2015-12-15ARM: debug-ll: rework lpc32xx handlingArnd Bergmann
LPC32xx can not yet be configured in a multiplatform kernel, but if we ever get there, enabling one of the LPC32xx platforms while trying to use DEBUG_LL for another platform can default to the wrong UART address, as the options are purely based on the architecture being enabled or not. This changes the logic to use the LPC32xx default addresses only if we have also picked the respective Kconfig symbols introduced here. While we're at it, this also reorders the virtual address as it should be. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Acked-by: Vladimir Zapolskiy <vz@mleia.com>
2015-12-15ARM: debug-ll: rework gemini handlingArnd Bergmann
Gemini can not yet be configured in a multiplatform kernel, but if we ever get there, enabling one of the gemini platforms while trying to use DEBUG_LL for another platform can default to the wrong UART address, as the options are purely based on the architecture being enabled or not. This changes the logic to use the gemini default addresses and the flow control settings only if we have also picked the respective Kconfig symbols introduced here. While we're at it, this also reorders the virtual address as it should be. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Acked-by: Hans Ulli Kroll <ulli.kroll@googlemail.com>
2015-12-15ARM: debug-ll: rework integrator/versatile handlingArnd Bergmann
Enabling one of the integrator platforms in a multiplatform kernel while trying to use DEBUG_LL for another platform can default to the wrong UART address, as the options are purely based on the architecture being enabled or not. This changes the logic to use the integrator default addresses only if we have also picked the respective Kconfig symbols introduced here. Versatile is not yet part of multiplatform, but hopefully soon will be, so we do the same change for versatile as well. Signed-off-by: Arnd Bergmann <arnd@arndb.de>

Enabling one of the SPEAr platforms in a multiplatform kernel while trying to use DEBUG_LL for another platform can default to the wrong UART address, as the options are purely based on the architecture being enabled or not.

2015-12-15ARM: debug-ll: rework ep93xx handlingArnd Bergmann
This makes ep93xx debug-ll handling more consistent with the other platforms, by adding a separate Kconfig symbol for it that in turn selects the standard DEBUG_UART_PL01X symbol. We still have to pick a physical address even if DEBUG_LL is disabled here, because the EP93xx uncompress output code uses CONFIG_DEBUG_UART_PHYS. If we ever move to multiplatform support, this can go away. Signed-off-by: Arnd Bergmann <arnd@arndb.de>
2015-12-15ARM: debug-ll: reorganize mvebu debug uart configArnd Bergmann
As we are moving dove/mv78xx0/orion into multiplatform, the debug-ll configuration options for these platforms are conflicting with the multiplatform configuration: enabling one of those platforms sometimes changes the default addresses to the ones used on one of them, rather than the one that was selected in Kconfig. This changes the configuration so we share the physical address configuration with mach-mvebu. Signed-off-by: Arnd Bergmann <arnd@arndb.de>
2015-12-15ARM: debug-ll: fix UART configuration with ARCH_KEYSTONEArnd Bergmann
We may have multiple platforms enabled and also DEBUG_LL configured for one of them. However if we enable ARCH_KEYSTONE, we default to using 32-bit UART access independent of which platform we are actually using, which can be confusing. This changes the logic so the 32-bit default gets only used by default if we actually configure the keystone UART, as opposed to picking some other 8250 setting on a kernel that has keystone support enabled.

2015-12-15Revert "scatterlist: use sg_phys()"Dan Williams
commit db0fa0cb0157 "scatterlist: use sg_phys()" did replacements of the form: phys_addr_t phys = page_to_phys(sg_page(s)); phys_addr_t phys = sg_phys(s) & PAGE_MASK; However, this breaks platforms where sizeof(phys_addr_t) > sizeof(unsigned long).

After grepping for it (using the correct spelling), and not finding it, I noticed how the debug printk was just misspelled. Fix it. The actual mapping bug that Pavel reported is still open.

2015-12-15arm64: reduce stack use in irq_handlerJames Morse
The code for switching to irq_stack stores three pieces of information on the stack, fp+lr, as a fake stack frame (that lets us walk back onto the interrupted tasks stack frame), and the address of the struct pt_regs that contains the register values from kernel entry. (which dump_backtrace() will print in any stack trace). To reduce this, we store fp, and the pointer to the struct pt_regs. unwind_frame() can recognise this as the irq_stack dummy frame, (as it only appears at the top of the irq_stack), and use the struct pt_regs values to find the missing interrupted link-register.

While the userspace interface requests the maximum size the gmap code expects to get a maximum address. This error resulted in bigger page tables than necessary for some guest sizes, e.g. a 2GB guest used 3 levels instead of 2. At the same time we introduce KVM_S390_NO_MEM_LIMIT, which allows in a bright future that a guest spans the complete 64 bit address space. We also switch to TASK_MAX_SIZE for the initial memory size, this is a cosmetic change as the previous size also resulted in a 4 level pagetable creation.

2015-12-15ARM: davinci: fix a problematic usage of WARN()Geliang Tang
WARN() takes a condition and a format string. The condition was omitted. So I added it. Signed-off-by: Geliang Tang <geliangtang@163.com> Signed-off-by: Sekhar Nori <nsekhar@ti.com>
2015-12-15ARM: davinci: only select WT cache if cache is enabledArnd Bergmann
The DA830 chip only works if the dcache is in writethrough mode, but that produces a harmless Kconfig warning if the cache happens to be disabled: warning: (ARCH_DAVINCI_DA830) selects CPU_DCACHE_WRITETHROUGH which has unmet direct dependencies ((CPU_ARM740T || CPU_ARM920T || CPU_ARM922T || CPU_ARM925T || CPU_ARM926T || CPU_ARM940T || CPU_ARM946E || CPU_ARM1020 || CPU_FA526) && !CPU_DCACHE_DISABLE) This makes the select conditional so we don't have to worry about the warning in randconfig builds any more.
