[MIPS] Hack for SB1 cache issues

2006-11-22T23:34:01+00:00

Removing flush_icache_page a while ago broke SB1 which was using an empty
flush_data_cache_page function.  This glues things well enough so a more
efficient but also more intrusive solution can be found later.

[MIPS] Fix aliasing bug in copy_to_user_page / copy_from_user_page

2006-10-21T22:17:35+00:00

The current implementation uses a sequence of a cacheflush and a copy.
This is racy in case of a multithreaded debuggee and renders GDB
virtually unusable.

Aside this fixes a performance hog rendering access to /proc/cmdline very
slow and resulting in a enough cache stalls for the 34K AP/SP programming
model to make the bare metal code on the non-Linux VPE miss RT deadlines.

The main part of this patch was originally written by Ralf Baechle;
Atushi Nemoto did the the debugging.

[MIPS] Fix iounmap argument to const volatile.

2006-10-19T16:55:14+00:00

With the existing prototype the following code:

    const void __iomem *io = ioremap();
    x = readb(io);
    iounmap(io);

did result in a warning.

Attack of "the the"s in arch

2006-10-03T20:21:02+00:00

The patch below corrects multiple occurances of "the the"
typos across several files, both in source comments and KConfig files.
There is no actual code changed, only text.  Note this only affects the /arch
directory, and I believe I could find many more elsewhere. :)
