The polling loops in pread() and pwrite() can easily become infinite loops and hang the machine. Merge the IRQ check into host buffer wait loop and add polling limit. Also place a limit on polling for 53C80 registers accessibility. [Use NCR5380_poll_politely2() for register polling. Rely on polling for gated IRQ rather than polling for phase error, like the algorithm in the 53c400 datasheet. Move DTC436 workarounds into a separate patch. Factor-out common code as wait_for_53c80_access(). Rework the residual calculations. -- F.T.] Signed-off-by: Ondrej Zary <linux@rainbow-software.org> Signed-off-by: Finn Thain <fthain@telegraphics.com.au> Tested-by: Ondrej Zary <linux@rainbow-software.org> Signed-off-by: Martin K.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
