Revert part of af5c820a ("x86: cpumask: use work_on_cpu in arch/x86/kernel/microcode_core.c") That change is causing only one Intel CPU's microcode to be updated e.g. microcode: CPU3 updated from revision 0x9 to 0x17, date = 2005-04-22 where before it announced that also for CPU0 and CPU1 and CPU2. We cannot use work_on_cpu() in the CONFIG_MICROCODE_OLD_INTERFACE code, because Intel's request_microcode_user() involves a copy_from_user() from /sbin/microcode_ctl, which therefore needs to be on that CPU at the time.

Fix lpfc_parse_bg_err()'s use of do_div(). It should be passing a 64-bit variable as the first parameter. However, since it's only using a 32-bit variable, it doesn't need to use do_div() at all, but can instead use the division operator. This deals with the following warnings: CC drivers/scsi/lpfc/lpfc_scsi.o drivers/scsi/lpfc/lpfc_scsi.c: In function 'lpfc_parse_bg_err': drivers/scsi/lpfc/lpfc_scsi.c:1397: warning: comparison of distinct pointer types lacks a cast drivers/scsi/lpfc/lpfc_scsi.c:1397: warning: right shift count >= width of type drivers/scsi/lpfc/lpfc_scsi.c:1397: warning: passing argument 1 of '__div64_32' from incompatible pointer type Signed-off-by:David Howells <dhowells@redhat.com> Signed-off-by:

In commit 51dcdfec ("parport: Use the PCI IRQ if offered") parport_pc_probe_port() gained an irqflags arg. This isn't being supplied on powerpc.

If the ti-usb adapter returns an zero data length frame (which happens) then we leak a kref. Found by Christoph Mair <christoph.mair@gmail.com> who proposed a patch. The patch here is different as Christoph's patch didn't work for the case where tty = NULL and data arrived but Christoph did all the hard work chasing it down. Signed-off-by:

ACM sets the low latency flag but calls the flip buffer routines from IRQ context which isn't permitted (and as of 2.6.29 causes a warning hence this one was caught) Fortunatelt ACM doesn't need to set this flag in the first place as it only set it to work around problems in ancient (pre tty flip rewrite) kernels.

Impact: build fix for Sparc and s390 Stephen Rothwell reported that the Sparc build broke: In file included from kernel/panic.c:12: include/linux/debug_locks.h: In function '__debug_locks_off': include/linux/debug_locks.h:15: error: implicit declaration of function 'xchg' due to: 9eeba613: lockdep: warn about lockdep disabling after kernel taint There is some inconsistency between architectures about where exactly xchg() is defined. The traditional place is in system.h but the more logical point for it is in atomic.h - where most architectures (especially new ones) have it defined. These architecture also still offer it via system.h. Some, such as Sparc or s390 only have it in asm/system.h and not available via asm/atomic.h at all. Use the widest set of headers in debug_locks.h and also include asm/system.h. Reported-by:

We ended up incorrectly using '&cur' instead of '&readin' in the work_on_cpu() -> smp_call_function_single() transformation in commit 01599fca ("cpufreq: use smp_call_function_[single|many]() in acpi-cpufreq.c"). Andrew explains: "OK, the acpi tree went and had conflicting changes merged into it after I'd written the patch and it appears that I incorrectly reverted part of 18b2646f while fixing the resulting rejects. Switching it to `readin' looks correct." Acked-by:

This corrects a race with the PHY RST bit not being set properly if the PLL status changes right before timeout. This resulted in it potentially failing even if the device came up in time. Special thanks to Mr. Juha Leppanen and Iwamatsu-san for reporting this out and reviewing it. Reported-by:

The edac-core driver includes code which assumes that the work_struct which is included in every delayed_work is the first member of that structure. This is currently the case but might change in the future, so use to_delayed_work() instead, which doesn't make such an assumption. linux-2.6.30-rc1 has the to_delayed_work() function that will allow this patch to work Signed-off-by:

If two writers allocating blocks to file race with each other (e.g. because writepages races with ordinary write or two writepages race with each other), ext2_getblock() can be called on the same inode in parallel. Before we are going to allocate new blocks, we have to recheck the block chain we have obtained so far without holding truncate_mutex. Otherwise we could overwrite the indirect block pointer set by the other writer leading to data loss. The below test program by Ying is able to reproduce the data loss with ext2 on in BRD in a few minutes if the machine is under memory pressure: long kMemSize = 50 << 20; int kPageSize = 4096; int main(int argc, char **argv) { int status; int count = 0; int i; char *fname = "/mnt/test.mmap"; char *mem; unlink(fname); int fd = open(fname, O_CREAT | O_EXCL | O_RDWR, 0600); status = ftruncate(fd, kMemSize); mem = mmap(0, kMemSize, PROT_READ | PROT_WRITE, MAP_SHARED, fd, 0); // Fill the memory with 1s. memset(mem, 1, kMemSize); sleep(2); for (i = 0; i < kMemSize; i++) { int byte_good = mem[i] != 0; if (!byte_good && ((i % kPageSize) == 0)) { //printf("%d ", i / kPageSize); count++; } } munmap(mem, kMemSize); close(fd); unlink(fname); if (count > 0) { printf("Running %d bad page\n", count); return 1; } return 0; } Cc: Ying Han <yinghan@google.com> Cc: Nick Piggin <nickpiggin@yahoo.com.au> Signed-off-by:Jan Kara <jack@suse.cz> Cc: Mingming Cao <cmm@us.ibm.com> Cc: <linux-ext4@vger.kernel.org> Signed-off-by:

SHMEM_MAX_BYTES was derived from the maximum size of its triple-indirect swap vector, forgetting to take the MAX_LFS_FILESIZE limit into account. Never mind 256kB pages, even 8kB pages on 32-bit kernels allowed files to grow slightly bigger than that supposed maximum. Fix this by using the min of both (at build time not run time). And it happens that this calculation is good as far as 8MB pages on 32-bit or 16MB pages on 64-bit: though SHMSWP_MAX_INDEX gets truncated before that, it's truncated to such large numbers that we don't need to care.

Fix a division by zero which we have in shmem_truncate_range() and shmem_unuse_inode() when using big PAGE_SIZE values (e.g. 256kB on ppc44x). With 256kB PAGE_SIZE, the ENTRIES_PER_PAGEPAGE constant becomes too large (0x1.0000.0000) on a 32-bit kernel, so this patch just changes its type from 'unsigned long' to 'unsigned long long'. Hugh: reverted its unsigned long longs in shmem_truncate_range() and shmem_getpage(): the pagecache index cannot be more than an unsigned long, so the divisions by zero occurred in unreached code. It's a pity we need any ULL arithmetic here, but I found no pretty way to avoid it. Signed-off-by:
