| * [SPARC64]: Fix ugly dependency on NR_CPUS being a power-of-2.David S. Miller2005-07-271-6/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | The page->flags D-cache dirty state tracking depended upon NR_CPUS being a power-of-2 via it's "NR_CPUS - 1" masking. Fix that to use a fixed (256 - 1) mask as that is the limit imposed by thread_info->cpu which is a "u8". Finally, add a compile time check that NR_CPUS is not greater than 256.

| * | [IA64] unwind.c uses wrong unat from switch_stackKeith Owens2005-07-271-6/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | unwind.c can read the wrong unat bits from switch_stack. sw->caller_unat is the value of ar.unat when the task was blocked. sw->ar_unat is the value of ar.unat after doing st8.spill for r4-7. IOW, ar_unat is caller_unat with 4 bits changed. unw_access_gr() uses sw->ar_unat for r4-7 (correct), but it also uses sw->ar_unat for other scratch registers (incorrect). sw->ar_unat should only be used for r4-7, everything else should use sw->caller_unat, unless modified by unwind info. Using sw->ar_unat risks picking up the 4 bits that were overwritten when r4-7 were saved. Also this line is wrong unw.sw_off[unw.preg_index[UNW_REG_PFS]] = SW(AR_UNAT); and should be unw.sw_off[unw.preg_index[UNW_REG_PFS]] = SW(AR_PFS); Signed-off-by: Keith Owens <kaos@sgi.com> Signed-off-by: Tony Luck <tony.luck@intel.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On 8xx, in the case where a pagefault happens for a process who's not the owner of the vma in question (ptrace for instance), the flush operation is performed via the physical address. Unfortunately, that results in a strange, unexplainable "icbi" instruction fault, most likely due to a CPU bug (see oops below). Avoid that by flushing the page via its kernel virtual address.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The kernel uses the SIGP external call order code to signal other CPUs. When running with dedicated CPUs external calls don't get delivered immediately but within a fixed polling invervall. This can lead to delays where the system appears to do nothing. Replace the SIGP external call order with the SIGP emergency call order since this one gets delivered immediately.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Split spin lock and r/w lock implementation into a single try which is done inline and an out of line function that repeatedly tries to get the lock before doing the cpu_relax(). Add a system control to set the number of retries before a cpu is yielded. The reason for the spin lock retry is that the diagnose 0x44 that is used to give up the virtual cpu is quite expensive. For spin locks that are held only for a short period of time the costs of the diagnoses outweights the savings for spin locks that are held for a longer timer. The default retry count is 1000.

* | | [PATCH] ppc64: remove another fixed address constraintDavid Gibson2005-07-272-36/+85
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Presently the LparMap, one of the structures the kernel shares with the legacy iSeries hypervisor has a fixed offset address in head.S. This patch changes this so the LparMap is a normally initialized structure, without fixed address. This allows us to use macros to compute some of the values in the structure, which wasn't previously possible because the assembler always uses signed-% which gets the wrong answers for the computations in question. Unfortunately, a gcc bug means that doing this requires another structure (hvReleaseData) to be initialized in asm instead of C, but on the whole the result is cleaner than before.

* | | [PATCH] ppc64: dynamically allocate segment tablesDavid Gibson2005-07-274-22/+37
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | PPC64 machines before Power4 need a segment table page allocated for each CPU. Currently these are allocated statically in a big array in head.S for all CPUs. The segment tables need to be in the first segment (so do_stab_bolted doesn't take a recursive fault on the stab itself), but other than that there are no constraints which require the stabs for the secondary CPUs to be statically allocated. This patch allocates segment tables dynamically during boot, using lmb_alloc() to ensure they are within the first 256M segment. This reduces the kernel image size by 192k... Tested on RS64 iSeries, POWER3 pSeries, and POWER5.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Typo bug that was using PCI1 defines instead of PCI2 when setting up the second PCI bus controller on 85xx based systems. This hasn't been a real issue since currently the PCI2 sizes are the same as the PCI1 sizes for currently supported boards. Thanks to Andrew Klossner @ Xerox for point this out.

| | | | | | | | | | | | | | | | | | | | | | | | The 2.6.12.3 kernel compilation fails for ARCH=ppc when CONFIG_PQ2FADS=y. This patch has been tested on Freescale PQ2FADS-ZU and -VR boards. Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
* | | [PATCH] ppc32: 8xx: update DataTLBMiss exception commentMarcelo Tosatti2005-07-271-7/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On PPC 8xx, the DataTLBMiss handler does not jump directly to the page fault handler, as was the case in v2.4. It instead loads an invalid TLB which causes a subsequent DataTLBError exception. The comment on top of it haven't been update to reflect the change, though.

* | | [PATCH] ppc32: Make the UARTs on MPC824x individual platform devicesKumar Gala2005-07-274-18/+61
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The UARTs on the MPC824x are unique devices and really shouldn't be thought of as a DUART. In addition, if both UARTs are in use we need to configure the part to enable the 2nd UART since the pins for the UARTs are multiplexed. Adds support to run the 824x Sandpoint with both UARTs if desired.
