2007-02-07[POWERPC] Fix kernel build errors for mpc8272ads and mpc8560adsVitaly Bordug2-0/+12
Recent update of asm-powerpc/io.h caused cpm-related stuff to break in the current kernel. Current patch fixes it, as well as other inconsistencies expressed, that do not permit targets from working properly: - Updated dts with a chosen node with interrupt controller, - fixed messed device IDs among CPM2 SoC devices, - corrected odd header name and fixed type in defines, - Added 82xx subdir to the powerpc/platforms Makefile, missed during initial commit, - new solely-powerpc header file for 8260 family (was using one from arch/ppc, this one cleaned up from the extra stuff), in fact for now a placeholder to get the board-specific includes for stuff not yet capable to live with devicetree peeks only - Fixed couple of misprints in reference mpc8272 dts.

2007-02-07[POWERPC] cpm2: CPM2 interrupt controller fixVitaly Bordug1-0/+24
This contains important fixes for the CPM2 PIC code. Eliminated CPM_IRQ_OFFSET, pulling the respective interrupt numbers from the interrupt mapping. Updated devicetree files to reflect that. Changed direct IC-related IO accesses to the IO accessors. Fixed all the sense values to keep coherency with ipic. In the current code, CPM2 stuff will have no IRQs and hence could be hardly usable.

2007-01-24[POWERPC] Move ELF_ET_DYN_BASE up to 512MB pointAnton Blanchard1-1/+1
I often test new versions of glibc by doing: LD_LIBRARY_PATH=/XXX/lib /XXX/lib/ld.so.1 <binary> One test case ended up SEGV'ing. Upon closer inspection ld.so was loaded at 0x8000000 (128MB) with the heap right after it. Since we normally link binaries at 0x10000000 (256MB) we only had about 128MB of space for the heap: 00100000-00103000 r-xp 00100000 00:00 0 [vdso] 08000000-0801e000 r-xp 00000000 00:01 33079 /lib/ld-2.5.so 0802d000-0802f000 rwxp 0001d000 00:01 33079 /lib/ld-2.5.so 0802f000-08050000 rwxp 0802f000 00:00 0 [heap] 0fe91000-0ffd9000 r-xp 00000000 00:01 33082 /lib/libc-2.5.so 0ffd9000-0ffe8000 ---p 00148000 00:01 33082 /lib/libc-2.5.so 0ffe8000-0ffea000 r--p 00147000 00:01 33082 /lib/libc-2.5.so 0ffea000-0ffed000 rwxp 00149000 00:01 33082 /lib/libc-2.5.so 10000000-10004000 r-xp 00000000 00:01 76 /bin/sleep 10013000-10014000 rwxp 00003000 00:01 76 /bin/sleep ffb41000-ffb56000 rw-p ffb41000 00:00 0 [stack] One way to fix this is move ELF_ET_DYN_BASE from 0x08000000 to 0x20000000. This allows 128MB for the binary (hopefully enough for even the most crazy c++ apps), and with our current layout we will grow the heap up and the stack down, allowing potentially gigabytes of heap: 00100000-00103000 r-xp 00100000 00:00 0 [vdso] 0fe8a000-0ffd3000 r-xp 00000000 00:01 3350 /lib/tls/libc-2.3.6.so 0ffd3000-0ffe3000 ---p 00149000 00:01 3350 /lib/tls/libc-2.3.6.so 0ffe3000-0ffea000 r--p 00149000 00:01 3350 /lib/tls/libc-2.3.6.so 0ffea000-0ffee000 rwxp 00150000 00:01 3350 /lib/tls/libc-2.3.6.so 10000000-10004000 r-xp 00000000 00:01 76 /bin/sleep 10013000-10014000 rwxp 00003000 00:01 76 /bin/sleep 20000000-20018000 r-xp 00000000 00:01 3478 /lib/ld-2.3.6.so 20028000-20029000 r--p 00018000 00:01 3478 /lib/ld-2.3.6.so 20029000-2002a000 rwxp 00019000 00:01 3478 /lib/ld-2.3.6.so 2002a000-2004b000 rwxp 2002a000 00:00 0 [heap] ffd67000-ffd7c000 rw-p ffd67000 00:00 0 [stack] Signed-off-by: Anton Blanchard <anton@samba.org> Signed-off-by: Paul Mackerras <paulus@samba.org>
2007-01-23[PATCH] x86: fix PDA variables to work during bootJames Bottomley1-0/+1
The current PDA code, which went in in post 2.6.19 has a flaw in that it doesn't correctly cycle the GDT and %GS segment through the boot PDA, the CPU PDA and finally the per-cpu PDA. The bug generally doesn't show up if the boot CPU id is zero, but everything falls apart for a non zero boot CPU id. The basically kills voyager which is perfectly capable of doing non zero CPU id boots, so voyager currently won't boot without this. The fix is to be careful and actually do the GDT setups correctly.

2007-01-22[POWERPC] atomic_dec_if_positive sign extension fixRobert Jennings1-3/+5
On 64-bit machines, if an atomic counter is explicitly set to a negative value, the atomic_dec_if_positive function will decrement and store the next smallest value in the atomic counter, contrary to its intended operation. The comparison to determine if the decrement will make the result negative was done by the "addic." instruction, which operates on a 64-bit value, namely the zero-extended word loaded from the atomic variable. This patch uses an explicit word compare (cmpwi) and changes the addic. to an addi (also changing "=&r" to "=&b" so that r0 isn't used, and addi doesn't become li). This also fixes a bug for both 32-bit and 64-bit in that previously 0x80000000 was considered positive, since the result after decrementing is positive. Now it is considered negative. Also, I clarify the return value in the comments just to make it clear that the value returned is always the decremented value, even if that value is not stored back to the atomic counter.

2007-01-20libata: initialize qc->dma_dir to DMA_NONETejun Heo1-0/+1
libata didn't used to init qc->dma_dir to any specific value on qc initialization and command translation path didn't set qc->dma_dir if the command doesn't need data transfer. This made non-data commands to have random qc->dma_dir. This usually doesn't cause problem because LLDs usually check qc->protocol first and look at qc->dma_dir iff the command needs data transfer but this doesn't hold for all LLDs. It might be worthwhile to rename qc->dma_dir to qc->data_dir as we use the field to tag data direction for both PIO and DMA protocols. This problem has been spotted by James Bottomley.

2007-01-12[PATCH] NFS: Fix race in nfs_release_page()Trond Myklebust1-0/+1
NFS: Fix race in nfs_release_page() invalidate_inode_pages2() may find the dirty bit has been set on a page owing to the fact that the page may still be mapped after it was locked. Only after the call to unmap_mapping_range() are we sure that the page can no longer be dirtied. In order to fix this, NFS has hooked the releasepage() method and tries to write the page out between the call to unmap_mapping_range() and the call to remove_mapping(). This, however leads to deadlocks in the page reclaim code, where the page may be locked without holding a reference to the inode or dentry. Fix is to add a new address_space_operation, launder_page(), which will attempt to write out a dirty page without releasing the page lock.

2007-01-12[PATCH] Fix sparsemem on CellDave Hansen2-3/+8
Fix an oops experienced on the Cell architecture when init-time functions, early_*(), are called at runtime. It alters the call paths to make sure that the callers explicitly say whether the call is being made on behalf of a hotplug even, or happening at boot-time. It has been compile tested on ppc64, ia64, s390, i386 and x86_64.
