2005-10-20[PATCH] powerpc: Merge ppc64 pmc.[ch] with ppc32 perfmon.[ch]David Gibson
This patches the ppc32 and ppc64 versions of the headers and .c files with helper functions for manipulating the performance counting hardware. As a side effect, it removes use of the term "perfmon" from ppc32, thus avoiding confusion with the unrelated performance counter interface from HP Labs also called "perfmon". Built, but not booted, for g5, pSeries, iSeries, and 32-bit Powermac with both ARCH=powerpc and ARCH=ppc{,64} as appropriate.

2005-10-20[PATCH] ppc32: replace use of _GLOBAL with .globl for ppc32Kumar Gala
The _GLOBAL() macro is for text symbols only. Changed to using .globl for .data symbols. This is also needed in ppc32 land to allow FSL Book-E, 40x, and 44x to work. Signed-off-by: Kumar K. Gala <kumar.gala@freescale.com> Signed-off-by: Paul Mackerras <paulus@samba.org>

Some minor fixes that are needed if we are building for a book-e processor. Signed-off-by: Kumar K. Gala <kumar.gala@freescale.com> Signed-off-by: Paul Mackerras <paulus@samba.org>
2005-10-20powerpc: Fix a corner case in __div64_32Paul Mackerras
The code was incorrectly doing a division by 0 in the case where the denominator was 0x100000000 and the divisor was 0xffffffff. Thanks to Fred Liu of Motorola for pointing this out. Signed-off-by: Paul Mackerras <paulus@samba.org>

2005-10-20powerpc: Merge time.c and asm/time.h.Paul Mackerras
We now use the merged time.c for both 32-bit and 64-bit compilation with ARCH=powerpc, and for ARCH=ppc64, but not for ARCH=ppc32. This removes setup_default_decr (folds its function into time_init) and moves wakeup_decrementer into time.c. This also makes an asm-powerpc/rtc.h. Signed-off-by: Paul Mackerras <paulus@samba.org>
2005-10-20ppc64: Minor compilation fixesPaul Mackerras
This defines CONFIG_PPC_STD_MMU for ppc64, changes an instance of sys32_ to compat_sys_ in the ppc64 syscall table, and removes a reference to a non-existent arch/powerpc/xmon/Makefile. Signed-off-by: Paul Mackerras <paulus@samba.org>
2005-10-20powerpc: Move ptrace32.c from arch/ppc64 to arch/powerpcPaul Mackerras
Also corrected my email address in ptrace.c and updated the comments at the top of ptrace32.c. Signed-off-by: Paul Mackerras <paulus@samba.org>
2005-10-19powerpc: Eliminate a compile warning in signal_32.cPaul Mackerras
The second argument of get_sigset_t needed to have the const keyword. Signed-off-by: Paul Mackerras <paulus@samba.org>
2005-10-19powerpc: Merge machdep.hPaul Mackerras
A few things change for consistency between ppc32 and ppc64: idle functions return void; *_get_boot_time functions return unsigned long (i.e. time_t) rather than filling in a struct rtc_time (since that's useful to the callers and easier for pmac to generate); *_get_rtc_time and *_set_rtc_time functions take a struct rtc_time; irq_canonicalize is gone; nvram_sync returns void. Signed-off-by: Paul Mackerras <paulus@samba.org>
2005-10-19ppc: Minor smp changes for consistency with ppc64Paul Mackerras
This makes platform code use the smp_ops variable directly instead of ppc_md.smp_ops, removes the two unused `data' and `wait' arguments from the *_message_pass() functions, and removes the call to the never-implemented smp_ops->space_timers() function.

