2010-11-18sh: Use GCC __builtin_prefetch() to implement prefetch().Giuseppe CAVALLARO1-2/+5
GCC's __builtin_prefetch() was introduced a long time ago, all supported GCC versions have it. So this patch is to use it for implementing the prefetch on SH2A and SH4. The current prefetch implementation is almost equivalent with __builtin_prefetch. The third parameter in the __builtin_prefetch is the locality that it's not supported on SH architectures. It has been set to three and it should be verified if it's suitable for SH2A as well. I didn't test on this architecture. The builtin usage should be more efficient that an __asm__ because less barriers, and because the compiler doesn't see the inst as a "black box" allowing better code generation. This has been already done on other architectures (see the commit: 0453fb3c528c5eb3483441a466b24a4cb409eec5). Many thanks to Christian Bruel <[email protected]> for his support on evaluate the impact of the gcc built-in on SH4 arch. No regressions found while testing with LMbench on STLinux targets.

Delete unused I2C adapter IDs. Special cases are: * I2C_HW_B_RIVA was still set in driver rivafb, however no other driver is ever looking for this value, so we can safely remove it. * I2C_HW_B_HDPVR is used in staging driver lirc_zilog, however no adapter ID is ever set to this value, so the code in question never runs. As the code additionally expects that I2C_HW_B_HDPVR may not be defined, we can delete it now and let the lirc_zilog driver maintainer rewrite this piece of code.

2010-11-15Fix gcc 4.5.1 miscompiling drivers/char/i8k.c (again)Jim Bos1-4/+4
The fix in commit 6b4e81db2552 ("i8k: Tell gcc that *regs gets clobbered") to work around the gcc miscompiling i8k.c to add "+m (*regs)" caused register pressure problems and a build failure. Changing the 'asm' statement to 'asm volatile' instead should prevent that and works around the gcc bug as well, so we can remove the "+m". [ Background on the gcc bug: a memory clobber fails to mark the function the asm resides in as non-pure (aka "__attribute__((const))"), so if the function does nothing else that triggers the non-pure logic, gcc will think that that function has no side effects at all. As a result, callers will be mis-compiled. Adding the "+m" made gcc see that it's not a pure function, and so does "asm volatile". The problem was never really the need to mark "*regs" as changed, since the memory clobber did that part - the problem was just a bug in the gcc "pure" function analysis - Linus ] Signed-off-by: Jim Bos <[email protected]> Acked-by: Jakub Jelinek <[email protected]> Cc: Andi Kleen <[email protected]> Cc: Andreas Schwab <[email protected]> Signed-off-by: Linus Torvalds <[email protected]>

When asked to clear the intrusion alarm, do so immediately. We have to invalidate the cache to make sure the new status will be read. But we also have to read from the status register once to clear the pending alarm, as writing to CLR_CHS surprising won't clear it automatically.

2010-11-15hwmon: (w83795) Read the intrusion state properlyJean Delvare1-3/+20
We can't read the intrusion state from the real-time alarm registers as we do for all other alarm flags, because real-time alarm bits don't stick (by definition) and the intrusion state has to stick until explicitly cleared (otherwise it has little value.) So we have to use the interrupt status register instead, which is read from the same address but with a configuration bit flipped in another register.

2010-11-15GFS2: Fix inode deallocation raceSteven Whitehouse5-216/+98
This area of the code has always been a bit delicate due to the subtleties of lock ordering. The problem is that for "normal" alloc/dealloc, we always grab the inode locks first and the rgrp lock later. In order to ensure no races in looking up the unlinked, but still allocated inodes, we need to hold the rgrp lock when we do the lookup, which means that we can't take the inode glock. The solution is to borrow the technique already used by NFS to solve what is essentially the same problem (given an inode number, look up the inode carefully, checking that it really is in the expected state). We cannot do that directly from the allocation code (lock ordering again) so we give the job to the pre-existing delete workqueue and carry on with the allocation as normal. If we find there is no space, we do a journal flush (required anyway if space from a deallocation is to be released) which should block against the pending deallocations, so we should always get the space back.
