2007-07-16Introduce compat_u64 and compat_s64 typesArnd Bergmann
One common problem with 32 bit system call and ioctl emulation is the different alignment rules between i386 and 64 bit machines. A number of drivers work around this by marking the compat structures as 'attribute((packed))', which is not the right solution because it breaks all the non-x86 architectures that want to use the same compat code. Hopefully, this patch improves the situation, it introduces two new types, compat_u64 and compat_s64. These are defined on all architectures to have the same size and alignment as the 32 bit version of u64 and s64. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Acked-by: David S.

2007-07-12[MIPS] SMTC: Interrupt mask backstop hackKevin D. Kissell
To support multiple TC microthreads acting as "CPUs" within a VPE, VPE-wide interrupt mask bits must be specially manipulated during interrupt handling. To support legacy drivers and interrupt controller management code, SMTC has a "backstop" to track and if necessary restore the interrupt mask. This has some performance impact on interrupt service overhead. Disable it only if you know what you are doing. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

2007-07-11PCI: Use a weak symbol for the empty version of pcibios_add_platform_entries()Michael Ellerman
I'm not sure if this is going to fly, weak symbols work on the compilers I'm using, but whether they work for all of the affected architectures I can't say. I've cc'ed as many arch maintainers/lists as I could find. But assuming they do, we can use a weak empty definition of pcibios_add_platform_entries() to avoid having an empty definition on every arch.

2007-07-10[MIPS] Fix PHYS_OFFSET for 64-bits kernels with 32-bits symbolsFranck Bui-Huu
The current implementation of __pa() for 64-bits kernels with 32-bits symbols is broken. In this configuration, we need 2 values for PAGE_OFFSET, one in XKPHYS and the other in CKSEG0 space. When the value in CKSEG0 space is used, it doesn't take into account of PHYS_OFFSET. Even worse we can't redefine this value. The patch restores CPHYSADDR() but in __pa()'s implementation because it removes the need of 2 PAGE_OFFSET. OTOH, CPHYSADDR() is quite bad when dealing with mapped kernels. So this patch assumes there's no need to deal with such kernel in 64-bits world. Signed-off-by: Franck Bui-Huu <fbuihuu@gmail.com> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

Before this patch, when a platform needed to customize one constant in spaces.h, they need to redefine all of them.

This will avoid some macro duplications. It's important specially if we'll add complex macros.
