2009-12-14udf: Avoid IO in udf_clear_inodeJan Kara3-22/+41
It is not very good to do IO in udf_clear_inode. First, VFS does not really expect inode to become dirty there and thus we have to write it ourselves, second, memory reclaim gets blocked waiting for IO when it does not really expect it, third, the IO pattern (e.g. on umount) resulting from writes in udf_clear_inode is bad and it slows down writing a lot. The reason why UDF needed to do IO in udf_clear_inode is that UDF standard mandates extent length to exactly match inode size. But when we allocate extents to a file or directory, we don't really know what exactly the final file size will be and thus temporarily set it to block boundary and later truncate it to exact length in udf_clear_inode. Now, this is changed to truncate to final file size in udf_release_file for regular files. For directories and symlinks, we do the truncation at the moment when learn what the final file size will be. Signed-off-by: Jan Kara <jack@suse.cz>
2009-12-14udf: Try harder when looking for VAT inodeJan Kara1-8/+24
Some disks do not contain VAT inode in the last recorded block as required by the standard but a few blocks earlier (or the number of recorded blocks is wrong). So look for the VAT inode a bit before the end of the media. Signed-off-by: Jan Kara <jack@suse.cz>

2009-12-14x86, mce: Thermal monitoring depends on APIC being enabledCyrill Gorcunov1-2/+3
Add check if APIC is not disabled since thermal monitoring depends on it. As only apic gets disabled we should not try to install "thermal monitor" vector, print out that thermal monitoring is enabled and etc... Note that "Intel Correct Machine Check Interrupts" already has such a check. Also I decided to not add cpu_has_apic check into mcheck_intel_therm_init since even if it'll call apic_read on disabled apic -- it's safe here and allow us to save a few code bytes.

This fixes the following breakage of the commit 75f1cdf1dda92cae037ec848ae63690d91913eac: - GART systems that don't AGP with broken BIOS and more than 4GB memory are forced to use swiotlb. They can allocate aperture by hand and use GART. - GART systems without GAP must disable GART on shutdown. - swiotlb usage is forced by the boot option, gart_iommu_hole_init() is not called, so we disable GART early_gart_iommu_check().

WB cache has special flag in PVR. There is added checking mechanism for PVR and DTS. Signed-off-by: Michal Simek <monstr@monstr.eu>
2009-12-14microblaze: Remove duplicity from pgalloc.hMichal Simek1-6/+3
just file cleanup Signed-off-by: Michal Simek <monstr@monstr.eu>
2009-12-14microblaze: Futex supportMichal Simek1-1/+126
Microblaze v7.20 provides new lwx, swx instructions which bring possibility to implement lock rutines. There are some tests in open posix thread LTP part but current toolchain not support it. Signed-off-by: Michal Simek <monstr@monstr.eu>
2009-12-14microblaze: Adding dev_arch_data functionsMichal Simek1-0/+12
The functions, dev_arch_data_set_node and get_node are missing and are needed by some device drivers such as I2C. Signed-off-by: John Linn <john.linn@xilinx.com> Signed-off-by: Michal Simek <monstr@monstr.eu>
2009-12-14microblaze: Fix the heartbeat gpio to be more robustJohn Linn1-5/+10
The device tree handling for the gpio in the heart beat was not handling the system when there was no gpio and it wasn't working with a newer version of the gpio core which does not have the is-bidir property.

2009-12-14microblaze: Simple __copy_tofrom_user for noMMUJohn Williams2-6/+13
This is first patch which clear part of uaccess.h. uaccess.h will be clear later. Signed-off-by: John Williams <john.williams@petalogix.com> Signed-off-by: Michal Simek <monstr@monstr.eu>
2009-12-14microblaze: Export memory_start for modulesMichal Simek1-0/+1
memory_start symbol is needed by kernel modules. Signed-off-by: Michal Simek <monstr@monstr.eu>
2009-12-14microblaze: Use lowest-common-denominator default CPU settingsJohn Williams1-6/+6
This will ensure that kernels built with no custom CPU settings will still boot OK on hardware that has additional CPU hardware instructions etc. Signed-off-by: John Williams <john.williams@petalogix.com> Signed-off-by: Michal Simek <monstr@monstr.eu>
2009-12-14microblaze: Update default generic DTSMichal Simek1-3/+7
It is generated with longer compatible list Signed-off-by: Michal Simek <monstr@monstr.eu>
2009-12-14microblaze: Enable asm optimization only for HW with barrel-shifterMichal Simek1-1/+1
Asm code uses barrel-shifter instruction that's why we have to protect cases when HW don't have it. Reported-by: John Linn <john.linn@xilinx.com> Signed-off-by: Michal Simek <monstr@monstr.eu>
2009-12-14microblaze: Remove the buggy ALLOW_EDIT_AUTO config optionJohn Williams2-28/+8
This was intended to allow manual override of CPU settings copied automatically to Kconfig.auto, however it's problematic for several reasons, but mostly: * If the defconfig doesn't have ALLOW_EDIT_AUTO=y, then it's impossible for that defconfig to iverride the values in the kernel source tree. This leads to very strange errors where the kernel is compiled with the wrong CPUFLAGS. Next patch in the series will back out the default in Kconfig.auto to baseline settings, so a kernel built with no default values will at least boot on any hardware, just not make use of additional CPU features.
