Remove the hlist_for_each_rcu() API, which is used only in one place, and is trivially converted to hlist_for_each_entry_rcu(), making the code shorter and more readable. Any out-of-tree uses may be similarly converted. Signed-off-by:

This patch adds a connector that reports fork, exec, id change, and exit events for all processes to userspace. It replaces the fork_advisor patch that ELSA is currently using. Applications that may find these events useful include accounting/auditing (e.g. ELSA), system activity monitoring (e.g. top), security, and resource management (e.g. CKRM). Signed-off-by:

If the backing_dev_info doesn't have BDI_CAP_NO_WRITEBACK we're not supposed to write back an inode's pages. But in this situation write_inode_now() refuses to write the inode itself as well. Fix. Signed-off-by:

Andrew Morton suggested to move kprobes from kernel hacking menu, since kernel hacking menu is in-appropriate for the Kprobes. This patch moves Kprobes and Oprofile under instrumentation menu. (akpm: it's not a natural fit, but things like djprobes and the s390 guys' statistics library need a home) Signed-of-by:

Access to FBA disks via DIAG fails for block sizes > 512 byte. The device analysis code of the DIAG discipline does not properly initialize the DIAG250 device environment after completion of the analysis. This results in VM only serving 512 bytes per block I/O request whereas Linux expects larger block sizes. Add proper device environment setup to end of analysis code. Signed-off-by:

The test_bit function returns a non-boolean value, it returns 0,1,2,4,... instead of only 0 or 1. This causes wrongs results in the mincore system call. Check against 0 to get a proper boolean value. Signed-off-by:

Remove pagex pseudo page fault code. It does not work together with the system call speedup that makes the complete system call path enabled for interrupts. To make pagex and the syscall speedup code work together we would have to add code to the program check handler to do a critical section cleanup like the asynchronous interrupt code. This would make program checks slower. Not what we want. Newer versions of z/VM have the improved pfault pseudo page fault interface. This replaces the old pagex interface and does not have the problem. So its better to just rip out the pagex code. Signed-off-by:

This patch reverts back the changes to HOSTCFLAGS and HOSTLDFLAGS When we were building complete binaries to get constants (such as ptrace register layout on stack) from host userspace headers, we needed to make the arch for building HOST binaries match our one: i.e. on a 64bit system compiling 32bit binaries, we compile 32-bit hostprogs and need, say, 32-bit ncurses. Now we can revert that - that avoids problem with, say, menuconfig and ncurses, on a system which can't compile well 32-bit programs. Signed-off-by:

Remove usage of hardcoded constants in paging_init(). By chance I spotted a bug in zones_setup involving a change to ZONE_* constants, due to the ZONE_DMA32 patch from Andi Kleen (which is in -mm). So, possibly, instead of zones_size[2] you will find zones_size[3] in the code, but that change is wrong and this patch is still correct. Signed-off-by:

Patch imlements full LDT handling in SKAS: * UML holds it's own LDT table, used to deliver data on modify_ldt(READ) * UML disables the default_ldt, inherited from the host (SKAS3) or resets LDT entries, set by host's clib and inherited in SKAS0 * A new global variable skas_needs_stub is inserted, that can be used to decide, whether stub-pages must be supported or not. * Uses the syscall-stub to replace missing PTRACE_LDT (therefore, write_ldt_entry needs to be modified) Signed-off-by:

Not quite, something along the lines of the patch below works correctly (and makes aio performance not suffer from multiple second delays), as skas0 mode correctly switches mm contexts, unlike TT (which should probably get nuked from the kernel now that skas0 seems to be working). Signed-off-by:

ifa->ifa_address and ifa->ifa_mask are defined as __u32, but used as if they were char[4]. Network code uses htons() to convert it. So UML's method to access these fields is wrong for bigendians (e.g. s390) I replaced bytewise copying by memcpy(), maybe even that might be removed, if ifa->ifa_address/mask may be used immediately.

Jeff Dike noted that the assembly code for syscall stubs is misassembled with GCC 3.2.3: the values copied in registers weren't preserved between one asm() and the following one. So I fixed the thing by rewriting the __asm__ constraints more like unistd.h ones. Note: in syscall6 case I had to add one more instruction (i.e. moving arg6 in eax and shuffling things around) - it's needed for the function to be valid in general (we can't load the value from the stack, relative to ebp, because we change it), but could be avoided since we actually use a constant as param 6. The only fix would be to turn stub_syscall6 to a macro and use a "i" constraint for arg6 (i.e., specify it's a constant value). Signed-off-by:
