIT_AUTO=y, then it's impossible for
that defconfig to iverride the values in the kernel source tree. This leads
to very strange errors where the kernel is compiled with the wrong CPUFLAGS.Next patch in the series will back out the default in Kconfig.auto to baseline
settings, so a kernel built with no default values will at least boot on any
hardware, just not make use of additional CPU features.Signed-off-by: John Williams

Two version are generated.
linux.bin.ub which is created from linux.bin file
and
simpleImage..ub which is created from stripped simpleImage. fileLoad address and entry point is for microblaze first instruction
which is CONFIG_KERNEL_BASE_ADDR variable.There is possible for simpleImage format parse _start symbol too.
simpleImage. is still stripped elf file
