Hi,
      I am using SMP machine with 256 MB Ram. I am using kmap function in
readpage function
      it is returning NULL value.

      Here is some log
      highmem_start_page = c13bf8ac
      page address is =    c132a194
      readpage:kmap address is NULL=0

      here kmap is returning page->virtual which value is NULL
      i checked pp->virtual is NULL.
      When i  read some files or write something to the file it is giving
      "bad address"
      when i am going through symlink, system is getting panic..

      but same code is working fine in uni-processor.

      i am using 2.4.21-4.EL kernel ..

      please help me..

      i am not getting what to do..?


      code location is
