migrate site/wiki docs over
Now that we've moved to GoB from code.google.com, import the docs.
This is a merge of three pages:

The svn logic was updated to git, and some more links added.

+# Linux Syscall Support (LSS)
+
+Every so often, projects need to directly embed Linux system calls instead of
+calling the implementations in the system runtime library.
+
+This project provides a header file that can be included into your application
+whenever you need to make direct system calls.
+
+## How to include linux\_syscall\_support.h in your project
+
+You can either copy the file into your project, or preferably, you can set up
+Git submodules to automatically pull from our source repository.
+
+## Projects that use LSS
+
+* [Chromium](https://www.chromium.org/)
+* [Breakpad](https://chromium.googlesource.com/breakpad/breakpad)
+* [Native Client](https://developer.chrome.com/native-client), in nacl\_bootstrap.c
+
+## How to get an LSS change committed
+
+### Review
+
+You get your change reviewed, you can upload it to
+[Rietveld](https://codereview.chromium.org)
+using `git cl upload` from
+[Chromium's depot-tools](http://dev.chromium.org/developers/how-tos/depottools).
+
+### Testing
+
+Unfortunately, LSS has no automated test suite.
+
+You can test LSS by patching it into Chromium, building Chromium, and running
+Chromium's tests.
+
+You can compile-test LSS by running:
+
+ gcc -Wall -Wextra -Wstrict-prototypes -c linux_syscall_support.h
+
+### Rolling into Chromium
+
+If you commit a change to LSS, please also commit a Chromium change to update
+`lss_revision` in
+[Chromium's DEPS](https://chromium.googlesource.com/chromium/src/+/master/DEPS)
+file.
+
+This ensures that the LSS change gets tested, so that people who commit later
+LSS changes don't run into problems with updating `lss_revision`.
