2005-09-01[PATCH] ppc: L2 cache prefetch fixes on 745xKumar Gala
We run into problems if we blindly enable L2 prefetching without checking that the L2 cache is actually enabled. Additionaly, if we disable the L2 cache we need to ensure that we disable L2 prefetching.

2005-09-01[PATCH] Fix bug in ppc64 dynamic hugepage supportDavid Gibson
In adjusting the logic for SLB miss for the dynamic hugepage stuff, I messed up the !CONFIG_HUGETLB_PAGE case, failing to set the SLB flags properly. This fixes it. It also streamlines the logic for the HUGETLB_PAGE case (removing a couple of branches) while we're at it. Booted, and roughly tested on POWER5 (with and without HUGETLB_PAGE), iSeries/RS64 (no hugepage available), and G5 (with and without HUGETLB_PAGE).

2005-09-01[ARM] 2865/2: fix fadvise64_64 syscall argument passingNicolas Pitre
Patch from Nicolas Pitre The prototype for sys_fadvise64_64() is: long sys_fadvise64_64(int fd, loff_t offset, loff_t len, int advice) The argument list is therefore as follows on legacy ABI: fd: type int (r0) offset: type long long (r1-r2) len: type long long (r3-sp[0]) advice: type int (sp[4]) With EABI this becomes: fd: type int (r0) offset: type long long (r2-r3) len: type long long (sp[0]-sp[4]) advice: type int (sp[8]) Not only do we have ABI differences here, but the EABI version requires one additional word on the syscall stack. To avoid the ABI mismatch and the extra stack space required with EABI this syscall is now defined with a different argument ordering on ARM as follows: long sys_arm_fadvise64_64(int fd, int advice, loff_t offset, loff_t len) This gives us the following ABI independent argument distribution: fd: type int (r0) advice: type int (r1) offset: type long long (r2-r3) len: type long long (sp[0]-sp[4]) Now, since the syscall entry code takes care of 5 registers only by default including the store of r4 to the stack, we need a wrapper to store r5 to the stack as well. Because that wrapper was missing and was always required this means that sys_fadvise64_64 never worked on ARM and therefore we can safely reuse its syscall number for our new sys_arm_fadvise64_64 interface.

2005-08-30[PATCH] x86: pci_assign_unassigned_resources() updateIvan Kokshaysky
I had some time to think about PCI assign issues in 2.6.13-rc series. The major problem here is that we call pci_assign_unassigned_resources() way too early - at subsys_initcall level. Therefore we give no chances to ACPI and PnP routines (called at fs_initcall level) to reserve their respective resources properly, as the comments in drivers/pnp/system.c and drivers/acpi/motherboard.c suggest: /** * Reserve motherboard resources after PCI claim BARs, * but before PCI assign resources for uninitialized PCI devices */ So I moved the pci_assign_unassigned_resources() call to pcibios_assign_resources() (fs_initcall), which should hopefully fix a lot of problems and make PCIBIOS_MIN_IO tweaks unnecessary. Other changes: - remove resource assignment code from pcibios_assign_resources(), since it duplicates pci_assign_unassigned_resources() functionality and actually does nothing in 2.6.13; - modify ROM assignment code as per Ben's suggestion: try to use firmware settings by default (if PCI_ASSIGN_ROMS is not set); - set CARDBUS_IO_SIZE back to 4K as it's a wonderful stress test for various setups. Confirmed by Tero Roponen <teanropo@cc.jyu.fi> (who had problems with the 4kB CardBus IO size previously). Signed-off-by: Linus Torvalds <torvalds@osdl.org>

2005-08-30[PATCH] Remove nested feature sectionsDavid Gibson
The {BEGIN,END}_FTR_SECTION asm macros used in ppc64 to nop out sections of code at runtime cannot be nested. However, we do nest them in hash_low.S. We get away with it there, because there is nothing between the BEGIN markers for each section. However, that's confusing to someone reading the code. This patch removes the nested ifset and ifclr feature sections, replacing them with a single feature section in the full mask/value form.

2005-08-30[PATCH] PPC64: Don't try to claim memory from OF at 1GB markOlof Johansson
Some RS64-based machines (p620, F80, others) have problems with firmware returning 0xdeadbeef instead of failure to allocations that end at the 1GB mark. We have two options: 1. Detect the undocumented 0xdeadbeef return value and interpret it as a failure. 2. Avoid allocating that high. (2) is really the cleaner solution here. 768MB is plenty of room so use that as the max alloc_top instead of 1GB.

2005-08-30[PATCH] fix iSeries build for gcc-3.4Stephen Rothwell
gcc 3.4 (at least the build we are using) puts the gcc generated .ident string into a .note section at the end of the files it compiles (gcc 3.3.3-hammer and gcc 4.0.2 Debian puts it in the .text section). This means that the lparmap.s file we produce in the iSeries build may end with a .note section. When we include it into head.S, the assembler can no longer resolve some of the conditional branches since the target label ends up too far away. This patch just forces us back to the .text section after including lparmap.s. The breakage was caused by my patch "iSeries build with newer assemblers and compilers" (sha1-id: 2ad56496627630ebc99f06af5f81ca23e17e014e).

2005-08-29[ARM] 2853/1: Make alloc_init_supersection() work with 36-bit mappingsDeepak Saxena
Patch from Deepak Saxena Working on adding support for 36-bit static mappings for ARMv6 and Intel's XSC3 core and noticed that alloc_init_supersection currently increments the phys addr by 1MB on each of the 16 iterations and then forces alignment to supersection size (16MB). This is really uneeded b/c we have already forced the phys address to be 16MB aligned in create_mapping(). Furthermore, this breaks 36-bit addressing b/c bits [23:20] of the PMD contain bits [35:32] of the physical address and the masking causes us to loose those bits thus ending up with an incorrect virt -> phys translation. The other option is to have an alloc_init_supersection36. Tested on Intel IXP2350 CPU with 36-bit static I/O mappings.

2005-08-29[SPARC64]: More fully work around Spitfire Errata 51.David S. Miller
It appears that a memory barrier soon after a mispredicted branch, not just in the delay slot, can cause the hang condition of this cpu errata.
