s390/sclp: fix declaration of _sclp_print_early()

2015-01-08T09:02:51+00:00

_sclp_print_early() has return value: at present, return 0 for OK, 1 for failure. It returns '%r2', so use 'long' as return value (upper caller can check '%r2' directly). The related warning: CC arch/s390/boot/compressed/misc.o arch/s390/boot/compressed/misc.c:66:8: warning: type defaults to 'int' in declaration of '_sclp_print_early' [-Wimplicit-int] extern _sclp_print_early(const char *); ^ At present, _sclp_print_early() is only used by puts(), so can still remain its declaration in 'misc.c' file.

s390/string: provide asm lib functions for memcpy and memcmp

2012-09-26T13:44:50+00:00

Our memcpy and memcmp variants were implemented by calling the corresponding gcc builtin variants. However gcc is free to replace a call to __builtin_memcmp with a call to memcmp which, when called, will result in an endless recursion within memcmp. So let's provide asm variants and also fix the variants that are used for uncompressing the kernel image. In addition remove all other occurences of builtin function calls.

[S390] support XZ compressed kernel

2011-03-15T16:08:24+00:00

Add support for XZ compressed kernel. Same as on x86 and sh. Signed-off-by: Heiko Carstens Signed-off-by: Martin Schwidefsky

[S390] correct ipl parameter block safe guard

2011-02-17T12:13:59+00:00

The 'output' variable is passed from decompress_kernel to check_ipl_parmblock before it is initialized. That disables the safe guard against the overwrite of the ipl parameter block. Fix this by passing the correct value to check_ipl_parmblock. Reported-by: David Binderman Signed-off-by: Martin Schwidefsky

[S390] fix boot failures with compressed kernels

2010-03-24T10:49:54+00:00

Fix two bugs with the kernel image compression: 1) reset the bss section of the compressed vmlinux 2) clear the high half of the registers for 64 bit early enough for the decompression step Signed-off-by: Martin Schwidefsky

[S390] add support for compressed kernels

2010-02-26T21:37:33+00:00

Add the "bzImage" compile target and the necessary code to generate compressed kernel images. The old style uncompressed "image" target is preserved, a simple make will build them both. Signed-off-by: Martin Schwidefsky
