2007-03-17[MIPS] RTLX: Harden against compiler reordering and optimization.Ralf Baechle
RTLX communication is based on lock-free shared memory buffers. It happened to be working by luck so far but relies on the optimizer doing certain optimizations but no reordering. Fixed by inserting proper barriers in rtlx_read and rtlx_write, and careful pointer dereferencing. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

2007-02-12[PATCH] mark struct file_operations const 2Arjan van de Ven
Many struct file_operations in the kernel can be "const". Marking them const moves these to the .rodata section, which avoids false sharing with potential dirty data. In addition it'll catch accidental writes at compile time to these shared resources.

2007-02-06[MIPS] Define MIPS_CPU_IRQ_BASE in generic headerAtsushi Nemoto
The irq_base for {mips,rm7k,rm9k}_cpu_irq_init() are constant on all platforms and are same value on most platforms (0 or 16, depends on CONFIG_I8259). Define them in asm-mips/mach-generic/irq.h and make them customizable. This will save a few cycle on each CPU interrupt. A good side effect is removing some dependencies to MALTA in generic SMTC code. Although MIPS_CPU_IRQ_BASE is customizable, this patch changes irq mappings on DDB5477, EMMA2RH and MIPS_SIM, since really customizing them might cause some header dependency problem and there seems no good reason to customize it. So currently only VR41XX is using custom MIPS_CPU_IRQ_BASE value, which is 0 regardless of CONFIG_I8259. Testing this patch on those platforms is greatly appreciated. Thank you.
