2009-05-01powerpc: Fix setting of oprofile cpu typeBenjamin Herrenschmidt
commit 2657dd4e301d4841ed67a4fac7d145ad8f3e1b28 introduced a bug where we would now always override the "real" oprofile CPU type with the "compatible" one provided by a pseudo-PVR in the device-tree which is incorrect and breaks oprofile on all current configs since the "compatible" ones aren't yet recognized. This fixes it. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
2009-05-01powerpc adjust oprofile_cpu_type version 3Michael Wolf
Oprofile is changing the naming it is using for the compatibility modes. Instead of having compat-power<x>, oprofile will go to family naming convention and use ibm-compat-v<x>. Currently only ibm-compat-v1 will be defined. The notion of compatibility events just started with POWER6. So there is no way that any other tool could exist that is using these oprofile_cpu_type strings we want to change.

2009-04-30x86: gettimeofday() vDSO: fix segfault when tv == NULLJohn Wright
According to the gettimeofday(2) manual: If either tv or tz is NULL, the corresponding structure is not set or returned. Since it is legal to give NULL as the tv argument, the code should make sure tv is not NULL before trying to dereference it. This issue manifests itself on x86_64 when vdso=0 is not on the kernel command-line and libc uses the vDSO for gettimeofday() (e.g. glibc >= 2.7). A simple reproducer: #include <stdio.h> #include <sys/time.h> int main(void) { struct timezone tz; gettimeofday(NULL, &tz); return 0; } See http://bugs.debian.org/466491 for more details.

2009-04-28powerpc: Revert switch to TEXT_TEXT in linker scriptTim Abbott
Commit edada399 broke the build on 64-bit powerpc because it moved the __ftr_alt_* sections of a file away from the .text section, causing link failures due to relative conditional branch targets being too far away from the branch instructions. This happens on pretty much all 64-bit powerpc configs. This change reverts commit edada399 while preserving the update from the *.refok sections to .ref.text that has happened since.

2009-04-28powerpc/cell: Select PCI for IBM_CELL_BLADE AND CELLEBMichael Ellerman
Currently PPC_CELL_NATIVE selects PPC_OF_PLATFORM_PCI, but does not select PCI. This can lead to a config with the former and the latter disabled, which does not build. To fix this PPC_CELL_NATIVE should select PCI. However, that would force PCI on for QPACE, which also selects PPC_CELL_NATIVE. So instead move the select of PPC_OF_PLATFORM_PCI and PCI under both IBM_CELL_BLADE and CELLEB.

2009-04-28powerpc: ppc32 needs elf_read_implies_exec()Kumar Gala
On ppc64 we implemented elf_read_implies_exec() for 32-bit binaries because old toolchains had bugs where they didn't mark program segments executable that needed to be. For some reason we didn't do this on ppc32 builds. This hadn't been an issue until commit 8d30c14c ("powerpc/mm: Rework I$/D$ coherency (v3)"), which had as a side effect that we are now enforcing execute permissions to some extent on 32-bit 4xx and Book E processors. This fixes it by defining elf_read_implies_exec on 32-bit to turn on the read-implies-exec behaviour on programs that are sufficiently old that they don't have a PT_GNU_STACK program header.

2009-04-27davinci: DM644x: NAND: update partitioningDavid Brownell
Update NAND partitioning for the dm6446 evm, unmasking the hidden data at the beginning and letting the kernel be updated from Linux. - This is boot-compatible with TI's software (U-Boot 1.20 and both the 2.6.10 and 2.6.18 kernels), in terms of startup and loading kernels from flash. - In the same way, it's also boot-compatible with mainline U-Boot, which stores U-Boot params in block 0 not block 16. - It's not quite compatible with systems that previously used NAND partitions to hold (filesystem) data. The compatibilities are a bit different based on which kernel was used previously + Users of TI/MV kernels no longer see mtd2 "params" (mainline u-boot env is in a different place) * Filesystem is now mtd2 ... vs mtd3 + Users of GIT kernels now see mtd0 and mtd1 partitions * Filesystem partition starts 640 KBytes earlier * Filesystem is now mtd2 ... vs mtd0 * Linux now *uses* the flash-resident BBT * Removes annoying slowdown/hiccup during boot * Potentially ~64KB less space available with TI/MV kernels If you *used* NAND partitions from Linux, there is no solution that's fully compatible with all previous kernels in those respects ... ergo this "best compromise". It'd be good to back back up the filesystem data; or, carry your own backwards-compatibility patch for awhile.

2009-04-27davinci: gpio bugfixesDavid Brownell
Update the DaVinci GPIO code to work better on non-dm6446 parts, notably the dm355: - Only handle the number of GPIOs the chip actually has. So for example on dm6467, GPIO-42 is the last GPIO, and trying to use GPIO-43 now fails cleanly; or GPIO-72 on dm6446. - Enable GPIO interrupts on each 16-bit GPIO-irq bank ... previously, only the first five were enabled, so GPIO-80 and above (on dm355) wouldn't trigger IRQs. - Use the right IRQ for each GPIO bank. The wrong values were used for dm355 chips, so GPIO IRQs got routed incorrectly. - Handle up to four pairs of 16-bit GPIO banks ... previously only three were handled, so accessing GPIO-96 and up (e.g. on dm355) would oops. - Update several comments that were dm6446-specific. Verified by receiving GPIO-1 (dm9000) and GPIO-5 (msp430) IRQs on the DM355 EVM. One thing this doesn't do is handle the way some of the GPIO numbers on dm6467 are reserved but aren't valid as GPIOs.
