2010-05-06microblaze: Optimize CACHE_LOOP_LIMITS and CACHE_RANGE_LOOP macrosMichal Simek1-27/+35
1. Remove CACHE_ALL_LOOP2 macro because it is identical to CACHE_ALL_LOOP 2. Change BUG_ON to WARN_ON 3. Remove end aligned from CACHE_LOOP_LIMITS. C implementation do not need aligned end address and ASM code do aligned in their macros 4. ASM optimized CACHE_RANGE_LOOP_1/2 macros needs to get aligned end address. Because end address is compound from start + size, end address is the first address which is exclude. Here is the corresponding code which describe it. + int align = ~(line_length - 1); + end = ((end & align) == end) ? end - line_length : end & align; a) end is aligned: it is necessary to subtruct line length because we don't want to work with next cacheline b) end address is not aligned: Just align it to be ready for ASM code.

2010-05-06microblaze: Define correct L1_CACHE_SHIFT valueMichal Simek1-1/+1
Microblaze cacheline length is configurable and current cpu uses two cacheline length 4 and 8. We are taking conservative maximum value to be sure that cacheline alignment is satisfied for all cases. Here is the calculation for cacheline lenght 8 32bit=4Byte values which is corresponding with SHIFT 5. Signed-off-by: Michal Simek <monstr@monstr.eu>

Based on PowerPC patche 52142e756e9bf6485d3d53596e8aff2e816a7253 PowerPC description: On platforms doing non-coherent DMA (4xx, 8xx, ...), it's important that the kmalloc minimum alignment is set to the cache line size, to avoid sharing cache lines between different objects, so that DMA to one of the objects doesn't corrupt the other.

2010-05-06microblaze: Remove "cache" optimized copy_page functionMichal Simek3-39/+2
Current implementation doesn't handle dcache_line_length correctly that's why is better to use generic memcpy. Cache optimized function could be good way howto improve performance but must be based on benchmarking not blind function like this. Signed-off-by: Michal Simek <monstr@monstr.eu>
2010-05-06microblaze: invoke oom-killer from page faultNick Piggin1-9/+4

Remove section mismatch - based on ppc aproach. WARNING: vmlinux.o(.text+0x64834): Section mismatch in reference from the function __pte_alloc_kernel() to the function .init.text:early_get_page() The function __pte_alloc_kernel() references the function __init early_get_page(). This is often because __pte_alloc_kernel lacks a __init annotation or the annotation of early_get_page is wrong. Signed-off-by: Michal Simek <monstr@monstr.eu>

This doesn't change the way resources are stored; it merely removes dependencies on the fact that they're in a table. Signed-off-by: Michal Simek <monstr@monstr.eu>

2010-04-30MIPS: Loongson 2F: Fix of problems introduced by -mfix-loongson2f-jumpWu Zhangjin1-1/+19
The -mfix-loongson2f-jump option provided by latest CVS binutils have fixed the out-of-order issue of Loongson-2F described in chapter 15 of the Loongson2F User Manual [1, 2], but introduced some problems. The option changes all of the jump target to "addr & 0xcfffffff" through the at($1) register, but for the reboot address of Loongson 2F 0xbfc00000 this is wrong. Avoids the problem via telling the assembler to not use the $at register.
