[Uri S.] infradead.org has been added to our "trusted" domains list, hope it'll solve the problem.

[Uri S.] I'm attaching to this email an archive of patches.
(!) Note: Regarding the GPIO implementation that is currently in Mercurial tree, there are logical errors embedded in it, which may cause system (SMS chip-set) failure.
(!) Michael - Please modify the new sms-cards.c (Tiger related) code to reflect the wanted I/O behavior after the attached patches will be committed.
I'll also email the patches one by one to linux-media at vger.kernel.org, in clear text, so the robot will process them.

[Uri S.] I created ("clone") the tree locally, but to have an external access to it will demand very long work with our IT department. It'll be much simpler to create an account at Linuxtv.org.

[Uri S.] Please note that my selfish convenient points to the Mercurial tree option, with it I can mirror any commit to the Siano's SVN repository with a matching commit to the Mercurial repository, and use the hg, hgview, hgtk and other tools to monitor with ease the changes history (and even write the SVN commit's number in the Mercurial and vice versa). But again, I can manage everything (with auxiliary spreadsheet, and a little more effort) using the commits-by-emails method.
Anyway, I'll take your lead regarding it, please let me know which method should be used.