2005-10-18powerpc: change sys32_ to compat_sys_Stephen Rothwell
This allows us to get rid of one type of entry in systbl.S. In passing we remove the duplicate compat_sys_getdents and compat_sys_utimes for which there are generic versions. Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au>
2005-10-18powerpc: Fix various compile errors with ARCH=ppc, ppc64 and powerpcPaul Mackerras
This makes ppc use the syscalls.c from arch/powerpc/kernel, exports copy_and_flush from head_32.S for use by prom_init.c (ARCH=powerpc), and consolidates the sys_fadvise64_64 implementations for 32-bit. Signed-off-by: Paul Mackerras <paulus@samba.org>

2005-10-17[PATCH] powerpc: Another maple merge tree fixDavid Gibson

2005-10-17[PATCH] powerpc: Fix use of LOADBASE in merge treeDavid Gibson
The merge-tree version of LOADBASE actually loads the whole given address from the toc for ppc64. The matching OFF macro adjust for this, using an offset of 0 for ppc64, but we weren't using that in power4_idle.

2005-10-17powerpc: Initialize btext subsystem later, after prom_initPaul Mackerras
We were initializing the btext stuff from prom_init(), thus breaking the rule that all communication between prom_init() and the rest of the kernel has to be via the flattened device tree. This removes the btext initialization calls from prom_init() and initializes it instead after the device tree is unflattened. It would be nice to do it earlier, but that needs some more infrastructure to find the properties we need in the flattened device tree. Signed-off-by: Paul Mackerras <paulus@samba.org>

2005-10-14powerpc: move iSeries/iSeries_pci.h to platforms/iseriesStephen Rothwell
The only real user of this file outside platforms/iseries was drivers/net/iseries_veth.c but all it wanted was ISERIES_HV_ADDR() so we move that to abs_addr.h (and lowercase it). Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au>

2005-10-12powerpc: Move default hash table size calculation to hash_utils_64.cPaul Mackerras
We weren't computing the size of the hash table correctly on iSeries because the relevant code in prom.c was #ifdef CONFIG_PPC_PSERIES. This moves the code to hash_utils_64.c, makes it unconditional, and cleans it up a bit. Signed-off-by: Paul Mackerras <paulus@samba.org>

2005-10-12powerpc: make iSeries boot againStephen Rothwell
On ARCH=ppc64 we were getting htab_hash_mask recalculated to the correct value for our particular machine by accident. In the merge tree, that code was commented out, so htab_hash_mask was being corrupted. We now set ppc64_pft_size instead which gets htab_has_mask calculated correctly for us later. We should put an ibm,pft-size property in the device tree at some point. Also set -mno-minimal-toc in some makefiles. Allow iSeries to configure PROC_DEVICETREE.

2005-10-11[SPARC64]: Fix net booting on Ultra5David S. Miller
We were not doing alignment properly when remapping the kernel image. What we want is a 4MB aligned physical address to map at KERNBASE. Mistakedly we were 4MB aligning the virtual address where the kernel initially sits, that's wrong. Instead, we should PAGE align the virtual address, then 4MB align the physical address result the prom gives to us. Signed-off-by: David S. Miller <davem@davemloft.net>

2005-10-11[PATCH] ppc highmem fixPaolo Galtieri
I've noticed that the calculations for seg_size and nr_segs in __dma_sync_page_highmem() (arch/ppc/kernel/dma-mapping.c) are wrong. The incorrect calculations can result in either an oops or a panic when running fsck depending on the size of the partition. The problem with the seg_size calculation is that it can result in a negative number if size is offset > size. The problem with the nr_segs caculation is returns the wrong number of segments, e.g. it returns 1 when size is 200 and offset is 4095, when it should return 2 or more.

2005-10-11[PATCH] ppc64: Fix PCI hotplugAnton Blanchard
pSeries_irq_bus_setup is marked __devinit but references s7a_workaround which is marked __initdata. Depending on who got the memory for s7a_workaround (and if the value was now positive), it was possible for PCI hotplugged devices to have 3 subtracted from their interrupt number. This would happen randomly and caused me much confusion :) Signed-off-by: Anton Blanchard <anton@samba.org> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
