[SPARC]: change if() BUG(); to BUG_ON in iommu.c · 1ae61388

Eric Sesterhenn authored Jan 17, 2006

this patch changes if() BUG(); constructs
in iommu.c to BUG_ON(); so it gets save
to define BUG() and BUG_ON() to nullstatements.

[SPARC64]: Eliminate race condition reading Hummingbird STICK register · 9eb3394b

Richard Mortimer authored Jan 17, 2006

Ensure a consistent value is read from the STICK register by ensuring
that both high and low are read without high changing due to a roll
over of the low register.

Various Debian/SPARC users (myself include) have noticed problems with
Hummingbird based systems. The symptoms are that the system time is
seen to jump forward 3 days, 6 hours, 11 minutes give or take a few
seconds. In many cases the system then hangs some time afterwards.

I've spotted a race condition in the code to read the STICK register.
I could not work out why 3d, 6h, 11m is important but guess that it is
due to the 2^32 jump of STICK (forwards on one read and then the next
read will seem to be backwards) during a timer interrupt. I'm guessing
that a change of -2^32 will get converted to a large unsigned
increment after the arithmetic manipulation between STICK,
nanoseconds, jiffies etc.

I did a test where I modified __hbird_read_stick to artificially
inject rollover faults forcefully every few seconds. With this I saw
the clock jump over 6 times in 12 hours compared to once every month
or so.

[PATCH] x86_64: Fix VSMP build · 2ddb55f0

Ravikiran G Thirumalai authored Jan 17, 2006

Patch fixes a build problem with CONFIG_X86_VSMP. The vSMP bits probably

gathered some fuzz on its way to mainline, and safe_halt() which was outside
the #endif (CONFIG_X86_VSMP) somehow got inside the !CONFIG_X86_VSMP condition,
hence being undefined and breaking CONFIG_X86_VSMP builds. Patch takes
safe_halt() and halt() macros out of the #endif

hot-add usable on x86-64 machines.  Also, fixup the nefarious
conditional locking and exports pointed out by Andi.
