I no longer work at Bluewater Systems. Update my email address accordingly. I have deleted my email address from C files rather than change it. This was suggested by several people, since the commit from my new email address will cause scripts/get_maintainer.pl to function properly. I have not added the .mailmap entry as suggested by Joe because I think it is no longer necessary if I touch all the files which had my name in them.

During converting per-cpu ticker to genirq layer some IRQ initialization code was removed by commit 2cf9530420e446bb61f665d02afeb81070106900 ("sparc32,leon: per-cpu ticker use genirq per-cpu handler"). This patch reintroduces the code at the same place it was removed from. IRQ12 - IRQ14 will crash on LEON SMP without this patch because it will run the SUN4M IRQ trap handler.

2011-06-09exec: delay address limit change until point of no returnMathias Krause2-2/+0
Unconditionally changing the address limit to USER_DS and not restoring it to its old value in the error path is wrong because it prevents us using kernel memory on repeated calls to this function. This, in fact, breaks the fallback of hard coded paths to the init program from being ever successful if the first candidate fails to load. With this patch applied switching to USER_DS is delayed until the point of no return is reached which makes it possible to have a multi-arch rootfs with one arch specific init binary for each of the (hard coded) probed paths. Since the address limit is already set to USER_DS when start_thread() will be invoked, this redundancy can be safely removed.

2011-06-09powerpc: Force page alignment for initrd reserved memoryBenjamin Herrenschmidt4-32/+43
When using 64K pages with a separate cpio rootfs, U-Boot will align the rootfs on a 4K page boundary. When the memory is reserved, and subsequent early memblock_alloc is called, it will allocate memory between the 64K page alignment and reserved memory. When the reserved memory is subsequently freed, it is done so by pages, causing the early memblock_alloc requests to be re-used, which in my case, caused the device-tree to be clobbered. This patch forces the reserved memory for initrd to be kernel page aligned, and will move the device tree if it overlaps with the range extension of initrd. This patch will also consolidate the identical function free_initrd_mem() from mm/init_32.c, init_64.c to mm/mem.c, and adds the same range extension when freeing initrd. free_initrd_mem() is also moved to the __init section.

2011-06-07MN10300: die_if_no_fixup() shouldn't use get_user() as it doesn't call set_fs()David Howells1-2/+2
die_if_no_fixup() shouldn't use get_user() as it doesn't call set_fs() to indicate that it wants to probe a kernel address. Instead it should use probe_kernel_read(). This fixes the problem of gdb seeing SIGILL rather than SIGTRAP when hitting the KGDB special breakpoint upon SysRq+g being seen. The problem was that die_if_no_fixup() was failing to read the opcode of the instruction that caused the exception, and thus not fixing up the exception. This caused gdb to get a S04 response to the $? request in its remote protocol rather than S05 - which would then cause it to continue with $C04 rather than $c in an attempt to pass the signal onto the inferior process. The kernel, however, does not support $Cnn, and so objects by returning an E22 response, indicating an error. gdb does not expect this and prints: warning: Remote failure reply: E22 and then returns to the gdb command prompt unable to continue.

2011-06-07Do not skip interrupt sources in sun4d interrupt handler and acknowledge ↵oftedal1-9/+5
interrupts correctly During the introduction of genirq on sparc32 bugs were introduced in the interrupt handler for sun4d. The interrupts handler checks the status of the various sbus interfaces in the system and generates a virtual interrupt, based upon the location of the interrupt source. This lookup was broken by restructuring the code in such a way that index and shift operations were performed prior to comparing this against the values read from the interrupt controllers. This could cause the handler to loop eternally as the interrupt source could be skipped before any check was performed. Additionally sun4d_encode_irq performs shifting internally, so it should not be performed twice. In sun4d_unmask interrupts were not correctly acknowledged, as the corresponding bit it the interrupt mask was not actually cleared.

2011-06-07Restructure sun4d_build_device_irq so that timer interrupts can be allocatedoftedal1-24/+54
sun4d_build_device_irq was called without a valid platform_device when the system timer was initialized on sun4d systems. This caused a NULL pointer crash. Josip Rodin suggested that the current sun4d_build_device_irq should be split into two functions. So that the timer initialization could skip the slot and sbus interface detection code in sun4d_build_device_irq, as this does not make sence due to the timer interrupts not being generated from a device located on sbus.

2011-06-06[S390] kvm-s390: fix stfle facilities numbers >=64Christian Borntraeger1-0/+1
Currently KVM masks out the known good facilities only for the first double word, but passed the 2nd double word without filtering.

2011-06-06[S390] kvm-s390: Fix host crash on misbehaving guestsChristian Borntraeger1-0/+2
commit 9ff4cfb3fcfd48b49fdd9be7381b3be340853aa4 ([S390] kvm-390: Let kernel exit SIE instruction on work) fixed a problem of commit commit cd3b70f5d4d82f85d1e1d6e822f38ae098cf7c72 ([S390] virtualization aware cpu measurement) but uncovered another one. If a kvm guest accesses guest real memory that doesnt exist, the page fault handler calls the sie hook, which then rewrites the return psw from sie_inst to either sie_exit or sie_reenter. On return, the page fault handler will then detect the wrong access as a kernel fault causing a kernel oops in sie_reenter or sie_exit. We have to add these two addresses to the exception table to allow graceful exits.

2011-06-06KVM: x86: use proper port value when checking io instruction permissionMarcelo Tosatti1-35/+47
Commit f6511935f42 moved the permission check for io instructions to the ->check_perm callback. It failed to copy the port value from RDX register for string and "in,out ax,dx" instructions. Fix it by reading RDX register at decode stage when appropriate. Fixes FC8.32 installation. Signed-off-by: Marcelo Tosatti <mtosatti@redhat.com>

2011-06-04ARM: Tegra: Harmony: Fix conflicting GPIO numberingStephen Warren2-2/+5
Currently, both the WM8903 and TPS6586x chips attempt to register with gpiolib using the same GPIO numbers. This causes the audio driver to fail to initialize. To solve this, add a define to board-harmony.h for the TPS6586x, and make board-harmony-power.c use this define, instead of directly referencing TEGRA_NR_GPIOS. This fixes a regression introduced by commit 6f168f2fa60f87e85e0df25e87e2372f22f5eb7c.

The jump to 4f will cause the NUL padding loop to run at least one time, so if string length is zero just jump to the end. Otherwise we wrongly write one NUL byte when size==0. Signed-off-by: Steven Miao <realmz6@gmail.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
