2010-12-09ARM: 6482/2: Fix find_next_zero_bit and related assemblyJames Jones
commit 0e91ec0c06d2cd15071a6021c94840a50e6671aa upstream. The find_next_bit, find_first_bit, find_next_zero_bit and find_first_zero_bit functions were not properly clamping to the maxbit argument at the bit level. They were instead only checking maxbit at the byte level. To fix this, add a compare and a conditional move instruction to the end of the common bit-within-the- byte code used by all the functions and be sure not to clobber the maxbit argument before it is used.

2010-12-09ARM: 6489/1: thumb2: fix incorrect optimisation in usraccWill Deacon
commit 1142b71d85894dcff1466dd6c871ea3c89e0352c upstream. Commit 8b592783 added a Thumb-2 variant of usracc which, when it is called with \rept=2, calls usraccoff once with an offset of 0 and secondly with a hard-coded offset of 4 in order to avoid incrementing the pointer again. If \inc != 4 then we will store the data to the wrong offset from \ptr. Luckily, the only caller that passes \rept=2 to this function is __clear_user so we haven't been actively corrupting user data. This patch fixes usracc to pass \inc instead of #4 to usraccoff when it is called a second time.

2010-09-20arm: fix really nasty sigreturn bugAl Viro
commit 653d48b22166db2d8b1515ebe6f9f0f7c95dfc86 upstream. If a signal hits us outside of a syscall and another gets delivered when we are in sigreturn (e.g. because it had been in sa_mask for the first one and got sent to us while we'd been in the first handler), we have a chance of returning from the second handler to location one insn prior to where we ought to return. If r0 happens to contain -513 (-ERESTARTNOINTR), sigreturn will get confused into doing restart syscall song and dance. Incredible joy to debug, since it manifests as random, infrequent and very hard to reproduce double execution of instructions in userland code... The fix is simple - mark it "don't bother with restarts" in wrapper, i.e. set r8 to 0 in sys_sigreturn and sys_rt_sigreturn wrappers, suppressing the syscall restart handling on return from these guys. They can't legitimately return a restart-worthy error anyway. Testcase: #include <unistd.h> #include <signal.h> #include <stdlib.h> #include <sys/time.h> #include <errno.h> void f(int n) { __asm__ __volatile__( "ldr r0, [%0]\n" "b 1f\n" "b 2f\n" "1:b .\n" "2:\n" : : "r"(&n)); } void handler1(int sig) { } void handler2(int sig) { raise(1); } void handler3(int sig) { exit(0); } main() { struct sigaction s = {.sa_handler = handler2}; struct itimerval t1 = { .it_value = {1} }; struct itimerval t2 = { .it_value = {2} }; signal(1, handler1); sigemptyset(&s.sa_mask); sigaddset(&s.sa_mask, 1); sigaction(SIGALRM, &s, NULL); signal(SIGVTALRM, handler3); setitimer(ITIMER_REAL, &t1, NULL); setitimer(ITIMER_VIRTUAL, &t2, NULL); f(-513); /* -ERESTARTNOINTR */ write(1, "buggered\n", 9); return 1; } Signed-off-by: Al Viro <viro@zeniv.linux.org.uk> Acked-by: Russell King <rmk+kernel@arm.linux.org.uk> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

faulty ASID commit cdf357f1e13a08a11261edacb3083746f65c1ed9 upstream. On versions of the Cortex-A9 prior to r2p0, performing TLB invalidations by ASID match can result in the incorrect ASID being broadcast to other CPUs. As a consequence of this, the targetted TLB entries are not invalidated across the system. This workaround changes the TLB flushing routines to invalidate entries regardless of the ASID.

commit 3fea60261e73dbf4a51130d40cafcc8465b0f2c3 upstream. The Nokia RX51 board code (arch/arm/mach-omap2/board-rx51-peripherals.c) defines a key map for the matrix keypad keyboard. The hardware seems to use all of the 8 rows and 8 columns of the keypad, although not all possible locations are used. The TWL4030 supports keypads with at most 8 rows and 8 columns. Most keys are defined with a row and column number between 0 and 7, except KEY(0xff, 2, KEY_F9), KEY(0xff, 4, KEY_F10), KEY(0xff, 5, KEY_F11), which represent keycodes that should be emitted when entire row is connected to the ground. since the driver handles this case as if we had an extra column in the key matrix. Unfortunately we do not allocate enough space and end up owerwriting some random memory.

