2010-01-19ARM: 5886/1: arm: Fix cpu_proc_fin() for proc-v7.S and make kexec workTony Lindgren1-1/+8
The comments in arm_machine_restart() suggest that cpu_proc_fin() will clean and disable cache and turn off interrupts. This does not seem to be implemented for proc-v7.S, implement it the same way as for proc-v6.S. This also makes kexec work for v7. Note that a related TLB and branch traget flush patch is also needed to avoid kexec "crc error". Note that there are still some issues that seem to be related to L2 cache being on and causing occasional uncompress "crc error" with kexec. Anyways, this gets kexec mostly working on V7 for now.

Without this patch arch/arm/compressed/head.S defaults to generic DCC code that does not work for v7. For more information on the v7 DCC, see Cortex-A8 TRM "12.11.1 Debug communications channel". To use it with post 2.6.33-rc1 or later, you need to have: CONFIG_DEBUG_LL=y ONFIG_DEBUG_ICEDCC=y CONFIG_EARLY_PRINTK=y Earlier kernels need commit 93fd03a8c6728b58879f8af20ffd55d9c32a778b backported.

2010-01-19sh64: wire up sys_accept4.Paul Mundt2-1/+3
sh64 on the other hand provides both direct broken out syscalls as well as socketcall access. As there are binaries that use both socketcall has to stay around. The current ABI prefers direct syscalls. It was pointed out that when sys_recvmmsg was added in, sys_accept4 was overlooked. This takes care of wiring it up.

2010-01-19x86, apic: use logical flat for systems with <= 8 logical cpusSuresh Siddha2-19/+4
We can use logical flat mode if there are <= 8 logical cpu's (irrespective of physical apic id values). This will enable simplified and efficient IPI and device interrupt routing on such platforms. This has been tested to work on both Intel and AMD platforms. Exceptions like IBM summit platform which can't use logical flat mode are addressed by using OEM platform checks.

2010-01-19x86, apic: use physical mode for IBM summit platformsSuresh Siddha1-0/+5
Chris McDermott from IBM confirmed that hurricane chipset in IBM summit platforms doesn't support logical flat mode. Irrespective of the other things like apic_id's, total number of logical cpu's, Linux kernel should default to physical mode for this system. The 32-bit kernel does so using the OEM checks for the IBM summit platform. Add a similar OEM platform check for the 64bit kernel too. Otherwise the linux kernel boot can hang on this platform under certain bios/platform settings.

2010-01-18ARM: 5883/1: Revert "disable NX support for OABI-supporting kernels"Rabin Vincent1-9/+0
This reverts commit 14f0aa359365e8a93a77b71e3b840274b9b4dcb1. That commit was needed earlier because system call restarting for OABI (compat) required an executable stack and thus had problems with NX. Since ab72b00734ae4d0b ("ARM: Fix signal restart issues with NX and OABI compat") has reworked the code to not require an executable stack anymore, we can re-enable NX support for kernels with OABI (compat) support.

flush(void) Because of the include of the decompress_inflate.c file from boot/compress/misc.c, there are different flush() defines: In file included from arch/arm/boot/compressed/misc.c:249: arch/arm/boot/compressed/../../../../lib/decompress_inflate.c:138:29: error: macro "flush" passed 2 arguments, but takes just 0 Fix this by removing the define of flush() in misc.c for CONFIG_DEBUG_ICEDCC as it's already defined in mach/uncompress.h, and that is being included unconditionally. Also use a static inline function instead of define for mach-mxc and mach-gemini to avoid similar bug for those platforms.

2010-01-16m68knommu: fix invalid flags on coldfire pit clocksourcejohn stultz1-1/+0
The m68knommu coldfire pit clocksource looks like it was incorrectly marked as a continuous clocksource. Running with it marked as a continuous clocksource could cause hangs when the system switches to highres mode or enables nohz. This patch removes the CLOCK_SOURCE_IS_CONTINUOUS flag on the coldfire pit clocksource. This will disallow systems using this clocksource from entering oneshot mode (disabling highres timers and nohz).

Commit 57b150cce8e004ddd36330490a68bfb59b7271e9 (irq: only update affinity if ->set_affinity() is sucessfull) broke xics irq affinity. We need to use the cpumask passed in, instead of accessing ->affinity directly. Signed-off-by: Anton Blanchard <anton@samba.org> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
2010-01-15powerpc/swsusp_32: Fix TLB invalidationAnton Vorontsov1-1/+1
It seems there is a thinko in the TLB invalidation code that makes the tlbie in the loop executed just once. The intended check was probably 'gt', not 'lt'. Signed-off-by: Anton Vorontsov <avorontsov@ru.mvista.com> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
2010-01-15powerpc/8xx: Always pin kernel instruction TLBJoakim Tjernlund1-4/+4
Various kernel asm modifies SRR0/SRR1 just before executing a rfi. If such code crosses a page boundary you risk a TLB miss which will clobber SRR0/SRR1. Avoid this by always pinning kernel instruction TLB space. Signed-off-by: Joakim Tjernlund <Joakim.Tjernlund@transmode.se> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
