2007-08-15[POWERPC] Fix for assembler -gRoland McGrath
ppc64 does the unusual thing of using #include on a compiler-generated assembly file (lparmap.s) from an assembly source file (head_64.S). This runs afoul of my recent patch to pass -gdwarf2 to the assembler under CONFIG_DEBUG_INFO. This patch avoids the problem by disabling DWARF generation (-g0) when producing lparmap.s.

2007-08-15[POWERPC] Fix small race in 44x tlbie functionDavid Gibson
The 440 family of processors don't have a tlbie instruction. So, we implement TLB invalidates by explicitly searching the TLB with tlbsx., then clobbering the relevant entry, if any. Unfortunately the PID for the search needs to be stored in the MMUCR register, which is also used by the TLB miss handler. Interrupts were enabled in _tlbie(), so an interrupt between loading the MMUCR and the tlbsx could cause incorrect search results, and thus a failure to invalide TLB entries which needed to be invalidated. This fixes the problem in both arch/ppc and arch/powerpc by inhibiting interrupts (even critical and debug interrupts) across the relevant instructions.

2007-08-15[POWERPC] Remove unused code causing a compile warningBecky Bruce
AFAICT, nobody is using ft_ordered(), and it causes a build warning to be generated. This patch cleans that up by removing the function and the commented-out code that calls it.

2007-08-15[POWERPC] cell: Fix errno for modular spufs_create with invalid neighbourJeremy Kerr
At present, spu_create with an invalid neighbo(u)r will return -ENOSYS, not -EBADF, but only when spufs.o is built as a module. This change adds the appropriate errno, making the behaviour the same as the built-in case.

2007-08-14[SPARC32]: Remove superfluous 'kernel_end' alignment on sun4c.Mark Fortescue
In sun4c_init_clean_mmu(), aligning 'kernel_end' using SUN4C_REAL_PGDIR_ALIGN() is unnecessary since the caller does this already. In sun4c_paging_init(), 4 page sizes of "fluff" were added to the address of &end. This was necessary a long time ago when sparc32 would allocate some early data structures by carving out memory chunks after &end but that no longer occurs.

2007-08-14[x86 setup] edd.c: make sure MBR signatures actually get reportedH. Peter Anvin

2007-08-14[x86 setup] Don't use EDD to get the MBR signatureH. Peter Anvin
At least one machine has been identified in the field which advertises EDD for all drives but locks up if one attempts an extended read from a non-primary drive. The MBR is always at CHS 0-0-1, so there is no reason to use an extended read, other than the possibility that the BIOS cannot handle it. Although this might break as many machines as it fixes (a small number either way), the current state is a regression but the reverse is not. Therefore revert to the previous state of not using extended read. Quite probably the Right Thing to do is to read using plain (CHS) read and extended read on failure, but that change would definitely have to go through -mm first. Signed-off-by: H.

2007-08-14[IOAT]: Remove redundant struct member to avoid descriptor cache missShannon Nelson
The layout for struct ioat_desc_sw is non-optimal and causes an extra cache hit for every descriptor processed. By tightening up the struct layout and removing one item, we pull in the fields that get used in the speedpath and get a little better performance. Before: ------- struct ioat_desc_sw { struct ioat_dma_descriptor * hw; /* 0 8 */ struct list_head node; /* 8 16 */ int tx_cnt; /* 24 4 */ /* XXX 4 bytes hole, try to pack */ dma_addr_t src; /* 32 8 */ __u32 src_len; /* 40 4 */ /* XXX 4 bytes hole, try to pack */ dma_addr_t dst; /* 48 8 */ __u32 dst_len; /* 56 4 */ /* XXX 4 bytes hole, try to pack */ /* --- cacheline 1 boundary (64 bytes) --- */ struct dma_async_tx_descriptor async_tx; /* 64 144 */ /* --- cacheline 3 boundary (192 bytes) was 16 bytes ago --- */ /* size: 208, cachelines: 4 */ /* sum members: 196, holes: 3, sum holes: 12 */ /* last cacheline: 16 bytes */ }; /* definitions: 1 */ After: ------ struct ioat_desc_sw { struct ioat_dma_descriptor * hw; /* 0 8 */ struct list_head node; /* 8 16 */ int tx_cnt; /* 24 4 */ __u32 len; /* 28 4 */ dma_addr_t src; /* 32 8 */ dma_addr_t dst; /* 40 8 */ struct dma_async_tx_descriptor async_tx; /* 48 144 */ /* --- cacheline 3 boundary (192 bytes) --- */ /* size: 192, cachelines: 3 */ }; /* definitions: 1 */ Signed-off-by: Shannon Nelson <shannon.nelson@intel.com> Signed-off-by: David S.

This stems from our need to have the one bit in the ioctl attr flags mean two different things according to whether the underlying inode is a directory or not.

The error path in prepare_write() was incorrect in the (very rare) event that the transaction fails to start. The following prevents a NULL pointer dereference, Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>
2007-08-14[GFS2] Fix incorrect return code in rgrp.cSteven Whitehouse
The following patch fixes a bug where 0 was being used as a return code to indicate "nothing to do" when in fact 0 was a valid block location which might be returned by the function. Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>
2007-08-14[GFS2] soft lockup in rgblk_searchBob Peterson
This patch seems to fix the problem described in bugzilla bug 246114. It was written by Steve Whitehouse with some tweaking by me. The code was looping in the relatively new section of code designed to search for and reuse unlinked inodes. In cases where it was finding an appropriate inode to reuse, it was looping around and finding the same block over and over because a "<=" check should have been a "<" when comparing the goal block to the last unlinked block found.

2007-08-14[GFS2] soft lockup detected in databuf_lo_before_commitBob Peterson
This is part 2 of the patch for bug #245832, part 1 of which is already in the git tree. The problem was that sdp->sd_log_num_databuf was not always being protected by the gfs2_log_lock spinlock, but the sd_log_le_databuf (which it is supposed to reflect) was protected. That meant there was a timing window during which gfs2_log_flush called databuf_lo_before_commit and the count didn't match what was really on the linked list in that window. So when it ran out of items on the linked list, it decremented total_dbuf from 0 to -1 and thus never left the "while(total_dbuf)" loop. The solution is to protect the variable sdp->sd_log_num_databuf so that the value will always match the contents of the linked list, and therefore the number will never go negative, and therefore, the loop will be exited properly.

2007-08-14[DLM] fix basts for granted PR waiting CWDavid Teigland
Fix a long standing bug where a blocking callback would be missed when there's a granted lock in PR mode and waiting locks in both PR and CW modes (and the PR lock was added to the waiting queue before the CW lock). The logic simply compared the numerical values of the modes to determine if a blocking callback was required, but in the one case of PR and CW, the lower valued CW mode blocks the higher valued PR mode. We just need to add a special check for this PR/CW case in the tests that decide when a blocking callback is needed.

2007-08-14[DLM] Fix memory leak in dlm_add_member() when dlm_node_weight() returns ↵Jesper Juhl
less than zero There's a memory leak in fs/dlm/member.c::dlm_add_member(). If "dlm_node_weight(ls->ls_name, nodeid)" returns < 0, then we'll return without freeing the memory allocated to the (at that point yet unused) 'memb'. This patch frees the allocated memory in that case and thus avoids the leak.
