2008-04-17Pb1200/DBAu1200: fix bad IDE resource sizeSergei Shtylyov
The header files for the Pb1200/DBAu1200 boards have wrong definition for the IDE interface's decoded range length -- it should be 512 bytes according to what the IDE driver does. In addition, the IDE platform device claims 1 byte too many for its memory resource -- fix the platform code and the IDE driver in accordance.

2008-04-01[MIPS] Alchemy: work around clock misdetection on early Au1000Sergei Shtylyov
Work around the CPU clock miscalculation on Au1000DA/HA/HB due the sys_cpupll register being write-only, i.e. actually do what the comment before cal_r4off() function advertised for years but the code failed at. This is achieved by just giving user a chance to define the clock explicitly in the board config. via CONFIG_SOC_AU1000_FREQUENCY option, defaulting to 396 MHz if the option is not given... The patch is based on the AMD's big unpublished patch, the issue seems to be an undocumented errata (or feature :-)...

2007-02-14[PATCH] sysctl: remove insert_at_head from register_sysctlEric W. Biederman
The semantic effect of insert_at_head is that it would allow new registered sysctl entries to override existing sysctl entries of the same name. Which is pain for caching and the proc interface never implemented. I have done an audit and discovered that none of the current users of register_sysctl care as (excpet for directories) they do not register duplicate sysctl entries. So this patch simply removes the support for overriding existing entries in the sys_sysctl interface since no one uses it or cares and it makes future enhancments harder. Signed-off-by: Eric W.

2007-01-10 [MIPS] Alchemy: Fix PCI-memory accessAlexander Bigga
The problem was introduced in 2.6.18.3 with the casting of some 36bit-defines (PCI memory) in au1000.h to resource_size_t which may be u32 or u64 depending on the experimental CONFIG_RESOURCES_64BIT. With unset CONFIG_RESOURCES_64BIT, the pci-memory cannot be accessed because the ioremap in arch/mips/au1000/common/pci.c already used the truncated addresses. With set CONFIG_RESOURCES_64BIT, things get even worse, because PCI-scan aborts, due to resource conflict: request_resource() in arch/mips/pci/pci.c fails because the maximum iomem-address is 0xffffffff (32bit) but the pci-memory-start-address is 0x440000000 (36bit). To get pci working again, I propose the following patch: 1. remove the resource_size_t-casting from au1000.h again 2. make the casting in arch/mips/au1000/common/pci.c (it's allowed and necessary here. The 36bit-handling will be done in __fixup_bigphys_addr). With this patch pci works again like in 2.6.18.2, the gcc-compile warnings in pci.c are gone and it doesn't depend on CONFIG_EXPERIMENTAL.

2006-11-30[MIPS] IRQ cleanupsAtsushi Nemoto
This is a big irq cleanup patch. * Use set_irq_chip() to register irq_chip. * Initialize .mask, .unmask, .mask_ack field. Functions for these method are already exist in most case. * Do not initialize .startup, .shutdown, .enable, .disable fields if default routines provided by irq_chip_set_defaults() were suitable. * Remove redundant irq_desc initializations. * Remove unnecessary local_irq_save/local_irq_restore, spin_lock. With this cleanup, it would be easy to switch to slightly lightwait irq flow handlers (handle_level_irq(), etc.) instead of __do_IRQ(). Though whole this patch is quite large, changes in each irq_chip are not quite simple. Please review and test on your platform. Thanks.
