2008-02-17[SPARC64] arch/sparc64/kernel/unaligned.c: Use time_* macrosS.Çağlar Onur
The functions time_before, time_before_eq, time_after, and time_after_eq are more robust for comparing jiffies against other values. So following patch implements usage of the time_after() macro, defined at linux/jiffies.h, which deals with wrapping correctly Signed-off-by: S.Çağlar Onur <caglar@pardus.org.tr> Signed-off-by: David S.

2007-05-08header cleaning: don't include smp_lock.h when not usedRandy Dunlap
Remove includes of <linux/smp_lock.h> where it is not used/needed. Suggested by Al Viro. Builds cleanly on x86_64, i386, alpha, ia64, powerpc, sparc, sparc64, and arm (all 59 defconfigs).

2006-12-10[SPARC64]: Unaligned accesses to userspace are hard errors.David S. Miller
Userspace is forbidden from making unaligned loads and stores. So if we get an unaligned trap due to a {get,put}_user(), signal a fault and run the exception handler. Signed-off-by: David S. Miller <davem@davemloft.net>

This makes things easier to track down, especially in modules. Signed-off-by: David S. Miller <davem@davemloft.net>

2005-09-28[SPARC64]: Fix fault handling in unaligned trap handler.David S. Miller
We were not calling kernel_mna_trap_fault() correctly. Instead of being fancy, just return 0 vs. -EFAULT from the assembler stubs, and handle that return value as appropriate. Create an "__retl_efault" stub for assembler exception table entries and use it where possible. Signed-off-by: David S. Miller <davem@davemloft.net>
2005-09-28[SPARC64]: Convert to use generic exception table support.David S. Miller
The funny "range" exception table entries we had were only used by the compat layer socketcall assembly, and it wasn't even needed there. For free we now get proper exception table sorting and fast binary searching. Signed-off-by: David S. Miller <davem@davemloft.net>
2005-09-28[SPARC64]: Fix bug in unaligned load endianness swappingDavid S. Miller
The in-memory value was being swapped, not the value we loaded into the register. Signed-off-by: David S. Miller <davem@davemloft.net>
2005-09-19[SPARC64]: Handle little-endian unaligned loads/stores correctly.David S. Miller
Because we use byte loads/stores to cons up the value in and out of registers, we can't expect the ASI endianness setting to take care of this for us. So do it by hand. This case is triggered by drivers/block/aoe/aoecmd.c in the ataid_complete() function where it goes: /* word 100: number lba48 sectors */ ssize = le64_to_cpup((__le64 *) &id[100<<1]); This &id[100<<1] address is 4 byte, rather than 8 byte aligned, thus triggering the unaligned exception.

2005-08-29[SPARC64]: Revamp Spitfire error trap handling.David S. Miller
Current uncorrectable error handling was poor enough that the processor could just loop taking the same trap over and over again. Fix things up so that we at least get a log message and perhaps even some register state. In the process, much consolidation became possible, particularly with the correctable error handler. Prefix assembler and C function names with "spitfire" to indicate that these are for Ultra-I/II/IIi/IIe only. More work is needed to make these routines robust and featureful to the level of the Ultra-III error handlers. Signed-off-by: David S. Miller <davem@davemloft.net>
2005-08-19[SPARC64]: Move kernel unaligned trap handlers into assembler file.David S. Miller
GCC 4.x really dislikes the games we are playing in unaligned.c, and the cleanest way to fix this is to move things into assembler. Noted by Al Viro. Signed-off-by: David S. Miller <davem@davemloft.net>
2005-04-16Linux-2.6.12-rc2Linus Torvalds
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