commit 3defb2476166445982a90c12d33f8947e75476c4 upstream. This patch reorganises the sa1111_resume() function in a manner the spinlock happens after calling the sa1111_wake(). This fixes two bugs: 1) This function called sa1111_wake() which tried to claim the same spinlock the sa1111_resume() already claimed. This would result in certain deadlock. Original idea for this part: Russell King <rmk+kernel@arm.linux.org.uk> 2) The function didn't unlock the spinlock in case the chip didn't report correct ID.

commit 9a40ac86152c9cffd3dca482a15ddf9a8c5716b3 upstream. When functions incoming parameters are not in input operands list gcc 4.5 does not load the parameters into registers before calling this function but the inline assembly assumes valid addresses inside this function. This breaks the code because r0 and r1 are invalid when execution enters v4wb_copy_user_page () Also the constant needs to be used as third input operand so account for that as well.

commit 98e12b5a6e05413420a7e3b3eca7fbfc2ff41b6d upstream. Commit 2552fc2 changed the way the decompressor decides if it is safe to decompress the kernel directly to its final location. Unfortunately, it took the top of the compressed data as being the stack pointer, which it is for ROM=n cases. However, for ROM=y, the stack pointer is not relevant, and results in the wrong answer. Fix this by explicitly storing the end of the biggybacked data in the decompressor, and use that to calculate the compressed image size.

2009-11-17[ARM] pxa/hx4700: fix hx4700 touchscreen pressure valuesPaul Parsons
hx4700 touchscreen events were being dropped in ads7846_rx() because their pressure values consistently exceeded the platform maximum of 512; a sample of 256 pressure values were in the range 531 to 815. Doubling the platform maximum to 1024 allows hx4700 touchscreen events to pass the test. Signed-off-by: Paul Parsons <lost.distance@yahoo.com> Signed-off-by: Eric Miao <eric.y.miao@gmail.com>

2009-11-16ARM: 5787/1: U300 COH 901 331 fixesLinus Walleij
This will fix some small issues with the COH 901 331 RTC driver: - Interrupt is disabled after alarm so that we don't fire multiple interrupts. - We return 0 from the coh901331_alarm_irq_enable() ridding a compile warning. - We alter the name in the U300 device registry to match that of the driver so they sucessfully resolve.

2009-11-16at91: at91sam9g20ek modify dual slot evaluation kitNicolas Ferre
at91sam9g20ek rev. C and onwards embed two SD/MMC slots. This patch modify the previous dual slot board definition to match the official rev. C board. It also allows the use of at91_mci SD/MMC driver in addition to the atmel-mci one. Some pins have been re-affected from leds or Ethernet phy IRQ to the SD/MMC slot A. This lead to a modification of those definitions. Signed-off-by: Nicolas Ferre <nicolas.ferre@atmel.com> Acked-by: Andrew Victor <linux@maxim.org.za>
2009-11-13[ARM] Kirkwood: disable propagation of mbus error to the CPU local busLennert Buytenhek
Disable propagation of mbus errors to the CPU local bus, as this causes mbus errors (which can occur for example for PCI aborts) to throw CPU aborts, which we're not set up to deal with.

2009-11-13[ARM] pxa: fix interrupts number calculation when CONFIG_PXA_HAVE_ISA_IRQS=yMarc Zyngier
Commit d2c37068429b29d6549cf3486fc84b836689e122 ([ARM] pxa: initialize default interrupt priority and use ICHP for IRQ handling) broke ISA interrupt support on pxa27x/3xx. In such a case, PXA_IRQ(0) != 0, and the IRQ number computed from ICHP must be offset by PXA_IRQ(0). Tested on an Arcom Zeus (pxa270), with both CONFIG_PXA_HAVE_ISA_IRQS enabled and disabled.

2009-11-11omap3: Decrease cpufreq transition latencyMike Turquette
Adjust OMAP3 frequency transition latency from 10,000,000uS to a more reasonable 300,000uS. This causes ondemand and conservative governors to sample CPU load more often resulting in more responsive behavior. Tested on Android 2.6.29; using this value and conservative governor, CORE power consumption on Zoom2 was comparable to the old and unresponsive 10,000,000uS value while UI responsiveness was greatly improved.
