The current implementation of get_user_desc() sign extends the return value because of integer promotion rules. For the most part, this doesn't matter, because the top bit of base2 is usually 0. If, however, that bit is 1, then the entire value will be 0xffff... which is probably not what the caller intended. This patch casts the entire thing to unsigned before returning, which generates almost the same assembly as the current code but replaces the final "cltq" (sign extend) with a "mov %eax %eax" (zero-extend). This fixes booting certain guests under KVM. Signed-off-by:

Not a single line of actual code in the function was really fundamentally correct. Problems ranged from lack of proper range checking, to removing the last character written (which admittedly is usually '\n'), to not accepting hex numbers even though the 'show' routine would show the data in that format. This tries to do better. Acked-by:

Patch f598282f exposed a problem in powerpc MSI-X functionality, making network interfaces such as ixgbe and cxgb3 stop to work when MSI-X is enabled. RX interrupts were not being generated.

This patch fixes two issues in the procfs stack information on x86-64 linux. The 32 bit loader compat_do_execve did not store stack start. (this was figured out by Alexey Dobriyan). The stack information on a x64_64 kernel always shows 0 kbyte stack usage, because of a missing implementation of the KSTK_ESP macro which always returned -1. The new implementation now returns the right value. Signed-off-by:

Building with --build-id option, .note.gnu.build-id section is added to vmlinux.bin. But some old buggy binutils creates a huge vmlinux.bin, and a bootloader fails to boot its zImage as well. This patch adds a NOTES macro to a linker script vmlinux.ld.S to put .note.gnu.build-id section into .note section. Then, the .note section will be removed, because "-R .note" option is specified in OBJCOPYFLAGS to make a vmlinux.bin binary. Signed-off-by:
