| * | | Posix timers: limit number of timers firing at onceLinus Torvalds2005-10-231-6/+14
| |/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Bursty timers aren't good for anybody, very much including latency for other programs when we trigger lots of timers in interrupt context. So set a random limit, after which we'll handle the rest on the next timer tick. Noted by Oleg Nesterov <oleg@tv-sign.ru> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

| * | [AX.25]: Fix signed char bugRalf Baechle2005-10-221-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On architectures where the char type defaults to unsigned some of the arithmetic in the AX.25 stack to fail, resulting in some packets being dropped on receive.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | IPVS used flag NFC_IPVS_PROPERTY in nfcache but as now nfcache was removed the new flag 'ipvs_property' still needs to be copied.

My bad. /o\ Lamont confirmed that instructions following a conditional branch are *alway* executed regardless if the branch is taken or not. Unless they are nullified (which was missing in this case). He also noted: Conditional branches nullify on forward taken branch, and on non-taken backward branch. Note that .+4 is a backwards branch. This makes alot more sense than the giberish in the PA20 arch book. Compiles and boots on both 64-bit (a500) and 32-bit (j6k).

* | | [PARISC] Fix the alloc_slabmgmt panicJames Bottomley2005-10-212-6/+36
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix the alloc_slabmgmt panic Hopefully this should also fix a lot of other intermittent kernel bugs. The problem has been around since 2.6.9-rc2-pa6 when we allowed floating point registers to be used in kernel code. The essence of the problem is that gcc prefers to use floating point for integer divides and multiples. Further, it can rely on the values in the no clobber fp regs being correct across a function call. Unfortunately, our task switch function only saves the integer no clobber registers, not the fp ones, so if gcc makes a function call to any function in the kernel which could sleep, the values it is relying on in any no clobber floating point register may be lost. In the case of alloc_slabmgmt, the value of the page offset is being stored in %fr12 across a call to kmem_getpages(), which sleeps if no pages are available. Thus, the offset can be trashed and the slab code can end up with a completely bogus address leading to corruption. Kudos to Randolph who came up with the program to trip this problem at will and thus allowed it to be tracked and fixed.

* | | [PARISC] Update spinlocks from parisc treeMatthew Wilcox2005-10-213-14/+30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Neaten up the CONFIG_PA20 ifdefs More merge fixes, this time for SMP Signed-off-by: Matthew Wilcox <willy@parisc-linux.org> Prettify the CONFIG_DEBUG_SPINLOCK __SPIN_LOCK_UNLOCKED initializers. Clean up some warnings with CONFIG_DEBUG_SPINLOCK enabled. Fix build with spinlock debugging turned on. Patch is cleaner like this, too. Remove mandatory 16-byte alignment requirement on PA2.0 processors by using the ldcw,CO completer. Provides a nice insn savings. Signed-off-by: Kyle McMartin <kyle@parisc-linux.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | move pa_tlb_lock and it's primary consumers to tlb_flush.h Future step will be to move spinlock_t definition out of system.h. Signed-off-by: Grant Grundler <grundler@parisc-linux.org> Signed-off-by: Kyle McMartin <kyle@parisc-linux.org>
* | | [PARISC] Make sure use of RFI conforms to PA 2.0 and 1.1 arch docsGrant Grundler2005-10-217-160/+146
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 2.6.12-rc4-pa3 : first pass at making sure use of RFI conforms to PA 2.0 arch pages F-4 and F-5, PA 1.1 Arch page 3-19 and 3-20. The discussion revolves around all the rules for clearing PSW Q-bit. The hard part is meeting all the rules for "relied upon translation". .align directive is used to guarantee the critical sequence ends more than 8 instructions (32 bytes) from the end of page.
