What code is related to the writable page?
In xen 3.0.4-1 source, where is the *unhook/rehook page table
implementation* which is important things in ''writable page table mode''.?
I can''t find it.

Xeno Linux never pins L1 tables ?
hi,
I''m developing my own 32-bit (no PAE) paravirtualized kernel for xen with
Mini-OS as a starting point. I am currently working on process page table
support (equivalent of arch/i386/mm/pgtable-xen.c) and mostly following
Linux for the moment. I noticed that linux-2.6.18-xen never pins an L1 table
(a pte), yet __pgd_pin() walks the page directory and gives up write access
on the kernel

[PATCH] fish: reset the console on ^Z RHBZ#1213844
Patch registers SIGTSTP hook where it sends reset terminal color
control sequence using write and fsync.
Handler is installed only if signal is not being ignored.
Patch uses rl_free_line_state and rl_cleanup_after_signal to unhook
readline from terminal, then it calls original TSTP handler using
approach in URL below and again hooks readline using
rl_reset_after_signal.
Handling is based on code

[PATCH] turn off writable page tables
At OLS I gave a talk on some of the Xen scalability inhibitors, and one
of these was writable page tables. We went over why the feature does
not scale, but just as important, we found that the uniprocessor case
does not provide any advantage either. These tests were done on x86_64,
so I wanted to run the 1-way test on 32 bit to show the same problem.
So, I have run with writable PTs and
