Thank you for your work about the several patches.

At present, I finished all lock_user_struct() and unlock_user_struct()
in "linux-user/syscall.c". For me, after this patch, they are all OK.

But for all lock/unlock in "linux-user/syscall.c", for me, I am doubting
several areas, but I did not send patch for them:

 - I need check them carefully again to be sure they are really issue:

   Read the related code again and again, if I really treat it as an
   issue, I shall make related patch (and pass compiling, at least).

 - I have no enough time resources on it:

   In week end, I have to spend some time resource on my son (check his
   homework, play with him). I also need spend time resources on Linux
   kernel and gcc/binutils.

   In week day, I may work overtime sometimes, also I need spend 4 hours
   on subway between my home and office per day (come and go).

 - So it is really necessary for me to make a schedule (the tasks/steps,
   the time point, and the risks), and also need consider about:

   How to use the time resources efficiently: e.g. fully use the time
   resources on the subway between home and office, in work day; fully
   use the time resources on holidays (e.g. Chinese Spring Festival).

   How to fully use the human resources: e.g. try my best to always keep
   well communication with all related open source members (which will
   give much valuable help for the related tasks).

Welcome any members' ideas, suggestions, and completions, also welcome
any members to help check "linux-user/syscall.c" (it will save my time
resource: now for qemu, my highest priority task is for tile qemu).

Thanks.
