Hi Mulyadi/Spiro,
Can you please help me in partially enabling/disabling
optimizations, because I was consistently hitting at the below problem when
building the kernel after disabling the optimization
ERROR: "intel_gmbus_is_forced_bit" [drivers/gpu/drm/i915/i915.ko] undefined!
ERROR:
Thanks Prabhu.
So does this means that this ZONE_NORMAL limit of 896MB is because of 3:1
memory division?
If it is do then does this mean that if this ratio is changed then
ZONE_NORMAL limit will also be changed?
Regards,
Piyush

Hi,
Sometimes I get errors when compiling the latest staging tree -
recently it happened on the device drivers > mtd module due to
duplicate module_init functions and the build breaks. Do I need to
report them or its handled by some auto build system that takes care
of it.
Also I get errors on CO

Hi,
Regarding dmesg. I believe it will still show up in it. It can be
controlled by /proc/sys/kernel/printk settings. As per man 5 proc:
/proc/sys/kernel/printk
The four values in this file are console_loglevel, default_mes-

Whenever possible, yes...disable optimization -O option and -g in
gcc don't play nicely together according to my experience. The DWARF

I have one question in this context. Should we disable optimization when
building the kernel when we wish to enable kgdb or should we leave it
intact.
Thanks,

I have very basic some question's related to HighMem Memory Mapping:
1) Why can't we directly map memory in highmemory?
2) As documents at many places why is the limit of 896MB for ZONE_NORMAL?

Hi All,
I am new to linux kernel code and interested in filesystems and block I/O.
While going through the block read code ( in __bread function ) I found that
when we try to read the block ( __getblk ) we first check for the block
buffer page in page cache ( using __find_get_block function ) and
