init: provide a generic free_initmem implementation

2019-05-14T16:47:47+00:00

Patch series "provide a generic free_initmem implementation", v2. Many architectures implement free_initmem() in exactly the same or very similar way: they wrap the call to free_initmem_default() with sometimes different 'poison' parameter. These patches switch those architectures to use a generic implementation that does free_initmem_default(POISON_FREE_INITMEM). This was inspired by Christoph's patches for free_initrd_mem [1] and I shamelessly copied changelog entries from his patches :) [1] https://lore.kernel.org/lkml/20190213174621.29297-1-hch@lst.de/ This patch (of 2): For most architectures free_initmem just a wrapper for the same free_initmem_default(-1) call. Provide that as a generic implementation marked __weak.

treewide: add checks for the return value of memblock_alloc*()

2019-03-12T17:04:02+00:00

Add check for the return value of memblock_alloc*() functions and call panic() in case of error. The panic message repeats the one used by panicing memblock allocators with adjustment of parameters to include only relevant ones. The replacement was mostly automated with semantic patches like the one below with manual massaging of format strings. @@ expression ptr, size, align; @@ ptr = memblock_alloc(size, align); + if (!ptr) + panic("%s: Failed to allocate %lu bytes align=0x%lx\n", __func__, size, align); [anders.roxell@linaro.org: use '%pa' with 'phys_addr_t' type] Link: http://lkml.kernel.org/r/20190131161046.21886-1-anders.roxell@linaro.org [rppt@linux.ibm.com: fix format strings for panics after memblock_alloc] Link: http://lkml.kernel.org/r/1548950940-15145-1-git-send-email-rppt@linux.ibm.com [rppt@linux.ibm.com: don't panic if the allocation in sparse_buffer_init fails] Link: http://lkml.kernel.org/r/20190131074018.GD28876@rapoport-lnx [akpm@linux-foundation.org: fix xtensa printk warning] Link: http://lkml.kernel.org/r/1548057848-15136-20-git-send-email-rppt@linux.ibm.com Signed-off-by: Mike Rapoport Signed-off-by: Anders Roxell Reviewed-by: Guo Ren [c-sky] Acked-by: Paul Burton [MIPS] Acked-by: Heiko Carstens [s390] Reviewed-by: Juergen Gross [Xen] Reviewed-by: Geert Uytterhoeven [m68k] Acked-by: Max Filippov [xtensa] Cc: Catalin Marinas Cc: Christophe Leroy Cc: Christoph Hellwig Cc: "David S.

unicore32: stop printing the virtual memory layout

2019-03-08T02:32:03+00:00

Since commit ad67b74d2469 ("printk: hash addresses printed with %p"), the virtual memory layout printed during boot up contains "ptrval" instead of actual addresses. Instead of changing the printing to "%px", and leaking virtual memory layout information again, just remove the printing completely, cfr. e.g. commits 071929dbdd86 ("arm64: Stop printing the virtual memory layout") and 31833332f798 ("m68k/mm: Stop printing the virtual memory layout"). All interesting information (actual section sizes) is already printed by mem_init_print_info() just above anyway.

arch: simplify several early memory allocations

2019-03-08T02:32:03+00:00

There are several early memory allocations in arch/ code that use memblock_phys_alloc() to allocate memory, convert the returned physical address to the virtual address and then set the allocated memory to zero. Exactly the same behaviour can be achieved simply by calling memblock_alloc(): it allocates the memory in the same way as memblock_phys_alloc(), then it performs the phys_to_virt() conversion and clears the allocated memory. Replace the longer sequence with a simpler call to memblock_alloc().

arch: Move initrd= parsing into do_mounts_initrd.c

2018-11-26T21:50:45+00:00

ARC, ARM, ARM64 and Unicore32 are all capable of parsing the "initrd=" command line parameter to allow specifying the physical address and size of an initrd. Move that parsing into init/do_mounts_initrd.c such that we no longer duplicate that logic. Signed-off-by: Florian Fainelli Reviewed-by: Mike Rapoport Signed-off-by: Rob Herring
