+Simple work-around for running the 64-bit Adobe Flash plug-in version 10
+on Athlon64 processors without support for the lahf instruction.
+
+Compile with:
+cc -fPIC -shared -nostdlib -lc -oflashplugin-lahf-fix.so flashplugin-lahf-fix.c
+Then place the .so file in the plug-in directory (e.g. $HOME/.mozilla/plugins)
+or use LD_PRELOAD to force Firefox to load the library.

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.  Line
+# up the first '|' above the ':' following the base package name, and the '|'
+# on the right side marks the last column you can put a character in.  You must
+# make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':'.

+flashplugin-lahf-fix: This fix basically traps interrupts to see if it's due to lahf
+flashplugin-lahf-fix: missing, then either returns OK or let's the interrupt continue for
+flashplugin-lahf-fix: further processing.
