From d9cdc901af0f92da7f90c750d8c187f5500be067 Mon Sep 17 00:00:00 2001 From: Ralf Baechle Date: Fri, 17 Jun 2011 16:20:28 +0100 Subject: MIPS: cache: Provide cache flush operations for XFS Until now flush_kernel_vmap_range() and invalidate_kernel_vmap_range() did not exist on MIPS resulting in heavy cache corruption on XFS filesystems. Left for the post-3.0 time: optimization and make this work with highmem, too. Since the combination of highmem + cache aliases atm doesn't work this isn't a regression.

Turns out this patch is producing many build errors with gcc 4.2. Based on further testing with a test case extracted from the build errors found further build errors and suboptimal generation even in violation of the "R" constraint. To make matters worse, the binutils changes also don't work quite as intended so revert this patch for now. --- arch/mips/include/asm/io.h | 12 ++---------- 1 file changed, 2 insertions(+), 10 deletions(-) (limited to 'arch/mips/include') diff --git a/arch/mips/include/asm/io.h b/arch/mips/include/asm/io.h index b04e4de5dd2e..a58f22998a86 100644 --- a/arch/mips/include/asm/io.h +++ b/arch/mips/include/asm/io.h @@ -329,14 +329,10 @@ static inline void pfx##write##bwlq(type val, \ "dsrl32 %L0, %L0, 0" "\n\t" \ "dsll32 %M0, %M0, 0" "\n\t" \ "or %L0, %L0, %M0" "\n\t" \ - ".set push" "\n\t" \ - ".set noreorder" "\n\t" \ - ".set nomacro" "\n\t" \ "sd %L0, %2" "\n\t" \ - ".set pop" "\n\t" \ ".set mips0" "\n" \ : "=r" (__tmp) \ - : "0" (__val), "R" (*__mem)); \ + : "0" (__val), "m" (*__mem)); \ if (irq) \ local_irq_restore(__flags); \ } else \ @@ -359,16 +355,12 @@ static inline type pfx##read##bwlq(const volatile void __iomem *mem) \ local_irq_save(__flags); \ __asm__ __volatile__( \ ".set mips3" "\t\t# __readq" "\n\t" \ - ".set push" "\n\t" \ - ".set noreorder" "\n\t" \ - ".set nomacro" "\n\t" \ "ld %L0, %1" "\n\t" \ - ".set pop" "\n\t" \ "dsra32 %M0, %L0, 0" "\n\t" \ "sll %L0, %L0, 0" "\n\t" \ ".set mips0" "\n" \ : "=r" (__val) \ - : "R" (*__mem)); \ + : "m" (*__mem)); \ if (irq) \ local_irq_restore(__flags); \ } else { \ -- cgit v1.2.3 From ce1d43b9a9e8a3db8fe91696c0b0e3ac1a154e34 Mon Sep 17 00:00:00 2001 From: Manuel Lauss Date: Tue, 2 Aug 2011 19:51:03 +0200 Subject: MIPS: Alchemy: support multiple GPIO styles in one kernel For GPIOLIB=y decide at runtime which gpiochips to register; in the GPIOLIB=n case, the gpio headers need to be reshuffled a bit to make multiple implementations coexist peacefully.
