The current cond_syscall #defines add a semicolon on the end, and then folks leave the semicolons off in kernel/sys_ni.c, which confuses editors that are language-aware and is just generally bad style. This sweeps all the users and makes sys_ni.c look like normal C code. Signed-off-by:

Randy Dunlap found one case where checkstack reported a false positive. From objdump of efi_stub.o: 5: 81 ea 00 00 00 c0 sub $0xc0000000,%edx With the old code, this was interpreted as a negative number. The output line was: 0xc0116f5d efi_call_phys: 1073741824 Randy wanted a change to return the correct number, like this: 0xc0116f5d efi_call_phys: 3221225472 adding "or I can just ignore it, like I've been doing for awhile..." Let's help him with the most sophisticated electronic tools and have the script actively ignore this case for him. Signed-off-by:

This patch pulls together the compat_sigevent structs. It also consolidates the copying of these structures into the kernel. The only part of the second union in sigevent that the kernel looks at currently is the _tid, so that is the only bit we copy. This patch depends on my previous two patches "add and use COMPAT_SIGEV_PAD_SIZE" and "Consolidate the last compat sigvals". Signed-off-by:

This patch just consolidates the last of the (what should have been) compat_sigval_ts. It also fixes S390 that had a sigval_t in its struct compat_siginfo. Signed-off-by:

All the 32 bit architectures (effectively) define SIGEV_PAD_SIZE to be ((SIGEV_MAX_SIZE/sizeof(int)) - 3). So define COMPAT_SIGEV_PAD_SIZE to be this and replace SIGEV_PAD_SIZE32 where it is used. It also needs to be used in the definition of struct compat_sigevent as most of the architectures would have had it 4 bytes too small in the kernel (since we were using SIGEV_PAD_SIZE).

With Andrew Morton invalidate_inode_pages2_range() can livelock if all the pages in the pagevec are outside the end of teh range which we're trying to invalidate. Fix that up in a similar manner to the truncate_inode_pages_range() handling. Signed-off-by:

This is an update of the HFC USB ISDN driver, the current one has some bugs and support not all HW. It was already tested as standalone patch for some time, so including it should be safe. Signed-off-by:

fix_range_common and flush_tlb_kernel_range_common don't work correctly, if a PGD (or PUD or PMD) is not present and start_addr (resp. start) is not aligned to a PGD boundary (or PUD or PMD boundary). Signed-off-by:

This patch merges now-identical page table walking and flushing code that had been duplicated in skas and tt modes. The differences had been the low-level address space updating operations, which are now abstracted away in the respective do_ops functions. Signed-off-by:
-
Jeff Dike authored
This patch optimizes tlb flushing in a couple of ways to reduce the number of system calls made to the host in order to update an address space. Operations are collected, and adjacent ones which can be merged, are. This includes consecutive munmaps, mprotects with the same permissions, and mmaps with the same backing file and permissions and linear in the file. Second, the munmaps that always preceded mmaps are now done instead of mmap if necessary. Signed-off-by:

To quote .config into config.c for building the result into the code, use sed instead of perl, as requested by one "embedded" UML user (which notes that perl is a big requirement, while busybox provides sed which is used in this patch). I've tested that there are only cosmethical differences in the produced config.c file, which don't change at all the result (i.e. "a" is replaced by "" "a" at the beginning, which is non-significant). Reported by, and initial patch provided by, Rob Landley. Signed-off-by:

From: Esben Nielsen <simlo at phys au dk> One of the problems was use of direct architecture specific semaphores (which doesn't work under PREEMPT_REALTIME) and in places where a quick (maybe too quick) look at the code told me that completions ought to be used. Therefore I changed two semaphores to completions which compiled fine. I have tried the change on 2.6.11-rc2, and it seemed to work, but I have not tested it heavily. Signed-off-by:

The init function called by gcc when gcov is enabled is __gcov_init or __bb_init_func, depending on the gcc version. Anton is using 3.3.4 and seeing __gcov_init. I'm using 3.3.2 and seeing __bb_init_func, so we need to close that gap a bit. Signed-off-by:

From: Bodo Stroesser, mostly: Gets rid of all inclusions of {sys,linux,asm}/ptrace.h since their effects and contents are somewhat distro- and architecture-dependent. arch/um/sysdep/ptrace_user is now responsible for providing the system's ptrace interfaces to UML. As such, it is a purely userspace header, and this exposed a couple of places where kernel files were including it. One of them needed MAX_REG_OFFSET, so this was provided by adding a new generated header, user-constants.h, which includes this. Also, changed PTRACE_{PEEK,POKE}_USER to _USR since that seems to be more standard. Signed-off-by: -

Noticed by Frank Sorenson - the methods in arch/um/drivers/tty.c should be static. It turns out that all the channels have the same problem, so these are all fixed. These files export only a structure of function pointers, so that structure should be the only externally visible symbol. Signed-off-by:

This patch adds some errors and warnings where there were none before: If someone typos "ubd" as "udb", that is caught and a warning is printed If a ubd file can't be opened, that now results in an error message If there are more telnet connections to port consoles than there are consoles, then a message will appear in the telnet session explaining why there is no login prompt.

This fixes a couple of copy-user problems spotted by Al Viro. copy_sc_from_user_tt was doing a copy_from_user to do an in-kernel assignment. I commented this, at the request of Chris Wedgewood. sys_ipc had a void *__user ptr which should have been void __user *ptr. Finally, there were a couple of bogus __user annotations on unsigned longs, which were never going to be passed into copy_user. Signed-off-by:

The AMD-8131 I/O APIC (device id 1022:7450/7451) does not support message signalled interrupts. Thus, if a device driver attempts to enable msi, it will suceed, but interrupts are not actually delivered to the cpu. The Nforce chipsets do not seem to have this limitation. AMD confirmed that MSI mode is unsupported with this APIC. The following patch adds a flag to pci quirks to detect this and disable msi. Signed-off-by:
