error with “pmem.c” compiling linux source code for android
I am compiling linux source code for android emulator. When i execute make command(for building and cross-compiling the linux source) i get the following error "pmem.c" file.
root@ubuntu:~# cd common
SYMLINK include/asm -> include/asm-x86
drivers/misc/pmem.c:441: error: conflicting types for ‘phys_mem_access_prot’
/home/preetam/common/arch/x86/include/asm/pgtable.h:383: note: previous declaration of ‘phys_mem_access_prot’ was here
drivers/misc/pmem.c: In function ‘flush_pmem_file’:
drivers/misc/pmem.c:805: error: implicit declaration of function ‘dmac_flush_range’
drivers/misc/pmem.c: In function ‘pmem_setup’:
drivers/misc/pmem.c:1265: error: implicit declaration of function ‘ioremap_cached’

make: *** [drivers/misc/pmem.o] Error 1
make: *** [drivers/misc] Error 2
make: *** [drivers] Error 2
how to resolve this error. It seems that there may some problems in the "pmem.c" file and i'll have to choose different git repository. but that would be a very complex thing, as now i have already done most of the things till here. I might have to see correct version of this file. please someone tell what should i do?
how to solve this errors.
The way to sort this stuff is to grab the first essential error, and google it. In this case
pmem.c:441: error: conflicting types for ‘phys_mem_access_prot’
Which usually yields an answer, in this case
