2009-06-16kmap_types: make most arches use generic header fileRandy Dunlap1-21/+3
Convert most arches to use asm-generic/kmap_types.h. Move the KM_FENCE_ macro additions into asm-generic/kmap_types.h, controlled by __WITH_KM_FENCE from each arch's kmap_types.h file. Would be nice to be able to add custom KM_types per arch, but I don't yet see a nice, clean way to do that. Built on x86_64, i386, mips, sparc, alpha(tonyb), powerpc(tonyb), and 68k(tonyb). Note: avr32 should be able to remove KM_PTE2 (since it's not used) and then just use the generic kmap_types.h file. Get avr32 maintainer approval.

2009-06-16time: move PIT_TICK_RATE to linux/timex.hArnd Bergmann1-2/+0
PIT_TICK_RATE is currently defined in four architectures, but in three different places. While linux/timex.h is not the perfect place for it, it is still a reasonable replacement for those drivers that traditionally use asm/timex.h to get CLOCK_TICK_RATE and expect it to be the PIT frequency. Note that for Alpha, the actual value changed from 1193182UL to 1193180UL. This is unlikely to make a difference, and probably can only improve accuracy. There was a discussion on the correct value of CLOCK_TICK_RATE a few years ago, after which every existing instance was getting changed to 1193182. According to the specification, it should be 1193181.818181...

2009-06-15mips: remove driver_data direct access of struct deviceGreg Kroah-Hartman1-1/+1
In the near future, the driver core is going to not allow direct access to the driver_data pointer in struct device. Instead, the functions dev_get_drvdata() and dev_set_drvdata() should be used. These functions have been around since the beginning, so are backwards compatible with all older kernel versions.

2009-06-11asm-generic: introduce asm/bitsperlong.hArnd Bergmann2-3/+8
This provides a reliable way for asm-generic/types.h and other files to find out if it is running on a 32 or 64 bit platform. We cannot use CONFIG_64BIT for this in headers that are included from user space because CONFIG symbols are not available there. We also cannot do it inside of asm/types.h because some headers need the word size but cannot include types.h. The solution is to introduce a new header <asm/bitsperlong.h> that defines both __BITS_PER_LONG for user space and BITS_PER_LONG for usage in the kernel. The asm-generic version falls back to 32 bit unless the architecture overrides it, which I did for all 64 bit platforms.

2009-06-08MIPS: Outline udelay and fix a few issues.Ralf Baechle5-92/+66
Outlining fixes the issue were on certain CPUs such as the R10000 family the delay loop would need an extra cycle if it overlaps a cacheline boundary. The rewrite also fixes build errors with GCC 4.4 which was changed in way incompatible with the kernel's inline assembly. Relying on pure C for computation of the delay value removes the need for explicit. The price we pay is a slight slowdown of the computation - to be fixed on another day.

2009-05-14MIPS: Fix sign-extension bug in 32-bit kernel on 32-bit hardware.Ralf Baechle1-4/+4
Probably nobody does arithmetic on cp0 register values so this has never bitten. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2009-05-14MIPS: MSP71xx: Remove the RAMROOT functionsShane McDonald2-71/+1
The RAMROOT function was a successful but non-portable attempt to append the root filesystem to the end of the kernel image. The preferred and portable solution is to use an initramfs instead. Signed-off-by: Shane McDonald <mcdonald.shane@gmail.com> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2009-05-14MIPS: Use -mno-check-zero-divisionRalf Baechle1-0/+1
I don't think that in 15 years of Linux/MIPS the zero division checking code generated by gcc by default has ever caught anything. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2009-05-14MIPS: Set compiler options only after the compiler prefix has ben set.Ralf Baechle1-2/+2
Otherwise indigestable options might be passed to the host compiler. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
