* kbuild: set correct KBUILD_MODNAME when using well known kernel symbols as ↵Ustyugov Roman2005-12-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | module names This patch fixes a problem when we use well known kernel symbols as module names. For example, if module source name is current.c, idle_stack.c or etc., we have a bad KBUILD_MODNAME value. For example, KBUILD_MODNAME will be "get_current()" instead of "current", or "(init_thread_union.stack)" instead of "idle_task". The trick is to define a stringify macro on the commandline - named KBUILD_STR for namespace reasons - and then to stringify the module name. There are a few uses of KBUILD_MODNAME throughout the tree but the usage is for debug and will not be harmed by this change so left untouched for now. While at it KBUILD_BASENAME was changed too. Any spinlock usage in the unix module would have created wrong section names without it. Usage in spinlock.h fixed so it no longer stringify KBUILD_BASENAME. Original patch from Ustyogov Roman - all bugs introduced by me. Signed-off-by: Sam Ravnborg <sam@ravnborg.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since taking a spinlock disables preempt, and we need to spinlock tlb flush on SMP for N class, we might as well just spinlock on uniprocessor machines too.

| * | | [PARISC] Fix our spinlock implementationJames Bottomley2005-11-17

The read_lock implementation spins with disabled interrupts. This is completely wrong 2. Our spin_lock_irqsave should check to see if interrupts were enabled before the call and re-enable interrupts around the inner spin loop. The problem is that if we spin with interrupts off, we can't receive IPIs. This has resulted in a bug where SMP machines suddenly spit smp_call_function timeout messages and hang. The scenario I've caught is CPU0 does a flush_tlb_all holding the vmlist_lock for write. CPU1 tries a cat of /proc/meminfo which tries to acquire vmlist_lock for read CPU1 is now spinning with interrupts disabled CPU0 tries to execute a smp_call_function to flush the local tlb caches This is now a deadlock because CPU1 is spinning with interrupts disabled and can never receive the IPI Signed-off-by: James Bottomley <jejb@parisc-linux.org> Signed-off-by: Kyle McMartin <kyle@parisc-linux.org>
| * | | [PARISC] Add IRQ affinitiesJames Bottomley2005-11-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This really only adds them for the machines I can check SMP on, which is CPU interrupts and IOSAPIC (so not any of the GSC based machines). With this patch, irqbalanced can be used to maintain irq balancing. Unfortunately, irqbalanced is a bit x86 centric, so it doesn't do an incredibly good job, but it does work.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since irq.c uses smp_send_all_nop, we must define it for UP builds as well. Make it a static inline so it gets optimized away. This forces irq.c to include <asm/smp.h> though. Signed-off-by: Kyle McMartin <kyle@parisc-linux.org>

| * powerpc: Fix delay functions for 601 processorsPaul Mackerras2005-11-17
| | | | | | | | | | | | | | | | | | | | | | My earlier merge of delay.h introduced a timebase-based udelay for 32-bit machines but also broke the 601, which doesn't have the timebase register. This fixes it by using the 601's RTC register on the 601, and also moves __delay() and udelay() to be out-of-line in arch/powerpc/kernel/time.c. These functions aren't really performance critical, after all. Signed-off-by: Paul Mackerras <paulus@samba.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | PowerPC's NUMA domain doesn't currently set up some of the newer sched-domains parameters. Brian Twichell <tbrian@us.ibm.com> discovered and diagnosed a 1.5% OLTP database regression on a 4 core POWER5 system that was due to the use of NUMA scheduling on ppc64. This patch applies some saneish values to the parameters, in line with other architectures. This solves the regression.

| |/ |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Due to incomplete memory constraints, gcc would miscompile code with sigaddset on i386 if sig arg was const. A quote form Jakub to make the issue clear: "You need either __asm__("btsl %1,%0" : "+m"(*set) : "Ir"(_sig-1) : "cc"); or __asm__("btsl %1,%0" : "=m"(*set) : "Ir"(_sig-1), "m"(*set) : "cc"); because the btsl instruction doesn't just set the memory to some value, but needs to read its previous content as well. If you don't tell that fact to GCC, GCC is of course free to optimize as if the asm was just setting the value and not depended on the previous value."
